摘要：

A method of actuating a shifting element with three shift positions, having a simply controlled shifting cylinder as the actuating element, a shifting element for shifting to the three shift positions and a pressure regulator, such that the shifting cylinder is designed as a cylinder with one working line and the shifting element is pushed by the spring force of at least one spring element to an end position and moved to the other shift positions in opposition to the spring force. The central position is recognized in that, when the correct shifting element position is reached, the force for moving the shifting element in opposition to the spring force abruptly increases and, because of this, a specific pressure can be set by a pressure regulator for the central position.
