Updated Lada Granta with a gun: test drive and giveaway of three cars!

Slightly updated interior

We have talked about the Granta salon more than once. There are not many changes in the updated version. The designers redesigned the instrument panel; as a result, the gearbox operation indication has moved and is now displayed above the fuel reserve scale. The shelf on the front panel on the passenger side disappeared from view. Now it is covered by the glove compartment lid. But for some reason the lid of the convenient drawer at the top of the panel is made of plastic in the wrong color, which causes slight irritation. A 12V socket took the place of the cigarette lighter.

There are also nice little things - three headrests in the back row, for example. They are not very high and do not interfere with the view to the rear through the interior mirror. There are hooks on the handles under the ceiling. There is a belt for the middle passenger with a well-thought-out fastening. True, it’s uncomfortable to sit in the back - the Granta remains a cramped car. Only a child or a miniature adult can fit behind the driver. There is a hum in the cabin, which, of course, is annoying. We can only hope that this is a feature of the Grant with its 98-horsepower engine.

List of necessary tools for changing oil in manual transmission

Spacious trunk

The only victory that the manufacturer won over the space inside the Granta is related to the trunk. It's really big. The trunk opens with a button, like on Vesta. The walls behind the rear seats, like in a sedan, are no longer here. A very convenient rigid shelf that can be folded or removed altogether. A quality item, just like on foreign cars - no joke! Soft floor, full-size spare wheel. In general, nothing special, but you wouldn’t expect anything else from such a car. If you like to carry bulky luggage, Granta can help you. The car is guaranteed to fit, for example, a 170 cm long bathtub - tested from personal experience. The only confusing thing is that the trunk door is closed with a loop fastened with a self-tapping screw. It looks clumsy.

Automatic transmission reliability and service life

The Jatco JF414E hardware design is simplified as much as possible, which reduces the risk of difficult-to-fix problems. Still, the machine is not without “childhood diseases” that manifest themselves during the running-in stage. The needle bearing of the pump hub is clamped until it is completely destroyed. Car owners often encounter this problem with a mileage of 6-15 thousand km.

The design of the Jatco JF414E assumes a fairly large margin of safety. The box can serve 200-400 thousand km without major repairs. The service life of an automatic transmission is usually exhausted after a million kilometers. In this case, the unit requires a complete overhaul and major overhaul.

The electronic control unit may fail after a mileage of 150-200 thousand km. The main cause of failure is external influence. The risk of firmware damage is extremely low.

The central double-row bearing often fails after a mileage of 60-130 thousand km. It usually breaks down due to overloads caused by driving with vibrations at high speeds.

Oil seals begin to leak after a mileage of more than 90 thousand km. This is often due to the use of oil that is not suitable for specific climate conditions.

The entire hydraulic unit rarely fails. Its replacement may be required when the mileage exceeds 400-500 thousand km. At the same time, at a mileage of 70-100 thousand km, gaskets and solenoids may need to be replaced. This is usually caused by dirty oil and frequent overheating. With a mileage of more than 120 thousand km, it may be necessary to install new sensors due to their damage by steel chips in contaminated oil.

Some car owners are faced with the problem of damage to the pan body. It can get crushed from being hit by a stone, despite the presence of underbody protection and decent ground clearance of the Lada Grant.

Clutches wear out depending on the aggressiveness of your driving style. Their replacement under normal conditions is required when reaching 150-250 thousand km. It is also advisable to install new Teflon rings during repairs.

Technical equipment

The main feature of the Grant with 1.6 liter engines is that they are “plug-inless”. The pistons are recessed so that if the belt breaks, the valves do not meet the piston. Paired with such an engine, the Grant is equipped with a simple and reliable 4-speed automatic transmission, specially adapted for this car. The selector has modes P, R, D, “1” and “2” with a prohibition of transition, respectively, above the first or second gear. There is a button to turn off overdrive. Top trim levels are equipped with heated front seats (albeit single-stage) and windshield heating. The ERA-GLONASS system has been installed.

