Is my 2001 to early-2007 transfer case a 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.
