In the disclosed embodiment, the system has a gear housing and an oil reservoir in juxtaposition, with a separated wall therebetween, and a metering channel in penetration of the wall. A gear in the housing throws oil from the lower portion of the housing (i.e., the sump) upwardly to lubricate a meshing gear, bearings, and seals, etc., and to discharge some of the oil through the wall separation into the reservoir. As a consequence of the latter, the oil level in the sump is transformed from a high static level to a lowered, dynamic level in which only the teeth of the oil-throwing gear contact the oil. The metering channel insures that the housing will have some oil constantly supplied thereto from the reservoir, while the latter gear is throwing oil, and that the static level will subsequently return when the gear is halted.
