How to change the oil in a VAZ 2109 gearbox with your own hands

Changing the oil in the gearbox on VAZ 2108, 2109, 21099 is not a difficult job; anyone can do it with their own hands. The first time will be longer than all the subsequent ones. Therefore, there is simply no point in going to the service for such a trifle. The main difficulty of the whole work is to fill the gearbox with oil, since the design does not allow you to get to the opening of any container with new oil. We will talk about changing the oil with and without a dipstick, on carburetor and injection models. But everything will be discussed in order in this article.

Many people ask: “When should you change the oil?” It all depends on the operating conditions of the car. If the car is constantly used in severe weather conditions (severe frost, heat, snow, dirt, dust, etc.), then we recommend changing the oil every 35 thousand km. In urban asphalt operating conditions, it is sufficient to replace it once every 40 thousand km.

Closer to 35-40 thousand km. mileage since the last oil change, the vehicle's transmission may not operate stably. You may feel increased vibration of the box, excess noise, and inaccuracy in gear shifting. And if there are no problems with the clutch, then these are all signals for diagnosing and changing the oil in the gearbox on VAZ 2108, 2109, 21099. Injector, carburetor, with or without a dipstick - it doesn’t matter, this applies to all models. We recommend changing the oil in all components of a used car after purchasing it.

To change the gearbox oil with your own hands you will need:

New original gearbox oil. We recommend using oil recommended by the manufacturer, and also depending on the temperature conditions of the vehicle's operation (for example, 80W-85. GL-4432). Don’t forget that you will need 3.3 liters to change the oil in a five-speed gearbox, and 3 liters for a four-speed gearbox.
Spanners 12 and 17
A container for draining used oil with a volume of at least 3 liters.
Syringe for filling oil (for gearboxes without a dipstick), funnel (for gearboxes with a dipstick)
Hose or flexible tube 20-25 cm, electrical tape (for gearbox without dipstick)
Clean rag
Thin but strong wire
Pit, overpass or lift.

Do-it-yourself removal and replacement of the VAZ 2108, 2109, 21099 wheel bearing
Before replacing, be sure to heat the oil by shifting gears with the engine running or drive a few kilometers. It takes 5-10 minutes for the oil to drain completely from parts and mechanisms.

Let's move on to the sequence of actions. So…

Reasons for changing transmission oil in a VAZ 2109 gearbox

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

When extraneous sounds and creaks appeared. 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.
If the transmission fluid has become dark or black in color, it should be replaced regardless of the vehicle's mileage.
Purchasing a used car. Especially when it is unknown how long ago the former owner changed the fluid.

The dipstick, which has 2 max and min marks, will help you find out the level of transmission fluid in the VAZ 2109 gearbox - you need to add it if the level is below the min mark

Replacement steps

The entire process of replacing the lubricant in the gearbox can be divided into three main stages:

Checking the lubricant level;
Draining old oil;
Pouring new lubricant into the box.

Let's go through each stage separately.

Level check

Checking the current oil level in the gearbox is not difficult, regardless of whether you have a dipstick or not.

If the dipstick is missing, we will check with our finger. This is done as follows:

Under the car, unscrew the filler plug from the gearbox;
If after this the liquid begins to flow out, the level is sufficient. If not, insert your finger into the hole. Having felt the liquid at the level of the edge of the filler hole, we can talk about the optimal amount of lubricant;
You can visually drain all the lubricant and, by its quantity in the container, determine how much liquid was in the system.

If you have a probe, everything is simple:

Unscrew the plug on which the measuring probe is attached;
Wipe it with a dry cloth;
Place back into box. In this case, the machine must be on a flat surface and at rest;
Take out the dipstick and see what the meter shows. It has Min and Max marks. It is optimal if the oil stains the dipstick up to the maximum mark, but not above it.

In order for the new lubricant in the gearbox to work effectively, the first step is to get rid of the old one. The transmission oil is drained quite easily.

To drain the lubricant from the gearbox you need:

Remove the rubber plug from the breather, clean the breather with wire and close it with the plug. This will help equalize the pressure inside the gearbox.
Unscrew the drain plug. In old and updated versions of the VAZ 2109, this plug is located the same way - at the bottom of the box.
Drain the oil into a container of about 5 liters prepared in advance.
After draining all the lubricant, screw the drain plug back securely.

When the engine is warm, the fluid from the gearbox will drain faster and more efficiently. But at the same time, follow safety precautions. After all, you are working with hot oil.

Replacement

Now we have reached the point where we need to fill in new lubricant. We have already determined which one.

Unscrew the filler plug located at the bottom;
Using a syringe, gradually fill the gearbox housing with fresh oil;
Add until the liquid is level with the edge of the filler hole;
Close the plug.

An important difference is the gearboxes on the VAZ 2109 with 5 speeds. They require approximately 300-350 milliliters more lubricant to be poured. Otherwise, when operating in 5th gear mode, the gearbox will experience oil starvation.

