How much oil to fill in the box of a VAZ 2115 injector 8 valves

VAZ-2115 is a four-door sedan, which is a representative of the Lada Samara family. Production of the model began in 1997 on the basis of the predecessor VAZ-21099. The new car differed from it in the design of the front and rear parts of the body, as well as a more modern interior. External changes turned out to be more significant than those of the VAZ-2114 hatchback, which is one of the 2115 versions. In addition, the “fifteenth” received an upgraded suspension and braking system.

The car was initially offered with VAZ-21083 1.5 liter (72 hp) carburetor engines, and in 2000 the VAZ-2111 engine with distributed fuel injection became available. Its working volume was 1.5 liters and its power was 78 liters. With. In 2007, a newer VAZ-11183 unit with a volume of 1.6 liters (81 hp) appeared. The last restyling of the VAZ-2115 took place in 2008, which made it possible to extend the relevance of the model until 2012.

How much oil is in the VAZ-2115 gearbox?

The VAZ-2115 car is the result of numerous modernizations of the well-known VAZ-2108 model. The machine is easy to use, and its high reliability is due to inexpensive spare parts, even despite the unpredictable frequency of breakdowns. The VAZ-2115 is an outdated car in all respects, and yet, people continue to buy it. Low cost of operation and maintenance, the possibility of self-repair are the key advantages that the VAZ-2115 has today compared to foreign cars. Thus, one of the most common procedures is the replacement of consumables. For example, every motorist can cope with changing the oil in the gearbox. This task does not require any special skills and is performed with improvised means. But it should be noted that the reliability of the gearbox depends on the quality of the oil, which still needs to be chosen correctly based on the parameters, the best brands, the frequency of replacement, as well as the volume of oil being poured. This article will be relevant for owners of the VAZ-2115, regardless of the year of manufacture of the car.

What you need to know about choosing the right oil for the VAZ-2114

What kind of oil should be poured into the box of the VAZ-2114?

The manual transmission of this car has long been famous for its durability and reliability. But in many ways, the quality of the product depends on you and on the correct choice of lubricant. Firstly, choosing a product for your car can and should begin by considering the oils that VAZ itself recommends for use. These tips are quite easy to find, just find those. documentation that you received when purchasing your car, and find a separate list there that will contain a list of oils and lubricating fluids.

Well, that's all, take and pour what the manufacturer advises, but not everything is so simple. The quality of the offered oils is very often questioned by experienced drivers and car enthusiasts, and this negative review is certainly not without truth. If you look at it in reality, almost always after changing the factory product to an imported manual transmission in a VAZ-2114 it starts working very smoothly, quietly and softly.

The main thing is to consider the right product option based on all the recommendations and advice.

What is the reason? Not all liquids will be able to reveal their functionality to the maximum in the VAZ-2114 box, and some will not even work. Don’t forget about your personal conditions for using the car.

Here's what the VAZ manufacturer can offer us:

Experienced car enthusiasts advise buying transmission fluid from Lukoil.

75 W 90 GL -4 is a semi-synthetic with more advanced characteristics, which is recommended by AvtoVAZ. The oil is a leader in its price category and, in principle, performs excellently at both low and high temperatures.

If you look at the disadvantages of this liquid, then this product has quite a high noise level during operation compared to other mineral-type or semi-synthetic oils.

If you choose 80W90 GL-4 oil, then you will spend less money than on synthetics, and the gearbox itself will make less noise. Well, here, of course, there are some drawbacks:

1. In cold seasons, the liquid tends to freeze, that is, the gears will not respond well to your actions until the oil warms up.
2. The product has deteriorated anti-corrosion and protective properties.

If you are not satisfied with Lukoil, then there are several replacements for this manufacturer:

By the way, be very careful when choosing an oil, since professionals in the auto service industry do not advise choosing too expensive synthetic oil or too cheap mineral water for the VAZ-2114 gearbox.

If you look at reality and choose what kind of oil to fill into the box of a VAZ-2114, then proven 75W90 GL-4 oils are best suited for you, you can make an improvised mixture and add GL-5 (you can do this only when you understand why this), but do not think of adding exclusively the second option, it serves only as an auxiliary liquid.

