I have heard good things about the newer autotrac systems. I just prefer the shift on the fly version found on the Dodge Ram. I think you can still get it on the new GMs too (thank God). A friend of mine has a 2003 z71, he only had one glitch with his autotrac, but otherwise, it works fine.
They aren't going to get rid of the shift on the fly 4wd, are they? I prefer simplicity in my trucks.
What is the difference between the system used on the trailblazers and the sytem used on the silverado/avalanche? :huh:

I just prefer to shift, not push a button. Autotrack works well from what I hear, but I just don't see a switch working as well 10 years after purchase compared to the base 4wd system on gm trucks. (4low, 4hi, and 2hi with a floor mounted shifter)
