Please help, Installed new 4.10 diff. and rebuild transmission with 2400 stall converter. Car shifts great until I try to run it wide open and it hits the rev limiter. I have tried many different changes with the same result.
I am thinking that maybe something is off with the auto configure that I did for the new gear ratio. The 1st and second gear ratios have changed because of the Sonax 2.84 gear installed in the trans. Any help would be much appreciated.
Thanks in advance
