Ok I'm about to rebuild my Trans. It's going to get a billet input, billet triple disc, towing vb from Revmax and all the other smaller billet pieces. I've been planning on buying the rebuild kit from Revmax with the red alto power packs so it adds extra clutches, but I'd like everyone's opinions first. At the moment I probably only have 350hp but soon I'll me bumping it up over 500. This truck will do it all, dd, tow, see some sled pulls, and take a beating on the street. Any input would be greatly appreciated.
