Includes Our Transfer Case Pump Upgrade:The GM transfer cases use a gear pump inside the case that is driven off the mainshaft. The pump forces oil to the planetary as well as the drive sprocket sleeve. There are 5 tabs around the housing that fit into spots in the rear housing to position the pump. Over time, the pump can start to wear on the rear housing. This issue is referred to as "pump rub". Our Transfer Case Pump Upgrade resolves this problem. Protect your investment by preventing this condition.
Comes with Magnetic Drain Plugs:Magnetic Drain Plugs catch small debris and help extend fluid life. Kit contains a Magnetic Drain plug and a new fill plug made out of a high strength corrosion resistant 304 Stainless Steel.

Is my 1999 to early-2007 transfer case a NP261HD or NP263HD?
The easiest way to know the difference between transfer cases installed in 1999 to early-2007 GM trucks and SUVs is the shift selection mechanism. Both Chevrolet and GMC trucks and SUVs using NP261HD transfer cases use manual shift selection with a floor mounted range selector. Trucks with electronic (push button or knob on the dash) shift selection are equipped with the NP263HD transfer case.
