What kind of oil is in the automatic transmission of Toyota Corolla 120. Correct oil change in automatic transmission in Toyota Corolla. Consequences of untimely replacement

Good day to all! Today I decided to post detailed instructions on changing the oil in an automatic transmission Toyota Corolla 120. This car It is very common among us, so this information will be very relevant and useful. So, let's start with the fact that the oil in the Toyota Corolla automatic transmission should be changed at least once every 50,000 km. This is not an official requirement of the Toyota concern, but only the optimal recommendation for cars used in Russian realities.

The fact is that all the requirements for replacing consumables described in the car manual are not designed for the Russian climate. Our fuel is worse, the climate is more severe, and road surface leaves much to be desired. Therefore, you should not use Toyota’s recommendations as clear instructions for action. Do you agree that nothing bad will happen if you change the oil in the Toyota Corolla 120 automatic transmission a little earlier? As they say, you can't ruin a Toyota with oil. Or what is it like? I am used to carrying out complete maintenance right away, so I immediately replace the spark plugs on my Toyota Corolla.

What do you need to change the oil in a Toyota Corolla 120 automatic transmission yourself?

This is not oil for a Toyota Corolla robot, where you can get away with two liters. More will be needed here. 🙂

3. Torque wrench. Of course, if it is not there, then you can do without it. However, it is much more convenient with it.

5. Carburetor solvent or cleaner. You can take the cheapest one. There is no difference.

7. Extension hose. We select one so that on one side it fits onto the spout of the funnel, and on the other, it fits into the hole of the automatic transmission dipstick. You can be creative and use adapters.

8. Transparent hose with a diameter of 8-10 mm. We will need it to control the purity of the oil. More on this below.

9. Assistant. You can do it alone, but extra hands certainly won’t hurt.

10. Automatic transmission pan gasket.

11. Lint-free rag, gloves.

12. Container for processing.

5. Use a flat-head screwdriver to disconnect the pan from the automatic transmission housing and drain the remaining oil into a container. We move the pallet to the side.

9. Clean the automatic transmission pan from dirt using carburetor cleaner. Pay special attention to the magnets installed on the pallet.

10. Reinstall the automatic transmission pan. Be sure to use a new gasket. We tighten the bolts with a force of 5 Nm. The joints must first be degreased. You can also use a thin layer of sealant.

When should you change your oil?

Manufacturers modern cars It is often claimed that the lubricant poured into the gearbox housing at the factory does not need to be changed throughout its entire service life. Toyota Corolla should be replaced according to the manufacturer's recommendations every 160 thousand km. But real vehicle operating conditions reduce the service life of the fluid several times, so it is advisable to change the lubricant after 40–60 thousand km. In addition, the main sign of the need to replace the fluid in the box is its darkening, accompanied by the appearance of a characteristic odor.

Selecting oil and filter

The manufacturer fills gearboxes with JWS3309 and Type T-IV (or T4) approved oil. When purchasing a replacement lubricant, you need to choose a liquid that corresponds to exactly these parameters. Original Toyota Genuine ATF WS oil (order number 08886–02305) is supplied in plastic cans with a capacity of 0.946 liters or in four-liter tin cans.

Original Toyota Genuine ATF WS oil

Total Fluide XLD FE oil, as well as Castrol Transmax Dex VI Mercon LV, can be a good alternative to the original lubricant. However, Toyota recommends using only its own oil for replacement. Analogues can be used to refill automatic transmissions of older Corolla models with a 110 body, designed for the use of lubricants with a lower tolerance - D-III.

The video, shot by Vladimir Pyanykh, shows the process of changing the oil on a Toyota Corolla 110.

When changing the lubricant, a new oil filter must be installed. For Corolla E150 2010 and 2012 models, the original device with catalog number 35330–0W020 is used. The same filter was used on the earlier Toyota Corolla E120 2007 model. There are many analogues of such filter elements, for example, JS Asakashi JT425K or SAT ST353300W020, as well as a number of others.

On right-hand drive versions of Toyota Corolla Spasio and Fielder, the original filter 35330-0W021 or its analogue JS Asakashi JT425K is used.

Level control and required volume

During operation Toyota car Corolla should carry out timely monitoring of the oil level in the box.

On new car It is necessary to control the amount of lubricant after 50 thousand kilometers. On cars older than five years, the inspection frequency is every 20 thousand kilometers traveled or once a year.