Updated Lada Granta with a gun: test drive and giveaway of three cars!

Sergey Znaemsky tested the Lada Granta with a Jatco automatic transmission: how does it drive?

I saw the steam locomotives on the site of the VAZ Technical Museum - and it clicked in my head: you couldn’t find a better backdrop for a portrait of Granta with a machine gun! He grabbed the phone and began calling the administration, begging them to let the car into the closed area. On Saturday. In the evening. Luckily, VAZ top engineer Oleg Grunenkov had an “all-terrain vehicle” pass with access to any corner of AvtoVAZ. But Oleg sighed doomedly: “Once again it turns out that Granta is archaic, like a steam locomotive, with the same efficiency...

The invitation letter arrived at the editorial office in early July, and it said that acquaintance with the “automatic” Granta would take place in Togliatti in the middle of... June! I didn’t have time to figure out who exactly was a month late - the VAZ team or the email, because right there in the event program I discovered even more intriguing dates: departure from Moscow - May 19, return - July 22. Two months in Togliatti?

The matter, of course, turned out to be banal typos: the first commercial Ladas with automatic transmissions rolled off the VAZ assembly line on July 19 of this year.

- Get ready! Our car will go through five bodies!

Under the hood, the gearbox is located traditionally, to the left of the engine. The “automatic” is 33 kg heavier than the “manual”, and 33 new parts appeared in the car itself, so the weight of the Grant increased by 45 kg and the front springs had to be made a little stiffer. The engine mounts were strengthened, the front suspension stretch on the left side was changed, and a new radiator was installed. The external CV joints on the “automatic” Grant are the same as on cars with “mechanics”, and the joints connecting the drive shafts to the gearbox are Tripod type (they have larger working angles). The automatic has a final drive with a ratio of 4.08. The transmissions on the Grants will be filled with Nissan Matic S fluid. The electronic transmission control unit is located in the wheel arch under the left front headlight. To ensure reliability, the Japanese put forward a requirement to increase the rigidity of the power unit - there are now not four, but six mounting points between the engine and transmission. For the same reason, the VAZ engine has a new cast pan. And the box itself has a stamped pallet. This is precisely the lowest point: the ground clearance was reduced to 140 mm and during testing, the VAZ team, having hit a boulder, still broke one box. There is no factory protection for the engine compartment, except for a plastic boot.

VAZ workers were fussing, reporters were crowding, assemblers were trying to get into work places. And now, across the expanses of the Kalinovsky assembly shop, a silver Grant floats onto the core of the assembly line. Under camera flashes, a 1.6 six-valve engine with a docked hydromechanical transmission from the Japanese company Jatco was brought up to it.

The technological term “marriage,” which is commonly used to describe the connection of a body with a power unit, has always given rise to piquant associations, and this case is no exception. Firstly, in the matter of introducing the “automatic”, AvtoVAZ itself, by all indications, acted rather in the role of a bride, and secondly, the morning after the ceremony, the Volzhsky Automobile Plant officially celebrated its birthday: the young man turned forty-six. Is a Lada with an automatic transmission a belated woman's happiness?

While automatic Grants are moving along the conveyor belt at long intervals, by the end of August they will only make a batch for dealer showrooms. By the beginning of next year, 10 thousand cars should be assembled, and next year - already 70 thousand, that is, every seventh Lada produced will be equipped with an automatic transmission. But Grants will be in the minority among these cars - the role of the main “car carrier” will go to the prettier new Kalina. But Granta is the most affordable car with an automatic transmission on the Russian market!

“ZAZ Chance and Chery Indis are not our competitors,” assures Oleg Khromkov, who led the introduction of Japanese automatic transmission at VAZ. — The “Chinese” has a “robot”, and it pulls, and Chance is almost 50 thousand more expensive.

