ROBOT GEARBOX

By the second half of the 90s, Toyota was working with two traditional transmissions - automatic and manual transmissions, and it worked, I must say, successfully. But one day, its marketers noticed that automated (or robotic) manual gearboxes- with all his incomprehensible love for mechanics, residents Western Europe turned out to be no stranger, and at least minimal comfort. Toyota just needed not to deviate from their own traditions - to wait a bit and then borrow technologies already developed by others. But alas, here they decided to manage on their own and learn from their mistakes...

The first experience was impressive in its unreliability Toyota system FreeTronic- mechanical box gears from automatic clutch. TFT can squeeze the clutch, but otherwise ... TFT electronics live their own lives and sprinkle false fault codes. The spool valve, pressure sensor and accumulator quickly end their days. In turn, the finished accumulator makes the electric pump constantly work, which does not tolerate such treatment for very long. The hydraulic drive fluid simply flows out through completely unreliable seals. Of course, this whole set of failed nodes periodically burns the clutch disc (surprisingly, this does not happen as often as it could). In addition to everything, TFT spare parts cost more than impressive money, and for a full-fledged repair, some locksmiths are not enough - you also need a person with a scanner, preferably a branded one. Although the easiest way to solve the problem is by installing a conventional mechanical box.

As a result, the system turned out to be so rotten that even Europeans who were not bypassed by the service network began to shy away from it. And the dynamics of sales made Toyota very quickly forget about FreeTronic technology. But then no one knew that Japanese engineers had prepared a second bomb for lovers of comfortable driving - Multi-Mode Transmission ...

Their task was clear - to make a "like an automatic" gearbox at the price of a mechanical one, and other divisions of the company will try to instill in customers what a breakthrough product they got - an alloy of simplicity and efficiency of mechanics with the comfort of an automatic machine. The experience of TFT has shown that it is better to do without hydraulic drives, the more pure electrics are cheaper and more perfect ... Five sensors, three electric motors - and now the unit is ready, not only independently squeezing the clutch, but also distorting gears.

In just three years in Europe (local car owners do not consider it shameful to share problems and deceived expectations), this box has managed to earn the definition "Dreadful gearbox"- from unfortunate drivers, servicemen and even tow trucks, through which Toyotas with M-MT often move.

In the absence of hydraulics, the number possible faults decreased here. Transmission control units are replaced most regularly, burnt clutch discs and power drives. But the main problem lies not even in the reliability of the parts, but in the fact that Toyota simply could not establish adequate operation of the M-MT and make it durable.

The most innocuous drawback is the impressive slowness of the box when switching. Exhausting jerks and traction dips are inevitable (M-MT is not able to switch, not only without breaking the power flow, but even without releasing gas, therefore it is obliged to choke the motor). When coasting, the box likes to poke inappropriately downshift, when moving uphill, the "robot" gets confused in two adjacent gears and constantly switches up and down. The car rolls back on the slightest hill, which is generally unacceptable for a box that claims to be "as if automatic".

Ideologically, the M-MT was created for economical city driving in traffic jams, but it turned out that there was nothing to do in traffic jams on such a machine. The clutch overheats very quickly, starts to stink, then smokes and finally burns out - it can’t stand the “crawling” cork movement in principle, especially if you need to start off or crawl uphill. When driving with frequent stops the box periodically forgets to shift, so starting from at least second gear only aggravates the fate of the clutch. Another one serious problem- knocking out the transmission and blocking the box in neutral, which occurs not only during stops, but even on the go - this is how a kind of protective M-MT algorithm is implemented. Kindly stop, cool the box a little, restart the engine - and, perhaps, the car will go further. They mostly worry about this: when there is no certainty that it will be possible to complete overtaking or simply turn at an intersection in front of oncoming traffic, it is not very pleasant to drive.

"There are big problems with the MMT gearbox. Last year, when the car was not yet a year old, the car switched to neutral while driving. Fortunately, no one was on the road behind us ... We were told that this is a known manufacturer's problem with The clutch and the new modified parts need to be installed.The clutch and the control unit were replaced.A few weeks later the same problem recurred, and the parts were changed again.A few more weeks passed - and now the problem happened right on the freeway.There were children in the car.The car is back in service "Now they say there is a problem with the ECU software... I hate this car. I'm afraid of it and don't want to drive again. I don't want to risk my life and the lives of my three children."

