You probably know that Auris and Corolla cars are equipped with a robotic gearbox, which has a number of unpleasant specific properties. Now Toyota has abandoned the use of MMT and has completely switched to automatic and manual transmissions.

But, if you own a Toyota Auris or Corolla that is equipped with MMT, then your chances of becoming familiar with the repair and maintenance of your vehicle’s robotic gearbox are significantly increased.

The “sores” of MMT are quite typical and we will now look at them.

Image #2

1) You started the car, waited a couple of tens of seconds and try to drive, but instead the car drives a few meters, after which it “goes” into neutral and the transmission fault indicator lights up.

In order to continue driving, you need to turn off the engine, wait a little and start it again, only in this way the MMT starts working. What's the matter? And the fact is that MMT is essentially an ordinary mechanical transmission, which has that familiar term “clutch kit”.

In this case, the “release bearing – release bearing guide” pair most likely needs to be replaced.

2) And it also happens: your car stops accelerating normally. No harbinger of trouble was announced, you just can’t move normally.

At the beginning, a slightly noticeable “slip” appears on sharp accelerations, and then the car stops moving normally even from a traffic light. And in this case, the complete clutch kit is to blame.

The whole problem is due to the fact that the MMT has a mechanism for automatically correcting the gap between the driving and driven clutch discs. Due to constant wear, the gap increases and the system adjusts the position of the disks in the “basket”.

However, due to the design features of this system, the clutch can only be replaced as an “assembly”, since it is impossible to return the clearance adjustment mechanism to its original position. It should be noted that to clarify the diagnosis, you will need to remove the gearbox from the car.

Image #3

3) Finally, another popular story associated with a robotic gearbox is jerky movement. You start moving, and the car begins to jerk violently whenever you try to gain speed. Most often, this problem is caused by a failure of the clutch actuator, which leads to either its repair or complete replacement. Luckily for the consumer, there is a clutch actuator repair kit.

Image #4

It is worth noting that it is advisable to carry out MMT repairs (only possible) if there is equipment for computer diagnostics, which allows (without which it is impossible) to carry out high-quality initialization and calibration of the robotic gearbox.

You can find some information on this matter on the Internet (but it’s much easier to contact specialists, fortunately) the cost of repairing an MMT is not as high as it might seem at the beginning.

All of the above problems can cause you a lot of headaches and potential financial costs, so a little about how to optimize the upcoming repair of a robotic gearbox. You need to understand that after driving more than 50 thousand kilometers, your chances of visiting a service center due to the above-mentioned malfunctions sharply increase.

You can delay the inevitable if you eliminate sudden acceleration and braking from your driving habits, and also pay close attention to how you feel when driving a car, because any malfunction is best eliminated from the moment it appears, and not when it is no longer possible to solve the problem without significant financial costs .

So, once again about the range of cars that may require repair of a robotic gearbox: Corolla Verso, Corolla, Yaris, Auris.
A lot has already been said about robotic gearboxes, but we will add that judging by the trends in the automotive market, they decided to abandon the MMT in favor of the classic “automatic”.

Yes, of course, such a decision is not without meaning, since the very controversial unpretentiousness of MMT is easily compensated by the use of a more modern type of transmission.

Even if in an automatic transmission it is necessary to change expensive oil and filters and carefully operate the gearbox, but still, the first interventions in an automatic transmission usually occur after 100 thousand kilometers, which cannot be said about robotic mechanics.

Toyota Corolla with robotic gearbox

13.03.2018

The Toyota Corolla supports the installation of the following types of transmissions: automatic transmission, manual transmission, CVT and robot. The Corolla robot can be found on a foreign car where the volume of the power unit is 1.4, 1.6 liters.

The robotic gearbox absorbs the advantages of automatic and manual transmissions. Fuel consumption on this vehicle is approximately the same as fuel consumption if the car has a mechanic.

Diagnostics of Toyota Corolla with robot

The main advantage of having a robot on the Corolla is smooth movement along the highway. This version of the box includes an ECU control unit with sensors. This makes driving more efficient.

Appearance of the robotic gearbox

Diagnostics of the robot box on a Toyota Corolla is required in the following cases:

extraneous sounds when changing gears;
difficulty changing speeds;
spontaneous activation of speed modes.

