The V6 transmission did not support the power from the 4.8 L. There is a video showing the destruction of all the gears when I decided to do a pedal to the metal takeoff so I had to upgrade the gears to V8 gears now the transmission could handle the power, but if you find a T5, that’s V8 it will hold the power