"The car is good, but MMT is one a big problem. Broke twice already (jammed at N). I took the car to the dealer, they changed the control unit, but to no avail. The car ran 25 t.km and the problems started two months ago"

"We are disappointed. On a run of 5k km, the MMT box jumps between 3-4-5 gears ... Say that they replaced the ECU, but a week later the problems recurred. Now we were told that the ECU was replaced with a modified one, which was definitely checked in in all conditions and works perfectly. On the way home, the gearbox again rushes between 4 and 5 gears. "

"After three months of new car she already got me. Why? I've been driving automatic cars for twenty years now and have been assured that the MMT runs smoothly like an automatic and economically like a manual. She saves money, only she moves with monstrous jerks in automatic or sports modes. The problem is shifting too long - for example, when you are slowly approaching an intersection, the box decides that you want to shift from 2 to 1 and starts shifting. During this time, you are already starting to accelerate - as a result, you get two powerful jerks - when you switch down and immediately when you switch up again. Jerks and the fact that the box wants to completely unexpectedly change gears - I did not expect. All my passengers agree that the car is obviously sick. Checked twice at Toyota dealers - they say that it works fine. Talking with technicians, I heard different stories..."

"I have a Verso with MMT and a lot of problems with it. I've ridden six so far different Toyotas and I can confidently say that there has never been such a duet of slowness and unreliability. The transmission has broken more than 5 times to date. A new ECU has been installed, but the problems continue, from time to time the car shifts gears to neutral and does not go ... "

Against this background, private advice from Toyota officials on driving with M-MT sounds simply mocking:

- If shifting becomes inefficient, then move on even gas for a while, allowing the transmission to rest.
- Help shifting gears - if you release the gas just before the moment of shifting, then it will happen more smoothly.
- Do not press the gas pedal too hard to prevent the protection from tripping and resetting to neutral.
- In order to prevent cyclic switching during long uphill driving (for example, 3-2-3-2-...), switch to manual mode and force a lower gear.
- To reduce shift jolts, accelerate smoothly without depressing the accelerator pedal more than half way.
- It is impossible to move at a very low speed, especially on a hill, otherwise the clutch will overheat with constant slipping. In this case, stop and cool it down.
- Try to drive in modes where the clutch is fully engaged.
- Try to avoid driving in dense city traffic jams.
- M-MT system - a new word in Toyota technologies and needs some adaptation. Try to rebuild your driving skills and driving style.

All this, of course, is nonsense - for this, automatic and automated boxes are bought so that when driving, you don’t have to think about them at all. It is for slow driving around the city, for easy starting uphill... And the car owner does not have to adjust to the next "brilliant" invention of Japanese engineers every time. You cannot make a workable unit yourself - so do not shift these problems to buyers.

Or maybe build a normal robotic box for mass machines basically not possible? No, it’s very possible - take at least transmissions concern VAG... But, unfortunately, there is a huge distance between their advanced DSG with two multi-plate "wet" clutches and the poor ersatz automatic offered by Toyota.

It is worth noting that primitive "robots" in Europe were introduced more as an alternative to mechanics than as a replacement for automatic machines. Therefore, thinking about the future, automakers offer a choice of all three options - a "cheap" basic mechanics, a slightly more expensive "robot" and an expensive classic machine. However, Toyota went the other way, completing all junior models. European market only mechanics and M-MT - Yaris, Corolla Verso, and now a new generation of Euro-Corolla. Probably, lovers of ordinary mechanical boxes still ride on these machines, but in our metropolis, where for daily driving the machine is already simply necessary, you have to forget about the existence of such models - it seems that Corolla history ended. Those who wish to continue to sponsor experiments on themselves can stay with Toyota, but what about the rest? Fortunately, there are enough others in the world normal cars with normal transmissions.

On brand cars Toyota Corolla, Toyota Auris, Toyota Yaris, Toyota Aygo, Toyota Corolla Verso 2005-2009 with a Fretronic robotic gearbox, a malfunction of the MMT control unit is quite common.

The cost of repairing the electronic unit of the Freetronic robotic gearbox removed from the car is 7,000 rubles (removing and installing the unit from a Toyota Auris, Corolla, Corolla Verso car - 1,000 rubles, for a Toyota Yaris car - 3,000 rubles).

ATTENTION NEW SERVICE - replacement of the clutch with subsequent adaptation of the gearbox - 8,500 rubles (the cost of only work, without spare parts, the car is accepted by appointment for 1-2 working days! Ordering spare parts at the Freetronic gearbox is also possible!).

Replacing the clutch actuator with subsequent adaptation - 2,500 rubles (by appointment!).

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

The Freetronic robotic manual transmission (sometimes referred to as Multimode or simply MMT) was developed from the traditional mechanical transmission by adding drives switched by electric motors. By adding electronic system management became possible auto mode gear shifting and manual.

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

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

The only plus compared to the usual automatic transmission- possibility manual switching gears with the help of paddle shifters and slightly lower (~ 0.5 liters) fuel consumption. AT this moment Toyota does not install this transmission, but it continues to work in a slightly modified form on Peugeot / Citroen cars.

