Hello everyone,
I’m writing to ask for your help.
My car:
2009 Toyota Yaris, model code NSP90L-CHLGKW, VIN : VNKKH96360A143592
Engine: 1NR-FE, 1.33 VVT-i, 100 hp
Grade: SOL
Transmission: MMT (MultiMode Transmission, automated manual)
Background:
After replacing the clutch, I was unable to complete the calibration/initialization/learning procedure for the MMT. I get error code P0810 and the “N” indicator keeps flashing. I’ve tried several times without success.
I’ve now decided to give up on the MMT and convert the car to a standard manual gearbox. My questions:
1. Is this conversion feasible?
Has anyone here done it, or does anyone know of a build log?
2. Shift lever and retainer
So far I have found the clutch pedal and the clutch master cylinder. However, I can’t find the correct shift lever and retainer assembly. I found this Amayama catalog page:
https://www.amayama.com/en/genuine-catalogs/epc/toyota-europe/yaris/NSP90L/9071/chassis/3312
I’m not sure it is the right assembly for my car. Could someone check it for me and confirm the part numbers? And if they are correct, do you know where I can buy the complete assembly (lever, retainer, cables, etc.)? I’m based in France, so a supplier in Europe would be ideal.
3. Replacing the MMT actuator unit with a cable shift mechanism
I’m not sure how to replace the MMT gear-shift motor/actuator unit with a conventional cable-operated shifter. What is the correct procedure, and which parts do I need to buy for it?
4. ECU and wiring
I assume the ECU needs a different configuration, or some pins need to be bridged or rewired, once the MMT’s TCM is removed. I don’t know how to do this. Does anyone know how to convert the ECU from the MMT setup to a manual gearbox? Do I need a manual-specific ECU, or can the existing one be reconfigured or coded?
Any advice, part numbers or experience would be greatly appreciated.
Thank you very much!
