Do-it-yourself oil change in a VAZ 2109 box

Manual transmissions of domestic cars, unlike some other components and mechanisms, turned out to be quite reliable. In particular, on a VAZ 2109 car, the gearbox has a large margin of safety, and if you do not violate the operating mode and maintain it in a timely manner, it can easily cover runs amounting to hundreds of thousands of kilometers.

You can read more about what kind of oil to pour into the gearbox here.

One of the important points in servicing a manual transmission on the car in question is changing the transmission oil. It is worth paying tribute to the AvtoVAZ designers: they designed the gearbox in such a way that changing the oil in it with your own hands is quite possible.

This does not require any special devices or specific knowledge. Read about how to fill new oil into a VAZ 2109 gearbox in our material.

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

Popular oil TAD-17I

TAD-17

A common brand of transmission oil for the VAZ 2109, TAD-17I, was created for spur, hypoid and helical, highly loaded gears that operated with contact loads between the teeth of more than 3,000 MPa, but it was not suitable for VAZ 2109 transmissions.

The high viscosity of the lubricant and special additives in the composition, which make the oil film more durable, contributed to the abundant lubrication of the synchronizers, but the oil was not completely squeezed out. Because of this, the angular velocity of the gears and sliding clutch was not equalized, and the gears were engaged with difficulty and with an extraneous sound. At the same time, accelerated wear of the transmission occurred.

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.

Which oil is better?

When choosing a lubricant product for the VAZ 2109 gearbox, you can use the car’s operating manual.
Or you can use the experience of numerous “Nine” owners. The manufacturer AvtoVAZ recommends using mineral all-season lubricants such as:

"Rexol T" SAE 80W-85 class GL-4;
"Omskoil Trans P" SAE 80W-85 universal classification GL-4/5;
"Volnez TM4" SAE 80W-90 class GL-4.

You can also choose a lubricant from other domestic or imported manufacturers. The most important criterion when choosing should be the class of the lubricant.

Since the VAZ 2109 is a front-wheel drive car, it is worth filling in oils of class GL-3 and GL-4 according to the foreign classification or TM-3 and TM-4 according to the domestic one. It is worth remembering that it is impossible to fill a product of class GL-5TM-5. This can negatively affect the gearbox synchronizers.

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.

What to have on hand

Four liters of transmission fluid (the remainder will be used for topping up during operation). The exact amount of oil poured into the gearbox is three liters for a four-speed gearbox and three and a half liters for a five-speed gearbox (Answer to the question of how much oil should be poured).
Suitable location (inspection pit, overpass, which is better - your choice)
A funnel, preferably of a large diameter and with a long end (for convenience).
A key or a head on “17”, you can do both.
Old rags, wipe hands with a probe, perhaps for something else.
A large basin for draining waste liquid and a bottle for overflowing and subsequent disposal (a five-liter canister will do).
In addition, if you have a gearbox without a dipstick, you will need a special syringe, a flexible hose 20 - 25 centimeters long.
Thin wire and electrical tape.

This is the most basic thing that will certainly be needed in the process of work being carried out.

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.

How much oil to put in the box

This can be determined experimentally, but you can spoil a certain amount of oil, which, by the way, is not cheap. If the box is completely empty, then it contains exactly 3 liters. But again, this takes into account the fact that the old oil was completely drained.

It should be noted that there is a special dipstick that can be used to check the oil level. To do this, you need to take out the dipstick, it is located near the battery in the engine compartment, and wipe it with a clean rag. After this, it is inserted all the way and taken out again. If the level is between the maximum and minimum marks, then everything is in order, if it is higher or lower, then you need to either drain or add oil.

There are some nuances regarding filling volumes. In particular, it all depends on how many degrees the checkpoint has. If it is a four-speed gearbox, then fill in 3.1 liters, if it is a five-speed gearbox, then fill in 3.3 liters. More detailed information specifically about your case can be found in the service book.

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.

Semi-synthetics and synthetics

Gearbox oil for VAZ 2109 Liqui Moly

With these types of oils for the VAZ 2109 gearbox, everything is somewhat different, and the main disadvantage is associated with the high price. In general, this is the only disadvantage, but such oils have many advantages:

This type of VAZ 2109 gearbox oil is more technologically advanced and contains multiple additives that reduce wear on transmission parts and extend its service life.
The freezing point of the oil is lower, so even in cold weather you can start the engine and release the clutch after a few seconds.
The oil quickly warms up and becomes fluid, unlike mineral water.
The version that synthetic oil squeezes out oil seals and flows through all connections is a myth.

