What boxes are installed?
For a long time, the Toyota concern purchased from Aisin the classic and simplest models, which remained in their arsenal for a long time, while constantly being modernized. Some of the most popular, durable and reliable gearboxes are considered to be A140, A340, A40. They work great and are durable, but this does not mean that they will not need repairs.
Repairing a Toyota automatic transmission, in this case, is not difficult if you compare it with the repair of modern electronic boxes.
Typical problems with automatic transmission Camry 40 with a 2.4 liter engine
During operation, the car owner can expect the following malfunctions of the automatic gearbox:
- Failure of the clutch lock. When replacing it, it is recommended to inspect all elements of the torque converter.
- Appearance of a burnt smell or transmission oil. In this case, it is recommended to change all rubber seals and seals.
Repair kit for seals and seals
- Excessive wear of clutches. It especially often occurs during slippage. The clutches of the Overdrive package burn out first. If this process is not noticed in time, Direct clutches begin to burn.
- If the quality of gear shifting deteriorates, a set of rubber-coated pistons will require replacement. An indirect sign of the need for replacement is a burnt smell of oil.
Rubber coated pistons
- Wear and destruction of the needle bearing located in the rear cover often occurs. This breakdown manifests itself in shocks when switching between second and third gears. Also, if the bearing is damaged, there is a significant delay when moving the selector to reverse mode. Long-term use of a Camry with this defect leads to destruction of the rear cover.
- Many car owners are faced with a leaking pump seal. The root cause of this is overheating of the torque converter and burning of the clutches. It is advisable to replace the oil seal simultaneously with the pump bushing. If repairs are not carried out on time, damage will appear on the pump cover itself and its gears. Further operation of the Camry 40 will lead to wear of all friction surfaces of the automatic transmission as a result of oil starvation.

Problems often arise with the valve body. The solenoids cannot cope with the tasks set by the control side. Overheating of the slab, changes in its geometry, or clogging of channels also often occur.

Review of typical problems with Camry 40 automatic transmission with 3.5L engine
The gearbox, which is installed with a 3.5-liter engine, operates in much more severe conditions. Therefore, its failure occurs much more often. Typical problems encountered with automatic transmissions are shown below:
Excessive wear or burning of clutches. Most often, this trouble awaits owners who love a dynamic driving style and slipping. The appearance of a burnt oil smell requires replacing not only the damaged one, but also entire clutches. This is due to the fact that when the transmission fluid is “burnt,” the surfaces become saturated. As a result, the clutches begin to work abnormally. They slip worse and do not cool as well. The control unit detects this and supplies increased pressure to the valve body and solenoids. Overloading leads to excessive wear.
- The situation when the u660 is jammed occurs quite often. The torque converter hub can become quite hot during slippage. Because of this, it is welded to the bushing. After the automatic transmission has completely jammed, the car owner has to carry out a complete inspection of the torque converter.
- The current pump seal is found on the u660. In the most advanced cases, this leads to a major overhaul of the automatic transmission.
- There are leaks through the dipstick.
- To prevent overheating, car owners install an additional radiator. This partially saves the situation, but during sporty driving the automatic transmission still operates in severe thermal conditions.
- Car owners who loaded the automatic transmission when cold usually experience vibration at 100 thousand km. The reason for this is excessive loads on the retaining ring, which arise under the influence of the lateral load of the transmission of force from the gears to the differential.
- Broken sun gears are often found, especially if the car often slips.
Problems often occur in the electrical part. Sensors, solenoids, selector and its backlight fail. The electrical circuit is not highly reliable.
Necessary materials
To ensure that the removal and installation of the automatic transmission takes place without unnecessary fuss, buy all the materials and tools that you will need right away and keep them nearby.

