Look on the back side of your transfer case. There you will find a red and silver metal disk about 2 or 3" in diameter. It will have the transfer case model number shown. I have a 2500HD the 6.0 liter and I believe mine is Model number 261HD.

Hope this helps.

i just found this on four wheeler's website:

 

The latest developments in transfer case technology include hybrids that combine full-time and part-time functions in one unit. Shown here is GM’s NVG246, otherwise known as the Autotrac system. It uses a number of sensors and its own computer to direct torque when in full-time mode, plus it has the traditional part-time 4-High and 4-Low modes as well. The Autotrac system is found on fullsize GM trucks and has made its way to the midsize TrailBlazer and Envoy SUVs.

 

still don't know if that means thats what i have though?

 

i'll check that metal disc tomorrow, thanks.
