THERE IS NOTHING WRONG WITH THE TORQUE CONVERTERS, the software is over cycling the TC and overheating the clutch mechagnism, overheating the transmission pump, sending metal debris thruout the system destoying the tranny all while your under warrantee, . soon as warrantee is up the damage is done. and you just buy a new truck or tranny
if you purchase the HPT MVPi2 it can fix your trans issues and you can disable the DOD, increase idle speed to 650-700 rpm, adjust your cooling fans for optimum temp control, correct the tcc issues and do many more things like shift point adjustments. cost you $400-700 for the interface with credits to tune pre-2017 truck find a used MVPi1 for $100-200 on ebay is even better deal
