Abstract

A device for locking an operation element of an automatic transmission of a vehicle may comprise a rotationally mounted locking comb including a locking contour configured to be coupled with an operation element. The device may further comprise a locking element, where the locking element is configured to be arranged in a first position outside the locking contour to release the locking comb for a rotational movement to allow a shifting movement of the operation element. The locking element may be configured to be arranged in a second position in the locking contour to fix the locking comb for locking the operation element. The device may further comprise a rotationally mounted set ring with a control contour for guiding the locking element between the first position and the second position.