This choice will help your gearbox operate as smoothly as possible, protect it from various debris, eliminate excess noise and, most importantly, bring you comfort on the road.

Even under all these conditions, you will not incur huge waste on lubricant. Expensive synthetics for a VAZ-2114 car are simply not required, since your car does not have a special load on the transmission.

And yet, a very expensive synthetic oil will not last much longer than a mid-price semi-synthetic oil, so it’s better to change the oil several times than to drive an expensive one all the way and ruin your car!

How many liters of oil to pour into the VAZ 2114 gearbox

Your car can hold 3.5 liters of oil, but it is only possible to fill the transmission to 3.3 liters. All this is due to the fact that when the old product is drained, a small amount of liquid remains in the gearbox.

3.3 liters of oil

Oil viscosity. Which one to choose?

Here we come to the end. If you have not yet figured out which oil you will choose, we recommend that you take into account such a factor as the viscosity of the liquid.

Here you should pay attention to the weather conditions in which the transmission operates.

If your winters are not too cold and the average temperature reaches -15 degrees, then you can choose 80W90 without much thought. But if the temperature in your area drops lower, then 75W90 is a good choice.

Bottom line: Take into account the weather conditions and the particular use of the machine when choosing oil. In almost all cases, a product like 75W90 will work for you.

The best motor oil. does it exist?

• Frequent driving at high speeds
• Sharp maneuvers
• Driving on bad and dusty roads, including off-road
• Temperature changes, when frosts are replaced by sudden warming, dirt and slush on the roads
• Frequent engine operation at high speeds, which causes overheating and rapid wear of transmission parts

Russian motorists are well familiar with these so-called risk factors. Knowing about possible problems, they prefer to change the oil twice as often as specified in the regulations - for example, after 50 thousand kilometers. The regulations can be reduced even further if the machine is subjected to increased loads almost continuously. In addition, in such cases, it is advisable to check the volume of oil in advance, and at the same time monitor its condition.

Prerequisites for changing the oil

• The mileage since the previous oil change is approaching 60,000 km. Using a lubricant for a longer period of time will result in loss of lubricating properties. The wear of gearbox elements increases.
• the appearance of extraneous noise in the gearbox. Difficulty when shifting gears. A grinding noise when shifting gears, a constant humming noise that occurs at certain speeds.
• the presence of a large accumulation of metal shavings or black color of the oil. Determined by visual inspection of the oil dipstick when checking the lubricant level.
• burning smell. With heavy loads on the transmission. Using low gears at high engine speeds.
• change of season.

Checking the volume and condition of the oil

The fluid level in the VAZ-2115 manual transmission is determined with a dipstick, which has Max and Min marks. If there is not enough oil, the oil mark on the dipstick will be below the Min level. In this case, add oil until it rises above the Min mark, but does not exceed the Max mark - this position is considered the most optimal.

If the fluid has darkened or become cloudy, emits an unpleasant odor and contains a suspicious sediment, then the oil should be completely replaced. In such a situation, topping up alone will not be enough.

Choosing oil for VAZ-2115

For the VAZ-2115 gearbox, oil with certain viscosity parameters should be selected based on the climatic conditions in which the car is most often used. In this case, the manufacturer allows the following standards: 80W-85, 75W-80 or 75W-90. Fluids with a higher viscosity (for example, 85W-90) are incompatible with the VAZ-2109 gearbox.

After reviewing the parameters, we select the manufacturer. Recognized brands with good reputations include inexpensive products from Lukoil, Rosneft, Valvoline, Kixx, Mobil, G-Energy, Elf, Castrol, Shell and others.

You also need to pay attention to the following types of oils - synthetic, semi-synthetic and mineral. The best option for the VAZ-2115 in terms of price-quality ratio would be semi-synthetics. But if finances allow, you can safely take synthetics.

How to pour oil into a box of a VAZ 2114 - useful tips

Every owner of a domestic car should be able to choose the right oil for the VAZ-2114 gearbox, because if the oil is chosen incorrectly, one can only dream of the reliability and stability of the transmission. Choosing gearbox oil in domestic cars is not as difficult as it seems; even a novice car enthusiast can cope with it; all you need to know are a few important rules.

