My car won't shift under WOT into 3rd just stays in second and hits the rev limiter untill I lift. It just started doing this with no warning, it had never done anything like this before nor has it ever even hit the limiter between shifts. It's like at 5500 rpm it goes to neutral and hits the limiter untill I lift. Any ideas?

 

Do you know anyone that has HP tunners that can check the codes.

 

3-4 clutch pack is toast ,get ready to do the tranny,been there,doing that.