In some cases, this is a consequence of the fact that non-original oils are used. The worse the quality of the fluid is poured into the automotive system, the faster the gearbox will lose its operating properties.

The clutch disc can operate for more than 60,000 km. This indicator is influenced by the driving style of the vehicle owner. Timely replacement of transmission oil helps prevent premature breakdowns.

Repair and restoration work

The cost of repairing the robot remains reasonable. Extraneous noise from the gearbox can be eliminated by replacing the release bearings. This procedure can be carried out in a garage.

As a rule, during maintenance of a Toyota Corolla with a manual transmission, initialization is required. This will help identify existing problems. Initializing the box is the process of resetting the previous settings of the transmission ECU.

It should be noted that frequent initialization has a negative effect on the clutch. This will lead to accelerated wear of its component auto parts.

In winter, the owner of a foreign car may encounter a problem such as loss of functionality of the sensor, which is responsible for changing speed modes.

Each individual version of the car requires a certain amount of transmission fluid (approximately 2-2.5 liters). For Toyota Corolla with robot, add oil that must meet SAE 75W viscosity (GL-4 class). Replacing the robotic gearbox on a Corolla 2007 is possible either partially or completely.

Recommendations for operating the machine. When operating a Corolla car with a manual transmission, you should adhere to a number of rules, for example, it is not recommended to press the gas pedal sharply. It is not recommended to skid.

Repair of the Freetronic robotic gearbox control unit

Our technical center can provide you with any spare parts for your Toyota Corolla, Yaris, Auris and Corolla Verso, call!

      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.

        Numbers of control units subject to repair (if the number from your unit is not among the numbers, it does not mean that it cannot be repaired. Call!):

89530-12250 25 Toyota Auris

89530-12290 (Aisin 324811-11900) 29 Toyota Corolla

Services

Due to the increasing number of requests to our technical center for Toyota cars equipped with MULTI-MODE robotic gearboxes (they are used on Toyota Auris, Toyota Corolla, Toyota Yaris), we want to tell you about the problems of this robotic mechanics.

So, what symptoms do our clients present with?
There are three main complaints:

Until the engine is completely warmed up, the car drives normally, and then suddenly, while driving, the neutral switches on and the malfunction indicator lights up, the car does not move forward or backward until you turn off the ignition and start the engine again.

Of course, to make a diagnosis in each specific case, a comprehensive diagnosis of the robotic box (Robot) is necessary. But most often this malfunction occurs due to wear of the friction pair, the release bearing - the release bearing guide.

In some cases, it is enough to change the clutch kit, and sometimes it is necessary to change the front part of the gearbox housing - the robot, because The release bearing guide is integral with the transmission housing.

The warehouse of the automatic transmission center always has in stock the following parts for Toyota robotic gearboxes: Clutch kits, Release bearings, Gearbox housings, Clutch actuator repair kits. At reasonable prices.

2nd Fault: Clutch slipping.

In this case, it is necessary to dismantle the Toyota robot gearbox from the car and inspect the clutch. Most often, the clutch driven disc wears out.

In this case, it is necessary to replace the entire clutch kit, because The clutch basket on these Toyota robots is equipped with a mechanism for automatically eliminating excess clearance between the drive and driven disks.

As soon as the disc wears out and a gap appears, it is immediately eliminated by a mechanism inside the “basket”. When installing a new clutch disc, it is impossible to return the mechanism to its original position.

In this regard, it is necessary to change the clutch on the Toyota Robot assembly.

3rd Malfunction: When starting off, the car moves jerkily.

Most often, this malfunction is caused by a failure of the clutch actuator (the actuator that controls the clutch of a Toyota robotic gearbox). In this case, sometimes an actuator repair kit is sufficient, and sometimes it is necessary to change the actuator assembly itself.

I would like to especially note that all Toyota robotic gearboxes are mechanical devices with a complex electronic control system that require special equipment and certain skills and knowledge.

For example, in order to dismantle the Toyota Gearbox-Robot from a car and not damage the expensive actuators, the robot box needs to be switched to service mode, and in order for the new clutch not to fail several hundred kilometers after replacement, it is necessary to adapt the clutch actuators immediately after any work on the clutch.

All work with the electrical and electronic part of the Toyota Robot gearbox (adaptation of actuators, adaptation of clutch) must be checked using Toyota diagnostic equipment (Intelligent Tester II or Toyota Techstream).

