Abstract
A hydraulic control device for a transmission of a motor vehicle has a housing with a bore hole and a valve piston that is contained in the bore hole and slidable between different axial positions. The shift levels of the transmission are determined by setting the axial position of the valve piston. Prior to installation of the control device on another part of the motor vehicle, the valve piston is secured by a safety element against axial movement. Installation of the control device causes the safety element to release the valve piston.