Corollas can be checked using a special dipstick installed in the transmission housing. When the engine is cold, the amount of lubricant should not be below the “COLD” mark on the dipstick rod. After the box has completely warmed up, without turning off the engine, you need to make sure that the amount of fluid is at the “HOT” mark. If the oil volume is insufficient, it is necessary to add it and find out the reason for the decrease.

Probe rod with marks

Full filling capacity Toyota car boxes depend on the country where the cars are delivered. Four-speed automatic transmissions Corolla 120 and 150 for European regions hold 3.8–4.0 liters of lubricant. Cars for the Japanese domestic market - Spasio and Fielder are equipped with all-wheel drive, so their gearbox crankcases are more capacious and hold about 8 liters of fluid.

Oil change options

There are several types of oil changes in Toyota Corolla automatic transmissions, which differ in complexity:

1. The simplest operation is partial replacement lubrication, which does not involve installing a new oil filter. In this case, the liquid located in the oil pan of the box is drained through a special hole, which is closed with a screw plug. Fresh grease is added through the dipstick hole. When making such a replacement, you need to know exactly the type of oil previously poured into the automatic transmission, since mixing fluids with different tolerances is prohibited.
2. A more complex process is complete replacement oil, which is produced in specialized centers for repair and maintenance of automatic transmissions. During this procedure, the old oil is washed out with new oil supplied under pressure. In this case, up to 12 liters of ATF fluid will be required to change the lubricant. This operation is carried out without changing the filter and is therefore risky, especially on transmissions with high mileage. Since the dirt and wear products contained in the waste fluid will clog the filter and spread throughout the transmission. How the box will behave and how long it will last after such a replacement is unknown.
3. The third option is most preferable for Corolla automatic transmissions with any mileage. It consists of a complete oil change with removal of the pan, which allows you to install a new oil filter instead of the old one, in which a significant amount of dirt accumulates. Another advantage of this method, unlike others, is the ability to wash the inside of the pan and magnets from wear particles.

How to change it yourself?

Removing the pan is a fairly simple operation that you can do yourself.

When performing work, it is necessary to take into account that machines for the European and Japanese markets are equipped with gearboxes that differ in design and crankcase volume.

On European Corollas 120 and 150, the gearbox design is simple, and the replacement process is therefore simple. And in the Toyota Spasio car, which is a version of the Corolla 120 with right-hand drive, as well as the Toyota Fielder 121, it is installed four-wheel drive. Therefore, when changing the oil in these cars, it is important not to confuse the transmission pan with a similar part of the transfer case.

Tools and materials

To change the oil you will need:

• • oil - 4 liters for left-hand drive cars and 8 liters for right-hand drive cars;
  • filter device;
  • filter gasket;
  • new drain plug gasket;
  • stable, wide container with a volume of at least 5 liters for collecting used oil;
  • a funnel with a thin spout or rubber hose for pouring new lubricant;
  • set of keys and sockets;
  • a narrow wooden wedge for removing the pallet;
  • approximately 1 liter of gasoline to clean the outside of the box tray;
  • rags and gloves.

In the video shot by user Maxim Denisov, you can see how the oil is changed in a Toyota Corolla 120 automatic transmission.

Algorithm of actions

Before starting the procedure, the car must be warmed up to operating temperature and placed on a lift or inspection hole in the garage.

The procedure for changing the oil in the gearbox of a 2008 Toyota Corolla is as follows:

