TCI heavy duty 904 rebuild kit will make tranny handle 550 hp

Pishta, it was some of their odd modifications and their technical support provided (or lack there of) after a low mileage failure. We were trying to put their trans back together they way they sold it. No luck getting exact technical help from their on-line support folks so i just built it a proven way and returned it to the owner.
At this point I don’t think I will be buying any TCI stuff
