A machine (100) comprising a transmission (114), an engine (102) adapted to apply power to the transmission, and a hybrid motor (118) adapted to apply power to the transmission. The machine includes an electronic control module (124) that controls the hybrid motor to apply power to the transmission and an engine torque sensor (125) associated with the electronic control module. The engine torque sensor senses engine torque and sends engine torque level signals to the electronic control module. The electronic control module monitors the engine torque levels and controls the hybrid motor to provide hybrid torque levels to counteract the engine torque levels.
