@ Kunkel- Have checked governor pressure for Transgo tech support guys. It is approx 1 psi per MPH, rises and falls smoothly according to speed. From everything I've read this is normal.
@ JohnRR - No delayed reverse engagement. The trans works great aside from 2-3 shift.
@ bronzebee - no idea how many miles were on the trans. It was a builder with the OD fried that I bought and rebuilt, so any VB wear is unknown and completely possible.
@383man - Broke the original front drum while pressing new bushing in (d'oh!), replaced with a good used unit. Not sure this matters but may be pertinent to know
