Reliable operation of the gearbox ensures comfortable operation of the vehicle. Emerging problems with the gearbox sometimes make driving a car impossible. Therefore, the gearbox is rightfully considered one of the most important components of a car.
The volume of oil poured into the VAZ 2107 gearbox depends on the modification of the unit. VAZ 2107 cars were equipped with four- and five-speed gearboxes. A specific type of vehicle configuration requires a different amount of the substance to be poured.
REASONS FOR REPLACING TRANSMISSION OIL IN THE VAZ 2107 Gearbox
The gearbox is a unit with a lot of rubbing parts. The frictional force particularly intensely affects the gear teeth in the box, so they become very hot. If the impact of the friction force is not reduced in time, the teeth will begin to collapse, and the service life of the box will be very short.
The five-speed gearbox of the VAZ 2107 is replete with rubbing parts that need lubrication
To reduce friction force, special gear oil is used. But it also has its own service life, after which the oil loses its properties and ceases to perform its functions. The only solution to this problem is to fill the box with a new portion of lubricant.
FREQUENCY OF CHANGING TRANSMISSION OIL
If you look at the operating instructions for the VAZ 2107 car, it says that the transmission oil should be changed every 60–70 thousand kilometers. The problem is that these figures are only valid when the operating conditions of the car are close to ideal, which is not the case in practice. Why? Here are the reasons:
- low quality gear oil. The reality is that the modern car enthusiast often has no idea what exactly he is pouring into the gearbox. It's no secret that fake gear oil is found all the time. Products of well-known brands are especially often counterfeited, and the quality of the counterfeits is often such that only a specialist can recognize them;
- low quality of roads in the country. When driving on bad roads, the load on the gearbox increases significantly. As a result, the lubricant life is developed faster. In addition, the driver’s driving style has a significant impact on the oil life. For some car enthusiasts it is softer, for others it is more aggressive.
Taking into account the above, it is recommended to change the transmission oil after 40–50 thousand kilometers, and it is advisable to buy lubricant only in specialized stores that are official dealers of the selected lubricant brand. This is the only way to minimize the likelihood of purchasing counterfeit gear oil.
About types of transmission oils
Modern industry offers a wide range of different fluids, and the quality of the gearbox depends on the correct choice. At the moment, there are three types of oils: synthetic, semi-synthetic and mineral water . Each of these mixtures has its own set of characteristics and properties.
Mineral transmission is the most budget option. This oil has good lubricating properties, but has a significant drawback. In extreme cold conditions it freezes very quickly .
Unlike mineral water, synthetics and semi-synthetics have a higher price. In addition, such oils thicken less at low temperatures and are excellent for use in severe frosts. Synthetic and semi-synthetic oils also differ from each other. The consistency of semi-synthetic liquid is thicker than synthetics. It is great for cars with high mileage. Synthetic oil is better used for new gearboxes, as it is thinner and can leak if there are even the smallest defects in the seals.
When choosing products, first of all, you need to pay attention to viscosity. SAE index indicates .
SAE standards, transmission fluids are divided into the following categories:
- Summer oil (marking consists of numbers only).
- Winter mixture (in its designation it has the English letter W - winter ).
- All-season liquid. The marking of such a lubricant consists of two numbers, which are separated by the letter W. This oil can be used all year round.
Synthetic and semi-synthetic oils that have the following viscosity classes are suitable for the gearbox:
- SAE80W85 is an all-season liquid with a temperature range from -35 °C to +35 °C.
- SAE75W90 is a mixture used at any time of the year with a recommended temperature range from -40 °C to +35 °C.
- SAE75W85 is a multi-season oil, designed for work within the range of -40 °C...+45 °C.
In addition, when choosing transmission fluid, you can come across the API . It implies the systematization of lubricants according to their quality, application and performance characteristics. There are 7 groups in total, but only two are the most popular.
the VAZ 2107 gearbox, the manufacturer recommends the following groups of transmission fluids:
- GL-4. This oil is characterized by the presence of a large number of additives. It is used for gearboxes that operate in high gears at low torques and in low gears at high torques.
