Certain 2007 new body style Chevrolet Silverado and GMC Sierra light-duty pickups may indicate on the Service Parts Identification Label that the vehicle is equipped with manual transfer case (RPO NQG); however, RPO NP2 model transfer case was installed. The subject vehicles can be identified by a blue label on the lower portion of the transfer case.
The conversion back to RPO NQG transfer case usage has been completed at the plants. Refer to the VIN breakpoint information above.
If it becomes necessary to service the manual transfer case on these specific vehicles, please be aware that the NP2 transfer case requires 1.9 liters of fluid. If any repairs are required, refer to SI under Transfer Case NVG261-NP2.