Instructions for changing transmission oil in a VAZ-2109 gearbox

Changing the gearbox oil is an important part of car care. Over time, the lubricant ages and ceases to perform its functions, thereby causing wear and tear on the device parts. The VAZ Nine gearbox is reliable and durable, but it cannot do without maintenance. The replacement procedure is simple; a motorist can handle this task on his own. Before pouring oil into the VAZ-2109 box, it is important to read the automaker’s recommendations.

What to choose in a car store?

And so we came to the auto store to buy oil in a box for the VAZ-2109. Of course, sellers today are more likely to sell you a more expensive product. However, it is best to give preference to imported oils in the mid-price range. But here we are faced with classification.

GL-4 is an oil that is used for “nines” with front-wheel drive. GL-5 is used in other cases. You can also find combined oils of the GL-4/5 brand; they are suitable for all VAZ-2109. The oil box should be filled with GL-4 or GL-4/5, the viscosity should be as follows: 75w-40, 80W-90. It won’t be difficult to find all this in specialized stores. However, extremely tempting low prices should be avoided. The average temperature range varies from -25 to +40 degrees Celsius. As a rule, the lower the thickening temperature, the better, especially given the harsh winters in our country.

Replacement frequency

Despite the durability of the gearbox, it also tends to wear out and periodically requires attention from the car owner. A scheduled oil change in the VAZ-2109 gearbox should be carried out every 70 thousand km. mileage or after 5 years of operation. However, if extraneous sounds begin to appear from the device, the procedure must be carried out earlier. It is also necessary to take into account the fact in what conditions the car is operated. Sometimes the replacement time is almost halved, for example, for cars subjected to heavy loads, the service interval will be about 40 thousand kilometers.

What tools will we use?

Funnel

Syringe for filling liquid

Liquid container

Keys set

Jack

Changing the lubricant in the VAZ 2109 gearbox is carried out using tools such as:

a syringe for pouring liquid or a funnel;
capacity from 4 liters;
a set of keys;
jack.

Checking the volume and condition of the oil

Every 5 - 10 thousand km. It is recommended to check the level and condition of the oil, as well as the box for leaks. Constant monitoring allows you to protect parts from wear and tear, preventing the need for repairs in a timely manner. The vehicle must be placed on a flat surface during the procedure.

You can check the oil level in the VAZ-2109 gearbox using the dipstick located under the hood. To do this, remove the device, wipe off the grease and insert it back until it stops, then remove it again and evaluate the results.

Ideally, the oil level is at the upper mark of the meter, but if not, then you should definitely add fluid to the required level, and it is important not to overfill the lubricant higher than required. The lower mark of the device shows the minimum permissible value, and if it is lowered, there is already a danger of early failure of the box.

In addition, it is important to monitor the condition of the fluid. Its color, which tends to change over time and is often far from the original, will say a lot. If the oil remains clear but has darkened a little, then this is considered normal, but if it becomes cloudy and looks dirty, it means that a large amount of metal shavings and other deposits have accumulated in it. It is also important to pay attention to the presence of a burning smell. In this case, the box urgently needs to replace the lubricant.

Which oil manufacturer to choose

We have already listed the brief characteristics, and now you can delve into the choice of oil manufacturer for the Samara gearbox. So, who makes the best gearbox oil for the VAZ 2109?

Domestic manufacturers

So:

The gearbox oil declared by the plant is TM-4-12. Ideally, you should use it, of course. This oil was specially developed for the gearbox of this particular vehicle.
Using logic, we come to the conclusion that since it was specially developed, it must be the best. The manufacturer may be different - for example, Rexol.
For example, the M6z12G1 engine oil used in the VAZ 2109 gearbox falls slightly short of the TM indicators.
LukOil SAE 15W-40 is also a good competitor to specially developed oil, TM-4-12. The gap from it is only 4%.

Foreign manufacturers

We analyze the oil for the foreign-made VAZ 2109 gearbox:

The Castrol brand, and more specifically EP-80 and EP-90 oil, which according to the GL-4 class is undesirable for use in Samara gearboxes. Its properties are more suitable for sports gearboxes.
But the foreign company Valvoline, which produced DuraBlend SAE 75W-90 oil, distinguished itself with good performance for our car. This semi-synthetic oil is in second place, after the recommended domestic oil TM-4-12.
On the other hand, the same Valvoline, but no longer GL-4, and GL-4/5 is not suitable for high-quality operation of the VAZ 2109 gearbox.

We remember that the presence of extreme pressure additives has a positive effect on the overall performance of the gearbox. However, too much of them contributes to rapid corrosion of metals. This is because extreme pressure additives include sulfur, which corrodes gears.

