ABSTRACT:
A filter assembly capable of being directly mounted to a transmission housing or to a structure other than the transmission housing. The transmission housing includes a cavity, or groove that receives a sealing device, which is used when the filter assembly is to be directly mounted to the transmission housing. Both the transmission housing and the filter assembly include threaded portions in communication with additional grooves, or chamfers that receive additional sealing devices. For remote mounting, hoses, having coupling devices, are attached to the threaded portions such that the filter assembly may be attached to the structure other than the transmission housing.
