Replacement
CAUTION: While replacing the speed sensor, be sure not to allow dust and other foreign parliclos to enter into the trans-mission.
'1. Disconnect the connectors for the drive pulley, the driven pulley, and the secondary gear shaft speed sensor.
2. Remove the 6 mm bolt from the transmission housing, and remove the drive pulley. the driven pulley, and the sec-ondary gear shaft speed sensors.
3. Replace the O-rings before reinstalling the drive pulley, the driven pulley, and the secondary gear shaft sp€ed sen-sors.
