    8L90 Transmission Slip

    I just had my transmission Built, in my 2016 Camaro SS. Car was running fine broke the trans in for 500 miles and did some pulls in it. After doing the finalize tune 1-4th gear will rev out if under 30-50 percent throttle. Down shifts will hesitate dramatically at random times. Replaced Valve Body and nothing changed. Anyone ran into something similar?

    You mean, people describing a thing that happens but then not posting the files that show the thing happening? Yep, happens all the time.

    oh... you meant the transmission thing?
