sstockton said:What mods are you running? How many miles does it take you to eat one? Do you keep having the stocker rebuilt, or are you buying rebuilt ones, if so from who? Heat is the major killer for these transmissions, I highly recommend that you install a trans temp gauge and see how hot you're getting. It may be time to replace the stock transmission cooling system, as well as install a more efficient converter. The stock torque converter generates a lot of heat. The builders listed in Bouncers Post above are a good place to start. Down in Tx, you could probably get relentless Diesel to build you a good transmission.
