Manual transmission parts are not exposed to high friction or extreme temperatures. For this reason, some motorists ignore this unit without paying due attention to it. Some people forget to change the oil, others periodically top up their light engine for easy gear shifting in winter, and still others use protective additives. And only the third type of motorist has truly adequate gear shifting, there is no crunching or squeaking in the gearbox, and the entire internal structure of the car works like a clock. Of all the variety, one can highlight the Liqui Moly Getriebeoil-Additiv additive for manual transmissions.
Description of the additive in manual transmission
Liquid Moly art.
3967 (0.02 l) Liqui Moly Getriebeoil-Additiv is a specialized additive to transmission lubricant with an anti-friction effect. The main active ingredient of the product is molybdenum disulfide (MoS2). It effectively reduces friction and extends the service life of the unit. Also, other active components are added to the additive composition, which improve the quality and performance characteristics of the lubricant. The Liqui Moly additive for manual transmissions with molybdenum ensures smoother and quieter gear shifting and reduces the heating of the gearbox during operation.

Peculiarities
Gearbox additives from the Kharkov company XADO have proven themselves in the antifriction gel market. The company itself positions its products as “revitalizants”, focusing on the fact that they can restore the original shape of gearbox parts . This is how XADO additives differ from products from other manufacturers, which only reduce friction between parts.
The operating principle of XADO gels is based on a metal-ceramic coating of parts. A special chemical formula allows you to fill microcracks and smooth out roughness. Even if the car is in long-term operation and the contacting parts in the gearbox have lost their shape, the XADO additive allows you to restore their correct geometry and avoid costly replacement of gears or bearings.
Restoring parts, according to the manufacturer, helps to significantly reduce noise and vibration when driving. This also allows you to make the consumption of fuel and lubricants more economical.

User reviews
Gels from XADO are ideal for restoring heavily worn cars. This manufacturer appeared on the market relatively recently, but has now become quite famous thanks to its unique technology based on metal-ceramics. With the help of XADO additives, some car owners even managed to restore the performance of old Soviet cars. True, for this it was necessary to increase the recommended norm.
However, this manufacturer also has negative reviews. The fact is that XADO additives form a hard ceramic coating on the engine, which is practically impossible to process. That is why the products of this company are more often used to reanimate old cars, rather than to work with relatively new models.

Automatic transmissions
Every motorist wants to know which automatic transmission additives are the best and what is best to put in automatic gearboxes. But objectively, the best additive for automatic transmissions cannot exist alone. These are at least several solutions that interact perfectly with the machine. Therefore, the choice of additive to be poured into an automatic transmission should be approached carefully in order to buy and fill in the additive that is not just well advertised on TV or on the Internet. Often, buyers are fooled by marketing decisions, which is why they overpay for a brand without receiving real benefits. If you are really interested in the best additive for automatic transmissions, then you should pay attention to several current leaders in the segment.
RVS Master
RVS for automatic transmissions are made on the basis of magnesium silicate salts and auxiliary components. They allow you to create a protective and wear-resistant film on the surface of parts. Using such means, you can restore the geometry of automatic transmission components, stabilize the operation of all components and extend their service life. The additive helps eliminate noise and vibration, reduces the intervals between gear shifts in automatic transmissions. Studies have shown that RVS effectively resists the phenomenon of slipping if it is caused by malfunctions in the automatic transmission.
Liqui Moly
It will not surprise anyone if the best additive turns out to be the result of the work of Liqui Moly. Their automatic transmission solutions can protect and restore friction surfaces. Special compositions restore the elasticity of the seals and prevent lubricant leaks in the automatic transmission. By using additives from this company, designed specifically for automatic transmissions, you will extend the life of the automatic transmission and be able to preserve the original properties of the transmission oil.

Reviews
Kim, 23 years old Liqui Moly 1988 has become a lifesaver. The transmission crunched horribly, especially in second gear. There was no time to get to the service center; I bought an additive at a gas station. Now there is no need to go to the service center: literally the next day the crunching noise disappeared.
Oleg, 36 years old When changing the oil in the box, I added this product to my old Kia. There were no special problems, but I played it safe. They say you can really extend the life of the mechanics.
Additives for manual transmission: how to choose and use correctly
The use of additives will have a positive effect if they are compatible with the gear oil.
For additives to give the best results, they should be added a couple of days after changing the oil.
Before using the additive, it is necessary to warm up the gearbox to normal operating temperature. Then turn off the engine and fill the mixture through the specially provided hole. Next, it is recommended to drive the car 15-20 kilometers in different gears.
After these manipulations, you can use the car as usual.
To choose the right additives, you need to read the description of each and compare it with your goals, car model and type of gear oil.
Recommendations for the use of additives for manual transmissions
The price of an additive is not always an indicator of its quality. It is necessary to carefully study the description of the material and real reviews about it.
Some additives promise to prevent transmission oil from aging and dramatically extend the period between oil changes. However, the reality is that you should change your oil on a regular schedule, regardless of the additives used. When the vehicle operates in difficult conditions, it is advisable to reduce the interval between replacements.
Rice. 2. Replacing gearbox consumables
It is not recommended to frequently use sealing additives, as they create a sealing layer not only at the site of the leak, but also on all elements of the gearbox. A coating forms on the internal elements of the box, which can only be removed by disassembling the mechanism. In addition, such additives can only temporarily eliminate a leak, and not eliminate it. If you do not take any additional measures to eliminate it, it will grow over time and will definitely not be possible without repairs. Therefore, they are more suitable for unscheduled use than for permanent use.
It is important to strictly adhere to the dosage of additives recommended by the manufacturer. You should not experiment with the amount of material, hoping to enhance its properties.
Do not add additives to oil whose life is more than 70-80 percent used.
Some additives may not immediately give a positive effect, but only after a certain number of kilometers.
Next, we present a list of effective additives according to car enthusiasts and their main characteristics.
