A hydraulic operating device for operating actuators in a motor vehicle transmission has at least two actuation cylinders 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 loaded and is operatively connected to one of the actuators. The actuation cylinders are combined into a unit that can be flange-mounted on one side, via a flange face, to a dividing wall of a transmission housing of the motor vehicle transmission. The cylinder housings are injection molded from plastic integrally with a flange plate that runs transversely to the cylinder axes, the flange face being formed on the flange plate. The cylinder housings protrude beyond the flange plate, at least on the side of the flange face, in the direction of the cylinder axes.

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.
