what kind of durability up grades can i do to the trans with out removing the trans ,shift kit? trans cooler? what else can i do to ensure the life of my tranny thanks for all input .....ooo by the way my goal is only 12flat thanks :biggrin:
Shift kit and cooler is about all you can do without removal. I would recommend a billet forward drum. As soon as you start firming up the shifts the forward drum is the weak link.
