I just rebuilt my own(at 125K) with converter and valve body from Dunrite. Used friction parts and gaskets from a local trans supply shop. I am very happy with it, and no slipping with my EDGE Juice with Attitude, exhaust, intake, and few other minor mods. If you have the know how or a trans shop you trust to use parts you supply, I recommend this option. MUCH cheaper than Sun Coast or ATS units.
