Abstract
A clutch assembly and a torque converter assembly having a clutch assembly, for an automotive transmission, are provided. The clutch assembly includes a clutch plate and a piston or pressure plate configured to selectively engage the clutch plate, the piston being movable between an applied position and a released position. An annular seal is disposed adjacent to the piston, wherein movement of the piston and hydraulic pressure causes the annular seal to move between a sealed position and an open position.
