Is the transfer case behind the Allison 1000 or ZF6 transmission in a 2001 through early-2007 truck an NP216XHD or NP263XHD?

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

How tight do I tighten the transfer case mounting nuts for the NP261XHD or NP263XHD at the transmission output adapter?

The factory-recommended torque specification is 37 ft-lbs for the transfer case adapter nuts for both the NP261XHD and NP263XHD.

How tight do I tighten the transfer case assembly bolts at the transmission output adapter?

The factory's recommended torque specification is 27 ft-lbs for the transfer case assembly bolts for both the NP261XHD and NP263XHD.

I hear a grinding noise at low speed after reassembling my transfer case. What could that be?

A low speed grinding noise is most commonly caused by the rear output bearing snap ring not being fully seated causing the bearing to move out of proper alignment. Verify that the snap ring is fully engaged and properly seated in the rear housing and the locating groove in the bearing.

What would cause a speed sensor correlation code after installing this upgrade?

A speed sensor correlation code is often accompanied by a low-speed grinding noise and is frequently caused by the rear output bearing snap ring not being fully seated causing the bearing to move out of proper alignment. Verify that the snap ring it fully engaged and properly seated in the rear housing and the locating groove in the bearing.
