Beschreibung
Zusammenfassung:	A hydraulic system (HY) for a motor vehicle transmission (G) includes at least one pump (P), two pump output lines (P1, P2) for supplying a first pressure circuit (1) and a second pressure circuit (2), and an electromagnetically actuated, first pressure control valve (EDS1), the inlet (EDS11) of which is connected to the first pressure circuit (1) and the outlet (EDS12) of which is connected to a first control surface (PVC) of a spring-loaded shut-off valve (PV). The shut-off valve (PV) is configured for connecting, in a non-actuated condition, the second pump output line (P2) to the second pressure circuit (2) and, in the condition actuated via the first control surface (PVC), disconnecting the second pump output line (P2) from the second pressure circuit (2). A motor vehicle transmission (G) including such a hydraulic system (HY) and a drive train including such a motor vehicle transmission (G) are also provided.
