converter is kinda the heart of the whole deal. stock ones barely stand a chance against a stock motor. they just turn too much of that torque to heat. heat is the enemy. lu clutch is pretty weak to begin with and after so many on and off cycles the whole front of the converter flexes weakening it more. I know the billet is expensive, but doing it again is also. Good valve body or kit yours properly and the trans should be set for a bit more power and some towing. beef up the band apply strut also. I cant emphasize enough the stock stamped steel converter will bite ya if ya mod/tow heavy tho.