Transmission oil change intervals

Recommendations from the manufacturer of your vehicle help us figure out how often the transmission oil needs to be changed.

In particular, if you own a domestic VAZ-2109 car, then it is necessary to replace the transmission fluid every 60 thousand kilometers.

However, let us hasten to make small adjustments. If you operate your car in difficult conditions, forcing you to travel long distances on poor quality roads, then it is best to fill in new oil in the gearbox after a run of 30 thousand kilometers.

We also recommend learning to hear your own car. Listen for any sounds that were not previously apparent when shifting gears. If you begin to notice suspicious squeaks, if every attempt to change gear is accompanied by even minor difficulties, then it’s time to change the TM. Replacement will also be required in cases where the clutch does not work.

Every car can have a breakdown. For example, noise appears in the gearbox, gears shift worse, and so on. But this does not mean that it is worth completely disassembling the gearbox or replacing it. Things may be different here.

How much oil should be poured into the box of a VAZ 2109?

Noise in the VAZ 2109 gearbox when driving may occur due to a low oil level in it. Therefore, first, check its level in the gearbox. If necessary, replace it. But how often do you change the oil in the VAZ 2109 gearbox? So, for VA, Z, an oil change should be done every 5 years . In terms of mileage, it is enough for 70 thousand kilometers. Drain the oil through a special drain plug, which is located at the bottom of the box. So now you know how long to change the oil in the box of a VAZ 2109, which is not unimportant!

Important : the oil in the gearbox can remain unchanged for quite a long time.

How much oil to pour into the box of a VAZ 2109:

3.0 l with 4-speed gearbox;
3.3 l if the gearbox has 5 steps.

To store oil, it would be a good idea to purchase a 4- liter canister. It is convenient and quite practical. It is advisable to keep it in the garage and, if necessary, add oil to the box.

The gearbox is designed to increase traction force with its subsequent transfer to the drive wheels of the car. This device is considered to be the most stable and “long-lived” in a car. Its malfunction can be easily eliminated and they occur in the gearbox much less frequently than in other parts of the car.

What tools are needed to change the oil?

To pour oil into the box, you should use special tools:

Funnel;
Socket wrench 17;
Bucket for draining;
A special filling syringe, if there is no dipstick;
A rag to wipe the dipstick and hands.

About types of transmission oils

For VAZ 2109 vehicles, it is recommended to use the following types of gear oils:

API GL-4
SAE

Let's talk about each of these types in more detail.

API GL-4

These gear oils are suitable for use in a variety of conditions from light to heavy and are used in synchronized gearboxes.

SAE

The most popular classification of transmission oils. The following types are suitable for the VAZ 2109 box:

Mineral 85 W This type of oil is perfect for gearboxes with high mileage. It has good lubricating properties in hot weather due to its good viscosity and thickens at low temperatures.
Semi-synthetic 75 W Lubricating properties at a high level. In warm climates it remains quite viscous. In winter it warms up quickly. Reduces noise during gearbox operation
Synthetics 75 W In summer, due to high temperatures, it becomes liquid. Particular attention should be paid to the gearbox seals; oil leaks are likely; it does not thicken in the cold.

Author's advice: When choosing gear oil for a VAZ 2109 gearbox, you should take into account your financial capabilities and the recommendations of specialists.

Some more useful information

We have already decided what kind of oil to pour into the VAZ-2109 box and how much is needed. Now I would like to say a few words about what high-quality gear oil should be like. Since lubrication in the gearbox is extremely important and work is simply impossible without it, you need to use only a high-quality product that has already proven itself in the market.

Synthetic-based oils are more preferable for severe winters, when the temperature drops to -30 at night. Synthetics do not thicken as much, which allows you to start the car the first time even under such conditions. Mineral oils are less expensive, but do not perform well at sub-zero temperatures.

Checking the oil level in the VAZ 2109 box

The easiest way to monitor the oil level in the gearbox is with a dipstick. But where is the oil level dipstick in the VAZ 2109 gearbox and what is it?

The probe looks like a metal strip at one end of which there is an o and “max”, and at the second, opposite end, the part ends with a black rubber ring.

Checking the oil level using a dipstick:

Place the car on a flat surface.
We wait the required fifteen minutes.
We stock up on rags.
Open the hood.
On the side of the driver's fender we are looking for the black rubber ring of our part. It is located on the gearbox directly under the air filter tube for air purification.
We take out the found ring.
Wipe it dry with a rag prepared in advance.
Carefully, without touching the walls, put the dipstick back until it stops.
We take out and inspect the marks on the dipstick.

The optimal oil level in the VAZ 2114 gearbox shows about. If the actual level is below this mark, then the oil should be added.

DIY oil change

You can perform this operation yourself, since there are no particular difficulties when replacing the lubricant, and you do not need special equipment or tools.