From this point of view, motor oils are the best contenders (but we also remember about their other qualities).
And again, semi-synthetic Valvoline turns out to be close to the standard - TM-4-12. But synthetic, on the contrary, turns out to be the most destructive in this regard.

As for other manufacturers, it is worth paying attention to some points and studying the composition of the oil in detail.

Pay attention to:

Viscosity
Oil operating temperature – pour point
Number of additives and their type
Reviews of other drivers on this oil.

For example, according to reviews from VAZ 2109 owners, the following have good qualities:

TNK semi-synthetics
ZIC 75W85 G-FF GL-4

Gearbox oil for VAZ 2109

Mannol semi-synthetic

Some tips for adding oil:

Although the stated characteristics of the VAZ 2109 car indicate that the amount of oil in the box is 3 liters, it is necessary to fill in a little more.
For a 4-speed gearbox you need to fill in 3.3 liters, and for a 5-speed gearbox all 3.5 or even 3.6. This is done so that driving in fifth gear does not strain the car so much.
A very interesting point is the use of special XADO miracle additives, which are supposedly capable of ridding the gearbox of whining. Observing the reviews of 2109 drivers, you can notice some features.
XADO additives do not give the desired effect, and at the same time they have an exorbitant price. It will be much cheaper to repair the gearbox yourself or at a service station with replacement of failed parts.
Check the oil level in the gearbox regularly so that it serves you longer and change the oil on time (70-75 thousand km or earlier if necessary).

Oil options for the VAZ-2109 gearbox

The fact that the operation of the transmission depends on the quality of the lubricant being poured is no longer a secret, but a well-known fact. An incorrectly chosen product can affect the functioning of the device and lead to very undesirable consequences. The Nine gearbox does not require the purchase of extremely expensive oil, but its technical characteristics still play an important role in ensuring stable operation. There are certain recommendations for selecting a lubricant suitable for a given vehicle. The choice should be taken with full responsibility, because the serviceability, service life of the device, as well as the frequency of replacement will depend on what kind of oil is poured into the VAZ-2109 box.

Let's look at the factory recommendations

When selecting transmission fluid, it is better to follow the car manufacturer's recommendations. This ensures the product is compatible with the box and ensures stable operation of the device.

The manufacturer recommends using all-season mineral oils of domestic brands with viscosity characteristics 80W-85, 80W-90:

Omskoil Trans P class GL-4/5;
Rexol T GL-4;
Volnese TM4 GL-4.

The plant poured mineral lubricant from Lukoil into cars, but in practice, in winter, the liquid is not adapted to cope with very low temperatures.

The range of compounds for the Nine transmission is quite wide and is not limited to a few brands. The manufacturer recommends for use oil of classifications GL-3 and GL-4, as well as TM-3 and TM-4 according to Russian standards. You can choose any one that meets these requirements. Semi-synthetic and synthetic lubricants behave much better in cold weather, providing rapid heating and maintaining their properties even at very low temperatures.

It is also equally important to purchase an original product without running into a fake, so you need to buy oil from trusted sellers who have appropriate certificates confirming the quality of the products.

On the very first cars produced, the same oil was used for the transmission that was poured into the engine. This was also recommended by the manufacturer. Now there is no shortage of auto chemicals, so it is better to use specialized products for their intended purpose.

Conclusion

What can you briefly say about the choice of oil for the VAZ 2109 transmission? The use of motor oil in modern cars is undesirable. In addition, it preserves the synchronizers, but corrodes the gears. Using a special gear oil developed for the VAZ 2109 - TM-4-12 - is the best option. Using other gear oils is quite possible, but the choice must be made wisely. Transmission oil should be taken only of class GL-4 or TM-4 and a viscosity of approximately 75W-90. You should choose the manufacturer for yourself - based on your budget, but not forgetting what is written a little higher. But the bottom line is this: there is simply no ideal oil, such that a car will run on it forever! The engine ruins the gears, the transmission ruins the synchronizers. And yet the special oil TM-4-12 remains the best. When choosing it, the main thing is not to fall for a counterfeit product! Happy shopping and may your VAZ 2109 drive for a long time and not break down!

Topping up oil

Regularly checking the fluid level in the VAZ-2109 box will allow you to maintain the device in good condition for many years.

Based on the marks on the dipstick, add oil if necessary. It is very important to keep the transmission fluid level at the maximum level. A drop in volumes to a minimum leads to severe wear and tear on the car's gearbox, as a result of which it is at risk of repair or complete failure. Topping up is carried out using a dipstick and a funnel into the hole of the measuring device, where oil should be poured if the gearbox is serviced. In case the car does not have a dipstick, a syringe is used and liquid is added to the hole in the filler neck.

