1994 Pontiac Trans Sport Owner's Manual - Page 204

NOTICE: Spinning your wheels can destroy parts of your vehicle aswell as the tires. If you spin the wheels too fast while shifting yourtransaxle back and forth, you can destroy your transaxle. Rocking your vehicle to get it out: First, turn your steering wheel left and right. That will clear the area around your front wheels. You should turn your traction control system off. (See "Traction Control System" in the Index.) Then shift back and forth between "R" (Reverse) and a forward gear, spinning the wheels as little as possible. Release the accelerator pedal while you shift, and press lightly on the accelerator pedal when the transaxle is in gear. If that doesn't get you out after a few tries,you may need to be towed out. If you do need to be towed out, see "Towing Your Pontiac" in the Index.
