The gearbox makes it possible to change the acceleration rate of the car, increase the speed at different speeds, rotate the wheels at different speeds, etc. During operation, the gearbox may fail, which will require repair of the gearbox on the VAZ 2114.

Checkpoint disassembled

The best way to prevent breakdowns is to take preventive measures. Unfortunately, even the most careful care is not able to protect the box from the occurrence of certain malfunctions.

Design features of the gearbox

On the Russian auto market, the VAZ 2114 (restyling of the VAZ 2109), which is equipped with a manual transmission, is very widespread. The peculiarity of this device is that it perfectly copes with the loads placed there.

From time to time the box on the VAZ 2114 needs to be serviced. The VAZ gearbox includes the following main elements:

crankcase;
back cover;
gear links/numbers;
differential;
shafts;
gears.

Manual transmission is divided into the following types:

4-speed;
5-speed;
6-speed.

Each of these types of boxes has different supports, and drain plugs are installed in different compartments.

Selecting gearbox oil

From time to time it is worth keeping the oil level under control; it is recommended to top it up as needed. A complete oil change will be required when the car has crossed the 60,000 km threshold.

It should be noted that early wear of mechanical components on the VAZ 2114 occurs due to brutal driving or abrupt shifting of the gear lever.

The gearbox for this version of the car works perfectly with GL-4 class mineral oil. It helps to extend the working life of the box. Options needed: 75W90, 80w85, 85w90. When always selecting lubricants for the gearbox, you need to take into account the conditions under which the car will be operated, and pay attention to the viscosity of the transmission oil.

Extending the service life of gearboxes

You will be able to use your car for many years without going to car repair shops if you can follow basic recommendations. They will extend the service life of the gearbox, minimize possible problems, breakdowns and the need for repair work.

Transmission shaft assemblies

There are only two recommendations.

Always try to monitor the oil level in the gearbox. If it drops, be sure to top it up immediately, do not delay the procedure until later. When the oil becomes unusable, change it completely, rather than fill in the missing amount.
Avoid aggressive use, do not jerk the gears sharply, accelerate smoothly, and brake similarly. A simple caring attitude towards the gearbox will allow you to avoid wear and tear and numerous breakdowns.

As you can see, solving problems with checkpoints is not so easy. Therefore, the best option is to prevent their occurrence.

The need for repair and restoration work

The VAZ 2114 gearbox is subject to repair. Typically, this procedure includes installing new gears and bearings. Repair of the VAZ 2114 gearbox is advisable if the following manifestations begin to be observed:

stiffness when performing manual gear changes
;
a knocking sound occurs when changing gears or in a certain gear;
if the synchronizer breaks down, a corresponding crunch may occur;
if lubricants have lost their characteristics, then this causes an increasing rumble (usually in neutral).

In case of any of these manifestations, it is recommended to contact a service center for diagnostics of the entire auto accounting system.

The main stages of removing the box

How to remove the gearbox on a VAZ 2114? To begin dismantling the box yourself, the driver must arm himself with screwdrivers, spanners, and WD-40 liquid. Stages of dismantling the box:

A VAZ can be placed on an overpass.
You need to disconnect the battery and remove it.
The oil is drained from the box.
Dismantling the starter, protective jacket, connecting cable.
The wiring present on the speed control sensor, reverse sensor is disconnected.
It is necessary to remove the jet thrust fixed on the bolts.
Removing the wheel drive.

The process of dismantling the box takes about 5 hours. Assembly proceeds in reverse order.

VAZ 2115 | Gear shift

Gear shift and lever position

The gear shift positions are shown on the handle. Before engaging reverse gear, you need to lift the ring under the lever handle.

When changing gears, fully depress the clutch pedal and then gently release it. It is not recommended to drive a car with one hand on the gearshift lever, as this increases wear on the gearbox.

When shifting from fifth to fourth gear, do not press the lever laterally, so as not to accidentally engage second gear, which will cause the engine to exceed the permissible speed and damage it.

Before engaging reverse gear, make sure that the car is at rest and your foot is not on the gas pedal. Move the lever from the neutral position to the right until it stops, and then engage the rear

move.

The table below shows the driving speeds at which the next gear should be engaged for the greatest fuel economy.

The reverse gear of the VAZ 2114 does not engage well

Many transmission malfunctions that cause the reverse gear to disappear or fall out can be eliminated without removing the unit from the car.
If the cause is a loosening of the bolt securing the clamp on the rod, then to correct the defect it is necessary:

Place the car on a lift.
Completely loosen the clamp nut.
Place the gearshift lever in the fully engaged reverse gear position.
Fully engage reverse gear at the gearbox using the shift rod on the crankcase.
Tighten the clamp mounting bolt.

Backstage adjustment

If tightening the clamp does not help get rid of the problem, then you need to check the condition of the shift drive parts. One of the reasons why the reverse gear does not engage may be a poorly adjusted rocker.

