Abstract
A breather vent assembly includes a vent main body defining an internal vent passage and including a proximal end, a distal end, and an upwardly extending retainer portion disposed outward of the distal end. A cap is coupled to the vent main body and disposed at the distal end. A tortuous path is defined between the vent main body and the cap and a fluid vapor flows through the internal vent passage and the tortuous path to thereby vent the fluid vapor from a transmission. A reservoir is defined between the distal end and the upwardly extending retainer portion and configured to receive a condensate when a portion of the fluid vapor condenses in the tortuous path. A drain passage extends through the vent main body and fluidly couples the reservoir and the internal vent passage such that the condensate in the reservoir is drained back to the vehicle transmission.
