Don't let pump-rub issues take down your 2001-2007 GM 6.6L Duramax LB7/LLY/LBZ, upgrade to a Merchant Automotive 10603 261XHD Transfer Case. Merchant Automotive addresses the common issues in the factory floor-shift transfer case, making their 261XHD a more durable and reliable choice when looking to upgrade or replace your already damaged unit.
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.

Good quality car care kit
Style: KIT
This product was specifically asked for by my adult son. Upon opening, it had leaked (it was a gift so I did not open) but he went ahead and used it. Good quality, car care product.

Not so good….
Style: KIT
On a brand new car used the citrus car wash product with the 2 bucket method and the interior and glass cleaner. The citrus product sank to the bottom of the 5 gallon bucket, despite all efforts couldn’t get it thoroughly mixed in the water. Used it anyway with the microfiber mitt - this mitt was excellent and I was satisfied with the wash (car was clean before washing except for bird droppings) except for eye irritation from a teeny splash. On to drying - the included microfiber drying towels were worse than worthless. They stuck to the surface of the car and shedded fibers all over the paint. I had to hose off the car to get rid of the purple lint it deposited wherever it touched the car. Larger chunks of lint came off the cloth as well. I used the interior and glass cleaner only on the interior of the windshield. Got in the car this AM, there was a haze on the entire windshield inner surface. Chemical Guys has excellent marketing and video tutorials but I’d recommend purchasing better quality components rather than what’s in this box. The ingredients in the wash, interior cleaner, and wheel cleaner are also not good for the environment, eyes, or skin. I wonder what the runoff from this one washing will do to our and neighbors’ vegetation.
