Default 4L60E WOT/Shifting problem
Hoping this might be something someone has already run into...

LY5/4L60E swap. PSI did the ECM/TCM

Light throttle, it seems to up-shift OK, though sometimes it up-shifts late (especially under moderate throttle).

WOT it drops back into 1st and won't up-shift. Seems to drop back into 1st even when the trans had already gone into 3rd or 4th.

Any ideas before I take it up tot he local tranny shop?
