Modern boxes, along with undeniable advantages, also have some disadvantages, which are primarily associated with their more complex design. Replacing the clutch of a Toyota Corolla robot produced in 2007 and 2008 is one of those operations that car enthusiasts are constantly faced with. This is explained by the fact that the developers of the robotic transmission for the 2007 and 2008 models did not take into account some points. It is because of them that gearboxes of this type cannot boast of operational reliability. Usually their resource is only enough for 70 - 100 thousand km in our conditions, which, to put it mildly, are far from ideal.
Repairs at a robot service station are expensive, so it makes sense to purchase the clutch yourself and replace it yourself.
Replacement instructions
Saving on repairing a robotic gearbox for a 2007 and 2008 Toyota Corolla is, of course, a tempting prospect. But first of all, you need to carefully read the instructions we provide and strictly adhere to the sequence of operations performed.
Required tools and materials
- a set of keys;
- screwdriver;
- Toyota Corolla 2007 or 2008 clutch kit;
- container for draining oil.
Stages
After you purchase a replacement kit and prepare the tool, you can proceed directly to the replacement work.
- First of all, disconnect the air sensor.
- After loosening the clamps, remove the air ducts.
- Remove the air filter element.
Disconnect the sensor, air ducts and filter
- We unscrew, but do not remove the bolt securing the gearbox cushion.
- We disconnect the connectors from the box.
- Unscrew the fastening bolts.
Disconnect the connectors and unscrew all the fastening bolts - The next step is to disassemble the ball joint.
- We drain the transmission lubricant mixture from the robot box.
- Unscrew the hub nuts.

- Unscrew the front gearbox mount.
- We take the drive shafts out of the box.
- We lift the gearbox so that the bolt located at the top of the box can be easily removed. If you haven’t figured it out yet, this is exactly the bolt that was unscrewed at the beginning, but not removed. Pay attention to the oil seal; if it wears out, it needs to be replaced.
- We unscrew the remaining bolts that secure the gearbox robot.
- Pull it away from the engine a little.
Removed box - Remove the clutch from the flywheel.
- Checking the flywheel. Wear should not be more than half a millimeter. There should be no irregularities or roughness to the touch. Otherwise it changes.
Transmission flywheel We install a new clutch kit for Toyota Corolla 2007 or 2008.New clutch kit
- Center the clutch disc.
- We change the bearing.
- At this point, the process of replacing the clutch robot on a Toyota Corolla can be considered complete.
- We put the dismantled components in place in the reverse disassembly sequence.
Which clutch is better to choose?
New Toyota Corolla clutch basket
Many car owners who use Chinese clutch kits for robotic gearboxes for cars produced in 2007 and 2008 speak positively about them. They performed well in our operating conditions, but their cost is much lower. Installing a Chinese-made robot clutch kit will cost much less.
Initialization
When all the components are in place after replacement, you need to initialize the clutch to change gears correctly. If you have not done this before and have no idea what we are talking about, then it is better to contact a professional. After initialization, your Toyota Corolla car can be considered ready to drive.
This procedure is performed every 20,000 km; this is necessary to extend the life of the clutch and make it more stable.
If you don’t have a friend who can carry out initialization on the spot, then you will have to get to the service station on your own. This is possible, but you need to follow some rules.
- Turn off the ignition, depress the brake pedal, and set the gearbox to neutral.
- Turn on the ignition, leave the handbrake in position N. Wait about 45 seconds, turn off the car.
- Turn it on again and wait another 20 seconds. Turn it off.
- This time, together with the ignition, we start the Toyota Corolla engine, without releasing the brake pedal. The N indicator should flash on the dashboard; wait until it stops flashing - this means that the system is configured.
- If the indicator continues to flash, it means that the actuator rod is not tensioned. To tighten it, you need to move it or place washers under it, a couple of millimeters is enough.
As you have seen, there is nothing difficult in replacing the clutch; if something is not clear, then watch the video or in the comments.
Consequences of improper care of the mechanism
It is also necessary to remember how long the car runs on the original clutch. If you do not take into account the period of maximum possible operation of the mechanism without maintenance, then the car begins to slip and skid literally out of the blue. Also, the reverse gear may not turn off or, on the contrary, it will turn off for no reason.
Therefore, after removing all components of the clutch system, it is necessary to carefully check everything and, if there is severe wear, replace certain parts. This applies to both automatic and manual transmissions. A well-made replacement eliminates the presence of play and squeaks in the gearbox. Therefore, the assembly process must be performed carefully and carefully.
Now you need to decide on the question, which clutch is better to install? It is worth knowing that the clutch for a 1.6 liter engine and a 1.5 liter engine will be the same.
So, it is best to install original parts of the coupling mechanism. However, if they are too expensive or are out of stock, then you need to “stock up” with high-quality analogues.

Press it again, you should hear 3 series of 2 beeps; In 2 seconds, press the pedal 3 times, if you did everything correctly, then you should hear 3 signals; The ignition is turned off and the jumper is pulled out.
