When the control unit monitoring the dual clutch transmission detects input signals from the driver and/or the prime mover and transmission indicating that the free-wheeling mode should be exited, then the transmission is controlled to reconnect the prime mover and the driving wheels. According to the invention, a rapid reconnection of the prime mover to the driven wheels is achieved by engaging the second, normally open clutch unit. Prior to engagement, the control unit can select a suitable gear depending on the input signals from the driver and/or the prime mover. As none of the first set of gears connecting the first input shaft to the driving wheels in the first transmission mechanism is engaged, the first clutch unit can be disengaged during or after engagement of the second clutch unit.
