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

Here is a video, the quality is crappy because its from my phone, but listen for the change in exhaust tone at 11 seconds. It feels like the car gets kicked in the rearend and it actually moves, really fast. In the video it reminds of VVT or VTEC the way it changes tone then goes. Just watch and listen, it shifts into second at 8 seconds, then decides to actually rap the gear out and go at 11 seconds. I am at part throttle feathering in first to not blow the tires off, then i'm at WOT at the end of first and the rest of the way.

thats weird how its bogs then kicks in

Bump for more input. Brian (Reptile) messed with the tuning a bit and managed to change some things for the better, thanks Brian, but the problem is still a bit there. 1-2 at WOT will sometimes not do it now, but 2-3 is a whole nother story. 2-3 at WOT shifts at around 6k then sits at about 3750 in 3rd for like 6 seconds, ridiculously long, then gets a match lit under its balls and runs like a bat outta hell. I just cant wrap my head around why it's every single gear....

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.