For example, we use Techstream. The Automatic Transmission Center is always ready to help you solve problems with your Toyota Robot. We have everything for this: a huge warehouse of spare parts and modern diagnostic equipment to repair the Toyota robotic gearbox, and most importantly, experienced personnel capable of solving the most complex problems in the shortest possible time.

Error p0810 Toyota Corolla – Autognostics

There are quite widespread rumors that the automatic transmission in Toyota Corolla and Auris cars is a very capricious mechanism, so purchasing a car with such a manual transmission should be avoided if possible. However, the robotic brakes on the Toyota Corolla and Auris are quite strong, especially when compared with analogues from their competitors - Honda, Mitsubishi, Opel, Peugeot.

The frequency of replacing the clutch on the robot box depends on the intensity of driving. On average, this is approximately once every 40-50 thousand km. mileage A clutch kit costs about 12,000 rubles, replacement from 6,000 rubles, subsequent adaptation (“training”) - 2,500 rubles.

Mechanical faults of the MultiMode gearbox

Mechanical wear of clutch parts, in which the clutch loses its functionality. The main sign of clutch failure is slipping , which leads to a loss of torque transmission to the drive wheels at high speeds or during a sudden start from a standstill.

In the event of mechanical malfunctions, the system enters emergency mode and resets the transmission to neutral, while displaying error code P0810 .

To eliminate the problem, you need to replace the clutch kit, which includes the clutch basket and disc, as well as the release bearing.

Electrical faults of the MultiMode gearbox

Malfunctions in the electrical system of a robotic gearbox are expressed in several ways:

Malfunctions in setting or initializing the clutch. Characteristic signs of jerking at start.
Reset to neutral when clutch overheats. A red icon in the form of a gear lights up on the display, indicating a fault in the transmission. After some waiting time, the system starts working again.

Car diagnostics at our service station allows you to find out the exact cause of the malfunction.

Let's look at a couple of the most common electronics errors:.

P0810 clutch position control error . This error occurs both when there is a mechanical failure of the clutch and when there is an electronic failure.
Error P0900 open circuit in the actuator pin drive motor circuit. This error directly indicates an open circuit in the wiring or failure of the clutch actuator motor.

Initializing the clutch of Toyota Corolla and Toyota Auris

Initializing the robotic clutch on Toyota Corolla and Toyota Auris cars in our car service costs 2,500 rubles. initialization every 10-20 thousand kilometers so that the clutch lasts a long time and works properly.

“TURNKEY” REPAIR with selected automatic transmission, removal, installation, oil change

Toyota is famous for its quality cars, but some models have weaknesses.

The pursuit of cheaper production, as well as environmental frameworks, has led to the introduction of robotic systems on Japanese cars. The most unreliable component of the Corolla, Yaris, Auris models produced from 2006 to 2009 is the robotic transmission. It is in this part of the car that frequent breakdowns occur, leading to expensive repairs.

Therefore, premature replacement of a robot with an automatic one becomes a very urgent task for Toyota owners.

Toyota Coroll Auris Yaris Ayqo robots begin to act up in almost 100% of cases. This is mainly manifested in the fact that when driving, the “N” symbol lights up on the dashboard - neutral gear. After this the car refuses to move.

When it shows up in a traffic jam or when stopped at a traffic light, that’s one thing, but when it comes out when overtaking on the highway, that’s a completely different matter.

After such moments, car owners strive to replace the robotic gearbox (RMG) with an automatic transmission, and thereby protect themselves from unexpected expenses.

There are two types of problems that lead to errors and breakdowns of the robot:

mechanical failures;
malfunctions of electrical circuits and modules.

In addition, an oil change is necessary. For example, the Yaris robot requires an oil change after 50-60 thousand kilometers. Resource 110-150 thousand km. robotic boxes very rarely run without problems.

Toyota Corolla, Yaris and Auris clutches are designed for a mileage of 70-90 thousand km. Often you have to deal with overheating or wear of the clutch disc.

Failure of this unit is manifested by disk slipping, which is felt at low and high engine speeds by a loss of torque. As a result of clutch failure, the robot displays an error on the dashboard and shifts the gear to neutral.

The problem is solved by replacing the clutch kit. The kit includes: disc, release bearing and basket.

