Abstract: A selection system for an automatic motor vehicle transmission has a manual selector element which is locked or released by an oblique locking surface as a function of operating conditions. The oblique locking surface divides the manual forces of the selector element into a force component directed in the operating direction of the selector element and into a force component directed transversely thereto. Only this transversely directed force component can act upon additional locking surfaces if their surfaces have not yet been disengaged by an actuator arrangement before a manual operating force is exercised on the selector element.

Abstract: A selection system for an automatic motor vehicle transmission has locking system in which a toggle lever arrangement is connected with the selector element and is arranged to be movable thereby relative to a locking body. The locking body is arranged to be movable into the moving path of the toggle lever arrangement into a locking position which locks it and out of this moving path into an unlocking position which does not lock it and can be driven by the actuator arrangement for carrying out its movements. As a result, the selection system can be securely unlocked also by low forces of an actuator arrangement.
