摘要：
A torque-transmitting mechanism control valve disposed between a hydrostatic source of pressure and a torque-transmitting mechanism is effective to direct fluid pressure to engage the torque-transmitting mechanism when a control pressure is present, effective to retain the valve closed when source pressure is present but control pressure is not, and to retain the valve closed when torque-transmitting apply pressure is present and source pressure is not and control pressure is not present.
