A system for supplying hydraulic fluid to a lubrication system of a multiple speed ratio transmission wherein a sharp-edged orifice (250), located in an hydraulic circuit between a lubrication circuit (147-150) and a source of lubrication, is connected to a flow control valve (248), which balances the differential pressure across the orifice and throttles the source of fluid pressure to a lubrication feed line. A lube augmentation valve (130), responsive to pressure, present when operating in forward drive, alternately opens and closes lubrication fluid flow through a second sharp-edged orifice (158) located in a line (146) arranged in parallel with the first orifice (250) and connected downstream from that orifice and upstream from the lubrication circuit (147-150). <IMAGE> <IMAGE> <IMAGE> |