Problems with the primary and secondary shaft bearings are often possible. They manifest themselves as a hum from the MMT. This problem is solved by replacing the bearings. It is also possible that the synchronizer may fail, which is reflected by a crunching sound when changing gears. In this case, the box undergoes a complete repair.

The exact problem is determined by diagnosis.

Overheating of the clutch causes the transmission to drop into neutral. At the same time, a gear lights up on the panel and a message about a gearbox malfunction appears;
Violation in initialization or settings of manual transmission. When starting, the car jerks. The exact problem is determined by diagnosis.

By replacing a standard manual transmission with an automatic transmission (automatic transmission), you can avoid many problems, including emergency and financial ones. The main reason for replacing MMT is the large number of its shortcomings.

The most common options for replacing MMT are: automatic A240L and U340E. The first option is easier to install compared to the second. The first box is a simple unit that has no serious brains.

Therefore, there is no indication on the panel when the A240L is operating. In addition, the A240L is a simple and unpretentious unit. The second is an original device that is installed on a Toyota Corolla and can replace the Yaris and Auris robot.

The U340E automatic machine is more complex, it has its own brain and an indication of all actions and errors.

Installation of the A240L involves the following steps:

The selector needs to be replaced;
Re-welding and fitting the robot bell to the installation of the machine;
A blende and an additional cooling radiator are mounted;
The existing bracket is not suitable for mounting the box. The bracket is shifted in place;
We install the machine.

Install the U340E as follows:

A new engine control unit is being installed, since it must also control the new automatic transmission;
Change the selector;
We install a new “braid” for connecting the brains;
The indicators on the dashboard also need to be replaced. If this is not done, the operation of the machine will be incorrect and it will go into emergency mode;
The cooling radiator is being replaced;
Automatic is installed.

Replacing a robot box with an automatic transmission involves complex manipulations that must be carried out by specialists.

The Toyota Corolla, Yaris and Auris robot has the following disadvantages:

Unclear selector response;
Servo drives freeze → error message → switch to “N” → car stops;
The cold season causes increased wear on the robot clutch kit;
Damage to actuators.
First

Plus, you need to add the disadvantages of the variator itself:

Non-repairability;
Slipping - the resource is seriously reduced;
It is impossible to overcome obstacles smoothly.

All of the above disadvantages can be solved by replacing the robot with an automatic transmission, and thanks to the automatic transmission, additional advantages appear:

There is no gear shift to neutral when driving.
Automatic transmissions have a high level of maintainability compared to MMT;
Gear shifts smoothly;
The cost of repair work on an automatic transmission is significantly lower than on a manual transmission;
High working resource;

Replacing an MMT robot with an automatic transmission of a Toyota Corolla

Toyota Corolla is a reliable and high-quality car, equipped in some trim levels with a robotic gearbox. The most capricious unit is MMT, so drivers prefer not to mess with it. When does it become necessary to replace a robot with an automatic transmission and how to do it?

The main reason for changing the MMT to an automatic transmission is the failure of the robotic transmission. The first thing that breaks is the clutch. It wears out after 70–90 thousand kilometers and depends on the conditions of use of the car and the intensity of driving.

Clutch wear

There are several ways to extend the life of the clutch:

transferring the MMT to a neutral position during long stops in traffic jams and at traffic lights. This reduces the load on the clutch and the actuator; Neutral MMT
change your driving style, especially if it was initially aggressive. The main load when changing gears falls on the clutch; Aggressive driving style
It is advisable to regularly engage the manual transmission mode. Over time, the control unit records a certain driving style and begins to repeat it automatically. Manual transmission mode

It is advisable to change the lubricant in MMT every 60 thousand kilometers, despite the fact that this action is not provided by the manufacturer. The volume of lubricant filled at the factory is designed for the entire service life - all 100 thousand kilometers.

Mechanical problems

In most cases, car owners have to deal with overheating or wear of the clutch, as a result of which its main functions are lost.

A symptom of clutch failure is slipping, which causes a loss of torque at low starts and at high speeds.
In the event of a mechanical breakdown, the MMT system goes into emergency mode and switches the gear to neutral.

Error code P0810 is displayed on the dashboard. The malfunction is eliminated by reinstalling the clutch kit - release bearing, disc and basket.

