2500HD Crew Cab

Don't know if the Crew Cab part matters but is Auto-Trac an option on this truck ?

I don't think you can get Auto Trac on the 2500HD... although I think you can get it on the 1500, 2500, and 1500HD.... you might look at gm.com for a list of options...

Cruiser is right.  AutoTrac is not an option on the 2500HD.  You can get the push button 4wd though...
