Auto or M6? And as the above post implies, what tires? On street tires and an unpreped surface, you are not likely to break anything as the wheels will simply spin before enough torque is applied to do damage. The 4L60 is not really very strong in stock form but is easier on the rear end. An M6 car will break the rear end before the tranny breaks. It's more an issue of traction than HP in either case though. If you use race tires on a track, a stock tranny and rear will eventually break even with a stock motor.
