I have a 2017 SS I just put a 2019 gear reduction kit in the transmission with a new clutch. Well, i finished installed the tranny and ran in neutral for 3 mins then put in drive. It immediately lunged forward and died and stays in 1st. Not sure if i put it back together correctly or if something else is going on. The MCU has also been flashed for the gear reduction.
