Hello,

Got a Heavy Duty master rebuilt kit from Pro Built Automatics.

My 4L60 had a dead 3-4 clutch (conical and friction material partially removed).
The sunshell was starting to crack badly so the HD one in teh kit will make it too

Question: Has anyone installed that kind of kit ? If yes what is the result in term of shifting, up and down, feeling etc ...

My car being stock and not a sport car (Buick RMW 92) I really wonder what it will be like after the MODs ?????????????

Thanks for your experience sharing !!!
