1999-2010 Ford New Process and New Venture NV271F Transfer Cases all use the same Oil Pump. Your NV271F Manual Shift Transfer Case will have one of two types of interchangeable Oil Pickup Assemblies. Factory assembled, early production models will have a five piece pickup assembly. Later model cases have a one piece, unitized assembly. If you have the early, 5 piece design, we still have the component parts for it, but I recommend you replace all 5 pieces with QU10973 One Piece Pickup for the simple reason it's unitized construction means it is less likely to fail.
