What can fail
In extreme cold and humid conditions, moisture can freeze at the transmission oil gauge, blocking the air vent. This traps pressure inside the transmission, forcing out the rear oil seal and causing leakage. Without proper lubrication, transmission parts overheat and seize, stopping the vehicle suddenly.
What the fix does
Dealers will modify the oil gauge pipe and modify or replace the oil level gauge to prevent moisture buildup and blockage.