- GL-5. This fluid was developed for hypoid gears with high axle displacement. It has proven itself well when working in harsh conditions.
CHECKING THE OIL LEVEL IN THE TRANSMISSION
To check the oil level in the gearbox, you need to do a number of simple steps.
- The car is installed on a viewing hole.
- The oil drain and fill holes on the gearbox are cleaned with a metal brush.
- Using a 17 wrench, unscrew the plug from the hole for adding oil.
The plug from the filler hole is unscrewed with a 17 wrench - The oil level should normally be 4 mm below the edge of the fill hole. The measurement is made using a probe or a regular screwdriver. If the oil goes below 4 mm from the edge of the hole, then it needs to be added to the box using a syringe.

Technical regulations on the amount of transmission substance
Transmission fluid is monitored every 10 thousand km, i.e. during the next maintenance. Before checking the amount of substance, you need to let the car sit for a while. During this period, the transmission fluid will have time to flow down the walls of the box. If the fluid level reaches the edge of the lower edge of the filler hole, then its volume is quite sufficient, and the oil is not replaced or topped up.
How much transmission oil will be needed when completely replacing it directly depends on the type of gearbox. According to the technical instructions, the following volume of liquid is established:
- for 4-mortar – 1.35 l;
- for a 5-mortar – 1.6 l.
Experienced drivers advise filling the 5-mortar with lubricant slightly above the set level - “as much as it will fit.” To do this, lift the car from the driver's door with a jack. Then add 250–300 g of liquid. This will ensure reliable lubrication of the 5th gear gear. There is no need to be especially afraid of increased pressure on the seals, since excess pressure is released through the breather.
Changing the oil in the gearbox and gearbox!
The mileage on the odometer is slowly approaching the 100,000 km mark, I'm thinking about changing the oil in the gearbox and axle)
I decided to take the synthetic oil XADO Verylube 75W-90 GL 3/4/5. It is slightly cheaper than XADO 75W-90 oil due to the absence of revitalizant. Otherwise, as I understand it, there are no differences. I bought the oil in the official XADO store in our city, from Zhenya Spice69. In addition to 3 liters of oil, I also took 3 liters of flushing oil, since the oil in the transmission has not been changed for a very long time, and there is probably a lot of crap in there, and on top of that - changing the type of oil and mineral water to synthetic. I bought the washing on tap, since it is packaged in 2-liter bags, but I need 3 liters) And it’s a little cheaper)
Flushing oil on tap
There is no point in taking 4 liters
Purchases))
Since I have a garage without a pit, I had to solve this issue. In the nearest garage cooperative I found an overpass for 10 UAH/hour.
I stopped by and drained the old used oil from the axle and gearbox. The liquid drained from the box was generally black, and from the gearbox it was a little lighter.
Liquid the color of a dark night :)))
Some chips on the drain plug magnet
Next, fill in the flush. Since I don’t have a special syringe for pouring oil, I bought a 100 ml syringe at the pharmacy and put a piece of tubing on it for convenience.
Kit for refilling oil into units
The process is moving))
After filling, tighten the plugs, jack up one wheel, engage first gear, and wait 10-15 minutes until the car has covered several kilometers in place))))
We are waiting for the flushing to do its job))
The next step is to drain the rinse. The oil that came out of the box was quite dark, and from the bridge, surprisingly, it was more or less light; unfortunately, there are no photos. Well, now all that’s left to do is fill in new oil) As many people advise, when pouring oil into the box, I jacked up the front left wheel so that a little more oil could be poured into the box than the smart book says) Instead of the required 1.6 liters, I got about 1.7 liters of oil . And 1.3 liters in the gearbox. After the operations performed, we finally check the tightness of all the traffic jams, give the uncle the guard 30 UAH, and we are good to go))) Everything about everything took a little more than an hour, with the help of my best friend Yurik2101klasika))))
Without the help of your best friend - nowhere
