The tranny will have a brand a new triple disk convertor put in it... but other then that not much done to the tranny, once it goes out I will probally put a 5 speed in it... whats thecheck to see if he tabbed the KIller Dowel Pin (KDP) or pulled it out. See what up grades are done to the tranny. If the tranny is stock it wont last long with those mods. See if its built up any. That would be good
