A method for shifting a transmission from a current gear to a target gear following release of an accelerator pedal, the transmission having first and second clutches for alternately connecting and disconnecting a power source and first and second input shafts, respectively, first couplers for alternately connecting and disconnecting a transmission output and a first set of gears driveably connected to the first clutch, and second couplers for alternately connecting and disconnecting the output and a second set of gears driveably connected to the second clutch. The steps include disengaging the first and second clutches, using a first coupler to maintain a drive connection between the output and the current gear, determining a target gear, using the target gear to determine a preselected gear, actuating a coupler to produce a drive connection between the output and the preselected gear, and engaging one of the first and second clutches such that said clutch driveably connects the power source to the output through said coupler and preselected gear. |
