Abstract: A method for shifting a semi-automatic powershift transmission used in a motor vehicle during a manually triggered traction upshift involves the shift phases of the charging of an actuator of a clutch to be engaged, an overlap of the charging of the actuator of the clutch to be engaged and the emptying of an actuator of a clutch to be disengaged, and also involves an engine rotational speed alignment. The charging, the overlap and the engine rotational speed alignment are carried out simultaneously. In the shift process during a manually triggered shift, the driver perceives a change in engine rotational speed with only a minimal delay after the shift command.
