ABSTRACT:
An oil pressure supply path to a transmission is changed over using a spool valve comprising a spool which displaces in conjunction with a selector lever of the transmission. The displacement of the spool is detected by an inhibitor switch. By supporting the inhibitor switch directly by the spool valve, the spool displacement position and inhibitor switch output signal always precisely correspond. Therefore, it is unnecessary to adjust the relative position of the spool valve and inhibitor switch unlike the case where these members are supported separately in the transmission.