The defect on Toyota cars (Toyota) with an MMT robotic transmission manifests itself in the loss of assistance when starting off, when gas is added, the car twitches (manifested when starting to move and when starting forward and backward). With computer diagnostics, this error can be detected (sometimes there are no diagnostic errors at all!):

P0810- common error clutch positions

P0900- error in the clutch actuator circuit

The disease is present on cars, the MMT transmission control unit numbers end in "0" or "1" (cars before 2008, by the end of 2008 Toyota began to install new units with the number "2" at the end, where the problem was fixed once and for all ). In 2009 year Toyota decided to abandon this transmission in favor of the usual "automatic".

Diagnostic "robot" Toyota.

The Toyota robotic gearbox combines the comfort of an automatic transmission and the price of almost a manual transmission, moreover, it is quite reliable. Problems with the robot are most often associated with the peculiarities of operation and driving. Most breakdowns of the robotic gearbox are determined using computer diagnostics RKPP. According to the codes received, malfunctions of the electrical part, as well as problems in the mechanics, are detected.

Diagnostics of the robot Toyota Corolla, Toyota Auris includes:

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

Comprehensive diagnostics allows you to accurately determine the nature of the malfunction and determine the most efficient view Toyota robotic transmission repair.

Toyota Robot Clutch Replacement

Our experience, gained as a result of numerous repairs, indicates that the most weak point the robotic gearbox is the clutch. With significant wear of the driven disk or basket, release bearing and its guide will require replacement, which includes:

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

The installation of a new clutch kit is usually accompanied by an oil change in the transmission. New parts after the first lapping quickly change their position, therefore, after replacing the clutch kit (basket, disc and release bearing), we recommend re-adjusting the actuator and initializing and training MMT no later than after 5-10 thousand kilometers.

Adaptation of a robotic gearbox

Replacing the clutch with MultiMode must necessarily be accompanied by the adaptation of the robot Toyota Corolla, Auris, etc., during which the electronic unit control receives the necessary data about the installed parts, since the thickness of the new disk and the height of the basket have changed. Any repair or even disassembly-assembly of the transmission for the purpose of diagnostics, must end with the adaptation of the robot, which significantly extends the uninterrupted operation unit. The procedure for setting up and initializing a robotic gearbox for Toyota vehicles is recommended to be performed every 10 thousand kilometers.

The adaptation of the clutch setting point is carried out using a special scanner and software Toyota Techstream. Carrying out the procedure regularly makes driving comfortable and reduces fuel consumption.

Typical MMT malfunctions and their elimination

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

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

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

The most common mechanical failure characteristic of Multimode is the wear of clutch parts, which appears as a result long-term operation or aggressive driving style. The box then goes into emergency mode, for its repair, you should immediately contact our service center.

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

The importance of timely repair and maintenance

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

Owners of used Toyota Corolla often encounter the problem of the correct and uninterrupted operation of a robotic gearbox. The Japanese have long admitted their mistakes in creating MMT for their cars. The occurrence of any breakdowns with the robot entails unscheduled repairs and initialization of all parameters. In order for the initialization of the Toyota Corolla robot to be successful, you need to perform a series of “procedures” that will help you set up the entire transmission system with high quality.

The robot is one of the leader's many "projects" Japanese car industry which simplifies the whole process of driving a car. The system is designed so that the driver does not think about the "mechanical" gear shift. Thus, the robot controls the transmission much better than the well-known machine.

Robotic gearbox Toyota Corolla

MMT included an ECU control unit and sensors that give signals when the car is moving. The transmission system itself has remained virtually unchanged, it contains a clutch and a manual gearbox, which in turn is driven by a robotic drive - an actuator. The control mechanism completely links the entire system, thereby making it automatic or semi-automatic, and also allows for manual operation.

A characteristic advantage in the MMT Toyota Corolla is driving comfort, of course, automatic transmission more smooth and familiar to everyone, but the robot has a number of abilities that are beyond the power of the "machine". For example, in MMT, fuel consumption remains at the level of "mechanics", and reliability in operation and the cost of maintenance are much cheaper than "automatic". But whatever it was, any box has its pros and cons.

Problems with the robot Toyota Corolla

The Japanese debuted their first car with a multi-modal transmission at the end of 2006. Sales of cars with a robot did not last long on the market, as Toyota admitted its shortcomings and mistakes in creating such an interesting and attractive gearbox. Therefore, the Japanese were forced to withdraw from production given type Checkpoint and introduce insurance for purchased cars for a short time. The owners of the Toyota Corolla robot faced such a number of problems:

• Malfunctions in the control unit system, which led to common problems and unscheduled initialization procedures, sometimes every 10 thousand kilometers
• If not functioning properly, the box contributed to overheating of the clutch disc and premature wear. There were cases that the clutch required replacement already at 50-60 thousand kilometers.
• Interruptions in switching from one gear to another. Most often this happened in long traffic jams. MMT “thinks” for a long time, such a reaction leads to a slow movement of the car or contributes to jerks.
• Problems associated with the computer, due to which the above listed failures and malfunctions in the system appeared. I had to do a complete update of this control unit.

