performabuilt problem 4l60e
 

Transmission returned to Performabuilt as well as local shop. Tranny has been ruled out as the problem.

Now I'm focusing on wire mess under steering wheel. Cuts, splices, you name it.

The transmission won't go into od. Performabuilt stg 2 with 2500 stall. It shifts When manually shifted through computer, but will not shift on it's own. Factory transmission had all gears. I'm waiting to hear from Vince at Trifecta to see if tune could be the issue. Anything else I could try in the mean time?
