ISSUE
Transmission fluid may leak between the radiator transmission oil cooler and the transmission oil cooler fitting (NOT the cooler line into the fitting),
which may result in a residue of transmission fluid on the radiator tank around the transmission oil cooler fitting. This may be caused by insufficient
thread sealer on the transmission oil cooler fitting.
NOTE: THIS TSB DOES NOT APPLY TO TRANSMISSION FLUID LEAKAGE AT THE TRANSMISSION LINE TO TRANSMISSION OIL
COOLER FITTING.
ACTION
Install O-ring W705181-S onto the transmission oil cooler fitting. The O-ring is designed to seal the leak and reduce the possibility of transmission fluid
leakage. Refer to the following Service Procedure for details.
SERVICE PROCEDURE
1. Verify that transmission fluid is leaking between the transmission oil cooler and the transmission oil cooler fitting (NOT the transmission cooler
line fitting into the transmission oil cooler fitting). Refer to Figure 1.