At VAZ they say that without Oleg Khromkov there would be no “automatic”. A graduate of the Kuibyshev Aviation Institute (now Samara Aerospace University), Khromkov in the late 80s was engaged in calibrating engines for toxicity at VAZ and working on sports cars, but in 2006 he set out on his own and “swimmed” to the position of director of SeAZ. And three years ago he returned and headed the work on integrating the Japanese transmission. Based on his vocabulary, his command of English, and even his ability to choose a dress code, one gets the impression that Khromkov is one of some new breed of VAZ specialists

The Lada Granta for 373 thousand 300 rubles has a hydromechanical four-speed automatic transmission model JF414E, the oldest and simplest of those that Jatco offers for engines with a displacement of more than one liter. True, the transmission has recently undergone modernization, but still only two cars in the world are equipped with this transmission - our Granta and the Chinese-assembled Nissan March (aka Micra). VAZ doesn’t hide the fact that to make it cheaper, they chose a simpler transmission, and the fact that the design is not new can be regarded as a guarantee of reliability.

In the summer of 2010, when VAZ finally realized that the “automatic” needed to be launched either now or never again, the short list of candidate boxes, in addition to the Jatco unit, included Logan’s “automatic” DP0, as well as the FT702 transmission from the Moscow company KATE. The same “innovative” seven-speed planetary transmission without a torque converter, which for the last five years Maxim Nagaytsev, former vice-president of AvtoVAZ, current head of NAMI, and part-time co-investor of KATE, promised to launch into series. One Kalina with such an “automatic” even took part in evaluation tests: the power unit showed a tendency to overheat, and that was the end of it. Moreover, VAZ workers say that there was no real deadline for completing work on this box.

The French “automatic” was rejected because, at a similar cost, it was even less modern than the Japanese one.

The 2010 Jatco JF414E automatic transmission is the result of the only modernization of the four-speed gearbox that first appeared on the Nissan Sunny in 1989. Over 22 years, more than 11 million of these transmissions have been produced. The modernization did not affect the architecture: the use of new materials and technologies made it possible to reduce the body length by 11% and make the unit 15% lighter

By the way, Jatco offered AvtoVAZ a new generation X-tronic variator, but it turned out to be 20% more expensive than a hydromechanical transmission, although it provides a gain in fuel consumption of 1 l/100 km. The variator was postponed for the future. Grant's automatic transmission does not have sports or winter modes, nor does it have the ability to change gears manually. But the plastic on the handle is elastic and pleasant, there is a leatherette “apron” and the selector moves with noble effort. In general, there is no shame. And if you remember the “poker” of Logan’s “automatic machine”... On the other hand, in Grant’s plastic furniture, the lever of the new transmission looks like a Faberge egg at a roadside market.

The design of the transmission selector is VAZ, but the supplier is foreign. The lever is higher than that of the “mechanics”, the strokes are small, the groove is straight and it’s easy to miss the Drive position, especially if you’re not used to it. In positions 1 and 2, the transmission limits shifts above the indicated gears. On the left at the base there is an “overdrive off” button - disabling fourth gear

Although there is already air conditioning and a passenger airbag. In addition to them, especially for the version with an automatic transmission, ABS and all sorts of little things like ceiling handles for rear passengers have been added to the standard Norma equipment. There is no radio, however.

Corporate communication in Togliatti style - right during the journalistic presentation, AvtoVAZ Vice President for Sales and Marketing Artem Fedosov (left) convinces the head of Jatco in Russia Tadashi Yasuda (right) to organize the collection of “warranty” boxes through VAZ’s subsidiary Lada-Service

For now, all automatic Grants will be produced only in this expanded Norma Plus configuration. The Luxury version will appear later - there will be “music”, and with a multimedia screen, and a “color” instrument panel, and a stabilization system.

