The 01 - 03 trans. was rated at 520 ft/lbs of flywheel torque and the new trans. is rate at 600 ft/lbs. I believe this was necessary to handle the increase in torque output GM will be releaseing in the near furture. So yes, it will handle 80 more ft/lbs without going into limp mode. One must remember that if you add 80 ft/lbs to the new motor it will most likely go into limp as GM is rasing the flywheel torque in the new motor, but , if you've got an '04 now you can add the 80 ft/lbs and everything will adapt right in. We have run our 80 RwHp Tow program with no problems on the new transmission and the Race program at 120 RwHp and it handles it. The Race program has maxed it out so I would still recommend upgradeing if you plan to go to something greater than 80 RwHp. With the Race program you have to drive it for awhile before it adapts in properly so if you put it to the floor right away you will still hurt the new style transmission.
