SERVICE INFORMATION
The manual transmission in some of the affected models listed above may leak gear oil from the breather vent at the engine wall. This condition does not
require a transmission overhaul to correct. Use the following Parts Information and Service Procedure to repair incident vehicles.
NOTE:
Before performing the Service Procedure, be sure to check the transmission gear oil level -- an overfill condition could also cause this incident. (If
vehicle is cold, the fluid level should be about 3/4" below the fill plug threads. When warm, it should be about level with the threads.)
PARTS INFORMATION
Note:
The breather tube kit listed below is the same part used on 2WD vehicles. However, when installed on 4WD vehicles, an additional rubber plug is