AvtoVAZ outlined the “consumer value” of an automatic transmission at 35 thousand rubles, so we can safely estimate that the luxury Granta will cross the threshold of 400 thousand rubles. Kalina with an automatic transmission will be even more expensive. Priora? Implanting an “automatic machine” into its outdated design would be too expensive - it will only receive it with a future change of generations.

“I have seven meetings per working day.” Oleg Grunenkov started as an ordinary designer, and at the age of forty he became the head of the most important projects for the company: Kalina, Granta, Datsun. Grunenkov is also one of the “new” VAZ top engineers - he takes a sober look at AvtoVAZ products, is savvy on economic issues and says that on his own initiative he went to study for an MBA course

AvtoVAZ spent little to “marry” the automatic transmission with its own engine: about 17 million euros. The contract with Jatco is for three years with the right to extend; the Japanese will supply fully assembled transmissions to AvtoVAZ from a plant in Fuji. If the question of their production in Russia arises, it will be provided that sales exceed 100 thousand cars per year. In the meantime, the Japanese company has only opened a representative office in our country.

Responsible for cooperation with AvtoVAZ and therefore now living in Tolyatti, Tadashi Yasuda, when asked what was the most difficult thing in working on the VAZ project, answers this way: to satisfy the needs of local consumers.

While setting up the transmission, the VAZ team turned to the Austrian company AVL for help. The starting point was the automatic transmission on the Nissan Note hatchback. But the “relaxed” Japanese calibrations, which were initially proposed by Jatco and AVL, did not suit the VAZ team.

“The response to the pedal, the operation of the box when starting off - everything turned out smoothly, like on an electric locomotive,” explains Khromkov. — The difference in driving philosophy and mentality! They drive small budget cars slowly, but here...

And for Granta and Kalina with automatic transmissions, we have specially selected the most powerful possible engine - a 98-horsepower sixteen-valve VAZ-21126 with a lightweight connecting rod and piston group. With the support of the Austrians from AVL, the VAZ team adapted the automatic calibrations in their own way: as they say, “to suit the driver’s driving philosophy.” And, presumably, it was not without reason that journalists were released onto the karting track ring for the first trip.

It was then, I think, that Yasuda-san understood everything about the needs of local consumers, especially after one of the journalists took him for a ride as a passenger - senselessly and mercilessly, with the handbrake, with smoke coming from under the wheels... I bet: getting out from the car, the green-faced Japanese was thinking precisely about the difference in mentalities.

“As if we wouldn’t have to look for an alternative supplier,” VAZ engineers joked behind their backs.

The bar with the automatic mode symbols near the lever is not illuminated, so the only visual indication of the transmission’s operation is in the upper right corner of the display on the instrument panel. Both the transmission mode and the number of the gear used are reflected here. By the way, the Japanese gearbox has what VAZ people call “virtual fifth gear.” The bottom line is that if in fourth gear and a speed above 50 km/h the driver begins to accelerate at half pedal, the box does not go down, but remains in top gear and briefly unlocks the torque converter to increase torque. The car drives as if with the clutch half depressed - this is noticeable only by the tachometer needle, which jumps by almost 1000 rpm

I started Granta with caution - my arms and legs still remembered the sedan in the Standard configuration, which we recently had at our editorial office for a “fitting”.

I started it, drove off and realized: “automatic”, air conditioning and power steering - here it is, a simple formula for a humane Lada. The Jesuit “ten-wheel mechanics” disappeared, many of the controls with which the driver came into contact changed, and Granta blossomed. And let the VAZ drivers not be modest: they say, “simpler and cheaper” - even on famous foreign cars, the rare hydromechanical “automatic” is configured as nicely as on the Lada!

In response to the first light press of the accelerator, the car starts moving without delay, then vigorous acceleration, logical soft transitions up and fast, without hesitation, down. The performance of the power unit when driving in the city is almost exemplary. Even though the dynamics have suffered and instead of 11.6 seconds, acceleration to hundreds takes 13.5 seconds, now these seconds still fly by, and do not drag on painfully.

