Choosing oil for a VAZ 2107 box: volume and how to fill

The service life of the gearbox depends on the quality of the gear oil. If its physical properties or level (quantity) do not meet the required parameters, gearbox parts begin to wear out rapidly. You can add oil to the VAZ 2107 gearbox or change it yourself. This operation does not require high qualifications and special tools. You just need to know what kind of oil can be poured into the “Seven” gearbox, when and how to change it, it needs to be changed or topped up.

Reasons for changing gear oil in a VAZ 2107 gearbox

Replacing the transmission fluid in the “seven” box may be necessary for the following reasons:

When extraneous sounds and creaks . Gradually, the liquid loses its properties, and particles of metal and moisture can get into it. In turn, this leads to accelerated wear of parts.
Purchasing a used car . Especially when it is unknown how long ago the former owner changed the fluid.

The dipstick, which has 2 marks: max and min you find out the level of transmission fluid in the VAZ 2017 - you need to add it if the level is below the min mark.

Do I need to use a flush?

Flushing should be done every 2-3 oil changes in the gearbox. This contributes to:

Softening and removal of deposits, wear products, etc.;
Cleaning channels, which improves the circulation of lubricating fluid;
Complete removal of old oil;
Extending the service life of oil seals and rubber seals.

It follows from this that by neglecting the recommendations and not using flushing, you can clog the box with excess deposits. This may subsequently damage the mechanisms inside the box.

Transmission oil change intervals

In the owner's manual, the car manufacturer indicates the exact period between replacements. According to this document, the transmission fluid must be changed once every 3 years or every 60 thousand km of the vehicle. Unless, of course, there are other reasons to replace it ahead of schedule.

Replacement recommendations:

The lubricant should be changed in an inspection pit, overpass or using lifts.
To ensure that the old mixture flows out quickly and completely, replacement should be done when the engine is warmed up to operating temperature.
During replacement, you need to pay attention to the presence of metal components in the drained liquid. If such chips are present, then it’s time to start repairing the transmission.

The five-speed gearbox of the VAZ 2107 has a certain nuance. A little more transmission fluid should be poured into it - approximately 250 ml. This is due to the design features of the gearbox

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.

Brand and volume of oil for gearbox VAZ 2107

VAZ 2107 gearbox has two modifications - five-speed and four-speed. And depending on this, the volume of liquid poured varies:

Four-speed gearboxes require 1.35 liters.
For five-speed gearboxes, 1.6 liters are required.

It does not depend on the number of stages which oil should be filled. It must be a special transmission, selected according to the recommendations of the car manufacturer. That is, the liquid must correspond to the operating conditions of the vehicle.

Some brands of lubricants that can be poured into the VAZ 2107 gearbox:

Lukoil TM-5 85W90
TNK Hypoid 80W90
Spector 80W90
Shell Spirax S5 75W90 GL4/5
Novoil Super T 80W90
Spectrol Forward 80W90
Agip Rotra MP 80W90/80W95
Norsi Trans 80W90/85W90
MP Gear Lube-LS 80W90/80W140 (GL-5)

Which oil to choose

You should know what kind of oil to pour into the VAZ-2107 box. Only special gear oils of the following groups need to be poured into the classic box: GL-4 and GL-5. Lubricant viscosity can be: SAE 75w-85, SAE 75w-90, SAE 80w-85. The advantage of mineral lubricants is their low price. In severe frosts, such oil begins to thicken and does not fully perform its functions. Synthetic gear oil better protects gearbox mechanisms at ultra-low temperatures (down to -40 degrees).

Checking the oil level in the gearbox

The transmission fluid is checked every 10 thousand km. Essentially, during periodic maintenance (according to the manufacturer’s regulations).

Before you start checking the fluid level, you need to let the car sit for a while. This will allow the oil to flow down the walls of the gearbox.

To check the lubricant level:

The key is 17.
Steel brush and rag.
A screwdriver or other suitable object for measuring the level.
A special syringe to add oil if necessary.

Steps to check the transmission level:

Place the car on an overpass or in a pit (you can use lifts).
Find the oil filler and drain plugs.
Using a steel brush and rag, clean the plugs and the crankcase surface around them from dirt.
Using a 17 mm wrench, unscrew the filler plug.
Using a screwdriver or similar suitable object, measure the oil level. It should reach the bottom edge of the hole.
If the transmission fluid level does not meet the required level, the lubricant must be added. This can be done using a special syringe. At this point, you can check the condition of the oil.
To complete the process, tighten the oil filler plug.

If you notice a strong drop in the fluid level , you need to check the condition of the gearbox seals. Under no circumstances should there be drops of transmission oil on the gearbox housing. At the same time, the presence of oil fogging is quite acceptable and does not indicate damage to the seals. It is imperative to check the fastening of the gearbox housing covers and, if necessary, tighten the nuts. If after all the steps the oil continues to flow, the gaskets and/or seals need to be replaced.

When to change

The operating instructions for the car state that the factory oil in the VAZ-2107 manual transmission is enough for 80 thousand km. Unfortunately, cases often arise that by this point the oil will not only lose its lubricating properties. Moreover, the gearbox itself will also become unusable, given the difficult climatic and road conditions in Russia. Therefore, it is recommended to change the oil at least every 50 thousand km, or even earlier. In any case, the condition of the fluid quality can be checked at any time using a dipstick. You need to pull it out of the filler hole and see how clean or dirty it is.

