The Merchant Automotive Transfer Case is an upgraded replacement with push-button operation. Built for increased durability and reliability Merchant has addressed common failure items in the factory case. The GMC transfer case uses a gear pump inside the case4 that is driven off the main shaft, this pump forces oil to the planetary as well as the drive sprocket sleeve. The 5 tabs around the housing fit into the spots in the rear housing are what positions the pump. Over time the pump can start to wear on the rear housing. This is commonly referred to as pump rub. Each transfer case includes the Merchant Auto pump upgrade to alleviate these issues. Help extend fluid life and the life of your transfer case with the magnetic drain plug; the drain plug catches debris instead of letting it circulate around. Also included is a fill plug made of high strength corrosion resistant stainless steel. The included Merchant Transfer Case oil is specially formulated for your Duramax truck to reduce wear, increase shifting performance, increase component efficiency, and increase driveline performance.
