Abstract
The present invention provides a pressure control system having a control solenoid with plurality of coils disposed therein, and operable to provide a plurality of pressure gain characteristics to a torque-transmitting mechanism. By selectively energizing the individual coils or a combination thereof, multiple pressure gains may be achieved with a minimum of additional system hardware.
