The in and out flow of air can be characterized as transmission breathing. This requires the transmission operating fluid be changed periodically.

What does a transmission case vent do?

Transmission Breather Evaluation 2019-26-0339 Breather assembly is mounted on transmission to maintain the pressure equilibrium inside transmission.

What is the hose on top of the transmission?

This hose is a vent hose for the transmission and would not be connected to anything. The vent is used by the transmission so it will not build up internal pressure and push oil out of any seals.

Does a transmission have a vent?

All transmissions have a vent to maintain equal barometric pressure inside of the transmission. If the vehicle is driven through water (as in a flood) and the water level is at or above the vent, the water will cool the unit lowering the internal temperature and water is drawn inside of the transmission.

Where is the vent tube on a 700r4 transmission?
