An oil supply system of an automatic transmission or an automated manual transmission in a power train has an oil pan and a pressure line for supplying elements of the transmission with pressurized oil. A pumping device pumps oil from the oil pan into the pressure line at a supply pressure P0. A hydrodynamic converter, being a starting element, forms a subsection of the pressure line. A hydrodynamic retarder is disposed in a retarder oil circuit. At least a first switching valve, a second switching valve and a heat exchanger, wherein the heat exchanger is selectively switchable, by way of the switching valves, as a subsection into the pressure line or the retarder oil circuit. A temperature sensor is provided following the pumping device in the direction of flow in order to detect the oil temperature in the pressure line.
