MMT box from TOYOTA. Diagnostics, adaptation and repair of robotic gearboxes on the importance of timely repair and maintenance

Toyota Corolla cars have compact dimensions and are equipped with high-quality and modern control systems. This model of vehicle from Japan is in great demand among motorists in most countries of the world. In 1974, the Corolla entered the Guinness Book of Records as the best-selling car in the world. During the existence of vehicles from this line, motorists purchased more than 40 million cars.

Toyota Corolla MMT transmission repair

Toyota Corolla models are equipped with different types of transmissions. The simplest and most comfortable boxes are robotic MMTs. This mechanism automatically adapts to the driver’s driving style and, through a special control unit, selects the optimal gear for driving.

Repairing a MMT Toyota Corolla is an expensive and labor-intensive job that requires not only knowledge and experience, but also special tools and equipment. It is almost impossible to troubleshoot a robotic transmission on your own. Incompetent intervention in the box components most often leads to complication of problems. As a result of such actions, a complete replacement of the mechanism may be necessary.

The Freetronic robotic manual transmission (sometimes called Multimode or simply MMT) has been developed from the traditional manual transmission by adding drives switched by electric motors. By adding an electronic control system, both automatic and manual gear shifting modes became possible.

The photo shows the interior of a Toyota Corolla equipped with an MMT gearbox.

Information about the position of the drives is read by contactless sensors and sent to the control unit (TCM) of the robotic gearbox. Three electric motors take part in the gear shifting process: one is responsible for the clutch (squeezing), the other two are responsible for shifting gears along the X and Y axes.

The only advantage compared to a conventional automatic transmission is the ability to manually change gears using steering wheel paddles and slightly lower (~ 0.5 liters) fuel consumption. At the moment, Toyota does not install this transmission, but it continues to operate in slightly modified form on cars of the Peugeot/Citroen automaker.

The defect on Toyota cars with an MMT robotic transmission manifests itself in the disappearance of assistance when starting from a stop; when gas is added, the car jerks (manifests itself when starting to move and when moving forward and backward). Computer diagnostics may reveal this error (sometimes there are no diagnostic errors at all!):

P0810- general clutch position error

P0900- error in the clutch actuator circuit

The disease is present on cars with MMT transmission control unit numbers ending in “0” or “1” (cars produced before 2008; by the end of 2008, Toyota began installing new units with the number “2” at the end, where the problem was eliminated once and for all ). In 2009, Toyota decided to abandon this transmission in favor of a conventional automatic.

On the Yaris and Echo cars, Toyota for the first time massively used an interesting device - the Freetronic automatic clutch - TFT (Toyota Free-Tronic).

1. General structure.

The TFT-Freetronic drive, based on commands from the MMT unit, controls the amount of fluid pressure supplied to the clutch master cylinder, turning it on and off.
Sensors installed on the gearbox determine the current position of the gearshift lever, and the rotation speed sensor measures the rotation speed of the gearbox input shaft. Limit switches on the lever proactively inform the unit that the driver is about to engage the gearshift lever.
The indicator warns (flashes) that there is a malfunction in the Free-tronic (TFT) system or that the driver is trying to make an incorrect shift (constant light).


2. Drive.

An electrically driven radial piston pump constantly maintains high pressure in the accumulator (diaphragm type with a cavity filled with compressed nitrogen), so that the stored volume is sufficient for several clutch releases.
The pressure in the accumulator branch is controlled by a sensor - when the pressure drops, the unit activates the electric pump, and when the pressure reaches the nominal value again, after a few seconds the unit turns off the electric pump.
To redistribute fluid flows, a spool valve driven by an electromagnet is used. The pressure relief valve bleeds fluid when the pressure is too high.


3. Hydraulics.


The spool valve operates in three modes, corresponding to decreasing, increasing and maintaining pressure in the GCS.


4. Electronics.

5. Operation

· When the engine is turned off, the channel between the drain and the main fluid circulation center is constantly open and the clutch remains engaged.

· Launch. When the ignition is turned on (if the gearshift lever is in neutral), the MMT unit disengages the clutch, after which the engine can be started.

