Abstract
A transaxle for transmitting power to output at multiple speed ratios includes halfshafts having a portion located in a transaxle case and a second portion extending toward a wheel. A differential mechanism located in the case transmits power between the output and differentially to the halfshafts. A clutch driveably secured to the output and connectable to one of the halfshafts for controlling the magnitude of a speed differential between a speed of the output and a speed of the halfshaft includes a cylinder and a piston moveable in the cylinder. A hydraulic system includes a passage located adjacent a halfshaft and hydraulically communicating an inlet and the cylinder, the inlet being sealed at axially opposite sides against passage of fluid by a seal rings located in a wall that surrounds the passage.
