Claim 5:
6. A parking lock operating system for a motor vehicle, comprising a guide link and a latching element that can be twisted and axially displaced relative to the guide link, wherein a location of the latching element relative to the guide link defines different positions of the parking lock operating system, wherein the latching element and the guide link have corresponding sloping surfaces which are coordinated and interact with each other in such a way that the latching element is twisted in response to an axial displacement of the latching element along the corresponding sloping surfaces relative to the guide link, the axial displacement being caused by a pressure present in a hydraulic fluid supply line of the parking lock operating system, wherein the corresponding sloping surfaces are arranged such that the parking lock operating system both from a base position, in which a parking lock of the parking lock operating system is active, as well as from a transport position, in which the parking lock is active, is switched to the base position when the pressure present in the hydraulic fluid supply line is increased twice in succession over a second pressure threshold and is lowered after each pressure increase above the second pressure threshold below a first pressure threshold, which is at a lower pressure value than the second pressure threshold.