Experts will help you decide in this article about which manufacturers produce the best oil for the VAZ-2114 gearbox and who is best avoided.

How to choose the type of oil for a VAZ-2114 gearbox

What base the oil will have doesn’t really matter, so you can buy both mineral and synthetic. If you look at cost and consumption, then it is more profitable to opt for a mineral substance

What criteria should you pay attention to?

1. What is the relative sliding speed?
2. The magnitude of the specific loads acting in the internal space of the mechanism.

These criteria are influenced by the best oil viscosity selected specifically for your car, as well as the required number of additives. Extreme pressure additives are a desirable feature because while the sulfur components contained in the fluid cause metal defects, they also form scuff marks, which over time form a thin film that slows down the wear process. This allows the mechanism to work longer even in the harshest climatic conditions, and the issue of metal defects fades into the background.

What other types of gear oils are there:

1. GL-4 – suitable for the gearbox of front-wheel drive vehicles.
2. GL-5 – are considered the most universal, suitable for domestic brands of cars, and are of the best quality.

In addition to mineral lubricants of the format Rexol TM-5-18, Norsi and Lukoil TM-5-18, there are masses that are not so thick - Wells TM, Spectrol-Forward, Tekso Geartex EP-C. Also on store shelves you can find synthetic and semi-synthetic lubricants for Motulgear, Teboil EP, BP Energear SGX gearboxes.

Oil of the best viscosity for the VAZ-2114 gearbox

In Russia, owners of VAZ-2114 buy off-season liquid well:

When choosing oil, give preference to foreign manufacturers - they rarely cause synchronizer wear at a rapid pace.

What kind of oil VAZ-2114 owners should stay away from is high-viscosity fluids 85W-90. The higher the viscosity index, the stronger the oil film is formed, which means that the lubricant is harder to reach the gearbox components and causes the synchronizers to literally wear out.

The best manufacturer of filling for VAZ-2114 gearbox

• Lada Trans KP;
• Lukoil TM 4-12;
• Nordix Supertrans RHS;
• Slavneft TM-4.

If you trust more expensive oil brands, then pay attention to those that have good reviews from car enthusiasts:

• Castrol 75w90;
• Shell Getribeoil EP 75w90;
• THK 75w90.

There is no point in saving money on deciding what kind of oil to pour into the gearbox for the VAZ-2114 - restoring the lost functionality of the unit is not cheap.

How to correctly fill transmission oil into a VAZ-2114 with your own hands is shown in the following video:

How much to fill

Having understood the quality of the oil, as well as its parameters and the best brands, let’s consider another important parameter - the volume of oil. For the gearbox of the car in question, 3.3 liters of the substance should be filled. This amount of fluid is usually injected after a complete oil change. This procedure is performed as follows:

• Old oil is drained
• The flushing composition is poured
• Flushing is carried out throughout the entire transmission with the engine running.
• The engine is turned off, the new mixture is filled in completely
• Check the level with a dipstick.

All about changing the oil in a VAZ 2115 gearbox: how much oil is needed in the gearbox

The lubricant found in the gearbox decreases in volume during operation and loses its properties, which can lead to rapid wear of parts and complete breakdown of the unit. Let's look at how to check how much oil is in the box of a VAZ 2115 and what is the frequency of its replacement.

Level control and required volume

Oil change process

Many owners of the VAZ-2114 should know that every 70-100 thousand kilometers it is necessary to change the oil in the gearbox.

This is due to the properties of the transmission fluid, which it loses during operation. Transmission oil is designed to lubricate parts and cool heated gearbox elements. It is the temperature difference that becomes the main indicator that affects the loss of quality properties of the liquid, so it must be changed periodically.

Algorithm with photo

The replacement process itself is quite simple and will not pose any problems even for a novice motorist. Let's consider the sequence of actions aimed at replacing transmission fluid in the gearbox:

1. We install the car on an overpass or inspection hole.
2. We wipe the place where the oil level dipstick and drain plug are located.
3. Unscrew the drain plug and wait until the oil drains out completely.
4. We tighten the drain plug. The copper o-ring on the bolt needs to be replaced.
5. Pull out the dipstick from the gearbox.
6. We insert the tube into the hole for the dipstick, and at its other end there is a funnel.
7. Using a funnel, pour oil into the box to the required amount.
8. After changing the fluid, set the dipstick to its normal position.

