A device for control of a hydraulically actuatable shifting element of a motor vehicle transmission, having one clutch piston which defines, with a first surface, a hydraulically pressurizable piston space and, with a second surface of different size, a hydraulically pressurizable reset space and comprising a first clutch valve associated with the piston space, a second clutch valve associated with the reset space and a holding valve associated with the reset space. The valves can be moved according to a control pressure adjusted by a pressure adjuster, a change between a pressurization of the clutch piston on the piston space side and on the reset space, side being performed as a control function so that the clutch piston on its surface facing the reset space is pressurized in an unshifted state of the shifting element and is discharged in a shifted state of the shifting element.