The front suspension springs here are a little stiffer than on a regular Grant - the car is 45 kg heavier, but this has practically no effect on driving comfort. The suspension swallowed all the potholes, and still swallows, and the interior, as if it had all the guts of the front panel, still does.

Peppy both in the middle and at the top, the sixteen-valve engine is relatively quiet only up to 4500 rpm. It’s easy to comfortably maintain a speed of 120 km/h with it, but it comes out with a war cry for every intense overtaking.

I still don’t want to accelerate over 130 km/h. With both a short steering rack (3.1 turns from lock to lock) and ABS, the Grant chassis remained sagging and had sluggish brakes. A new vacuum booster with an “additional brake booster”, which increases the pressure in the system as it slows down, gave the brake pedal a thoroughbred rigidity, but the brake mechanisms themselves did not change. As a result, you have to press the pedal harder, but the Grant slows down just as reluctantly, and the ABS kicks in much later than the moment the wheels lock.

Oleg Grunenkov, who supervises all work on Kalina and Grant, says that all the problems are familiar to him and that next year the Grant chassis will be modernized. The brakes will be strengthened, the electric booster will be adjusted (to get rid of the void in the “zero”), and modified springs, shock absorbers and stabilizers will appear in the suspension.

Reliability? The standard service life of the “machine gun,” according to the Japanese, is ten years. But the factory warranty for such a Granta with automatic transmission is the same as for cars with manual transmission: three years or 50 thousand kilometers. The transmission cannot be repaired at dealership centers - equipment and training of servicemen require money and time, so at first AvtoVAZ will replace the defective gearboxes entirely, and Avtoframos will restore them. It looks like it will be done in the near future: by the end of the day, my car from the pilot series began to howl in second gear and tremble slightly at idle.

But still.

Three hundred seventy-three thousand rubles is less than for a Priora with a “mechanics” in a similar Norma configuration. At the same time, Granta is the first VAZ car in a long time that does not justify itself by being cheap, but seems to promise the buyer a good deal. This is the first Lada worthy of its price.

And not only Lada.

The Granta with an automatic transmission is almost like a Datsun sedan, which we will start selling in 2014. Nissan didn't just buy the rights to the VAZ platform - they borrowed the car almost entirely.

Air conditioning, passenger airbag, ABS and other delights of the Norma Plus package, alas, did not change the Granta’s interior much. The Luxury version is promised at the end of the year

A year and a half before the Grant appeared, Nissan adopted a strategy according to which budget cars should be developed not globally, but locally - using production sites and technical resources of the countries to which they are targeted. In Russia, the Japanese then incognito purchased five Kalinas, which were sent to England for testing. The result was devastating - handling, brakes, noise and vibration... But the summary stated that after modifications, the AvtoVAZ platform could be used to produce Nissan cars. The Japanese asked Tolyatti for a development strategy - and the VAZ team showed Nissan their Grants project.

The same Grunenkov is now leading the development of Datsun. The car will have Japanese decorative elements in the front and rear, and almost all the equipment will be ours, including the body, chassis and even engines. It was decided to install the VAZ eight-valve engine with manual transmission on the base Datsun, and the same sixteen-valve VAZ-21126 with a Jatco automatic transmission, as on the Grant and Kalina, on the more expensive version.

I say: “Datsun” - and Grunenkov’s eyes light up in a way that the VAZ team didn’t light up after the French from Renault appeared in Togliatti.

— Working with the Japanese is very interesting! French partners from Renault are strong in marketing, planning, and working with suppliers. And the Nissan team captivates with its approach to engineering. We are gaining enormous experience.

I listen to Grunenkov and it’s like I’m putting together a big VAZ puzzle. It becomes clear why the issue with the “automatic machine,” which the factory could not remove for decades, was suddenly resolved in just two years. And why was this particular “automatic” chosen? And even why my invitation included three different dates!

Having “hooked” Nissan, Granta pulled the entire plant along with her.

