The gears are shifted by means of two brushless DC clutch actuator motors, which each actuate a gear selector drum via a two-stage transmission ratio. Both of the gear selector drums are identical and each have one shift slot for moving the selector forks. As a result of using the gear selector drum principle, no additional mechanical lock is required in order to prevent more than one gear being engaged at the same time in the same sub-transmission in the event of a fault.
