Had the typical issues going into OD without lifting but never a lockup issue until now. Just had a billet rebuild done after breaking a flexplate and now it hunts lockup after 20-40 miles of freeway driving.
Replaced before or after rebuild:
Batteries/Leads
Governor
Pot Mod
Trans temp sensor
Brakelight switch
With OD off it does find around town 99% of the time and does not hunt lockup. Does not hunt lockup for the first 20-40 miles. Hunts lockup on freeway with TPS stock and pot mod hooked up. Trans runs no hotter than 160. I do not want to band-aid it with a switch, other people borrow this truck and don't need shafts laying on the ground.
Alternator next? Solenoid issue? TCM?
