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

What fails in the TCI...go after that components maker. C'mon if the Firestone tires suck and fail on the Explorer, is Ford to blame? Well..maybe. Disclaimer: I own nothing from TCI
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.
