A vehicle power train, an engine and a transmission having a common fluid supply provided by a pump which is driven by the engine, a pressure regulator valve that regulates the pressure of the fluid supplied by the pump and delivers excess flow to a hydrodynamic torque converter in the transmission, a valve that delivers flow from the converter to lubricate the engine and prevents flow in the opposite direction and a lubricant control valve that delivers controlled fluid flow from the pump to lubricate the engine below a predetermined engine lubrication pressure and at a higher predetermined engine lubrication pressure blocks fluid flow from the pump to lubricate the engine and then delivers fluid from the converter to lubricate the transmission.