You should only add a product that is identical to what was used previously; mixing different compositions can have an extremely negative effect on the box.

Consequences of untimely replacement

If the oil is not changed on time, this is fraught with the following problems:

Incorrect operation of the transmission. When engaging gears, the speed may be knocked out, as a result of which the driver will have to activate them again. Usually, due to poor quality fluid, this happens in first gear.
The appearance of noise during engine operation from the gearbox. Extraneous sounds are usually caused by failure as a result of wear of bearing mechanisms. As the oil loses its properties, it becomes less viscous. As a result, the fluid cannot optimally lubricate the internal components of the transmission unit, which leads to premature wear.
Gearbox failure.
The presence of vibrations in the area of the gearshift lever, which may disappear when the engine speed increases and reappear when driving at a reduced speed.

Step-by-step instructions for replacing the gearbox on a “nine”

VAZ produced “nines” with serviced boxes that were not equipped with a measuring probe.

Before the procedure, it is necessary to warm up the transmission fluid so that it drains better. To do this, it is enough to drive 5–10 km, and then drive the car into a pit or place it on a lift.

How to fill oil into a VAZ-2109 box without a dipstick

The process of changing oil in a manual transmission consists of three main stages. When the preparation has already been completed and access to the bottom of the car is obtained, we move on to the next step.

Drain the oil

Remove the rubber cap of the transmission breather, clean it and reinstall it. Unscrew the drain bolt with a 17mm wrench, then tighten it by hand. We pour the waste into a pre-prepared container; about three liters should flow out of the box, provided that the oil level is normal. After we have managed to drain all the fluid from the gearbox, tighten the plug.

Filling with new oil

For boxes with a dipstick, new transmission fluid is poured directly into the hole of the measuring device using a funnel, and it is easy to control the level of the lubricant being poured.

Changing the oil in a VAZ-2109 gearbox without a dipstick is more difficult. The filler neck is located slightly higher to the right of the drain hole, and you will have to measure the level along its edge. We unscrew the plug and pour in the oil using a special syringe with an oil line at the end. When the liquid reaches the upper edge of the hole, stop filling and return the lid to its place.

There is also the option of changing the oil through the speedometer drive hole. In this case, the level of the lubricant being poured is easily visible, but this method is intended to be used as a last resort if it is not possible to carry out the procedure in a standard way.

Instructions

The VAZ 2109 was produced from 1987 to 2011 and therefore these cars have some differences in the design of the gearbox, namely: a manual gearbox can be with or without a dipstick. In this regard, replacing a lubricant has its own characteristics. The replacement should be made on a warm car, that is, after a trip. This will help it drain quickly.

For the basis of the operation itself, the transport must be placed on a lift or inspection pit. If the car is on a flat, horizontal surface, this will help you find out the exact degree of the substance poured into the transmission. A special feature is that in boxes with a dipstick (many new models), the filler hole or the dipstick itself is located on top. You can get to the points where you pour the substance through the open hood.

And many early models do not have a dipstick, but instead there is a filler hole covered with a filler plug. It is accessed from the lower part of the car. Using a syringe, filling in lubricant in both cases is quite simple. So, let's begin the process of replacing the lubricant in the VAZ 2109 car.

Indication of the drain hole Indication of the breather Indication of the drain hole if there is a dipstick Oil on the dipstick marks Drain and fill hole Funnel in the fill hole Filling oil with a syringe

Step 1 - Test the oil level

Without a dipstick, the lubricant level can be checked by supporting your finger or visually. To do this we do the following:

Under the car, in the front lobe, unscrew the transmission filler plug.
If the liquid begins to flow out, then the liquid level is sufficient. If not, check with your finger. The optimal amount of liquid should reach the level of the edge of the filler hole.
You can also check the current degree of lubrication after pouring it into a container. This will show how much substance was in the aggregate.

In many modern models, a dipstick is installed instead of a filler plug. Using it, checking the lubricant number is relatively simple:

Unscrew the dipstick plug.
Wipe off any remaining oil. This is done because previously the substance could have reached above the current level while the car was moving.
We place the clean probe in a “quiet” box.
We take it out and determine how much lubricant is at this moment. In the case when the liquid touches the lower mark (MIN) - the minimum allowed level. The optimal oil level is if it has colored the dipstick to the upper rating (MAX).

