When i replaced my stock one it was still in good working order, Just knew sooner or later it would dump. I had Coaltrain build me a complete trans. Its got billet input shafts so i can get away with light boost launches. I also got a 3 disk billet t/q. I only wish mine was more tight and dropped less rpms under light throttle. Give them a call, I got mine for a great price and it was tested to 600hp.
