The
Merchant Automotive 10057 Transfer Case Pump Upgrade Kit with Fluid 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.
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 therefore 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.With installation of this kit, you will have a LIMITED LIFETIME
WARRANTY against pump rub.
Included Components:
- Merchant Automotive billet transfer case pump housing
- Transfer case adapter gasket at trans
- RTV Silicone
- Blue Threadlock

If
you already have a hole in your case, its recommended to install a new
rear housing for a proper repair. Lifetime warranty will only apply to
installations with a new rear housing.
