Lube control flow valves for vehicle rear cases and differentials

A drop-in valve assembly for a lube flow control valve for an OE valve body, the OE valve body having a bore, a solenoid inlet port in communication with the bore, first and second cooler inlet ports in communication with the bore, and a first sump port in communication with the bore, the drop-in valve assembly comprising:

• a sleeve configured to be positioned in the bore, wherein the sleeve has openings configured for fluidly communicating with at least some of the solenoid inlet port, the first and second cooler inlet ports, and the first sump port therethrough;
• and
• a valve member configured to be positioned in the sleeve in the bore and to axially move therein between a first position and a second position, wherein moving the valve member from the first position to the second position at least partially reduces fluid communication from the first cooler inlet port to the first sump port and at least partially increases fluid communication from between the first cooler inlet port and the second cooler inlet port, and wherein the drop-in valve assembly is configured to block at least one port of the OE valve body when installed therein.
