Having first appeared in 1975, the VAZ “six” turned out to be a long-liver, and with figures close to record ones: it was produced until 2005, that is, 30 years, and during this time about 4 million copies rolled off the assembly line. It is safe to say that this model is one of the most popular models in the global automotive industry.
It is not surprising that today the VAZ-2106, along with all its modifications, is a frequently encountered car on the roads of post-Soviet countries. Relatively low cost, availability of spare parts and ease of operation, maintenance and repair are the main advantages of this model. Most car repair and maintenance operations can be done on your own, including changing the oil in the VAZ-2106 gearbox.
We will tell you about it today.
How often to change transmission oil
According to the manufacturer’s recommendations, the frequency of oil changes in a “six” manual transmission is every 75 thousand kilometers. Such an impressive interval is quite understandable - transmission oil does not work under such extreme conditions as engine oil, so this indicator can be considered optimal. However, when operating a car in difficult conditions, the frequency recommended by AvtoVAZ may not be enough - many Six car owners perform this operation after a mileage of 60 thousand km.
What and when to pour into the VAZ-2110 gearbox?
The box, which is used in the domestic “ten”, is quite durable and hardy. But this is only subject to proper operation and timely replacement of transmission oil. The most suitable for the VAZ-2110 gearbox can be considered a synthetic base. This is especially true for cars that are operated in extreme conditions. True, synthetics have one drawback, which is their high cost. But, given the replacement interval, you can spend money. As a last resort, it is permissible to use semi-synthetic oils. But you can’t mix synthetics and semi-synthetics. You shouldn't forget about this.
If we talk about which gear oil is best for the VAZ-2110, then the first thing you need to decide on is the viscosity. There are summer, winter and all-season transmission oils. The latter are the most popular due to their versatility. True, the price tag for such a lubricant is a little higher, but it’s worth it. The manufacturer recommends TM-14-2 oil, which is what needs to be poured into the box. There are better analogues, such as Lukoil-Super. True, the base here is mineral, so it is not suitable for gears, but it supports the operation of synchronizers perfectly. Valvoline SynPower is a Dutch synthetic oil. It is expensive, but the performance characteristics are at the highest level.
Recommendations for choosing oil
Any oil with viscosity values 75W90, 75W85, 80W85, 80W90, 85W90 is suitable for filling into a mechanical five- or four-speed VAZ gearbox. Questions arise when it is necessary to solve the dilemma of which oil is better to fill in the VAZ-2106 gearbox: mineral water, semi-synthetic or synthetic.
An important and at the same time practically the only advantage of mineral water is its low cost, which is one and a half to two times lower than synthetics or semi-synthetics. This is due to the composition of such a lubricating fluid, which does not contain any additives. At the same time, the lubricating properties of mineral oil are quite decent, allowing you to operate a car without changing the oil for 60 - 75 thousand kilometers. A significant disadvantage of mineral water is a decrease in viscosity in severe frost, which makes it difficult to change gears on a cold engine.
The only drawback of semi-synthetic and synthetic gear oils is their high cost. But they have more than enough advantages: excellent manufacturability, the presence of wear-reducing additives for gearbox parts, and the possibility of trouble-free operation in a wide temperature range.
Total Transmission Dual 9 FE 75W90
Among some car enthusiasts, there is an opinion that the use of synthetic oil in the VAZ-2106 gearbox contributes to squeezing out the oil seals, which leads to their leakage. In reality, such problems have nothing to do with the type of transmission fluid used; their cause lies in the wear of parts and components of the gearbox.
What do motorists advise?
Experienced owners of the “six” assure that you don’t have to get hung up on the list above and use gear oil from absolutely any manufacturer for the VAZ 2106 gearbox, the main thing is that its viscosity is 80W-90 or 85W-90. Whether you take their word for it or not is up to you.

Tools and accessories
To change the oil in the “six” yourself, you will need the following tools and materials:
- wrench 17 (if the fasteners do not give in, an extension wrench may be required);
- a 12mm hex wrench, preferably also with a long tube, to increase the leverage of the applied force;
- waste container with a volume of 2 liters;
- a special syringe characterized by a curved end (a regular medical syringe is also suitable; instead of a needle, a hose about 25 centimeters long is attached to it);
- rags.
