Abstract
A method for controlling a gear shift of a dual clutch transmission having an offgoing clutch and an oncoming clutch, includes using torque transmitted by the oncoming clutch to control torque at a transmission output, using a speed of a power source to control a transfer of torque between the offgoing clutch and the oncoming clutch, and varying said torque capacity to produce a target slip across the oncoming clutch when the shift is completed.
