Condition

Some owners may comment about rust on the transmission fluid level indicator and the transmission oil filler tube.

Cause

Water entering through the grommet of the indicator may cause this condition.

Replace the indicator and, if necessary, replace the transmission oil filler tube on affected vehicles. Use the following procedure and the appropriate part numbers listed below.