It was the Japanese who essentially lobbied for the choice of an automatic transmission from Jatco, which is 75% owned by Nissan. And Jatco itself, in turn, set the pace of work on the “automatic” Grant - 16 months.

True, VAZ did not believe that the “automatic” would be ready on time. Both the press service and even top managers, according to the old tradition, were counting on a delay and were waiting for a finished car with an automatic transmission in August or September. And Oleg Khromkov’s team completed the project in July, only four days behind schedule.

Other programs have also been shaken up. Since the automatic transmission is ready, there is no point in delaying the launch of the updated Kalina, for which the transmission was selected. There is no place to further delay the introduction of the VAZ-2180 manual gearbox with cable drive, which should have appeared two years ago (AR No. 9, 2010), the modernization of the Grant chassis is just around the corner...

As we know, the experience gained in the past cooperation with Porsche was enough for the VAZ team for three decades. And Nissan is going to de jure become a co-owner of AvtoVAZ in the near future - through a newly formed joint venture with the Russian Technologies company, the Japanese will get 15% of the capital. And it seemed to me that this merger was perceived at the plant as recognition. Not as a threat to identity, but as hope for it. Like a ticket to the future.

A locomotive—that’s what I was thinking about when I brought Lada to the locomotive. Well, the fact is that in the VAZ museum there was no more modern model... Maybe someday, for example, a Sapsan train will appear among the exhibits - then I’ll definitely take a photo of the next new Lada against its background. Or Datsun.

Features and characteristics of the machine gun on Grant

Acceleration to hundreds is 13.3 seconds. Maximum speed 173 km/h. The performance is non-racing and doesn’t smell like the luxury class, but the car is also a budget car, quite enough for the city and the highway.

The main element is the automatic transmission control lever, which is made in the traditional form for cars 20 years ago. The shifters, in which the gears were switched sequentially, could cause problems due to driver errors when changing gears - you could simply skip the right one. Modern ones are made in the form of ladders. Such technical solutions eliminate the problem of incorrect switching. A cable is responsible for shifting gears; although this scheme is a bit old, it is reliable.

A system of protection against unauthorized activation has been implemented. When driving at speed, the wrong gear (for example, reverse when moving forward) will not be engaged. This system is controlled by an electronic unit.

Automatic transmission for Lada Granta

The firmware installed on the control unit most likely differs from Nissan’s: after all, VAZ’s engines are different.

The automatic modes on the Lada Granta are traditional; no instructions are required:

R – reverse mode;

N – neutral gear;

D – forward movement to maximum gear;

2 – move forward to second gear;

1 – forward movement only in first gear.

The machine controls the electronic control unit (firmware is installed into it), it is responsible for the acceleration and switching characteristics. The automatic transmission control unit and the engine control unit interact in pairs.

There is protection against overheating (114 C), and the gear lights up. In conditions of negative temperatures, it is recommended to warm up the automatic transmission and engine by holding the car on the brake with the gear engaged, otherwise problems will soon arise with the gearbox. Until the box warms up, higher gears and torque converter locking will not engage. The locking mode is activated by the torque converter in 3rd and 4th gears.

Features of operating a car with automatic transmission

The JF414E is configured to mechanically activate only the parking mode, all others are activated electronically. It is not recommended to turn on “Parking” when the car is located on a slope. In this case, you must use the handbrake.

Dashboard Lada Granta

The technical characteristics of the Lada Granta automatic transmission Jatco JF414E (AY-K3) allow us to classify the car as a million-dollar vehicle, that is, with a gearbox service life approaching 1,000,000 km.

VAZ defines the resource more modestly: 200 – 400 thousand km. But with a caveat: with correct operation and timely service.

About automatic transmission maintenance

Transmission fluid must be replaced after 60,000-80,000 km. It makes sense to purchase a branded transmission, and not necessarily a very expensive one. JF414 is almost omnivorous and allows the use of not only the original Matic-S (EJ-1 ATF), but also substitutes such as Dexron VI.

