Oil change in automatic transmission Toyota Corolla

Changing the automatic transmission oil of Toyota Corolla in 120 and 150 bodies is a mandatory and important maintenance step. Transmission fluid loses its working properties over time and is subject to partial or complete renewal. Postponing this procedure or completely abandoning it leads to unpleasant consequences for the Toyota Corolla automatic transmission, the repair of which can cost a huge amount.

Transmission oil change interval

To find out after how many kilometers it is recommended to change the oil in a Toyota Corolla automatic transmission, you need to refer to the manufacturer's instructions.

The recommendations given in the Toyota Corolla instruction manual state that the "transmission" should be updated every 50-60 thousand kilometers.

But these data refer to a car that was operated in ideal conditions: without significant temperature changes, on good roads, etc., our country does not adapt to those conditions.

Experienced motorists say that it is necessary to change the transmission fluid in Toyota Corolla every 40 thousand km. At the same time, it is not recommended to change the total volume of lubricant (about 6,5 liters) using hardware pumping, since the protective film on the mechanism parts will be broken. A partial replacement is welcome, in which half of the volume of fluid is updated and replenished by passing the transmission through a hose from the radiator.

Practical advice on the choice of oil in automatic transmission

Do-it-yourself oil change in an automatic transmission Toyota Corolla 120, 150 body, the choice of consumables must be approached wisely. Additional service of the unit depends on its quality. The choice of the brand of "transmission" must correspond to the modification and year of manufacture of the Japanese. For the Toyota Corolla E120, produced in the period 2000-2006, and the E150 model, which continued to be produced until 2011-2012, it is recommended to purchase different "transmissions".

Particular attention should be paid to the purchase of oil for automatic transmission Toyota Corolla. Even if you plan to update the oil not with your own hands, but with the help of service stations, all the necessary materials should be purchased on your own in trusted stores. Therefore, the risk of buying low-quality products will be significantly reduced.

Original oil

An original transmission is a brand-specific product that has been specifically designed for a given vehicle and is recommended by the manufacturer.

Such an automatic transmission oil for Toyota Corolla 120 is Toyota ATF Type T-IV. For vehicles with a body of 150, it is recommended to use Toyota ATF WC. Both types of fluids are interchangeable and, if necessary, their partial mixing in automatic transmission is allowed.

The prices for the original product are very democratic. The cost of plastic containers with a volume of 1 liter with the code 00279000T4-1 is from 500 to 600 rubles. For a four-liter canister with the article number 08886-01705 or 08886-02305, you will have to pay from 2 to 3 thousand rubles. The variation in prices is due to different manufacturers and different packaging.

Analogues

All original products are copied by other manufacturers and produced under their own brand. Subject to all necessary standards, the resulting analogue is almost no different from the original. But the cost of goods can be significantly reduced. Below are the brands of transmission fluids for automatic transmissions Toyota Corolla 120/150.

Checking the level

Before starting the procedure for updating the transmission on a Toyota Corolla, it is necessary to measure its level. To do this correctly, you need to follow the algorithm of actions:

• drive a car for about 10 kilometers to heat the oil in the Toyota Corolla automatic transmission to operating temperature;
• stop on a flat surface;
• lift the hood and remove the automatic transmission oil dipstick;
• wipe it with a dry cloth and install it in its original place;
• after that, take it out again and check the level at the top mark with the inscription "HOT".

If the transmission fluid level is low, it should be topped up. If the level is exceeded, the excess is pumped out with a syringe and a thin tube.

Materials for a comprehensive oil change in an automatic transmission Toyota Corolla

To change the oil in a Toyota Corolla automatic transmission in 120, 150 bodies without resorting to outside help, you need to be patient and have the necessary list of materials. In time, this can take two to three hours if you have all the tools at hand.

List of required materials:

• transmission fluid 4 liters;
• automatic transmission oil filter catalog number 3533052010 (35330-0W020 for 2007 Toyota Corolla 120 rear models and for 2010 and 2012 150 rear models);
• a set of keys;
• sufficient transmission dump capacity;
• degreaser 1 liter (gasoline, acetone or kerosene);
• new pan gasket (part number 35168-12060);
• drain plug o-ring (pos. 35178-30010);
• sealant (if necessary);
• rags and water to clean dirty surfaces;
• funnel with a narrow end;
• container with a scale for measuring volume;
• protective gloves;
• wrench.

This list is required for a partial oil update in a Toyota Corolla automatic transmission. A full cycle will require at least 8 liters of oil and an additional plastic container, as well as the help of another person who will periodically start the engine. In addition to all this, the event requires a flyover, an observation deck or an elevator to provide convenient access to the Toyota Corolla automatic transmission.

Self-changing oil in automatic transmission

Having prepared all the materials and measured the level of the hot liquid, you can begin to change the oil in the Toyota Corolla automatic transmission. Before starting work, put on thick gloves to avoid burns if hot oil gets on your hands.

