hey brainaic Ford guys ...



is it possible to upgrade a 92 Ford V-8 Diesel Truck 3 Speed Automatic Transmission with a 4 Speed Automatic Transmission ... just swap it out and go. I want to increase fuel mileage by having the engine tack lower with a better gear combination available for use.



Not cheap, $3000 plus shortening your driveshaft:
