The present invention provides a transmission case assembly adapted for use with a motorcycle. The transmission case assembly includes a transmission case having a gear chamber adapted to contain a lubricant and generate a lubricant-laden mist during operation of the motorcycle, and a breather chamber in fluid communication with the gear chamber. The breather chamber is adapted to separate the lubricant-laden mist into lubricant and vapor and drain the separated lubricant into the gear chamber. The transmission case assembly also includes a transmission case cover coupled to the transmission case. The transmission case cover includes at least a portion of a passageway in fluid communication between the breather chamber and ambient air outside of the transmission case assembly. The passageway is adapted to exhaust the separated vapor outside of the transmission case assembly.
