Abstract
A clutch assembly and charging system combination for use with an automatic transmission includes a clutch assembly having a clutch that is movable between a clutch engaged position and a clutch disengaged position. The clutch assembly further includes a clutch piston that is engageable with the clutch for urging the clutch toward the clutch engaged position, a clutch piston chamber in fluid communication with one side of the clutch piston, and a compensator chamber in fluid communication with an opposite side of the clutch piston. The combination further includes a charging system having a fluid circuit that is in fluid communication with the clutch piston chamber and the compensator chamber. The fluid circuit is configured to receive exhaust oil from the transmission, and to charge the clutch piston chamber and the compensator chamber using the exhaust oil.
