Abstract:
1. A system for at least partially de-aerating a hydraulic fluid in a transmission, the system comprising: a plurality of transmission components; a first reservoir for receiving de-aerated hydraulic fluid; a first pump in communication with the first reservoir and operable to pump the de-aerated hydraulic fluid to the plurality of transmission components; a second reservoir for receiving aerated hydraulic fluid from the plurality of transmission components; a third reservoir for receiving aerated hydraulic fluid from the plurality of transmission components; a second pump in communication with the second reservoir and the third reservoir and operable to pump the aerated hydraulic fluid from the second reservoir and from the third reservoir; and a separator for receiving the aerated hydraulic fluid from the second pump and operable to de-aerate the aerated hydraulic fluid and communicate the de-aerated hydraulic fluid to the first reservoir.
