T-19 leaking from rear? Mechanic can’t find the seal?
Gear oil from T-19 leaking and overfilling the Doug Nash Overdrive bolt on unit. My mechanic can’t find the seal or part to fix this problem, anyone know what I’m dealing with? I think it is the rear seal of the transmission right before it bolts on to the overdrive unit.- Kingralph88
