TRANSAXLE OIL INTRUSION OILY APPEARANCE ON DIC

SUBJECT: TRANSAXLE OIL INTRUSION - I/P CLUSTER - (REPLACE VSS, CABLE CLUSTER)

VEHICLES AFFECTED: 89-90 CHEV 'J' W/3T40, 5-SPD W/2.0, 2.2, 2.8, 3.1

If an owner of a 1989 or 1990 Chevrolet Cavalier with a cable driven instrument cluster has a concern of an oil appearance on the face of the cluster or possibly on the drivers shoe, this may be caused by transaxle oil intrusion up the speedometer cable and into the vehicle.

If inspection shows that this is the cause, consider the following:

1. Is the transaxle vent tube restricted? If so, repair as necessary.

2. Is the transaxle fuid at the proper level? If so, repair as necessary.

3. If Steps 1 and 2 do not resolve the condition, replace the vehicle speed sensor, speedometer cab e, cable housing and cluster.
