Abstract
A transmission sealed low leak controls system includes a controls system having a first fluid for operation of the controls system provided by a first pump at a first pressure. A transmission input shaft is provided. A planetary gear set is connected to the transmission input shaft by a clutch assembly. A second pump provides a second fluid different from the first fluid for cooling and lubrication of the at least one clutch assembly at a second pressure lower than the first pressure. A torque converter is connected to the transmission input shaft. The second pump further provides the second fluid to the torque converter.
