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.
