Iwas looking in my April issue of Corvette Fever and on page 61 I saw the TCI 5-Pinion Planetary for the 4L60E. It says it increases the torque capacity by 25% and its a direct bolt in.
Does anyone have one of these? I am wondering what kinda power these things can let my A4 handle especially combined with a B&M tranny cooler. What would be the next weak spot in the A4 if the tranny is staying cool and has a stronger planetary gearset?
