Abstract
A work vehicle includes a plurality of vehicle drivetrain components, a plurality of state sensors and a variable flow conditioning hydraulic fluid source. A control manifold includes a plurality of control valves to control flow of conditioning hydraulic fluid to the plurality of drivetrain components to lubricate and cool the drivetrain components. A controller receives the state signals and is configured to selectively open one or more of the control valves at least in part in response to the one or more of the state signals to provide flow of conditioning hydraulic fluid to lubricate and cool any of the drivetrain components which are in an active operating state and to close one or more of the control valves to reduce or prevent flow of conditioning hydraulic fluid to any of the drivetrain components which are not in an active operating state.