Step 2 - Drain the oil

First of all, remove the rubber plug from the breather, then clean the breather while supporting the wire and close it with the plug again. With this action you equalize the internal pressure in the gearbox.
Further, unscrew the bolted drain plug. In both cases, it can be found at the bottom of the gearbox.
Drain the liquid into a previously prepared container. On a “hot” car, the liquid drains faster, but in general it will take several minutes.
After the liquid is drained, the drain hole closes.

Step 3 - Oil Change

In VAZ 2109 cars, the filler hole, like the drain hole, is located at the bottom. To replace we do the following:

We unscrew the drain plug.
Using a syringe, fill the gearbox with lubricant. We stop the procedure when the liquid reaches the edge of the hole.
Close the filler plug.

It is worth noting that for 5-speed transmissions it is worth pouring 300–350 ml more lubricant than normal. Otherwise, when the box is operating in 5th gear, it may “cry” about the lack of fluid, even if it is filled to the brim.

To do this you need:

Raise the side of the car opposite the filler hole with a jack (or any other accessible or convenient way). This will prevent additional fluid from leaking out.
While raised, add additional lubricant.
Close the filler hole with a plug and return the car to a horizontal position.

In order to change the oil in a VAZ 2109 through the dipstick hole, we perform the following procedures:

We find the hood.
We take out the dipstick plug.
Using a funnel or syringe, pour lubricating fluid into the cold hole.
When pouring the substance, you should check the current level while supporting the dipstick. When the level reaches the MAX mark, we stop the filling process.
Close the dipstick plug.

The oil change in the VAZ 2109 gearbox has been completed. Now the gearbox in your car will last longer and will not bother you with faulty operation.

Reviews

Ivan, Krasnoyarsk. The car was produced in 2003, version with a 1.5-liter carburetor for 70 horses. The engine is simple and reliable, which cannot be said about other components and assemblies. Although the suspension is energy-intensive, it lacks strength due to low-quality components. Fortunately, chassis parts can be found at any car market. The five-speed manual pleases with the accuracy of switching at low accelerations, but otherwise there may be jerking and engine overheating. Overheating occurs especially in summer.

Mikhail, Taganrog. I drive a rusty nine, produced in 1999, a car with 155 thousand km mileage. Equipment with 1.5 engine and non-alternative manual transmission. Gasoline consumption is from 9 to 11 liters depending on driving style. The box is annoying with hum and vibrations, which are a design feature and cannot be overcome in any way. But on the other hand, the car feels better this way) I also like the angular design of the nine in the style of the 80s - the car is immediately recognizable in city traffic.

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.

During operation, we check the fluid level every 10 - 15 thousand kilometers in order to avoid transmission breakdowns due to low oil level. If the gearbox consumes a lot of oil, it should be replaced as often as possible.

On VAZ 2109 (21099) cars of earlier versions, the dipstick was not installed; if you have such a car, the replacement process is carried out slightly differently.
The oil fill hole is located on the right side of the gearbox housing.
We remove the plug, take a syringe and, using it, pour oil into the box.
To avoid overfilling transmission fluid, focus on the lower edge of the oil filler hole.

It is recommended to carry out this process with a warm engine, since liquid oil drains better from various components and parts of the car. If the replacement is carried out in winter, then it is advisable to drive the car for at least 10 minutes.

Then the car is placed on a pit in the garage (overpass), after which you need to climb under the car and unscrew the filler hole to provide air access. You can also lift the car with a jack, but the side of the car opposite the hole should be higher.

A container is first placed under the drain hole and the drain plug is completely unscrewed. Approximately 3 liters of liquid should pour out. You can tighten the plug if the liquid begins to flow in a thin stream or stops flowing altogether.

What you need to change the oil

To replace it yourself, you will need at least the following:

jack, inspection hole or lift;
wheel bolt wrench;
open-end or socket wrench 17;
empty waste container;
a syringe or other device for pouring oil;
clean rags.

When preparing for a replacement, there are a few things to consider.

It is necessary to take into account how much oil is in the VAZ 2109 gearbox. That is, the container for the old lubricant must be selected appropriately, so as not to subsequently collect spilled waste. If you are the only owner of the car, are replacing it for the first time and are sure that there have been no unqualified interventions before, then the maximum volume of oil in the box will not exceed 3.3 liters. Accordingly, a 4-5 liter canister is quite suitable for this purpose. If the box has a dipstick, you can first check the lubricant level. Often a plastic 5-liter bottle of technical liquids is used as a waste container.
It is necessary to take care of safety. Changing the oil in a manual transmission requires a person to partially remain under the front wheel arch. Therefore, it is important to follow at least two basic rules: securely stop the car and install a safety stand in case the jack falls.