Instructions on how to change the lubricant in a VAZ gearbox with your own hands were shared by the VAZ 2101-2107 REPAIR AND MAINTENANCE channel.

Tools and materials

To replace, you need to prepare the following:

New lubricant for filling into the gearbox. The volume of liquid depends on the design of the mechanism.
An empty container for collecting waste liquid, the capacity of which should be slightly more than 3 liters.
Rags.
Socket wrenches for 12 and 17.
A syringe with a hose for a gearbox without a dipstick, a funnel or a rubber bulb for boxes with a dipstick.

Before starting work, you need to warm up the lubricant in the transmission; to do this, just drive 10 km.

Drain the oil

Before adding new lubricant, it is necessary to drain the old oil that has used up its life. This process takes no more than 15 minutes.

The procedure will be as follows:

The machine is installed on a lift or inspection hole.
Use a rag to wipe the filler and drain plugs.
Using a 17 key, slightly unscrew the filler cap to release air from the gearbox.
Place the empty container under the drain hole and unscrew the plug.
The waste is drained, and after the liquid has flowed out, the lid is replaced.

While the waste fluid is draining, inspect the drain plug for metal shavings. If it is detected, you should flush the gearbox housing.

Filling with new oil

The algorithm for pouring oil into serviced and unserviced VAZ 2109 gearboxes is the same as for adding oil.

Adding fresh oil

How else can you add lubricant?

In order to fill in the required amount of fresh lubricant, you can resort to another method.

This operation is performed through the installation location of the speedometer drive:

Thoroughly clean the area near the speedometer drive from various contaminants.
Then unscrew the nut securing the speedometer cable.
The speedometer drive is moved to the side and protected from possible contamination.
Fill the lubricant using a large rubber bulb - the larger it is, the faster the adding process will go.

The required level of transmission oil in the box is determined by the appearance of lubricant from the filler hole. As soon as you see a stream of liquid, the filler plug must be tightened.

In the video from the Home Master channel, you can learn about the procedure for changing the oil in the VAZ 21099 gearbox, which is similar to the process in the VAZ 2109.

Step-by-step instruction

In order to change the oil in a VAZ 2109 gearbox, we perform the following steps:

Start the car and drive it for a drive, during which you engage each of the gears and let it run for a while. This will help warm up the box and thin the oil, giving it maximum fluidity.
Place the machine over the pit and place a container under the front to collect the oil.
Open the hood. Remove the crankcase protection.
Remove the cap from the breather. Clean the breather and its cap from dirt.
Remove the dipstick. Unscrew the drain plug and wait until the old grease drains out completely.
Screw in the drain plug. Using a large syringe or bulb, pour the required amount of new lubricant into the dipstick mounting hole.
Reinstall the dipstick. Place the cap on the breather.

Thus, changing the oil yourself is a completely simple operation that anyone can do. The only thing you should remember is the need to check the level some time after the replacement and, if it is low, add the missing amount of oil.

Step-by-step instructions for changing gearbox oil:

Before starting the draining procedure, it is strongly recommended to warm up the VAZ 2109 to 70-80 degrees - this procedure will make the oil more liquid, which will allow it to completely drain from the gearbox.
Also, many car enthusiasts claim that with each oil change it is also necessary to clean the breather, well, this is not so difficult to do: remove the rubber cap from the gearbox, clean it, clean the breather and put the cap back in place.

You can fill the oil into the filler hole

You can only pour oil into such a gearbox using a special syringe or a homemade bulb.

fill in new transmission fluid

That's all, changing the oil in the gearbox on a VAZ 2109 is complete. After the replacement, you will probably notice that the gears will change much smoother and the box itself will make much less noise.

Do not forget to change the transmission fluid in the gearbox on time and it will serve you faithfully for many years.

Possible reasons why an oil change is necessary

It is worth noting that in model 2109 (21099) and others like it, the gearboxes are, so to speak, “indestructible”. But even such a reliable unit has periods when, for further uninterrupted operation, it is necessary to carry out maintenance in the form of replacing the transmission fluid. If rustling or other noises begin to be heard from the box, the unit produces strong vibrations, gears shift worse and are accompanied by unpleasant sounds - the time has come for an oil change. To begin with, check the oil level with a dipstick (if the replacement was made recently), and inspect the unit itself for leaks. Only then proceed directly to the replacement itself.

Direct replacement (manual transmission with a dipstick)

Replacement is carried out with the box heated to operating temperature (so that the maximum amount of waste and wear products drains out).
Using a rag and thin wire, clean the breather and rubber cap (after cleaning, return the cap to its place).
We unscrew the drain plug and drain the waste liquid into a specially prepared container, then return the plug back.
We take out the dipstick and pour transmission fluid through the hole (using a funnel), wipe the dipstick with a rag and install it in place.
We wait five minutes and then take out the dipstick and measure the oil level, adding it if necessary.
