Just purchase a new 2006 Avalanche. Had a couple of questions for the group.
First, why does GM not offer a 3.73 axle ratio in the 1500? You can get
3.42, or 4.10 only. The 3.73 is an option in the 2500.Second, I am still looking for a web site or publication that describes the workings of the auto mode of the 4WD system. If anyone know were to find details and theory of operation, I would appreciate a heads up.
