Abstract
The invention relates to a hydraulic or pneumatic operating device for operating actuators in a motor vehicle transmission. At least two actuation cylinders are provided, each containing a cylinder housing. An actuation piston is guided therein along a cylinder axis in a longitudinally displaceable manner. Each actuation piston can be hydraulically or pneumatically loaded and is operatively connected to one of the actuators. The actuation cylinders are combined into a unit which can be flange-mounted on or in a transmission housing of the motor vehicle transmission. A sensor for detecting the position of a signal element arranged on each actuation piston is associated with each cylinder housing. An electrical interface, which is signal-connected to the sensors, is integrated in the unit, via which interface the sensors can be mutually contacted.
