Abstract

In accordance with an example embodiment, a transmission may include a housing, a plurality of gears, and an input shaft having a vent with a first opening at a first end of the input shaft and a second opening at an outside diameter of the input shaft. The vent allows air flow between the interior and the exterior of the transmission. A breather tube may have a first opening positioned within the vent and a second opening positioned outside the vent. The first opening of the breather tube can be smaller than the first opening of the vent. A vent cover may be positioned over the second opening of the vent. The vent cover may have a first opening offset from the second opening of the vent.