Transmission emergency mode

When shifting to third speed from second in MMT, a crunching sound may appear.
The reason for this is wear of the synchronizer as a result of untimely oil changes or failure to adapt the clutch. When the car is moving, an MMT hum may be detected. Eliminated by replacing the bearings of the primary and secondary shafts.

Electrical faults

The reason for replacing the MMT with an automatic transmission may be a malfunction of the electronic system:

Defects in system initialization or configuration. The main symptom is jerking when starting;
Reset to neutral if clutch overheats. A red light comes on on the dashboard, indicating a transmission malfunction.

System diagnostics help identify a specific problem by its code.

Advantages of replacing MMT with automatic transmission

Some versions of the Toyota Corolla are equipped not with a standard automatic transmission, but with gearboxes based on a robotic selector or CVT. This is done in order to reduce production costs and comply with environmental standards. Such “automatic” transmissions have their drawbacks.

Variable speed drive

Robotic gearboxes have the following disadvantages:

Incorrect functioning of the selector;
Freezing of servos;
Clutch wear in the cold season;
Failure of actuators;
Inability of a vehicle to smoothly negotiate an obstacle.

The variator also has its disadvantages:

Almost complete impossibility of repair;
In case of slipping, the resource is quickly lost;
Also cannot smoothly overcome an obstacle;
There is a high level of wear when towing.

In most cases, all such shortcomings are eliminated by replacing the MMT with an automatic transmission. Such a transition from one type of transmission to another has certain advantages:

High level of maintainability, reliability;
Correct functioning, smooth gear shifting;
Increased service life, low cost of repair work;
Gears do not shift to neutral.

The only negative is the termination of the car's warranty service.

Today, there are two main options for replacing a robotic transmission with an automatic one.

The first option is to replace it with an A240L automatic. This process includes the following steps:

Changing the gear selector;Selector
Re-cooking the bell from the robotic transmission to the automatic; Re-cooking the bell
Installation of an additional cooling radiator and a special blende. New cooling radiator

This model of automatic gearbox is hydrodynamic and, unlike its U340E counterpart, is not particularly smart. This box does not imply any indication on the dashboard.

The second option is to replace it with an original automatic transmission from the Toyota manufacturer - U340E. In this case, the installation process is much more complicated and requires the following activities, in addition to those already listed:

Replacing the engine control unit, since it controls the operation of the automatic transmission; Control unit
Changing the gear selector; Gear selector
Adding wiring or completely replacing the braid; Wiring braid
Replacing the instrument panel (if this is not done, the machine will function in emergency mode); Instrument panel
Replacing the cooling radiator.Cooling radiator

The cost of replacing a robotic gearbox with an automatic one varies depending on the specific technician and car dealership. Official dealers carry out similar procedures for an average of 90 thousand rubles.

Tools and materials

MMT replacement is carried out using special CIT kits, which include:

Automatic transmission U340E

automatic transmission;
kickdown cable installed on the automatic;
gear shift cable;
fasteners with which the kickdown cable is connected to the damper;
gearbox linkage and lining;
gearbox rear cushion pin;
hoses and heat exchanger;
a block simulating the operation of MMT;
upper gearbox cushion.

To carry out the transmission replacement procedure itself, additional spare parts and parts are required:

Plastic trim for automatic transmission in the cabin;
Decorative frame;
Bracket for automatic transmission;
Automatic transmission cushion;
Rear and front washers for attaching the flywheel;
Automatic transmission instrument panel;
The engine control unit;
Engine wiring braid;
Flywheel for automatic machine;
Bolts for fastening the flywheel;
Underhood wiring;
Interior wiring for the dashboard;
Cooling radiator;

Bolts for fastening the torque converter;
Two drive shaft oil seals;
Rear crankshaft oil seal;
Automatic transmission oil;
Oil pan gasket;
Oil filter;
Seal for resonator;
Bolt for resonator;
Pressure spring.

