How to build 4l80e for high torque engine I have a 1998 Chevy with a 12 valve Cummins and a 4l80e the motor is just a bit over stock and I am wondering what needs to be done so the 4l80e can handle high torque like around 800 ft/lbs if i ever decide to turn up the motor i don’t know much about transmissions, but i would figure a triple disc tc, shift kit? And a new billet input shaft? If anyone can tell me what exactly I should do

Triple Disc for sure
Sonnax 300m input shaft
Use a valve body that applies the overrun clutch at all times. My transbrake valve bodies do this, otherwise the sonnax Part No. 34200-40K works great on a stock valve body. I'd highly recommend it for your use
Then a quality rebuild to cover the other normal aspects of a build