To change the oil, it is advisable to place the car in a pit or overpass; to top up the transmission fluid, this is not necessary.

How to check the oil level in a box with topping up
It is recommended to check the transmission oil level in the VAZ-2106 gearbox on a cold car. If the procedure is carried out immediately after a trip, you must wait at least 10 minutes (depending on the time of year and ambient temperature) for the oil to drain from the gearbox parts into the crankcase.
The level is checked not using a dipstick, as on an engine - it is filled to the upper edge of the filler hole located on the side plane of the gearbox.
The algorithm for checking and topping up the oil level in the gearbox is extremely simple:
- unscrew the oil filler plug, clean it of dirt, use a metal brush if necessary, wipe it dry;
- checking the oil level - visual: if there is more than needed, it will flow out of the hole, if less, it needs to be added using a syringe;
- screw the oil filler plug into place;
- Wipe away transmission fluid leaks with a rag.
About viscosity grade
If we talk about models such as VAZ-2106, 2107, then for these cars they most often choose a lubricant with a viscosity of 75w90. This is a synthetic or semi-synthetic base. This gear oil is excellent for use in harsh weather conditions. The temperature range at which this lubricant can be used is from -40 to +35 degrees Celsius.
In addition, oils with viscosity 75w85 and 80w85 are widely used. These are all-season lubricants that are also excellent for use in low temperatures. It is worth noting that the manufacturer recommends using these viscosity grades. In general, oils such as TNK or Lukoil of the corresponding group and class can be poured into domestic classics.
Complete oil change
Since checking the oil level is not required, it is advisable to change it when the car is warm. Sequencing:
- We install the car on a pit, overpass or blocks to gain access to the drain hole located on the bottom of the box housing.
- We place the prepared container under the drain hole.
- We unscrew the drain plug using a hex wrench, being extremely careful as the oil is hot.
- When the waste stops dripping, carefully clean the drain hole and seat from dirt, tighten the drain plug without being too enthusiastic (so as not to strip the thread).
- Using a socket or wrench 17, unscrew the filler plug located on the side wall of the box on the right along the direction of the car.
- Filling with fresh transmission oil is done using a special syringe with a curved end, although it is quite possible to use a regular large-volume syringe by attaching a rubber or plastic hose 15–25 cm long to its lower end using tape.
- Since the volume of a special syringe is 500 cm3, and it is also quite difficult to find a syringe of a larger volume in pharmacies, filling should be done several times, and quite slowly.
- When liquid begins to flow out of the filler hole through the top, this means that the required level has been reached.
- We tighten the plug, also without applying excessive force.
- We check for the presence or absence of leaks, first of all from the drain hole. If necessary, tighten the plug.
After completing the procedure, we check the used oil for the presence of metal shavings, crumbs and microparticles. If any, this indicates the need for transmission repair. We visually inspect the housing for cracks and leaks; if they are present, it is necessary to eliminate the detected defects.
If the waste is black in color, indicating that it is heavily contaminated, it is advisable to flush the gearbox housing before changing the oil in a manual transmission in a VAZ model 2106. For this procedure, you will need to mix 0.7 liters of transmission fluid and 0.3 liters of diesel fuel (you can use a ready-made flushing mixture sold in auto chemical departments). We pour the resulting liquid into the box, jack up one of the drive wheels, start the engine, and let the engine run in one of the forward gears for several minutes. Drain the flushing fluid and fill in new one.
Regularly checking the oil level and quality will help determine whether it needs to be replaced ahead of schedule. If the transmission fluid becomes very dark, an unscheduled replacement should be carried out, which will help extend the life of the manual transmission.
How to change: main stages of the process
A successful replacement of the transmission substance in the box occurs after a trip over a distance of more than five km. This is necessary for the liquid to warm up. The transmission oil is changed by immobilizing the car on an overpass or inspection hole. Operations are created according to the following annotation:
