Abstract

An actuator device for a motor vehicle transmission, the motor vehicle transmission having:—at least two shafts;—a plurality of gear sets for the achievement of different gear steps;—a plurality of shift mechanisms that may be operated to produce or release a rotationally fixed shaft-gear connection; the actuator device having:—a plurality of output elements that can be moved in order to operatively engage in shift mechanisms of the transmission—a main actuator device having at least one main actuator element that is movable for the engagement of gears, the main actuator element preferably being an output element—a secondary actuator device having at least one movably mounted secondary actuator element, which is movable for the disengagement of gears, the at least one secondary actuator element preferably being an output element, the main actuator device and the secondary actuator device cooperating to produce controlled relative movements of at least two output elements.
