Hey I just got my car on the road 2 days ago and seems like when I really get into it my car dosent seem to shift it just hits the rev limiter but driving just normally it shifts just fine, it seems like 3rd takes longer then it should to change, Ive got a TCI 2800 Stall and it has a PCMforless tune, any idea why its not shifting right?

 

Sounds exactly like mine. It worked fine when i first got the setup going but after driving around on a modded motor with a stock 110k tranny, it decided that it didnt like 3rd gear so much. I have to let off to get it to shift into third so im pretty sure the tranny is toast.
