1. A transmission (1) for a motor vehicle (2), comprising a transmission housing (3) with an interior space (4) and an oil sump (6);
at least one rotating transmission component (5a) arranged within the interior space (4) of the transmission housing (3);
at least one compensating tank (7) configured for collecting oil from the interior space (4) of the transmission housing (3), the at least one compensating tank (7) fluidically connected to the oil sump (6) via at least one return (8); and
a valve (9) arranged at the at least one return (8),
wherein the return (8) delivers a predefined oil flow back into the oil sump (6) as a function of a rotational speed and a torque of the at least one rotating transmission component (5a) during operation of the transmission (11) via opening of the valve (9), and
wherein the valve (9), in a resting state when the at least one transmission component (5a) is not rotating, switches into a closed condition in order to limit draining of the at least one compensating tank (7).
