Hi Gents,

I am having problems with the Toyota MMT system. I have decided to change it to a manual transmission. Conversion is done but the car just idles and wont rev.

I used Techstream and can see various MMT related codes. They are logged as permanent and therefore cannot be cleared (sin techstream)

Please advise as it appears that many of you have had much experiences with the MMT.

All of the best for 2019

Hi Vasko,

Can you fix the problem? I have the same trouble and the N dissapeared. I don t now how, but before replace the clutch kit, I've got the same problem and did many things (disconnect Battery, remove fuses, turn off, turn on, etc), and in some of these stages, the N reappeared. But now, still unavailable.

Ok friends ....had the same problem with a 2004 Corolla mmt

Car came in for clutch replacement.....after changing the clutch kit (friction plate ,pressure plate and bearing) the "N" was still there ,car starts and revs but there was a problem when changing gears....so it was obvious that it was a matter of actuators relearning (clutch and gears actuators).I choose to do it by obd pins brake pedal and gear selector........I hear the clutch moving ,I hear the gear selectors moving.....and that was it...."N" dissapeared!!!No faults car starts no revs no "N"....beautiful!!
I did the relearning maybe 1000 times, with new baterry....with new baterry and charger ,new clutch actuator.....new gear actuators.....relearning with techstream(another 1000 times)....nothing.....talked with 2 different Toyota specialists and got the same answer....even with the genuine clutch kit from Toyota they have exactly the same problem....so they keep changing clutch kits until it works....sometimes they are lucky and works fine from the first attempt!!!

What I did......I used the new friction plate with the old pressure plate....put everything back together.....did relearning procedure with techstream and BOOM.....N was back.....car starts revs and changing gears perfectly!!!

So I guess if you have the same situation after clutch kit replacement .....without faults maybe this is the solution to your problem....it worked for me!!!

FIXED!!

SOLUTION: after hours of google, thinking and trying diffrent things i know the solution.

I replaced the clutch and started to program it without diagnostictool. Flllowing the blue print PDF. All went well til the part where the wait of 40sec when the mmt system was suposed to lern...

The screen showing the N, E and R became blank.

We noticed that the actuator moved very very little sometimes when we turned the ignition on/off. Thats when we came to the idea that it was to far from its right position for the actuator to adjust it by it self. So I screwed loose the actuator, grabed a crowbar and pushed "the arm" that goes in to the clutch and moved that arm and the loose actuator. I held it in that position and ny friend attached the actuator.

Now we turned the ignition on AND THE N APPEARD!! I now followed the steps in the blueprint and IT WORKED

But I still gonna Contact toyota tomorrow and let them go in to the system by computer and check the calibration. I really dont dare to risk that the clutch breaks again. It moves very little when it switches so the calibration need to be very perfect.

hi guys, Toyota corolla 2004 with MMT gearbox. trying to help a local garage who have changed clutch on this car. basically car was starting but no drive/revs or gear display in dash after clutch change. i tried to reprogram with launch x431 [ gear learn etc] went through process okay but still the same

also tried manual way [ blue print] again went through all ok [ beeps and all] still the same

. and now the stupid car wont turn/crank over..battery is fine , no faultcodes in system what so ever. its as if you're trying to start in wrong gear.. any help/ideas would be a god send. thanks guy

Dear all I fond the solution for mmt gear, toyota Corolla
Just adjust the clutch actuator until to end by12mm those 3 bold, make sure very little pre ply around 1mm
After that do directly initilitiation by diagnostic I used x431
That mean no3
Every thing perfect