1. You need to unscrew the drain plug and drain the oil from the pan.
2. After draining the main part of the liquid, it is necessary to loosen the 19 10 mm bolts securing the pan.
3. Then you should unscrew all the bolts, except for any two located oppositely.
4. You need to insert the tip of a wooden wedge into the gap between the pan and the crankcase and disconnect the parts from each other. It is important not to damage the sealing gasket.
5. Unscrew the last two bolts and carefully remove the pan, tilting it to the side to drain the remaining oil as much as possible.
6. After this, you need to unscrew the magnetic cover of the differential box and drain the lubricant from there.
7. Wash the pan and plugs with gasoline, paying special attention to the chip-collecting magnets installed on the pan body.
8. You need to unscrew the three 10 mm bolts securing the filter and replace the device. It must be remembered that it contains a certain amount of oil. The tightening of the filter bolts should be no more than 10 Nm.
9. The box should be assembled in reverse order. The pallet bolts must be tightened crosswise, ensuring an even fit of the parts. At the same time, they should not be overtightened (torque no more than 8 Nm), since the body and pan gasket are very easily deformed. The tightening torque for the drain plug is 49 Nm.
10. New oil must be poured through the hole for the dipstick in an amount of no more than 3.5 liters. In this case, it is necessary to check that there are no leaks through the plugs and the pan gasket. Then warm up the car and once again make sure there are no leaks.
11. On a warm box, it is necessary to move the gear selector to all positions, holding it in each position for about 10–20 seconds. The car does not move. Perform these steps three times.
12. Then you need to park the car on a level surface and measure the oil level, which should correspond to the “HOT” mark on the dipstick. Volume deviations up or down are unacceptable. If there is not enough oil, it must be added. In case of excess lubricant, it is convenient to use a regular medical syringe of maximum volume to drain it. You need to put a long tube on it, which should be lowered into the hole for the dipstick.

When changing the oil in the crankcase of a Toyota Corolla automatic transmission, a certain amount of old lubricant remains. Therefore, if the car has a long mileage, then after 1 thousand kilometers traveled after the replacement, you can additionally partially change the fluid. This procedure will increase the percentage of new oil in the box and will remove accumulated wear products that can settle in various places in the automatic transmission crankcase.

Algorithm of actions when changing the oil in right-hand drive cars

Right-hand drive Toyota Corolla Fielder and Spasio cars are equipped with a separate radiator for cooling the lubricant. When changing the oil in the sump, the liquid from the radiator is not drained, since there are special valves in the pipeline design. Since the volume of lubricant in the radiator is comparable to the amount in the pan, it must be drained and replaced with a new one. This procedure will require the help of one more person.

The sequence of actions is as follows:

1. Remove the oil drain hose from the radiator, extend it to a length that allows it to be brought into the engine compartment.
2. The free end of the hose must be placed in an empty container with a volume of at least 4 liters.
3. After this, the assistant must start the engine.
4. Used lubricant will begin to flow out of the hose; at the same time, fresh oil must be poured into the hole for the dipstick.
5. At the end of the procedure, almost 4 liters of liquid will come out of the radiator, and the same amount should be poured into the crankcase.

The amount of fluid when filling is controlled by marks on the dipstick in a warm box and with the engine running. The filter is installed, the automatic transmission is ready to be filled with oil.

Price issue

Price self-replacement oil depends on the type of vehicle gearbox, type of consumables and point of sale. Automatic transmission oil will cost the buyer about 3,100 rubles. - original and approximately 1500 rubles. - analogue. An automatic transmission filter is priced from 400 rubles. for the simplest analogue up to 2800 rubles. for the original part. The cost of installing a drain plug is 50 rubles. The filter gasket costs 120 rubles. In total, replacing the fluid on a Toyota Corolla 120 and 150 will cost the car owner from 2,070 to 5,950 rubles.

Toyota Corolla Spasio and Fielder cars require 8 liters of oil to change, which increases the cost of the procedure from 3,570 to 9,050 rubles. A pan gasket damaged during the procedure can add about another 500 rubles to this amount. But in any case, the cost of purchasing consumables will be lower than the cost of repairing a failed automatic transmission.

Consequences of untimely replacement

Aged oil has a negative effect on automatic transmission components. Moreover, each problem becomes the cause of another, more critical and requiring expensive repairs.

Below is an approximate algorithm for complete failure of the gearbox in case of untimely replacement of transmission oil:

• the first thing the owner will encounter is shocks and jerks when switching;
• then the hydraulic accumulators in the box fail;
• after this, burning and chipping of the friction clutches begins;
• an increasing number of mechanical impurities completely clog the filter and it stops performing its functions;
• Because of this, mechanical particles get into the bearings and valves of the valve body, which leads to emergency operating modes of the automatic transmission and complete immobilization of the vehicle.

Toyota Corolla 120 is a common car in Russia, in high demand for secondary market. Russians highly value the quality and reliability of Japanese products, even despite the expensive maintenance. In fact, you can perform some repair procedures on the Toyota Corolla 120 yourself. For example, this is changing the oil in an automatic transmission. This procedure does not take much time, and is carried out using improvised means - tools and materials, without the use of expensive diagnostic equipment. In this article, we will consider in detail the most important steps when changing the lubricant in a gearbox using the example of a Toyota Corolla 120 with an automatic transmission.