The robotic gearbox changes to automatic as follows:

On the purchased automatic transmission, the fastenings are completely digested - the so-called bell; Transmission bell
A gear shift link with a special lining from Toyota Corolla is mounted; Gear shift link
Using special fasteners, the kick-down cable is attached to the throttle valve; Kick-down cable
A simulator is connected to the MMT control unit - a “fake” in order for the car to perceive the new automatic transmission as standard and eliminate emergency mode and the occurrence of errors. MMT control unit

Replacing a robotic gearbox with a manual one is done at the request of the car owner. In principle, this is worth doing if the MMT does not suit the driver when driving: it does not gain momentum, does not pass obstacles well, or the car simply feels uncomfortable. The only disadvantages can be the jambs in the installation of the automatic transmission.

Replacing the MMT with an automatic transmission on a Corolla is a fairly simple procedure, carried out in most cases at the request of the car owner, less often - to eliminate common problems and the general “capriciousness” of the robotic transmission.

Replacing Toyota Auris clutch – cost

Almost half of the Toyota Auris models sold in recent years in the Russian Federation are equipped with a robotic gearbox.

Despite the fact that Toyota Auris is an extremely reliable car, this particular unit turned out to be a weak point, causing unexpected problems for the owner.

Signs of an upcoming Toyota Auris clutch replacement / robot clutch repair?

Sometimes a worn clutch does not show itself until the very end, and at the last moment the “gear” symbol lights up on the dashboard and when the gear is engaged in neutral, the “N” symbol begins to flash.
Shocks and shocks when switching.
Car slipping, that is, gearbox shifting at high engine speeds.
Extreme degree of wear - the car goes into neutral - the “N” icon flashes, the car does not move.

Before replacing the clutch on an Auris, it is highly recommended to conduct computer diagnostics to check for errors.

This is explained by the fact that in addition to wear of the clutch disc itself, the Toyota Auris actuator or clutch drive, the electromechanical device that presses the clutch fork, may fail.

Each malfunction has its own error code, which can be used to immediately make a diagnosis. In half of the cases, it is necessary to change both the clutch and the non-working Toyota Corolla / Auris clutch actuator.

After replacing the Toyota Auris clutch kit, the robot must undergo an adaptation / training / initialization procedure. Without this, the car will move jerkily or not at all.

This procedure can be carried out both without special software equipment and with it.

At the service station this is done only by software, which ensures the highest quality and correct procedure for initializing the Toyota Auris clutch.

Cost of replacing a Toyota Corolla robot clutch at the Orbita service station:

Replacement work, including adaptation (“training”, initialization) – 7,000 rubles.
Clutch kit (manufactured by Aisin (Japan)) – 10,000 rubles (this kit is in the “original” packaging)
Release bearing (original Toyota) – 2,500 rubles.
Additionally (we recommend, but the client decides) it is advisable to change 2 drive seals (they may leak after removing / installing the drive shafts) and fill in new gearbox oil 2 liters, original Toyota (the old one is drained in any case before dismantling the gearbox) - this will add more 3700 rubles
The price does not include diagnostics of errors before work - 950 rubles . Highly recommended!!!

Main works	PRICE	A COMMENT
Replacing the clutch kit (regular manual transmission)	6 000 rub.	Cost of replacing a clutch kit: disc, basket and release bearing
Replacing the clutch kit (robotic gearbox)	7 000 rub.	Includes clutch adaptation procedure

PARTS REQUIRED

Here you need to briefly describe the operating principle of a robotic gearbox.

In principle, this is the same manual gearbox, in which instead of the components responsible for shifting gears (cable, clutch pedal and conditional driver’s foot), there is a clutch drive (Toyota Auris clutch actuator), position sensors and an electronic control unit (a kind of brain that based on incoming data, makes a decision to change gears).

The clutch actuator (actuator), upon command from the control unit, presses the clutch fork, which, accordingly, turns the Toyota Auris clutch on or off.

This scheme is the reason for the early replacement of the Toyota Auris robot clutch. If a person, while operating a pedal, smoothly depresses (turns on and off) the clutch mechanism, then artificial intelligence cannot fully take into account all the nuances.

Namely, over time, the clutch disc becomes thinner as a result of natural wear, and a gap appears between the disc and the actuator end switch.

Because of this, shocks and impacts appear when switching the gearbox, which leads to further accelerated wear of the clutch disc.

According to the mind, it is necessary to periodically (every 20,000 - 30,000 km) initialize the Toyota Auris clutch.

That is, “set” the zero point again - bring the limit switch to the clutch disc, which eliminates the gap, makes operation smoother, and prolongs the life of the clutch.
