Hey everyone.
i got a buddy that did the 896 pcm swap in his 98 vette. The pcm came from a 2000 silverado 2500.
His issue is when he flashes the corvette OS to the 896 motor and everything works great. but transmission is acting up like not selecting gears properly, Falling out of gear.
If he loads the silverado tune, Tranmission works totally fine but motor obviously doesn't run correct.
Any ideas?
