Im currently running a z code t-5 and shes been whinning for a few years now, it just keeps getting worse to. Still shifts fine but with over 500 ft lbs Im on borrowed time. Hoping it lasts me this summer. Anyway my cousin has a used tko 500 that accepts the stock style clutch which I like. Should this tranny be tough enough for my setup? I never ever power shift, hardly ever go to the track, but I do like to get on it all the time!
