Abstract

A hydraulic control system of an automatic transmission includes a clutch compensator feed circuit that is in communication with clutch apply circuit exhaust fluid. The clutch compensator feed circuit receives exhaust fluid from one or more apply clutches, or other torque transmitting device(s), and feeds the exhaust fluid to the balance side of the clutch or other torque transmitting device. The clutch compensator feed circuit may be open to atmospheric pressure, such that the clutch compensator feed circuit is not pressurized with respect to atmospheric pressure.
