A lubrication system (300, 400) for a transfer case (200) includes a pump (240) in fluid communication with a lubricant source (243) and a power transfer assembly as well as a valve (302, 402) positioned along a fluid flow path between the lubricant source (243) and the power transfer assembly. The valve (302, 402) includes a valve inlet (306), a first valve inlet (406), a first valve outlet (308, 408) that does not restrict flow of the lubricant along the fluid flow path in a first state, a second valve outlet (310, 410) that is operable to restrict flow of the lubricant along the fluid flow path in a second state, and a control that is operable to open the first valve outlet (308, 408) in the first state and open the second valve outlet (310, 414) in the second state.
