A system and method of compensating for torque converter slip in a motor vehicle include measuring rotational speeds of an engine crankshaft and mainshaft, as well as measuring operating temperatures of a fluid associated with the motor vehicle. Engine output torque is adjusted as required by controlling some combination of ignition timing, intake air flow, fuel injection, and accessory load. A system and method for deactivating a torque compensation system retrieves a number of times the torque compensation system has been activated over a set period. If the number exceeds a predetermined number of activations, the torque compensation system is deactivated.