Oil selection

In the automotive fuel and lubricants market you can find a fairly large number of transmission fluids. Of course, in fact, the VAZ-2114 gearbox can be filled with any one that corresponds to the recommended classification:

1. 75w-90 - synthetic oil for the VAZ-2114 gearbox. It has excellent lubricating characteristics and is capable of ensuring normal operation of the unit at low temperatures. The only drawback is the increased noise during operation of the VAZ-2114 gearbox compared to the use of semi-synthetic lubricant. According to the API classification, the liquid must comply with the GL-4 standard.
2. 85w-90 - semi-synthetic gearbox oil. It has good performance characteristics and is often used in used cars. It is cheaper than “synthetics”. Replacement frequency is every 60,000-70,000 km. API class is also not lower than GL-4.

These are all general characteristics, so let's move on to specifics!

Poll (which oil to choose)

So, let's look at this issue in more detail and write a list of transmission oils that can and should be poured into this unit:

What oil is better to use?

To choose the right fluid for the VAZ 2115 gearbox, you need to take into account the factory recommendations. According to the service documentation, it is necessary to fill the box with special gear oil that meets SAE 80W-85 and API GL-4 or GL-5 approvals. This type of liquid is present in the product range of any company that produces lubricants for cars.

At the factory, when the car is released, TNK or Lukoil brand oil is poured into the box. These same fluids are among those recommended by the manufacturer for the VAZ 2115. When operating a car in winter, many owners try to use synthetic oils that meet the requirements of SAE 75W-80 or 75W-90. The use of such lubricants significantly reduces the operating noise of the unit and facilitates gear shifting at negative air temperatures - below minus 16–18 degrees.

Among the most common oils for the VAZ 2115 are the following (in ascending price):

• Lukoil TM 4–12 80W-85;
• THK Trans KP 80W-85;
• ZIC GF 75W-90;
• Shell Spirax S5 75W-90.

It is strictly prohibited to pour motor oil into a manual gearbox.

Which gear oil is best?

The manufacturer himself gives several recommendations on which substance is best to use for the 2115 gearbox. GL-4 - this should be the API composition group for the VAZ 2115. In addition, the requirements for the viscosity class are given. It also depends on what product is chosen and what needs to be poured.

1. For semi-synthetics, this is the transmission substance 85w90.
2. For mineral: 80w85
3. 75w90t for synthetics

There are several brands that are specifically recommended by the manufacturer for gearboxes. These are TRNAS KP, Slavneft TM-4, Nordix Supertrans RHS, New Trans KP, Lukoil TM 4-12, Lada Trans KP.

It should be noted that in Russia the API GL-4 group itself is classified as TM-4. That’s why the manufacturer recommends using liquid from Lukoil with similar markings. True, this particular composition does not belong to the off-season. Therefore, this liquid will thicken in severe frosts. Because of this, there is a high probability of problems occurring in the operation of the gearbox. Therefore, it is important to decide in advance which product needs to be poured in a particular case.

A separate set of requirements for fuels and lubricants has been in force since 1998. These rules provide temperature ranges within which fluids operate normally. For example, for 80w85 lubricant this temperature is from -26 to 40 degrees. Therefore, for our country it is recommended to give preference to off-season compounds, which are designated as SAE 75W80 or 75W90. Their upper temperature limit is the same, and the lower one reaches -35. This should be taken into account by those who are thinking about which substance to choose.

How to change it yourself?

The design of the components of the VAZ 2115 car is very simple, so the oil in the box is often changed on its own. To do this you will need tools and no more than two hours of time.

Tools and materials

• fresh oil, 3.5 liters is enough;
• rags and gloves;
• 10 and 17 mm wrench (ideally you need a full set, as the protection may need to be removed);
• slotted screwdriver;
• funnel or transmission syringe;
• a container with a volume of at least 4 liters for draining waste.

