A power train control system includes circuitry which, during the delay between the issuance of a shift command signal and the actual initiation of shift and/or during non-shifting modes of operation, monitors the outputs of sensors. If the sensors are found to be out of order, steps are subsequently taken to inhibit prime mover torque variation so as to avoid erroneous shock attenation control. The line pressure is controlled in accordance with the presence or absence of a torque variation signal to provide an improved match between the engine torque and transmission line pressure controls.
