Put a shift kit in there. I love the heck out of my TransGo HD2. I did the kit, accumulators, servos, and plate. I not putting down big numbers yet, but it's on the way.

The shifting is night and day difference, no more slipping.

 

tranny shops charge out the *** for a re-build too sometimes. im lucky i have a friend in ATC ( automotive school) and his tranny teacher re-builds everything for free, as long as you buy the parts.