Stages of work

Immediately before changing the oil in the gearbox, it is necessary to warm it up. To do this, it is enough to drive about 10–15 kilometers.

In order to replace the lubricant in a VAZ 2115 car, you need to do the following:

1. Place the machine on a horizontal surface. It is more convenient to carry out replacement from a hole in the garage or on a lift.
2. Remove the protection of the engine trays and/or transmission. The protection does not need to be dismantled if it has a hole that exactly matches the drain plug.
3. Wipe the lid and box housing around it with a rag.
4. Check for oil leaks along the parting lines and seals.
5. Place the container and unscrew the cap.
6. Wait about 20 minutes for the oil to drain completely.
7. Screw the cover onto the gearbox housing.
8. Lubricant can be filled using a syringe for transmission fluids or a funnel with an extension. In the second case, it is necessary to remove the air filter housing; the device is held on by two clamps - the throttle assembly and the crankcase ventilation tube. Since the VAZ 2115 uses an injection engine, when removing the filter it is necessary to disconnect the air flow sensor connector. Some owners remove the absorber tank to make access easier.
9. Then you need to remove the dipstick from the hole that will serve as the oil filler neck.
10. Pour 2.8-2.9 liters of oil using a funnel or syringe. When changing the lubricant, a smaller volume of liquid is always poured into the crankcase than the rated capacity of the box. This is due to the fact that some old oil remains inside.
11. Wait a few minutes and check the amount of fluid on the dipstick. If the level is below o, the oil must be added. Excess lubricant can be pumped out with a medical syringe with a volume of 50 ml or more with a dropper tube attached to the nozzle.
12. After this, you need to check that there are no lubricant leaks through the drain plug and box components. If traces of a leak are noticeable, then the cause of its occurrence must be eliminated.
13. If the lubricant was replaced while the filter was removed, the parts should be reassembled in the reverse order.
14. After 500-700 km, it is necessary to perform a control check of the oil level and the tightness of the unit components.

In the video, user Denis Onishchenko demonstrates the procedure for changing the oil and removing the car's absorber.

In addition to the video demonstrating the process of changing the lubricant in the VAZ 2115 gearbox, we will describe the sequence of actions.

1. Using a knife, we cut off the side of the container or bottle, creating a kind of “bathtub”.
2. Before starting work, we must warm up the gearbox by driving about 10 km to a VAZ 2115 with a warm engine. In this case, the gears will be able to distribute the lubricant throughout the gearbox.
3. We jack up the right side of the car, place a bar or support, and we lower the car. Under no circumstances should you work under a vehicle that is supported only by a jack.
4. In the case of a cold floor, we place a plywood sheet under the VAZ 2115.
5. Putting on gloves and taking a canister and a 17mm wrench, we go under the car. If the crankcase guard is accessible, it may have a cut under the oil plug. The fork itself is located at the bottom of the left gearbox flange.
6. If there is no cut, the engine protection must be removed. To do this, rub the stopper with a brush and wipe the surrounding area with a cloth, then use a 17mm wrench to unscrew the stopper, placing a canister with warm liquid flowing into the bottom.
7. After waiting 10-15 minutes for the lubricant to be completely used up, we install the plug in place.
8. Using a knife, cut the bottom of a 1.5 liter plastic bottle.
9. Remove the intake pipe and air filter by removing the terminal from the DMRV. We then twist the tags into the crankcase and throttle body to completely remove the inlet assembly.
10. We remove the oil dipstick in the gearbox, located in the upper part, near the passenger compartment.
11. The neck of the bottle without a bottom fits into the hole under the cork, resulting in the bottle serving as a funnel. she needs to pour out no more than three liters of oil, after which within ten minutes we check for lubricant leakage from the fork.
12. If the fluid does not flow out of the fork, install the engine protection in place and remove the VAZ 2115 from the stand.
13. Using the dipstick, continue to fill the transmission oil to the maximum line. The gearbox should contain 3.2 liters of oil.
14. In reverse order from above, we return the filter and input connection.

