The TCM (Transmission control module) replacement is straight forward procedure. No special training is required.

No programming is required. The shift pattern relearn will automatically take place after a few miles and normal shifting will resume. During the relearn process you may feel harsh shift but it will OK after a few miles of test drive.

Hello, I have verified the VIN to the Mazda catalog. The current TCM part number is XXXXX


The cost from parts.com is $453.92 (NEW).


Let me know if this is helpful, thanks.

Customer:

Thanks for the info! We may also take a look at used parts. Would the model number be the same?

internal88 :

In the salvage yard you may find part number labeled L32E189E1B. This is the old Mazda number. On 11/19/2012, Mazda have issued a new number L32E189E1D. They may have changed the logic in there but I’m not sure about the details.


It won’t hurt the engine or transmission to use the old number. Therefore you can try it.