When to change

The optimal interval for changing oil in a Toyota Corolla 120 automatic transmission is 50 thousand km. This is unofficial data that differs significantly from those presented in the instructions. The fact is that the Toyota company advises practically not to change the oil at all - they say that it is supposedly designed for the entire service life of the transmission. This is true, but still depends on operating conditions. For Russia, for example, the oil needs to be changed more often. This will give you more confidence that the factory gearbox will last as long as possible, and then you won’t have to buy a new automatic transmission.

Set of tools and materials for replacement

1. Canister with original Toyota oil, capacity 8 liters
2. Tools including torque wrench
3. Funnel
4. New oil filter
5. Hose – required for connection to the funnel spout (on one side) and the automatic transmission dipstick hole (on the other side)
6. Transparent hose with parameters 8-10 mm in diameter. It is necessary to control the purity of the oil
7. Extra hands won't hurt, so it's advisable to have an assistant
8. Rag, rags, gloves
9. Drain pan for old oil

Sequence of work

1. Warm up the engine and drive the car onto the overpass. The oil should be hot and thinner
2. Turn off the engine, go down into the inspection hole
3. If there is a motor protection, it must be removed to gain access to the automatic transmission housing.
4. Before unscrewing the plug, make sure that a pan is installed under the crankcase to drain dirty oil.
5. The drain plug is unscrewed with a 13mm wrench. Hot oil will pour out of the drain hole, so you need to be careful and wear gloves
6. After draining the used oil, unscrew the transmission pan mounting bolts. A 10mm head is best suited for this. Do not unscrew the remaining 1-2 bolts completely, so that the oil pan does not fall.
7. Take a flat-head screwdriver, disconnect the pan from the gearbox housing, and then drain all remaining oil from the pan into a previously prepared container. Move the transmission pan to the side until we need it
8. Using a 10mm socket, unscrew the three bolts securing the automatic transmission filter
9. To dismantle the filter - to do this you need to pull it down towards you and remove it from its seat
10. Thoroughly clean the seat from dirt deposits, and then install a new oil filter with a gasket. Tighten the filter with a torque wrench to 11 N/m.
11. It is advisable to use carburetor cleaner to clean the transmission pan.
12. Place the pan back in place and use a new gasket. Please note that the bolt attachment points may be greasy (due to oil), so they must be degreased. For greater reliability of bolt fastenings, you can apply a thin layer of sealant
13. Tighten the drain plug with a wrench to 17 N/m
14. Fill with new oil. It is advisable to fill in as much as the old fluid has been drained. To know the exact volume, any measuring cup will do. As a last resort, you can use any identical plastic bottles - the used liquid is poured into one of them, and fresh original oil into the other
15. After filling in new fluid, disconnect the hose connecting the automatic transmission radiator and the automatic transmission housing. Take the prepared transparent hose, put it on a metal tube, and release it into a 1-liter container
16. Give the command to the assistant to start the engine so that it can run for a while. idle speed- until exactly one liter is filled in that same 1-liter container. It is important that clean, light pinkish oil flows out of the hose (at first it will be black and dirty). Please note that this process usually takes 4 liters of oil.
17. When the process is completed, we collect all the parts and put them back in place.
18. Start the engine, switch the gearbox selector to different positions, then switch back to parking mode. Stop the engine and check the oil level using the dipstick. If the fluid is below the Max level, then the oil needs to be added a little.

In order to extend the service life of the automatic transmission of a Toyota Corolla, it is necessary to promptly. Often, when driving, you begin to feel that the transmission is not quite soft, and strange sounds appear when changing gears. During operation, the lubricating fluid loses its properties and does not provide protection for internal mechanisms. Changing the oil in the automatic transmission of a Toyota Corolla 150 can be done in a specialized service center using special equipment or independently in a pit.

To change the oil in a Toyota Corolla automatic transmission, you can choose alternative lubricants.

Replacement frequency

The Toyota Corolla gearbox is highly reliable. Major repairs are performed after approximately 350 - 400 thousand kilometers. The Toyota concern advises changing the gearbox oil after 150 thousand km. or in four years. If the car is operated in difficult climatic conditions with low temperatures, then the service life (frequency) of the Toyota Corolla is reduced several times (40 - 50 thousand km or two years).

