An apparatus is adapted to assess the performance of a vehicle's powertrain. A microcomputer collects sensor data indicative of the rotational velocity of an output shaft and a transmission input shaft and of the pressure of a directional clutch and a speed clutch. The microcomputer calculates a set of powertrain parameters based on the collected sensor data and produces an error signal in response to predetermined conditions of the powertrain parameters.
