Beschreibung
Zusammenfassung:	The invention relates to a transmission device for a motor vehicle, comprising at least one coupling unit (S2a; S2b; S2c), which has a friction-closure unit (13a; 13b; 13c) and a form-closure unit (14a; 14b; 14c) connected in parallel with the friction-closure unit (13a; 13b; 13c) in order to connect two coupling elements (S21a, S22a) in a rotationally fixed manner, a first hydraulic and/or pneumatic actuator (15a; 15b; 15c) for actuating the form-closure unit (14a; 14b; 14c), a second hydraulic and/or pneumatic actuator (16a; 16b; 16c) for actuating the friction-closure unit (13a; 13b; 13c), and a directional control valve (17a; 17b; 17c) for controlling the first actuator (15a; 15b; 15c) provided for actuating the form-closure unit (14a; 14b; 14c), wherein the directional control valve (17a; 17b; 17c) has a control line connection (18a; 18b; 18c), which in at least one operating state is connected, with respect to pressure, to the second actuator (16a; 16b; 16c) provided for actuating the friction-closure unit (13a; 13b; 13c).