· Start of movement. When the lever is shifted into 1st, 2nd or reverse gear, a corresponding signal is sent to the MMT (Freetronic - TFT) control unit. When you press the accelerator pedal, a throttle position signal is also transmitted to the unit. After this, the block switches the spool valve to pressure reduction mode, engages the clutch and the car starts moving. The position of the spool changes gradually to ensure sufficient smooth engagement of the clutch. When the rotation speed of the crankshaft and the gearbox input shaft are equalized, the block completely opens the main fluid circulation channel to drain and fully engages the clutch.

· Gear shift. When you move the gearshift lever and release the accelerator pedal, the corresponding signals are sent to the MMT control unit, which determines the need to disengage the clutch and connects the hydraulic fluid accumulator channel to the hydraulic accumulator line. After the unit determines the end of the shift (based on the signal from the neutral sensor and the lever limit switches), the clutch is engaged again.

· Stop. When the vehicle is braking and the gearbox input shaft speed drops below the set level, the TFT control unit disengages the clutch.

· At opening the driver's door the corresponding signal is sent to the Freetronic control unit and it activates the electric pump to accumulate fluid pressure in the accumulator.

· If the car is in gear, then after turning on the ignition, pressing the brake pedal and moving the gearshift lever, the Fritronic control unit disengages the clutch, as a result the lever can be easily moved to neutral.

· Buzzer used to warn the driver in certain situations:
- if the engine is running, the lever is set to a position other than neutral and the driver's door is open;
- if there is an error during a downshift (for example, at a fairly high speed after 5th gear, the driver tries to engage 2nd);
- if the driver tries to start the engine while the gear is engaged;
- if the driver tries to start from a gear higher than 3rd;
- when there is excessive load on the clutch (for example, during prolonged operation with the clutch partially engaged);
- if the brake pedal has not been pressed for a set period of time while the gear is engaged.

MMT gearbox TOYOTA, is not an automatic machine, as many users and buyers of YARIS, AURIS, COROLLA cars think.

This gearbox is a mechanical one, or more precisely a mechanical robotic gearbox. Its value lies in the fact that the on-board computer itself selects the optimal mode of gear shifting depending on engine speed, which improves the driving performance of the car, the durability of the components and mechanisms of the engine and gearbox, and fuel economy. The car control system adapts to the driving behavior of a given person, i.e. has a self-learning function.

MMT ensures a smooth ride; the convenience is that the driver does not need to be distracted while changing gears while the car is moving. Cars equipped with this gearbox are more suitable for women, as evidenced by positive reviews from the female half. The transmission is convenient for both novice and older drivers; it is much simpler and easier to operate, does not require additional effort and attention when driving a car and is cheaper to maintain than an automatic transmission.

For drivers who are accustomed to a manual transmission, it will seem dull and slow. Yes indeed, especially when MMT has not yet warmed up, it shifts with a noticeable slowdown, in order to reduce this phenomenon, you should go to the “M” position and change gears manually, while the box does not slow down as much and behaves more quickly.

Another property that is not in favor of MMT is that as the clutch discs wear out, and let’s say, there is a failure in the training program that is hardwired into the gearbox control unit, the car begins to jerk. To do this, you need to periodically, if this problem arises, go to the dealer’s service station and initialize the gearbox, which brings all the data from the training program to the factory settings and the gearbox starts working like on a new car. By the way, this procedure is done completely free of charge on warranty machines. Well, if you have a warranty, then you have to pay. And the more you travel, the more often.

Another very interesting feature of the box is that there is a sport mode “Es”, in which your car will operate more in lower gears, which will entail additional fuel consumption and wear on the components and mechanisms of the engine and gearbox. Therefore, sport mode should only be used in emergency situations, for example when overtaking.

Also, if you need to quickly pick up speed, then you should do this; first release the gas pedal, and then sharply press the pedal to the floor, and you will feel how the car sharply switches to a lower gear, thereby quickly picking up speed. But at the same time, you will notice the same failure in the performance of your car.

