What is a transmission vent?
Breather allows the transmission to breathe air when the air inside transmission expands or contracts due to heating and cooling of lubricating oil during vehicle running. Breather allows the hot air to escape and cool air to enter into the transmission to prevent overheating issue.

Seals are generally not happy with a lot of air pressure on them, so they put a vent on the box to equalize pressure changes, due to temperature and barometric pressure.
What is the function of the transmission in a car?
