VAZ-2106 is a rear-wheel drive sedan of Soviet and Russian production, produced from 1976 to 2006. According to the Russian specification, this model was in the third group of the small class, and was also considered an updated version of the VAZ-2103 model. The car platform was borrowed from the VAZ-2101 with minor modifications. The car was produced in Russia and Ukraine. The four-door sedan was equipped with gasoline engines of 1.3, 1.5 and 1.6 liters (64-75 hp). Transmissions: four- or five-speed manual. Various modifications were built on the basis of 2106, including right-hand drive 21064 and 21066 for delivery to other countries. The total production volume of all 2016 variants exceeded 4.3 million units, which made the “six” one of the most popular domestic cars.
Instructions for changing and topping up oil in the gearbox of a VAZ-2106 car
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.

- What kind of oil to pour into the box of a VAZ 2106
What kind of oil is poured into a box on a VAZ 2101-VAZ 2107?
Welcome! What still needs to be filled with oil in the gearbox on the “Classic”? And how much oil comes into the box? These questions are asked to us very often, but not all people usually know the answer to them, and therefore, especially for such people, we will look at these questions in detail in the article.
What kind of oil should be poured into the box?
If we talk about cars of the “Classic” family with a 4-speed and 5-speed gearbox, then only special gear oil is poured there, which will lubricate all the gears that are in the boxes during their operation.
From the above, we understand that only transmission oil is poured into the box, and what viscosity grade does this oil make and what group should it be, you ask? For classics, the oil group should be either “GL-4” or “GL-5”. The viscosity grade must be designated “SAE75W90”, or “SAE75W85”, or “SAE80W85”.
What do all these symbols mean and where are they located?
These symbols are usually written on the boxes in which the oil is located, and they indicate the viscosity class of the oil and the group to which the oil belongs, we will analyze it in more detail:
GL-4. these oils contain a large number of additives. In general, this type is only used on vehicles with gearboxes that operate at high speeds but with little torque, and in low speed but high torque applications.

GL-5. These oils are intended for use in Hypoid gears. these are gears where two gears rotate at an angle, like looking at the photo a little lower.” At the moment, the hypoid gear is only in the gearbox on the classic, and, as you already understand, the gearbox needs to be filled with GL-5 oils. But this group of oils has also found its application in the box, but mainly this group is used only for the box, which constantly operates under difficult operating conditions.
SAE75W90. this is a measure of the viscosity of the oil itself, and this abbreviation means that the oil is semi-synthetic or simply synthetic, this oil is still commonly called all-weather oil, because if you look at the numbers at which the oil either freezes or boils, then these numbers go beyond 35 and 40, therefore such oil can be used on cars that are used in Russia, because such a climate is considered almost the norm for our country.
SAE75W85. this viscosity grade is also used for so-called all-season oils, and the temperature at which the oil hardens is beyond .40 and should not exceed 45, otherwise the oil may boil.
SAE80W85. and the viscosity of the oil of the latest type is 80W-85, which boils at above 35 degrees and does not freeze up to 30 degrees.
How much does oil cost in a box on a classic?
Many people are used to asking this question in this form, but in fact it is an incorrectly posed question because the oil is in such a box, and therefore it would be correct to ask your question in this way: “And how much gear oil will go into the box case?
It's not really that important, but it's still the same, so let's get closer to answering the question and it would be: If the car has a 4-speed box, then it will only take 1.35 liters of gear oil , and if the box is 5-speed, then all 1.6 liters!
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.
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.
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 kind of oil should I fill in?
Original
The VAZ-2106 manual transmission requires TAD-17I mineral oil with SAE 80W-85 API GL-4 specifications. Mostly in winter you can use oil with a viscosity of SAE 70W, 75W, 80W or 85W, and in summer SAE 90, 140 or 250 is recommended. In this case, the most popular is all-season oil with a viscosity of SAE 75W-80, 80W-85, 85W-90, 75W- 90 or 80W-90. It is suitable for year-round use.
Unoriginal
Owners of a VAZ-2106 with a manual transmission can use any gear oil with 80W-85 characteristics. For cars of recent years, you can choose semi-synthetic, and for older cars - mineral oil. It has a thicker consistency, which means there is less chance of leaks in the presence of microcracks or gaps between contact pairs. Among other parameters, it is important to pay attention to oil with API-GL-4 approval, which contains enough useful additives for a manual transmission. For example, a suitable analogue would be TNK Trans KR 75W-90.
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.
What tool will you need?
Advice. It is best to change the oil in an inspection pit or on an overpass. It just won’t be pleasant when hot oil pours on you lying under the car!
Tools
You will need:
- 17-size open-end or socket wrench
(if the filler plug sticks, you can use a head with a knob, if convenient), - a 12mm hexagon
(for unscrewing the drain plug) and a tube
to it, so that there is more leverage, - oil container
. It is enough to take a container of 2 liters, since the oil in the gearbox should be 1.6-1.7 liters (5 tbsp), but in fact there is usually less of it. - syringe for filling oil
. If you have a special syringe with a curved tube at the end, that’s just fine, - if there is none, then you can use a regular syringe with a longer hose attached to it,
- Well, if this is not possible, then you can take a long hose of a suitable diameter, lead it into the engine compartment and pour oil through a watering can.
Note: with this method, the oil must flow well (have a sufficient temperature), otherwise it simply will not reach its destination - the gearbox.
- oil for filling.
You will need 2 liter canisters of it - you will still have some left over for lubricating other parts.
Oil is filled with 80W-90 brand of any desired manufacturer
(or selected by price). Usually the price for oil is not high.
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, if necessary
- use a metal brush and 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.
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.
