Abstract
A method of operating a hydraulic retarder including directing fluid from a retarder pump to the retarder when the retarder is turned on. Fluid from a main pump is directed to a torque converter, which fluid is directed to at least one of a lube operation, a tank or a cooler when the retarder is turned off. Fluid from the main pump by way of the torque converter is directed to the retarder when the retarder is on, but not filled, and to the tank or the lube operation when the retarder is filled.
