<p>A method for controlling gear shifts in a multiple speed power transmission for a vehicle that includes a first clutch for transmitting power through a first power path producing a reverse gear, and a second clutch for transmitting power through a second power path producing a forward gear. The method includes selecting a reverse range in which the transmission is to operate, preparing the transmission to transmit power alternately through the first power path and second power path; engaging the first clutch and transmitting power through the first power path in the reverse gear, selecting a forward range in which the transmission is to operate, disengaging the first clutch and engaging the second clutch, and transmitting power through the second power path in the forward gear.</p> |
