When the vehicle is driven continuously under extremely cold temperatures (-22 degrees f.) and high humidity weather conditions, the transmission breathing (air) vent can be blocked due to moisture freezing at the oil level gauge. If this occurs, pressure inside the transmission case will increase and push out the rear oil seal, causing transmission oil leakage. The lack of lubrication can burn the internal components of the transmission, cause the transmission to seize and the vehicle to come to a sudden stop.
Risque: Sudden stops without prior warning can cause vehicle occupants to be thrown around the vehicle and cause loss of vehicle control which can result in an accident.
Solution: Dealers will modify the oil gauge pipe and modify the oil level gauge (dipstick) or replace it, depending on the type of dipstick in the vehicle.
