10603 Merchant Automotive Transfer Case - GMC/Chevy 6.6L Duramax 2001-2007

Overview

The Merchant Automotive Transfer Case is an upgraded replacement for your 2001-2007 GMC/Chevy 6.6L Duramax LB7/LLY/LBZ 2500/3500 truck. 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 case 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, which 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. This kit includes 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.