The process of changing the oil in a VAZ 2107 gearbox

After choosing the oil, you can proceed directly to changing it. So, for the process of changing the lubricant itself you will need:

New gear oil, selected taking into account all recommendations.
12 mm hex key.
17mm wrench.
Container for draining used lubricant. Alternatively, you can use a plastic bottle, cutting off the top.
·Dry cloth.
Brush with metal bristles.
Special grease syringe (grease gun). If you don't have a grease gun on hand, you can use a funnel with a long flexible tube attached to it.

What is needed for replacement

You can replace the transmission fluid yourself. With proper preparation and a little skill, the entire procedure will take about an hour. You must first purchase the required type of lubricant and prepare the following tools and accessories:

drain container for waste liquid with a volume of about two liters;
a special syringe or homemade device (bottle, tube) for filling transmission oil;
a seventeen-size wrench and a twelve-size hexagon;
protective gloves and rags for cleaning surfaces.

Sequence of work

To do this you need to complete the following steps:

First of all, the oil must be warmed to operating temperature. This can be done by driving a few kilometers.
The car needs to be driven onto an overpass or inspection hole and put on the handbrake.
Find the drain and fill holes.
Clean the transmission housing and oil fill and drain plugs using a wire brush and then a rag.
Place a container under the drain hole to drain the used oil.
Using a hex wrench, unscrew the drain plug.
Drain the waste. You should be careful at this point, as the oil is very hot.
Clean the drain plug from dirt and screw it into place.
Carefully inspect the drained lubricant. If there is metal dust in it, then the gearbox requires repair.
Insert the grease gun into the oil filler neck and fill in the required amount of oil. Typically, liquid is added until it begins to flow out of the filler hole.
Screw the oil filler cap into place. The oil change is complete.

The same fluid is poured into the gearbox and rear axle gearbox. Therefore, it is better to change the oil in these units at the same time.

For those cars whose boxes have a dipstick for checking the oil level, the steps are as follows:

Find the drain cover on the gearbox.
Remove the rubber cap from the gearbox and clean it. At the same time, clean the breather, then return the cap to its place.
Place a container for waste fluid under the crankcase and unscrew the drain cap.
Wait until the oil drains completely.
Screw the drain plug into place.
Pull out the dipstick showing the oil level in the gearbox.
Insert a funnel where the dipstick was and add fresh fluid.
While pouring lubricant, you need to monitor the level using a dipstick.
The fluid level should be midway between the minimum and maximum marks.

A little theory

Which oil is better to choose?

First, let's look at what kind of oils there are and which oil is intended for what purpose. According to the SAE classification, the oil is designated as 75W-90. What does this mean:

According to the SAE lubricant classification, oils are divided by viscosity and temperature characteristics. So, 75W is a viscosity indicator, and 90 is a temperature indicator.
An oil with a viscosity index of 75W-90 (w means winter) has a kinematic viscosity of 4.1 and a melting point Celsius of -40 degrees.
The gear oil for your car should be selected based on the ambient temperature.
Thus, oils with an indicator of 75W have a minimum temperature of -40 degrees, 80W - -26 degrees. Both 75W and 80W have a maximum ambient temperature at which the oil behaves normally + 35 degrees.
85W-90 oil has a maximum temperature of 45 degrees, but its minimum is -12 degrees.
So the most commonly used gear oil is SAE 75W-80 and 75W-90.

New front-wheel drive VAZ cars began to be filled with regular engine oil in the gearbox. In this regard, many car owners wondered: is it worth changing the transmission oil or leaving it as it is:

The head of the AvtoVAZ fuel and lubricants laboratory reports that it would be best to replace the oil with normal transmission oil. He recommends using API GL-4 oil. You can also use GL-5, but it is not necessary. According to the head of the laboratory, the noise level should immediately decrease and gears should change easier.

Lukoil gear oil

Conclusion: on a VAZ 2115, changing the best transmission oil involves draining the engine and filling in the transmission oil!

As for the manufacturer of gear oil, AvtoVAZ engineers give preference to brands such as Lukoil, TNK Trans KP and ESSO. Although this is recommended, you can fill in oil from any manufacturer.

Do not buy cheap oil - it may turn out to be a fake, and then you risk going broke on gearbox repairs.

When should you change the gearbox oil?

When to change the oil in a VAZ gearbox

So:

The gearbox oil is changed after a certain mileage or time. It all depends on the oil used, as well as the car.
Typically, the oil in the variable gearbox is changed at intervals of 30-40 thousand kilometers of the vehicle. On some of the latest VAZ cars, the plant has established a frequency of as much as 75 thousand kilometers.
The standard mileage is different for each car, but the oil can be used to determine the need to replace it.
To do this, when changing the oil in the car engine (every 10 thousand km), check the oil level in the gearbox. If necessary, it must be topped up. And by the color you can determine the need for replacement.
Used oil is black or gray in color and may also contain metal dust or shavings from transmission parts.

How much oil will you need:

For Classic – 2 liters
For Samara - 3.3 liters
For VAZ 2110 – about 4 liters

Changing transmission oil for VAZ 2114 - 3.3 liters of oil in the gearbox
