2011 Mazda 3 I was wondering if you help with this problem. I purchased TCM on ebay and suspecting it is faulty. The part number: LF8M 18 9E1G is exact as my old one. After about 20min of driving starts to malfunction on and off (with AT light on and off, traction, and gear selector) and it goes back to normal for a while. Could this be faulty TCM?

It sounds like it could be an issue with the TCM, however, we cannot diagnose your part based on this message. If you wish to send it to us, we can test it and see if it actually needs repair. If the unit tests good then you will only pay a $39.99 bench test fee along with any applicable shipping charges.
