I am looking to buy a Bullitt proof automatic transmission for my 98 Ram1500 4X4. I bought one from a company out of FL called Maddog Transmissions but I don't think they are in existance anymore. I bought this truck fro the 2nd owner who had the tranny rebuilt but to me it's not pulling and shifting right. I'm running 4.56 gears with 35X12.5R17 Radial Mud Rovers by Dunlop. Any help out there?