And after 200,000 km, it is advised to replace the external fine filter. This will not bankrupt the owner, and the cost of repairs is also within reason.

Solenoids, contacts and wires fail. During repairs, gaskets, seals and clutches are replaced. Official dealers of AvtoVAZ do not repair automatic transmissions: they replace them as a whole. The cost is around 100,000 rubles. Weight – 33 kg. Removal and installation - within 10,000 rubles.

It is much cheaper to repair, and many car repair shops provide this service.

The Lada Granta automatic model shows characteristics that make it possible to classify it as an achievement of the domestic automobile industry. The Lada Granta Station wagon in the luxury configuration is also equipped with an automatic transmission.

Characteristics of automatic transmission

The idea of ​​installing an automatic transmission on the Lada came to AvtoVAZ back in 2010, but was realized only in 2011. A long-term contract was signed with the Japanese company Jatco, which is famous for the quality of its variators and hydraulics.

The box is not the best in terms of technical parameters, but it has been tested on other models for several years. We can safely say that all weak points are known, as well as ways to eliminate them.

From 2006 to 2010, Jatco was installed on Nissan Note cars. Numerous reviews from owners are positive based on the results of operating the unit.

Installation of the machine was difficult, since specialists needed to make more than 30 settings and adjustments. Rumor has it that craftsmen from Austria took part in the calibration process.

The box has very good ergonomics. The handle (link) is of optimal height, fits comfortably in the hand. The selective part is equipped with icons for visualization. The mode is duplicated directly on the dashboard.

At the same time, the locking of the lever in one position is uncertain. There are several operating modes of the machine:

You can “forget” about switching to third gear if the oil has not warmed up above 15°C. The fourth is activated at 60°C.

It is important to know. The design of the power plant does not have a flywheel, instead it is a drive disk.

Due to the transmission housing, the ground clearance was reduced by 1.5 cm. The automatic transmission control unit is located on the left front side, behind the optics. Many car owners express dissatisfaction about this, since in the event of a head-on collision, the risk of damage to the module is 100%.

The automatic operating modes are configured for driving in the city, on highways, in the countryside; to a lesser extent, the box is adaptive for driving on country roads. The noise level is minimal.

Scheme of work

The clutch assembly is located between the power unit and the transmission. When you press the clutch pedal, the connection between the engine and the wheels is broken. At this moment, the driver activates the desired gear to continue driving.

“Mechanics” is a metal case, inside of which there are shafts and gears. One gear is rotated by a motor, the other transmits rotational motion to the wheels.

Gear shifting occurs using a lever (slide), which is located inside the car.

Note to the driver! First and reverse gears have the most power but the lowest speed.

In a manual transmission, the gear travel is significantly reduced compared to the traction mechanism. The location of the switching block (module) makes it possible to minimize the dependence of the transmission on the ambient temperature and the operating temperature of the engine.

In the 2181 series box, it was possible to significantly increase the service life by reducing possible oil leakage points. Two sealing glands instead of the previous four.

Advice from experienced car owners and mechanics

Reviews of the Jatko automatic machine from most car owners are positive. For novice car enthusiasts, experienced drivers and repair specialists advise the following:

1. When wiping the internal blocks of the automatic transmission, use lint-free cloths. It is also recommended to wipe the dipstick with a clean, thick, smooth cloth. Since fluff can get stuck in the throttle holes and damage the electronic control systems of the machine.
2. When removing the oil filter cover, mark each bolt and its location with a felt-tip pen to avoid confusion. Because the bolts are of different lengths.
3. It is not recommended to use an automatic transmission with a low oil level or, conversely, with a high one.

What are the differences between a robot and an automatic machine?

Firstly, a robot is simpler, and therefore cheaper, than an automatic machine. At the same time, models with AMT consume almost the same amount of fuel as manual transmissions. However, the robot is not able to change speeds without losing power, whereas the automatic machine does this without losing traction.

