The Merchant Automotive 10604 263XHD Transfer Case is an upgraded replacement for your 2001-2007 GM 6.6L Duramax with push-button transfer case operation. Built for increased durability, and reliability, Merchant Automotive has addressed common failure items in the factory case.
Merchant Transfer Case Pump Upgrade
The GM transfer case use a gear pump inside the case that is driven off the mainshaft. 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 Automotive Pump Upgrade to alleviate these "Pump Rub" issues.
Magnetic Drain Plug
Help extend fluid life, and the life of your transfer case with the Merchant Automotive magnetic drain plug. The drain plug catches debris instead of circulating it through the case. Also included is a fill plug made of high strength corrosion resistant stainless steel.
Merchant Automotive Transfer Case Oil
The included Merchant Transfer Case Oil is specially formulated for your GM transfercase to reduce wear, increase shifting performance, increase component efficiency, and increase driveline performance by reducing clutch chatter.