To date, "insurance" from Toyota for robotic gearboxes still exists. Specialized car services are ready to carry out complete replacement all elements of the MMT system. You can use warranty card, but no one knows how long the “free” service will last.

What is the initialization of the robot gearbox on a Toyota Corolla car?

Initialization, in other words, resetting or setting parameters in the ECU. Most often, initialization on Toyota Corolla 2008 is carried out when replacing any elements of a robotic transmission:

• Replacement complete set MMT or partial renewal of clutch or gearbox elements (transmission is being initialized).
• Replacement of the electric unit and electric drive, as well as sensors (the ECU unit is being initialized).

Adjustments or calibrations are performed on unknown errors or failures.

When should you not initialize a Toyota Corolla robot?

More on the topic:

Corolla initialization should not be carried out, without any reason or complaints. The ECU does not like frequent updates, so an incorrect failure or calibration can lead to negative consequences. After initialization, there may be short-term positive effects but it's not for long. Unwanted parameter setting leads to increased wear all elements of MMT.

There are a number of erroneous opinions that seem to have a positive effect on the operation of the MMT during initialization:

• It is not necessary to carry out a reset if the position of the clutch supply drive rail is not correct.
• With delays in gear shifting, as well as jerks at low speeds.
• After the ECU settings, without intervention in the system, the car will not move better.

All procedures related to the initialization of the box or block must be carried out with the recommendation of professionals or the obvious occurrence of reasons for this.

The procedure for collecting or setting up the transmission system should be carried out by specialists, but if you decide to do it yourself, then follow the instructions step by step:

1. We put our Corolla on the parking brake.
2. We make a jumper in the DLC3 block of contacts CG and TC (we close the contacts with a paper clip at number 4 and 13).
3. We turn on the ignition and press the brake at least seven times (two short beeps will sound), this will mean that the car has started diagnostics.
4. Press the brake pedal and perform the following gear changes:

When setting electric block control: N - E - V then "minus" - M - "minus" - M - E - N

When initializing the clutch: N - E - M - "plus" - M - "minus" - M - "plus" - M - "minus" - E - N

With MMT settings: N - E - M - "minus" - M - "minus" - M - "plus" - M - "plus" - E - N

1. We release the brake and press it again, we expect a series of signals (the element we have selected is being configured).
2. With the correct process for initializing the Toyota Corolla robot and successfully completing it, you will hear:

Two sound signal- ECU setup completed successfully.

Three beeps - Clutch initialization completed without errors.

Four beeps - the transmission is configured without errors.

1. Turn off the ignition and disconnect the contacts TC and CG.
2. If continuous beeps occur during setup or after it is completed, it will indicate that it was not performed correctly or with errors. To correct this problem and reboot the system, remove the key from the ignition and wait ten to fifteen seconds. Then start initializing Toyota Corolla again.

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

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

MMT provides a smooth ride, convenience in that the driver does not need to be distracted at the moment of shifting gears while the car is moving. Cars equipped with this gearbox are more suitable for women, as evidenced by positive reviews female half. The box is convenient for both beginners and older drivers, it is much simple and easy to drive, 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 mechanical, it will seem dull and slow. Yes indeed, especially when MMT not yet warmed up, it shifts with noticeable braking, in order to reduce this phenomenon, you should move to the “M” position and shift gears manually, while the box slows down less and behaves faster.

Another property not in favor of the MMT is that as the clutch discs wear out, and let's say, a failure in the training program, which is hardwired into the gearbox control unit, the car starts to twitch. To do this, periodically, if this problem occurs, call in at the dealer's service station and initialize the gearbox, which brings all the data of the training program to the factory settings and the gearbox starts to work like on a new car. Incidentally, this procedure warranty machines done completely free of charge. Well, if you have a warranty, then you have to pay. And the more you drive, the more often.

Still very interesting feature box, there is a sport mode "Es", in which your car will work to a greater extent in lower gears, which will entail additional fuel consumption and wear of components and mechanisms of the engine and gearbox. Therefore, the sport mode should only be used in emergency situations, such as when overtaking.

Also, if you need to pick up speed sharply, 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 will abruptly switch to a lower gear, thereby picking up speed sharply. But at the same time, you will notice all the same failure in driving 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, you are unlikely to want to transfer to mechanics.
