Why Choose An MA Transfer Case?

Is my 2001 to early 2007 transfer case an NP261XHD or NP263XHD? 

The easiest way to know the difference between transfer cases installed in 2001 to early 2007 GM HD trucks is the shift selection mechanism. Both Chevrolet and GMC trucks using NP261XHD 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 NP263XHD transfer case.
