Abstract: An apparatus for venting a transmission is disclosed which provides a transmission breather for allowing pressure equalization between the interior and exterior of a transmission while reducing or eliminating fluid expulsion from the transmission due to bridging of a fluid film across the breather. The breather includes a standpipe disposed within a housing which contains a filter. Air, transmission fluid, mist, and vapor flow through the standpipe and through the filter which captures the fluid, mist and vapor while allowing filtered air to be vented to the environment through at least one aperture in the housing. The filter facilitates coalescence of the transmission fluid which is returned to the transmission via at least one space formed between the standpipe and the housing. In one embodiment, the breather is mounted to a shift bar housing of the transmission.

Abstract: A filter comprising a casing having a hollow body and a closed end and an open end, a cartridge including a filter element, said cartridge being generally toroidal and having an end member with circumferentially spaced integral spring members extending generally axially thereof into engagement with the inner surface of the closed end of the casing, and a closure member closing the open end of the casing and yieldingly urging said filter element toward said closed end against the action of said integral spring members.
