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.