In general, we can say that you need to get used to everything. And I'm sure that after driving a car with MMT gearbox, with all the existing disadvantages, it is unlikely that you will want to switch to mechanics.

Diagnostics of the Toyota "robot".

The Toyota robotic gearbox combines the comfort of an automatic transmission and the price of almost a manual transmission, and is quite reliable. Problems with a robot are most often associated with operating and driving characteristics. Most breakdowns of a robotic gearbox are determined using computer diagnostics of manual transmission. Based on the received codes, electrical faults and mechanical problems are identified.

Diagnostics of the Toyota Corolla, Toyota Auris robot includes:

  • visual inspection;
  • checking the functionality of the robot box in various modes;
  • reading fault codes from the gearbox control unit;
  • viewing the operating parameters of all electronic and electrical transmission systems in real time;
  • monitoring the level of transmission fluid and the presence of small metal particles in it, indicating wear of the gearbox parts;
  • checking the operation of gearbox actuators.

Comprehensive diagnostics allows you to accurately determine the nature of the malfunction and determine the most effective type of repair of a robotic transmission on a Toyota.

Replacing the clutch of a Toyota robot

Our experience, gained through numerous repairs, indicates that the weakest point of a robotic gearbox is the clutch. If there is significant wear on the driven disk or basket, release bearing and its guide, replacement will be required, which includes:

  • computer diagnostics;
  • replacing the clutch kit;
  • prevention of the clutch release actuator;
  • initialization of the control unit;
  • necessary computer settings and adaptation;
  • cleaning the throttle valve (if necessary).

Installing a new clutch kit is usually accompanied by changing the transmission oil. New parts quickly change their position after the first grinding in, so after replacing the clutch kit (basket, disc and release bearing), we recommend that no later than after 5-10 thousand kilometers, re-adjust the actuator and carry out initialization and training of the MMT.

Adaptation of robotic gearbox

Replacing the clutch with MultiMode must necessarily be accompanied by an adaptation of the Toyota Corolla, Auris, etc. robot, during which the electronic control unit receives the necessary data about the installed parts, since the thickness of the new disc and the height of the basket have changed. Any repair or even disassembly and reassembly of the transmission for diagnostic purposes, should end with robot adaptation, which allows you to significantly extend the uninterrupted operation of the unit. It is recommended to follow the procedure for setting up and initializing a robotic gearbox for Toyota vehicles every 10 thousand km.

Adaptation of the clutch engagement point is performed using a special scanner and Toyota Techstream software. Regular implementation of the procedure makes driving comfortable and reduces fuel consumption.

Typical malfunctions of MMT and their elimination

If you own one of the Toyota Corolla, Prius, Yaris, Auris or Aygo cars manufactured between 2005 and 2008, then you may have encountered the following problems:

  • jolts and jerks when changing gears;
  • delays in upshifting or downshifting;
  • jerks at start and inability to move smoothly in reverse or forward gear (the car starts moving only at high engine speeds).

The appearance of the listed symptoms due to a malfunction of the robotic box control unit, it will need to be replaced or repaired. There is an express replacement option, when you purchase a refurbished control unit with a warranty, the cost of which is significantly lower than the price of a new unit.

Most common a mechanical failure characteristic of Multimode is wear of the clutch parts which appears as a result of prolonged use or aggressive driving style. In this case, the box goes into emergency mode; to repair it, you should immediately contact our service center.

Heavy vehicle use Toyota Corolla, Auris, Yaris, Aygo or Verso with a robotic transmission leads to wear of the brushes, the appearance of dirt, an open circuit in the electric motor of the actuators, as well as wear of the gears of the drives. The malfunction manifests itself in the form of jerks when starting to move from a standstill; it can be eliminated by carrying out appropriate repair work and replacing worn parts.

The importance of timely repairs and maintenance

When the first symptoms of a malfunction appear, you must immediately contact a service center. Postponing the solution to the problem “until better times” always leads to more serious breakdowns of the MMT, the elimination of which costs the car owner much more. Do not forget about carrying out preventive measures, scheduled maintenance and adaptation of the robotic clutch - the key to reliability and long-term operation.
