Beschreibung
Zusammenfassung:	A hydraulic control device for an automatic transmission for a motor vehicle includes a shiftable throttle valve allocated to one or more shift elements of a plurality of hydraulically actuated shift elements. The shiftable throttle valve hydraulically connects a respective pressure-adjusting device of the one or more shift elements to a respective clutch cylinder of the one or more shift elements. The shiftable throttle valve is shiftable into at least a first shift position and a second shift position. A hydraulic resistance between a hydraulic transmission controller and the one or more shift elements of the plurality of hydraulically actuated shift elements is larger in the second shift position relative to the first shift position.