To make adjustments to the mechanism, you may need the following tools:

two wrenches with a size of 13 mm, preferably a socket design;
any wrench or 10 mm socket;
small hammer;
slotted screwdriver.

Since the cause of malfunction of the link can be wear of parts, spare parts may be needed:

universal joint of the rocker;
Sometimes the shift rod seal may need to be replaced.

Two people are required to adjust the rocker or replace parts of its drive. One person must change gears from the passenger compartment, and the second must adjust the travel of the shift rods.

The order of work is as follows:

Provide access to the bottom of the car by placing it on a pit or a lift.
Using a 13 mm wrench, loosen the clamp installed on the gear shift rod.
Remove the rod from the box rod.
Using a screwdriver, carefully remove the boot.
Using a 10 mm wrench, unscrew the fixing bolt on the cardan shaft.
Knock off the cardan shaft with light blows of a hammer. It is important not to damage the shaft.
Remove the universal joint seal boot.
If there is an oil leak, the sealing gland on the box rod must be replaced.
Install a new boot (or leave the old one if it is intact) and install the universal joint on the shaft.
Align the hole on the cardan with the notch on the shaft.
Tighten the 10 mm clamp and install the boot completely in place.
Install the rod on the cardan rod and adjust the gearshift lever travel.
The second person should sit in the driver's seat, set the gear shift lever to neutral, move it slightly to the right and hold it in that position.
After this, you need to tighten the 13 mm clamp nut.

Typically, after such a repair, the reverse gear starts to engage without problems. In addition, the operation of the entire gear selection mechanism on the VAZ-2109 becomes clearer.

The video from the author MegaMeyhem shows the process of replacing the backstage.

Changing the gearbox oil

If the oil seal on the rod is damaged, oil leaks out of the gearbox housing, and dirt can get into the box itself. These factors may be the reason why reverse gear stops engaging. In addition, the oil in the box loses its properties during operation, so it must be replaced preventively at least once every 35–40 thousand kilometers.

Before replacing, you need to check the condition of the oil in the box. To do this, you need to remove the oil dipstick installed in the gearbox housing and visually assess the quality of the oil. The presence of metal and dirt particles in the oil on the dipstick is unacceptable. The oil itself should be quite liquid and not stick to your hands in a thick layer.

Dipstick with oil level marks

To replace, you will need the following materials and tools:

New oil. When purchasing oil, you need to consider the type of gearbox. For fairly rare four-speed gearboxes, three liters of oil are required, for newer five-speed ones - 3.3 liters. The oil itself must have a tolerance of 80W-85, the manufacturer does not matter.
A container for draining old oil with a volume of at least 4 liters.
A funnel with a hose for pouring new oil or a syringe.
Wrenches 12 and 17 mm of any type.
Rags and cleaning solvent.

The actual work order is as follows:

Place the car with the heated gearbox on the pit.
Remove the rubber plug from the gearbox ventilation valve installed on the top of the crankcase.
Clean the valve and plug from dust and dirt. It is convenient to clean parts with thin wire and a rag.
Reinstall clean parts.
Wipe off dirt from the bottom of the box. Unscrew the plug on the bottom of the box housing.
Place a container under the drain hole and drain the oil. It will completely merge in at least 20-25 minutes.
After this, screw the drain plug back into place and carefully tighten it with a wrench. First, the plug and hole must be thoroughly wiped with a rag.
Pour fresh oil through the oil level dipstick hole in the box.
During filling, it is necessary to check the oil level, which normally should be between o and “MAX” on the dipstick rod.
If there is an overflow, the oil can be pumped out with a large medical syringe with a tube on the spout.
Within a few days after the change, it is advisable to check the level and appearance of the oil. You also need to make sure that there are no leaks through the plug and box seals.

On early versions of front-wheel drive VAZ gearboxes there is no hole for the dipstick. To fill the oil in the crankcase of such boxes there is a control hole closed with a threaded plug. Filling is carried out using an oil syringe. The oil level is considered normal when it reaches the lower edge of the inspection hole.

Repair or replacement

If, during checking the condition of the box, serious damage to its elements was revealed, then serious repairs cannot be avoided.

It should be immediately noted that independent dismantling, repair and reassembly of a gearbox requires not only very good equipment (nominally a pit or overpass, a lifting device, as well as a large set of tools are required), but also very serious knowledge.

That is why, if the gears of a VAZ 2114 do not engage, such repairs should be entrusted to specialists from car service centers.

It should be remembered that independent repair or replacement of the gearbox automatically leads to the loss of all warranty obligations from the manufacturer. For this reason, repairs to a car that is under warranty should be entrusted to branded repair shops.

