Thread: Got a new performance transmission built and installed, same problems occuring.

Anyone else?

Did you end up checking the wiring yet? When I installed my turbo, there was so much **** over the top of the trans that I couldn't see my harness was touching the downpipe. Burnt through it, trans went in limp mode, I repaired the harness and was back in business. Even if you don't get a voltage code or anything, I would still check it out if your having TCC issues.

I would make a list of everything that has been changed or when it started doing it. Rule out everything.
