Although I would buy parts from the PATC guys in a heartbeat... For the money there are better places to spend your money IMO.
Several tranny companies that specialize in Ford 4R100's and they do it better than anybody. Where as PATC builds a trans for anything and everything.
BTS (Brians Truck Shop) Best of the best None better period! About $4000 installed.
John Wood is now offering a rebuilt 4R100 with 6.4 TC for $2900. I just don't think you can beat this deal with a stick.
Suncoast Trans. Nationwide dealer network, solid trans, lots of happy campers on this board running one.
