A transfer case and hydraulic clutch assembly for a motor vehicle driveline include a hydraulic fluid circuit in communication with a cavity disposed opposite a piston from a clutch pack for delivering pressurized fluid to the cavity for biasing the piston towards the clutch pack thereby activating the clutch. The transfer case and hydraulic clutch assembly also include a lubricant fluid circuit that is in communication with the chain that links the input sprocket to the output sprocket during use, as the chain rotates around the input sprocket and output sprocket, the lubricant fluid drips from or is sprayed from the chain. At least part of this released fluid is captured by a screen disposed above the hydraulic fluid reservoir. The screen removes any metal particles or debris and then passes the screen fluid into the hydraulic fluid reservoir thereby replenishing the hydraulic fluid reservoir without resorting to a time consuming and costly maintenance procedure.