At first, it is recommended to fill no more than 2 liters of oil. Next, check for leaks in the drain plug under the car. To do this, wait about ten minutes and then continue adding lubricant.

How to choose and change the oil in the gearbox of a VAZ-2115 car

Many car enthusiasts believe that when changing the oil in the gearbox of a VAZ-2115, you should pour, as in all other situations, a special transmission fluid. But it is not so. Some front-wheel drive cars are equipped with gearboxes that are combined with the main gear. The manufacturer recommends using motor oils in them. They have spur gears, which means there is minimal risk of scuffing. There is nothing complicated in the replacement procedure itself. You should be guided by the mileage, condition of the car and its reaction to changing gears with the gearshift knob.

Replacement frequency

If we take into account the official regulations of AvtoVAZ, then on the gearboxes of their model “2115” the oil in the box should be changed every 60 thousand kilometers traveled. Or once every 4 years, if the car has not covered the specified distance. The information presented is completely true. Only in case of increased loads during vehicle operation is it necessary to reduce the frequency. AvtoVAZ perfectly understands the real conditions in which cars have to be. Therefore, it focuses on the poor condition of roads, climate and quality of fuel being poured, which also affects gearboxes.

If the gearbox wears out more intensely, which usually happens when the vehicle is operated under increased loads and in harsh climates, then reduce the replacement period to 40 - 50 thousand kilometers. When selecting transmission oil, pay special attention to temperature indicators. Timely replacement of the oil in the gearbox on a VAZ-2115 car will extend its service life, prevent premature wear and serious breakdowns.

Replacement Regulations

The AvtoVAZ company recommends changing the oil in the VAZ-2115 gearbox every 70 thousand kilometers. A longer service interval can greatly affect the reliability of the gearbox due to its design features. Moreover, it is advisable to replace it earlier than after 70 thousand. This is due to the following risk factors:

• How often should you change engine oil?
• Oil 5w30 and 5w40 what is the difference
• What oil to pour into the engine in winter and summer
• How long does it take to change the automatic transmission oil?

Oil selection

The cylindrical gears used in VAZ-2115 gearboxes are unpretentious in terms of the type of oil selected. Therefore, the transmission will feel equally good when filled with a mineral and synthetic composition. To save money, buy mineral water. The main selection criteria will be:

• relative slip speed indicators;
• parameters of specific loads acting on internal mechanisms.

Here you will need a liquid with a certain viscosity and additives. Make sure it contains anti-seize additives. They will create a special thin coating on the surfaces of rubbing parts, preventing scuffing and reducing overall wear. For the VAZ-2115, transmission compounds of 2 groups can be used:

What should you pay attention to?

The gears in the VAZ 2115 gearbox work equally well in both synthetic and mineral lubricants. Here it would be advisable to be guided by economic considerations and use mineral oil, which is much cheaper.

The main criteria that apply to it can be called:

• Specific load on the internal mechanism;
• Relative sliding speed provided by oil.

It will be important to pay attention not only to the kinetic viscosity of the oil, but also to the additives contained in its composition. They are different, but for a VAZ gearbox it is important to choose a lubricant in which sulfur compounds will predominate. Thanks to them, you don’t have to worry about the formation of “scoring”, since the additive changes the chemical structure on the surface of metal parts. And the film covering them prevents the surfaces from quickly deteriorating.

Level and top up

As the vehicle is used, all fluids are gradually consumed. In the case of a transmission, this does not happen as quickly as with gasoline or oil in the gearbox. But you definitely need to monitor the level. The gearbox of VAZ-2115 vehicles has a special dipstick, access to which is provided through the engine compartment. To make your task easier, you can remove the air filter housing. It gets in the way a little. Manipulations for checking the level are elementary and correspond to the principle of monitoring fluid in the engine crankcase. You need to remove the dipstick, wipe it dry with a rag, insert it back and pull it out again. By the location of the oil film on the dipstick, you will see at what level the fluid is now.

