Abstract: An electrically controlled valve for automatically controlling the engagement of the clutch in heavy vehicle gear transmissions giving a "soft shifting" action. The position of a three way, three position, pressure actuated, directional valve is controlled by an electrically proportional and controlled relief valve which regulates the pressure on the directional valve. In the first position, the clutch is communicated to tank. In the second position, there is full flow to the clutch. In the third position, there is first a restricted flow to and then control of the pressure on the clutch by the relief valve.
