What can fail
In cold, humid conditions, frost can form at the transmission oil dipstick where the breathing mechanism is located. This buildup can create pressure inside the transmission case and push out the oil seal, causing oil to leak and transmission components to overheat.
What the fix does
The oil dipstick breathing mechanism is modified to prevent frost buildup and pressure accumulation inside the transmission case.
