Abstract
A system for de-aerating fluid in a motor vehicle transmission includes a first rib in a first compartment of the transmission, a second rib spaced apart from the first rib, and a third rib spaced apart from the second rib. The first rib and the second rib define a first channel with an inlet region, and the second rib and the third rib define a second channel with an outlet hole. The second rib is positioned between the first rib and the second rib and has a vertical height that is less than the vertical heights of the first rib and the third rib. As the temperature of the fluid rises, the fluid flows into the inlet region, rises up the first channel, flows over the second rib into the second channel, and out of the second channel through the outlet hole.
