When a transmission requires an upshift with the prime mover operating under minimal load, the rotational speed of the output shaft of a planetary gear set in which a one-way clutch is subject to load when torque is transmitted from the prime mover to the vehicle wheels via the transmission, is monitored and the upshift inhibited until such time as the rotational speed conditions are such as to indicate that the output shaft is rotating faster than it would be driven by the prime mover. |