Design and principle of operation of a hydromechanical gearbox
Materials and tools required for removing and installing automatic transmission:
- a set of hexagons, wrenches, ratchet sockets;
- container for draining waste;
- rags or lint-free cloth;
- original oil, repair kit of oil seals and gaskets for future repairs;
- oil filter;
- transmission jack for removal and installation. Without it, you won’t be able to position the machine gun correctly, because you won’t be able to hold 70 kilograms in the air for long.
You will also need those materials that will be used during automatic transmission repair, that is, for the purpose for which you are removing it. You will have to remove the box on some automatic transmission models if you want to change the filter device.
For example, Mitsubishi Lancer 9 automatic machines do not have a filter under the pan. It is inside the box. To get inside you need to disassemble the machine. And to disassemble the automatic transmission, you will have to remove it from the car.
After the tools are prepared, you can begin disassembling the machine.
Review of automatic transmissions that are installed on Camry with 2.4 and 3.5 liter engines
The Camry 40 with a 2.4-liter engine is equipped with a U250E five-speed automatic transmission. In the USA, Australia, as well as cars exported to eastern countries, this box was used for some time with a more powerful 3.5 liter engine.
The U250E inherited many design solutions from earlier U140-U240 automatic transmissions. The main difference from its predecessors is the strengthening of the planetary gears. In general, the boxes have good interchangeability of the main parts.
Camrys with 3.5 liter engines are equipped with a six-speed automatic transmission U660E. Its development was carried out for the front-wheel drive Lexus ES ES350. The design turned out to be reliable and economical, so Toyota Motor Corporation engineers decided to use this gearbox for the Camry 40.
The U660E box has a lot of childhood problems. Since it has to work in tandem with a powerful 3.5 liter engine, its premature failures are no exception. Automatic transmissions often overheat, clutches burn out, and transmission oil rarely retains its properties from replacement to replacement. A special feature is the standard handle, since the manufacturer used selector illumination.
The upgraded U660E was named U760E, but it was not distributed on the Camry 40. This is due to the fact that the U760E could not cope with the torque produced by the 3.5-liter engine. At the moment, the U760E is used with power units up to 2.7 liters.
Box operating modes
The automatic transmission model and control method (hydraulics, electronics) determine the set of its operating modes. Regardless of the type of transmission on the Camry, there are several main modes:
- P – parking mode. It should be chosen when parking for a long time. The gearbox is turned off, the shaft is blocked, and the drive wheels do not rotate.
Important: you cannot switch to this mode until it stops completely. Also, when stopping on uphill/downhill slopes, you should first tighten the handbrake, and only then put the box into parking mode.
- R – reverse gear. You can transfer to it from “parking” and “neutral” only after stopping the car.
- N – neutral mode. The box does not transmit torque to the wheels, but the shaft is not blocked and the drive axles can rotate. In this mode, the car can be towed over a short (important!) distance.
- 2 – movement is blocked in gears above 2. This gearbox mode is suitable for bad roads, frequent ascents and descents, since it uses engine braking.
- L – low gear. It is recommended to use it on steep slopes and off-road; in it, Toyota moves only in 1 transmission stage.
- D – main mode of the box, forward movement.
There may also be additional buttons on the lever - Overdrive (O/D), SNOW, PWR, MANU, NORM.
- NORM/PWR – switches transmission modes from normal to sports. In the second, the gear shift logic changes, the car becomes more dynamic, but consumes more fuel.
- SNOW – “winter” mode, in which the car starts from 2nd gear, making it easier to start driving on ice and snow.
- MANU button – found mainly on Toyota, similar to Snow.
- Overdrive – permission to use overdrive. When overdrive is active, the car is allowed to switch to the last gear (5, 6...); when overdrive is disabled, it is not. Many people recommend turning off overdrive in the city cycle to increase the service life of the box.

Automatic transmission - removal and installation. Models with four-wheel drive (4WD)
Attention! Gasoline is extremely flammable (as is diesel, although to a lesser extent), so extreme caution should be used when working on the fuel system. Do not smoke or expose the system to open flames or strong incandescent lamps. Do not work in a garage that is heated by systems that use open flames. Since gasoline is a carcinogenic liquid, wear latex gloves when working with it; If gasoline gets on your skin, wash it off immediately with plenty of soap and water. Wipe spilled fuel immediately with a rag, which should not be stored where it could catch fire. The fuel system is under constant pressure, so the pressure must be relieved before disconnecting any hoses or tubes. When performing any work on the fuel system, wear safety glasses and keep a working and valid fire extinguisher on hand.
Attention! The air conditioner refrigerant circuit is under high pressure. If there is a need to open it (disconnect any fittings or pipes), contact a specialized workshop or dealer car service: a specialist should remove the refrigerant from the system.
Note. Removing the transmission in models with four-wheel drive (4WD) is quite a difficult job, especially for a non-professional working in his garage. Based on the design features of the car, the manufacturer prescribes removing the engine together with the gearbox assembly from the bottom of the car (but not from the top). A jack and safety stands alone are not enough - the car will need to be raised quite high. This requires a two-post car lift and a height-adjustable stand-bed for the power unit - these are the manufacturer’s recommendations.
30. Disconnect the cable from the negative terminal of the battery. Remove the hood (see Chapter 11).
31. Referring to Chapter 2D, read the Engine Removal and Installation section for preliminary engine removal procedures, such as disconnecting electrical connectors, control cables, and hoses. Make sure that all wires and hoses are disconnected from the automatic transmission and engine at the top.
32. Loosen the hub/drive shaft nuts (see chapter
and wheel nuts. Remove the wheels.
33. Raise the car with a lift.
34. Remove the lower engine guard(s).
35. Disconnect the selector cable from the automatic transmission (see paragraph 5).
How we are working?
The first thing that is necessary when your Toyota Camry XV40 arrives for service is diagnostics. Diagnostics allows you to determine the source of the problem and choose ways to eliminate it. Most often, it is carried out in three ways: using special equipment that reads error information from the on-board computer, then by an on-the-go test drive and, finally, by visual inspection during partial or complete dismantling of the problem unit.
Having determined the cause of the problem, our technicians install the necessary spare parts and work to restore the machine’s functionality, as well as their cost. If you agree to our conditions, the machine is accepted for work. Our technicians promptly eliminate all identified problems. After that, the car is checked once again. Only if no problems are identified in its operation, our employees will hand over to you a fully functional car, which also has a Camry 40 body in perfect technical condition.
Checking the level
In the Toyota Camry V50, the automatic transmission lubrication level is checked by draining excess oil through an overflow flask located in the pan. Therefore, first add fresh ATF without starting the engine, and then adjust the level. We will fill the machine through the filler hole in the pan:
Now you need to warm up the oil, because as the temperature increases, it expands . To monitor the temperature, use a scanner or SST tool (09843-18040):
Set the oil level to normal:
- Raise the Toyota Camry.
- Remove the stopper of the overflow flask. Be careful, the liquid is hot!
- Wait until the excess drains out and the ATF begins to drip.
- If liquid does not flow out of the overflow flask, add lubricants until it flows out of the overflow flask.
After setting the level, tighten the control flask plug with a new gasket and a force of 40 Nm. The tightening torque of the filler hole is 49 Nm. Lower the Toyota Camry. Turn off the engine. Put the boot back in place.
