A cooling and lubrication system for a motor vehicle drive unit includes a drive unit sump, a first mechanically-driven pump, a second mechanically-driven pump, and an oil/air separator reservoir, among other possible components. The drive unit sump holds drive unit fluid. The first mechanically-driven pump fluidly communicates with the drive unit sump, and the second mechanically-driven pump fluidly communicates with the drive unit sump. The oil/air separator reservoir resides downstream of the first mechanically-driven pump and resides downstream of the second mechanically-driven pump.
