    Abstract: Shift arrangement for a motor vehicle gearbox. The shift arrangement has a shift element which can be connected or is connected to a shift member. The shift arrangement has a hydraulic actuator by means of which the shift element can be moved in a first shifting direction and in an opposing second shifting direction. The hydraulic actuator comprises a double-acting hydraulic cylinder which has a first cylinder port and a second cylinder port. The shift arrangement has a hydraulic circuit which has a pump and is connected to the first and second cylinder ports. The pump is connected to an electric motor as a pump drive and is embodied as a bidirectional rotational pump which has a first pump port which is directly connected to the first cylinder port, and which has a second pump port which is directly connected to the second cylinder port. The shift element can be moved by changing the rotational speed and/or the direction of rotation of the electric motor.
