A sump arrangement for a transmission includes a first sump arranged for receiving a hydraulic fluid at a first location, a second sump arranged for receiving the hydraulic fluid at a second location, different than the first location, a transmission pump with an inlet, and a valve for selectively hydraulically connecting the inlet to the first sump or to the second sump. The transmission pump is arranged for pumping the hydraulic fluid through the transmission. In some example embodiments, the valve is a spool valve. In an example embodiment, the valve is an inertia valve.[French]