If your version of the gearbox does not have a dipstick, which is typical for old-style gearboxes, you will have to use your eye and fill it to the level of the filler neck. This ensures the right amount of lubrication in the transmission housing. The VAZ-2115 gearbox has its own design features that do not allow it to operate for a long time if the level of transmission oil is insufficiently high. It's all about one gear. It is located higher than the others, which is why when the amount of oil is reduced, the lubricant does not reach it. This gear is responsible for 5th gear. Therefore, be sure to periodically check and add oil. Topping up is carried out through the filler hole from the engine compartment. Maintain a consistently high oil level in the gearbox of your VAZ-2115 so that the box works without crunching and can last as long as possible.

As you can see, it is not difficult to figure out how to check the oil level in the gearbox. In this regard, the VAZ-2115 designers did a good job, since car owners themselves can carry out a number of simple and fairly important repair and maintenance work with their own hands.

Tools and materials

When preparing materials and tools, it is important to consider what type of gearbox is installed on your vehicle. There are two types of gearboxes provided on the fifteenth model from AvtoVAZ. These are old and new style boxes. They are not very different from each other from the perspective of an ordinary car owner. There is no need to go into any minor design or technical differences. The main thing is to understand that on old boxes there is no dipstick and the filler hole is located lower. New transmissions are filled with lubricant using a funnel, but for older transmissions you will need a large syringe and a hose to reach the filler neck. Otherwise, the procedure for changing the working fluid on the two types of gearboxes is identical.

Replacement procedure

To change the oil in the VAZ-2115 gearbox, you have everything ready. Therefore, you can safely begin this procedure. The presented instructions for changing the oil will make you clearly understand that there is nothing complicated here. All work can be easily done with your own hands without outside help. If you do not want to take risks or are afraid to service the transmission yourself for the first time, it is better to trust trusted people from a good car service center. But practice shows that the vast majority of car owners do well in garage conditions. Therefore, do not be afraid, but start working.

To change the working fluid in the gearbox, it is better to have an overpass or inspection hole at your disposal. Many garages have it, so there shouldn’t be any problems with access to the bottom of the car.

1. Place the car on a flat horizontal area. Pre-warm the gearbox and engine to operating temperature. This will allow the oil to drain faster and in greater volume. Stop the engine and remove the negative terminal from the battery.
2. You need to drain the old oil from the box of your VAZ-2115. It’s not difficult to figure out how to drain the waste. To do this, remove the engine crankcase protection, if you have one. The gearbox housing is located approximately under the front wheels, where the engine crankcase ends.
3. About 15 minutes should pass from the moment the engine stops. This will allow the transmission lubricant to drain down.
4. Using a size 17 wrench, unscrew the drain plug. Keep an empty container next to you where the waste will be drained. When the plug is removed, lubricant will begin to flow out of the hole. Act carefully so that the composition does not get on your skin or spill on the floor. Leave a container under the crankcase to allow as much oil as possible to drain from the transmission housing.

5. In total, it takes from 10 to 15 minutes to drain the waste if you have pre-warmed the machine. If not, then the composition may drip for a very long time.
6. When all the waste has come out, return the plug to its place. Make sure that it is not deformed and maintains its sealing properties. Otherwise, the plug will have to be replaced with a new one.
7. Insert a funnel or hose into the filler hole where the dipstick or plug is located, depending on the type of gearbox. If the box is old, then connect the hose to the syringe and start injecting lubricant into the crankcase. Typically this includes about 3.3 liters of fresh transmission fluid. You are unlikely to be able to fill in more than you need, since all the excess will begin to flow back out.

8. Raise the front of the car with a jack. This way you can pour a little more lubricant into the box, where the dipstick is missing and you have to navigate along the neck. The transmission will not suffer from an excess of the composition, but if there is a shortage of lubricating fluid, problems with 5th gear will constantly arise.

If you go by the dipstick, then for the VAZ-2115 it is optimal when the level is 4 - 5 millimeters above the o. After all the procedures performed, when the drained liquid has already cooled down, be sure to check its sediment. If there are problems with the gearbox, which the car owner may not be aware of due to the still normal behavior of the transmission, metal shavings are found in the sediment. This is a dangerous sign indicating excessive wear of the elements. As a preventative measure, special additives can be used. If the problem is too serious and the chips appear again during the next service, it makes sense to contact a car service center to disassemble and repair the unit.