As for the advantages and disadvantages of both ATM and automatic transmission, they are summarized in the table below:

Mechanical oil change

Changing the oil on manual transmission 2181 is carried out according to the instructions below.

• Unscrew the drain plug.

• Drain the oil into a container.
• Screw in the drain plug.
• Fill with fresh oil through the inspection hole.

Changing the oil on manual transmission 2190 differs from 2181. It is performed according to the algorithm below.

• Unscrew the drain plug.
• Drain the oil.
• Open the hood.
• Remove the air filter.
• Clean any dirt around the filler hole.
• Unscrew the dipstick.
• Add oil.
• Check the lubricant level.
• Reinstall the air filter.

The filling volumes of manual transmissions 2190 and 2181 are different.

Mechanical transmission firmware

New type firmware

LADAGRANTA/DATSUN 1.6L 8V, manual transmission

Transmission firmware is a rather complicated process; we do not recommend doing it at home. In order to comply with the requirements of the regulations, we advise you to use the services of certified workshops, where they provide a quality guarantee for the work performed.

The cost of services is negotiated individually in each case.

Jatco box design

The design of the Jatco automatic transmission, like other transmissions, consists of:

• torque converter;
• planetary part;
• valve body

Torque converter

The torque converter is both the clutch and the fluid coupling of the Jatco box. It converts torque from the engine and transmits it to the input shaft.

Planetary gear

Planetary gear includes:

Review, repair and maintenance of automatic transmission 01M

• sun gear;
• satellites that are attached to the planetary carrier;
• clutch;
• band brake.

Clutches and steel discs

The automatic transmission's clutches and steel discs serve as elements for engaging the clutch and transmitting torque. Essentially, friction clutches are steel discs, only friction tape is glued onto them. Pressing against the steel discs, the clutches connect the two rotating shafts of the automatic transmission.

All this is controlled by a computer, and the hydraulic unit presses on the pistons of the drums, squeezing the clutches in shifts.

Hydraulic unit

The automatic transmission valve body of the 414 e model is reliable and rarely fails. Most often, the owner has to replace solenoids. They are a consumable element of the transmission.

Characteristics and differences of JATCO automatic transmission

After the merger between Nissan and Renault, the latter began to be equipped with Jatco transmissions. This once again confirms the high quality and reliability of the units.

Jatco gearboxes are installed on both budget cars and middle-class models. For example:

The main difference between a gearbox is its simplicity of design, maintenance, and reliability. Automatic gearboxes and stepless variators (Tiptronic) are widely represented on the domestic market.

The machine is based on a complex control system at the level of solenoids and valve body.

For the first time since 2011, Zhatko boxes are equipped with solenoids made of a special material that is unpretentious to the quality of the transmission fluid.

This made it possible to change the oil less frequently, increase the service life of the fluid, and save some money. Maintenance of the unit is carried out every 75-85 thousand km. At the specified interval, it is necessary to replace the cleaning elements.

Automatic transmission diagnostic methods

To calculate the transmission problem, it is necessary to conduct computer diagnostics. Since this model of gearbox most often does not remember errors that occurred in it while using the car.

Service station specialists often use a trick to avoid having to go around with the owner looking for troubleshooting. They drive it onto the lift so that the wheels hang freely in the air and start the engine. And then they start looking for problems.

Electronic control system

The electronic control system rarely fails. If the firmware fails, then the technicians reflash the computer unit of the automatic transmission.

Mechanical and hydraulic part

The check occurs visually:

• If, when checking the oil, the owner found many black specks, this means that the friction linings have become unusable. Therefore, the sooner the car is sent to a service station, the lower the chance of a complete automatic transmission replacement.
• A jammed pan cover can damage the transmission's mechanical parts and cause oil loss.
• reading codes that appear on the dashboard. The explanation of fault codes is in the manual for this transmission model.
