Merchant Automotive 10382 T-Case Upgrade with Drain Plugs & Fluid, fits 2001-2007 GM 6.6L Duramax



The Merchant Automotive 10381 Transfer Case Upgrade with Drain Plugs for your 01-07 GM 6.6L Duramax is the best upgrade you can make to your GM transfer case (model 136, 146, 246, 261, 261HD, 263HD, 263XHD, 261XHD) to prevent the ever increasing problem of pump rub.

Here is the best upgrade you can make to your GM transfer case(model 136, 146, 246, 261, 261HD, 263HD, 263XHD, 261XHD). Prevent the ever increasing problem of pump rub.


What is "pump rub"
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. Because the pump is driven by the shaft, the housing of the pump must 'float' in the rear housing. 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. GM installed a spring steel clip in the housing intended to prevent wear but the clip can break and render useless

Being that the pump housing is aluminum and is a harder material then the magnesium rear housing, it can wear a hole in the rear housing and cause a very small leak. This leak is high enough in the case that it typically will not leak when vehicle is not moving and therefor not leaving any drops on the ground. Typically the condition is not found until there is transfer case damage from running the case out of fluid.

Avoid costly repairs to your transfer case by preventing this condition.

Full installation instructions are available right here on this site. Look under the Tech Information link on the home page for step by step directions.

With installation of this kit, you will have a LIMITED LIFETIME WARRANTY against pump rub. If your case ever wears a hole in the case with the upgrade installed, We will buy you a new transfer case.

Included in the kit:

  • Merchant Automotive Billet Transfer Case Pump Housing
  • Transfer Case Adapter Gasket A/T Trans
  • RTV Silicone
  • Blue Threadlock
  • Magnetic Drain Plugs
  • Merchant Automotive Sticker

If you already have a hole in your case, its recommended to install a new rear housing for a proper repair. Lifetime warranty will not apply to a case that the rear housing has been repaired.
