I am having a friend rebuild my trans, It has a steel drum from CTS, Griner manual reverse valve body with trans brake, bolt in sprag, behind a 650 hp big block. What mods should he do? What are the clearances should he set the clutches at? What are the band adjustments? Type f fluid. Any mods to the case? Any info would be appreciated.

He is a trans guy with his own big shop.
