4L60 not shifting @ WOT 95 impala ss
Buddies impala has had this problem since his car was stock. Originally, a hypertech handheld tuner was used on it, and shift points raised, which he believed started the problem.
Since then, he has had the pcm reflashed to stock at the dealership......still didn't fix it. He had the trans built up hoping to fix the problem, and no dice.
Any ideas? We sent the pcm to solomon and he set shift points @ 5200, but still have this problem.