Replacing the clutch on a Toyota Yaris – Red Line Service
If you do not hear the signals, or the interval between them is more than 0.5 seconds, then wait 15 seconds and start working from the beginning. Toyota's robotic boxes turned out to be not of very high quality. Therefore, their use was abandoned quite quickly. But some cars were equipped with such a transmission. Therefore, replacing a Toyota Corolla robotic clutch is a pressing problem for a certain part of car enthusiasts. Mechanical failure is mechanical wear of clutch parts.
Basically, this is wear and overheating of the clutch, during which the clutch loses its functionality. The main sign of clutch failure is slipping. In the event of mechanical failures, the system enters emergency mode and resets the transmission to neutral.
Displays error code P Crunching in MMT when switching from second to third gear.
This is due to wear of the third gear synchronizer. Noise from the MMT when the car is moving. Eliminated by replacing the rear bearings of the primary and secondary shafts. Malfunctions in the electrical system of this gearbox are expressed in several ways. The first is a malfunction in setting or initializing the clutch.
Characteristic signs are jerking at startup. After we have removed the drive shafts, we need to lift the box so that the upper gearbox mounting bolt can be easily pulled out. We take it out - for those who didn’t understand, this is the bolt that we unscrewed but didn’t pull out at the very beginning.
It is important to pay attention to the oil seal; if there is oil around it, when installing the structure we will have to replace it in order to eliminate the oil leak. Having pulled out the bolt, unscrew all the bolts securing the box and slightly pull it away from the power unit. The box removal process is complete. Only one oil goes into the robot: Although you can fill in analogues, at very low temperatures at the beginning of the trip you can hear unpleasant sounds from the box when switching.
Self-replacement of the clutch on a Toyota Corolla robot
Judging by the Toyota forums, there are no such sounds with this oil. After assembly, you need to configure the robot. The robotic box has five functions you need. Below are descriptions of all five, and then it is described what needs to be done from this. The first four algorithms are popularly called the “paperclip method” or “slipper method” tuning. We are looking for the diagnostic connector, it is under the cover to the left and below the steering wheel.
The ignition is turned off, the gearshift lever is in neutral. Press the brake seven times within three seconds so that the lights in your feet blink.
Press and hold the brake pedal. Move the gear selection knob.
Why does a Toyota Corolla robot clutch need to be replaced?
The driving sequences are different for different functions, only one of the following four functions can be performed at a time: Moving the clutch actuator to the clamping position: Initializing the ECU: Initializing and setting the clutch: Release and press the brake pedal again. The buzzer will emit as many signals as the function you performed for 6. Press the brake pedal three times in two seconds. The brain will give out several signals. Turn off the ignition and wait 10 seconds.
Disconnect the paperclip from the connector. There is also a fifth adjustment algorithm, without using a paper clip.
But it only does setup, without initialization. We wait at least 40 seconds. Take a container prepared in advance and drain the transmission fluid from the PDA.
Using a suitable wrench, unscrew the hub nuts. Disconnect the ball joint mounts to remove the drive shafts. Remove the front transmission mount and pull out the drive shafts.
Now carefully lift the gearbox - in this position, access to the upper fixing bolt will open; you unscrewed it at the very beginning of work.
Every fan of Japanese cars has probably heard that replacing the clutch on a Toyota Corolla robot is a complex process. Many car enthusiasts want to save money on transmission repairs, and this is, of course, a tempting prospect. But the most competent decision is to entrust the repair to professionals.
If you are looking for information that will help you understand and understand this issue, then you have come to the right place. On this site you will find comprehensive information on servicing the box, and also receive highly qualified assistance from professionals. The most vulnerable point in the MMT robotic gearbox is clutch failure. Its average service life in a Toyota Corolla is from 70 to 90 thousand kilometers.
The operating conditions of the Toyota Corolla, the intensity of use and the driving style of the car have a great influence on his life. When operating in city mode, the life of the clutch decreases due to the constant tension in which it is located. If the car is used more often on the track, the clutch may last much longer.
Mechanical replacement
The process of replacing a manual transmission clutch on a Toyota Corolla with a 1.6 engine capacity will differ significantly from replacing a similar mechanism on a robot. However, even on the mechanics, everything can be replaced with your own hands, without contacting a service center. It is important to note that the main reason for replacement is that the clutch is slipping. That is, when the speed increases, the car will not accelerate properly.
The process of replacing the clutch mechanism on a manual 2008 Toyota Corolla begins with removing the gearbox. It is removed in exactly the same way as when replacing the clutch on a robot. It is important to note that you need to remove it carefully, trying not to damage other components and mechanisms of the car. Having removed the gearbox, you can directly begin disassembling the vehicle’s clutch system.