If we talk about the choice between repair and complete replacement of the unit, then in most cases you should choose the first option. This is due to two reasons. Firstly, the cost of a completely new box exceeds 15 thousand rubles. (moreover, this amount is indicated without taking into account the cost of its installation). In any case, repairs will be much cheaper. And secondly, complete wear of the box (to a state unsuitable for repair) is extremely rare.

The cost of the repair work itself varies from service to service and depends on:

the size of the locality (and, as a consequence, the presence of competitors);
type of breakdown;
the size of the car service (and whether it is official);
additional clauses in the terms of the contract.

Why is reverse gear difficult to engage?

Regardless of what type of transmission is installed on the car (automatic or manual), poor engagement can be encountered at any gearbox. In such a situation, it is necessary to identify the breakdown and make repairs, since it is impossible to drive a car without reverse gear. Let's look at each reason in more detail.

Wear of the rocker bushing

Sometimes turning on reverse gear is accompanied by a lot of vibration and a characteristic crunch. The gear knob moves hard. In this case, the adjustment of the link, which connects the rod and the gear shift lever, may be disrupted. In addition, plastic bushings wear out quickly and must be replaced on time.

An experienced driver may notice excessive looseness and play in the lever. But if the wear occurs gradually, then it is difficult to notice the increasing free play. All repair work can be done directly from the salon. It is enough to remove the gear knob cover, remove the rocker and replace the bushing. After adjustment, the inclusions become clearer and softer.

The durability of a plastic part depends on the quality of the material used by the manufacturer. After adjusting the stroke of the rocker and replacing the bushing, this problem disappears. Sometimes craftsmen replace the factory mechanism with a shortened stroke. But they often forget that for it to work properly, it needs to be more accurately configured.

Electronics faults

Vehicles are equipped with different gearbox locking devices. Some vehicles use electromagnetic locking. In this case, the electrical wiring is located under the bottom of the car and is not protected by anything. In off-road conditions, the wires must be protected from damage, otherwise they will quickly become unusable. As a result, the supply of electricity to the interlock will stop and a problem will occur related to gear shifting.

Transmission traction is broken

Some cars are equipped with transmissions in which the shift rods are located outside the mechanism housing. In difficult climatic conditions (dirt, snow, icing), the free movement of traction is disrupted. This is especially noticeable when switching reverse gear, since it is rarely used. But in the morning it is necessary to leave the garage. To avoid such problems, in difficult conditions it is recommended to use a car that does not have external gear shift rods.

Note! Sometimes the length of the rod changes due to the loosening of the adjusting nuts, making shifting difficult. In this case, you will need to adjust and adjust the length, and the issue will be resolved.

There is not enough oil in the gearbox or its properties are reduced

If you do not take care of your car, a problem with engaging reverse gear may occur due to insufficient oil in the box or a deterioration in its performance properties. Inexperienced drivers believe that oil is poured into the gearbox all the time, and there is no need to change it. In reality, even high-quality lubricant with high mileage (about 100 thousand km) becomes unsuitable for use. These data correspond to a gentle driving mode.

Replacement box - new or old?

If the reason why the gears on the VAZ 2114 are poorly engaged is due to very severe wear of the gearbox components, and it turns out that its repair will be more expensive than a complete replacement, then the motorist is faced with a choice - install a new gearbox or give preference to a “restored” one.

The first option is certainly preferable, but the fact is that a new gearbox is not cheap at all (as mentioned above).

The cost of a refurbished one is much less (sometimes such a box costs 70% less than a new one).

A rebuilt gearbox is an excellent option, which is almost in no way inferior in quality to a new gearbox, but at the same time costs much less. The only thing to remember is that such units should only be purchased from trusted companies that professionally restore them and provide a guarantee for their products.

It should also be remembered that if there is a choice, it is better to give preference to the “middle option”. You should absolutely not purchase refurbished boxes from little-known companies at a very low price.

Types of checkpoints

Manual transmission

Today, all cars are equipped with one of three types of gearboxes.

Mechanical. Speed shifting is done manually using a special lever.
Automatic. No external influence is required to change gears. Switching is carried out depending on the degree of pressure on the brake and gas pedals. In this case, reverse gear is engaged manually.
CVTs. This is a mixed type of gearbox, where the bulk of the work is performed automatically, but if necessary, the gearbox is switched to manual mode.

Advice for motorists

Above we have already talked about why the reverse gear on the VAZ 2114 does not engage and how to correct this situation. But it should also be noted that proper and timely care of the gearbox will help either completely avoid such a situation or postpone it for as long as possible.

There are only two basic rules for this care:

Change gears, as well as accelerate and brake the vehicle as smoothly as possible, without jerking.
Periodically check the oil level, replenish it as it is used, and also replace the entire volume if it is worn out.

These simple rules will help to significantly increase the service life of the entire box and its individual parts.

Box nuances

The VAZ 2114 uses a five-speed manual gearbox. It is quite simple in design, which allows you to independently carry out preventive and repair work.
