ABSTRACT:
A torque-transmitting regulating system employs a valve mechanism, which distributes fluid pressure from a pressure source to a torque-transmitting mechanism by control for the engagement and disengagement thereof. The valve mechanism has associated therewith a pressure sensor mechanism, which distributes a control signal to the electronic control module (ECM) to inform the ECM of the condition of operation of the torque-transmitting mechanism. A valve mechanism supplies a first pressure signal during disengagement of the torque-transmitting mechanism, a second pressure signal during the filling period of the torque-transmitting mechanism, and a third signal during the fully engaged condition of the torque-transmitting mechanism.