You need to remove the flywheel and inspect it carefully. If this is not done, then there is a high probability that worn parts of the flywheel will cause a more serious breakdown. For example, if the clutch does not release, freezes, and reverse is constantly disabled, then the problem is a worn flywheel. In addition to the flywheel, it is necessary to check the pressure and release plates. Well, when replacing, it’s worth considering that you should change not only the discs and flywheel, but also the fork and basket. After installation, you need to cock the basket. The cocked basket will work long enough and reliably.
It is worth remembering that a well-installed coupling mechanism on the Toyota Corolla 120 body and other models guarantees long and reliable operation of the car.
Mechanical breakdowns of manual transmission
Mechanical failure is the physical wear and tear of manual transmission mechanisms. This is mainly due to overheating, which subsequently causes the clutch to lose the ability to perform its direct function. In addition, when overheating occurs, the actuator wears out. In case of mechanical failure of the manual transmission, the Toyota Corolla system switches to emergency mode, and the N icon lights up on the car control panel.
During diagnostics, the malfunction is identified as error - P0810. The error is the most common; to eliminate it, you will have to perform one or more actions, depending on the diagnostic results:
To replace a complete clutch at a car service center, you will have to pay about 70,000 rubles, which, in general, is not very cheap. Since this is an error, the most common professional diagnostics can accurately determine the malfunction.
Our specialists will help you detect a specific breakdown, the repair of which will cost much less - the price of fixing a precisely localized problem ranges from 16,000 to 21,000 rubles, and in some cases only wiring and adjustment will be required.
The characteristic crunching sound in the MMT gearbox when changing gears is associated with a breakdown of the third gear synchronizer. Such a breakdown can be caused by untimely oil changes and lack of adaptation of the clutch itself. In the future, this can lead to breakdown of the gears, as well as the gear selection mechanism itself.
Noise from the MMT gearbox occurs when the oil is not changed on time; in addition, noise can occur due to damage to the primary or secondary shaft. This breakdown can be repaired by replacing the damaged shaft.
Where do problems with the clutch of a robotic gearbox begin?
Like any mechanism, the clutch of a robotic gearbox on a Toyota Corolla has its own natural reserve of wear, sooner or later it runs out. When this happens, the car becomes very unpredictable:
- at high speeds the clutch begins to slip;
- the car begins to accelerate more difficultly, or even cannot gain sufficient speed at all. At the same time, a very characteristic smell of burnt metal appears;
- sometimes this is expressed in the other extreme - the car may start too sharply from a neutral position.
If you go to a service station, they will most likely tell you that the car needs a complete clutch replacement, although this may be far from reality. Most often, only the clutch disc fails, but the basket and bearing can be in quite good condition and will serve you for hundreds of thousands of kilometers.
This is another reason why you shouldn’t fly to the service station headlong.
Weaknesses in the gearbox electrics
A Toyota Corolla with a robotic gearbox has several major electrical faults. The first malfunction may be in the initialization of the clutch and its adjustment. Signs of this breakdown appear in shocks when starting to move. The second reason is that the system resets to emergency mode when it overheats. With such a malfunction, a gear sign lights up on the control panel, which indicates problems in the transmission. If you wait a little, the system will restore its operation again.
When carrying out professional diagnostics, such problems are identified by an error code. The first P0810 is a control error. Basically, this error occurs due to a mechanical defect in the box, and can also appear due to electrical damage. The second error P0900 clearly indicates an open circuit or destruction of the actuator motor. In this case, you will have to replace the motor. The price of the motor is around 7,500 rubles.
The clutch life of robotic gearboxes depends on driving style. On average, the mechanism lasts 70-90 thousand km, after which it requires updating and adjustment.
Work order
The cost of replacing a “robot” clutch is noticeably higher than that of a conventional manual one. This is explained not only by the higher cost of a set of spare parts (disc, basket and release bearing), but also by the need to perform additional operations:
- removal and installation of the drive (actuator);
- initialization of the MMT control unit.
In addition, an experienced specialist will evaluate the condition of the oil seals, flywheel, and release fork and replace them in the event of a malfunction. Units manufactured before 2009 may require an upgraded control unit.

I’ll write about a situation involving a robot that I encountered not long ago, or rather, repairing a clutch actuator on a 2008 Toyota Corolla. I wanted to change the transmission to an automatic transmission, but 75 thousand is a bit expensive, for that money they do it on a turnkey basis. There are ready-made installation kits from 55 thousand, but I read reviews, it happens that they forget to put something in the kit, and then you won’t be able to question it. And how long this box will last is unknown.
There was an attempt at repairs at stations in our city, but we do not have highly specialized robot specialists. We are ready to change everything until the car runs, but this is not an option.
By reading forums and technical literature, I found out that according to my symptoms, namely, a departure to neutral, followed by waiting 10-15 minutes for the car to “cool down,” it was possible to drive further, to the first turn, then departure again. Initialization did not work or did not help.
The clutch release actuator is to blame. The fact is that the Japanese comrades decided that it would be technically correct, and most likely more economical, to place the shafts inside the mechanism, on steel bushings coated with fluoroplastic (but this is not certain
