Abstract
Official abstract text for this publication.
A system for shifting a transmission includes an off-going clutch, an on-coming clutch, and an assisting clutch. A controller is configured to increase an amount of torque carried by each of the on-coming clutch and the assisting clutch. The controller is further configured to reduce an amount of torque carried by the off-going clutch and, after the off-going clutch is disengaged, to reduce the amount of torque carried by the assisting clutch.