Draining old oil

In the box, the Toyota Corolla machine contains as many liters of oil as the working volume of the unit is about 6,5 liters. When unscrewing the drain plug, not all the oil is poured out, but only half. The rest remain in the group. Therefore, it is necessary to prepare such a container for the waste liquid so that about 3,5 liters fit. Most often, a five-liter container with a cut neck is used under water.

To get to the automatic transmission plug on a Toyota Corolla, you need to remove the engine protection. Then, using a 14 key, unscrew the drain plug, after which the transmission will immediately pour. You should try to collect all the oil that comes out, since it is this amount of fresh fluid that will need to be returned.

Pallet rinsing and swarf removal

The box pan plays an important role in the Toyota Corolla automatic transmission - it collects soot, used dirty oil. Magnets mounted on the bottom of the part attract the chips formed as a result of the friction of the mechanisms. To get rid of accumulated dirt, it is necessary to remove the pan and clean it thoroughly.

The lower part of the Toyota Corolla automatic transmission is unscrewed with a 10 key. In order to avoid abrupt removal of the part and not spilling oil on it, it is recommended not to completely unscrew the two bolts diagonally. Use a flat-blade screwdriver to pry the tab on the tray and carefully pry it off the mating surface. After that, you can unscrew the remaining bolts and remove the pan. Contains about half a liter of oil.

We wash the lower part of the automatic transmission with a degreaser. We clean the chip magnets. Then wipe it with a soft, lint-free cloth and set it aside.

Filter replacement

The automatic transmission filter element in the Toyota Corolla needs to be replaced with a new one. Microscopic particles, a product of the transmission fluid, settle on it. The average price of this important part does not exceed 1500 rubles for cars of the first years of production in the back of 120.

For restyled versions of Toyota Corolla, produced from 2010 to 2012, an automatic transmission oil filter is installed when changing the oil, which will cost the car owner 2500 rubles. But even this amount spent will be worth it, since the automatic transmission will work properly and will not cause problems.

Filling in new oil

After installing a new automatic transmission filter element in a Toyota Corolla, it is necessary to mount the pan. To do this, lightly sand the contact surfaces of the part and the housing with sandpaper. For greater confidence in the absence of leaks, a thin layer of sealant can be applied.

We install a new gasket between the surfaces and begin to tighten the bolts, starting with the diagonal ones. Using a torque wrench, we control the force of 5 Nm. Next, the final stage is filling with fresh liquid.

To understand how much oil is required when changing it in a Toyota Corolla 120/150 automatic transmission, it is necessary to measure the total amount of removal. Having measured the same amount of fresh product, insert the funnel into the hole under the cap and slowly begin to pour the liquid.

After the work done, you need to drive a few kilometers, stop and check the level according to the mark on the "HOT" dipstick. At the same time, look under the car to make sure there are no leaks.

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

Changing the oil in a right-hand drive automatic transmission Toyota Corolla has the same procedure as in European ones. Some Corolla models were produced in an all-wheel drive version. When performing the oil change procedure in these vehicles, you must be careful when removing the automatic transmission pan, do not confuse it with the bottom of the transfer case.

Another important difference in the design of the "Japanese" automatic transmission is the presence of a separate cooling radiator, which contains part of the liquid. It is impossible to drain it with a drain plug. This requires a complete oil change.

Complete replacement of transmission fluid in automatic transmission

A complete change involves running oil through the Toyota Corolla radiator return hose. The procedure is carried out in stages, as in the "European", but after filling in a new liquid, the process does not end there. Next, you need to perform the following steps:

• start the engine and, with the brake pedal pressed, switch the automatic transmission lever to different modes;
• turn off the motor;
• disconnect the hose coming from the automatic transmission crankcase to your radiator, and place a 1-1,5 liter container under it;
• ask a partner to start the engine, after filling the bottle, turn off the engine;
• measure the volume of the drained fluid and add the same amount of new fluid into the hole under the hood;
• repeat the procedure for draining and filling the transmission 3-4 times until the outlet fluid matches the color of the purchased one;
• screw the return hose;
• check the oil level on the dipstick.

It should be noted that the transmission fluid with this method of updating will require much more - from 8 to 10 liters. The procedure will also take longer than a partial oil change.

Price issue

To change the oil in an automatic transmission of a Toyota Corolla in the back of 120/150, it is not necessary to seek help from specialists in expensive service centers. Automatic transmission fluid renewal is easy for the average car enthusiast and saves money at the same time.

A partial oil change will cost the owner 4-5 thousand rubles. A full cycle with two or even three canisters of liquid will cost 6-7 thousand.

The total amount of replacement is the sum of the cost of transmission fluid, oil filter, gaskets for Toyota Corolla. Any service station mechanic will take from 3 to 7 thousand rubles for work, depending on the level of the service center and the region.

Conclusion

Changing the automatic transmission oil (automatic transmission) in a Toyota Corolla is a feasible task for most car owners. This approach to car maintenance reduces the likelihood of using low-quality consumables by service center employees.

Timely oil change in Toyota Corolla automatic transmission will prevent problems with the unit and reduce the risk of wear or premature failure.
