Mazda Repair Questions? Ask Mechanics for Answers ASAP
Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.
I have enclosed a link to a nation wide source that should be able to find you a used TCM if that's what you are needing. Copy the link below to your browser to open and view the link.http://www.car-part.com/
You are correct, there is no stand alone TCM, the TCM is incorporated into the PCM.
Have you by chance checked the charging system voltage, there have been some known issues with an overcharging alternator interfering with the PCM and causing the transmission to have third gear issues.
Mazda has no service bulletins on any re-flash for this issue, have you ran the pinpoint test for this code by chance?
I would suggest he run the pinpoint test .