What kind of oil to fill

It is best to fill the original oil into the automatic transmission, recommended by the manufacturer: Toyota ATF Type T-IV. You can also choose an analogue of ATF Totachi Type T-IV. If necessary, you can use any from a reliable manufacturer. In addition to the lubricant, it is necessary to replace the oil filter, the drain plug O-ring and the pan gasket.

Oil volume in box

For complete transmission box You will need about 8 liters, but you need to consider how much oil is needed if the procedure is performed independently. The volume in this case is approximately 4 liters. Half will remain in the internals of the automatic transmission. Typically, a complete replacement is carried out when the transmission is repaired and it needs to be disassembled. The driver has the opportunity to check the amount of lubricant in the box. Checking the oil level is done with a special dipstick.

On a cold engine, the value should not be below the “COOL” mark. After warming up the automatic transmission, the lubricant volume indicator should be at the “HOT” mark.

Replacement algorithm

Even a novice driver can cope with this work, because changing the oil in an automatic transmission is quite simple, the main thing is to follow the instructions. Do-it-yourself replacement does not require special equipment. You need to go to a pit or a lift. The procedure takes one to two hours if you have some skill. You need to prepare four liters in advance original oil, filter, gaskets for the filter and drain plug, a container for draining old oil of more than five liters, a set of keys. in Toyota Corolla 120 is carried out as follows:

1. Before Maintenance The automatic transmission needs to warm up the car for ten to fifteen minutes. Next, you should put the car on a pit or lift. Then you need to unscrew the pan plug and wait until the liquid completely drains through the drain hole into the prepared container.
   
2. To remove the automatic transmission pan, unscrew the bolts, leaving the two opposite ones attached. Disconnect the pan gasket. Next, remove the pan completely. This may leave about 400 ml. hot liquid.
   
3. It becomes possible to remove the differential magnetic box. This will add a little more oil. We clean the magnetic plug and magnets with gasoline. Then we wipe them with a dry cloth and carefully return them to their place.
   
4. We also clean the tray. After this, you can install it back, after replacing the gasket. We tighten the bolts diagonally gradually one after another so as not to strip the threads.
   
5. Now you can tighten the drain plug with a new gasket.
6. In the engine compartment we find a hole for the control dipstick. Fill in the same amount of liquid as flowed into the drain container (about 3.5 liters). Overfilling of oil should be avoided. Otherwise you will have to remove the excess with a syringe. It is much easier to add the missing transmission lubricant.
   
7. We start the engine and warm up the automatic transmission. In this case, you should move the switch handle to different modes with a delay of several seconds each. We repeat this operation three times.
8. With the engine running, carefully check the lubricant level. If necessary, add or remove some of the liquid.
9. Don't forget to inspect the transmission pan for leaks. Over-tightening the bolts can cause leaks.

When operating a Toyota Corolla, it is recommended to change the automatic transmission oil after a mileage of 150-160 thousand km. When operating a car in Russian conditions, it is necessary to change the oil after 50 thousand kilometers.

Changing the gearbox oil is possible using 2 options:

• all replacement operations are carried out at the auto center by qualified personnel with the replacement of the filter and other parts, if necessary;
• work on changing the oil in an automatic transmission is carried out by the car owner himself, performing the sequence of operations according to the instructions.

Necessary components for work

To replace the transmission, it is not oil that is used, but a special composition intended specifically for this unit. The container label for this liquid bears the designation ATF (automatic transmission fuid). This liquid is able to function under more difficult conditions, withstanding significant loads. When the gearbox is operating, the operating temperature of the parts reaches 300-400*C.

The torque converter experiences heavy loads: when the car is moving, the temperature of the systems reaches 150*C.

During long-term operation of the gearbox, volatile components evaporate from the solution used for lubrication and cooling, changing the composition transmission fluid, which is unacceptable.

The fluid poured into the Toyota Corolla automatic transmission performs a dual function:

• heat removal from the box parts to the external environment;
• lubrication of contacting parts.

To stabilize the solution at high temperatures and stabilize ongoing processes while preventing oxidation, special additives are added that prevent wear of parts and allow mechanisms to function normally at temperatures from -40* to +150*C.

During long-term operation of the gearbox, volatile components evaporate from the fluid used for lubrication and cooling, and the composition of the transmission fluid changes, which is unacceptable for the normal operation of the mechanisms.
