search bullitproof tranny here or on yahoo for company site. You can buy torque convertors, and other components. They are your best bet cause some people have had problems with the sport shift tranny. Realize that the more power u have the more stress on the tranny, which is really just an economy car tranny, nothin special. Mine might be already slippin and i only have maybe 150@engine, 110 whp. Another idea, which i want to do, is get a mobil 1 tranny flush...best s*** out there plus maybe some Redline ATF fluid. U might be good with that actually.
