Why not? I am strongly considering it when I go 4l80 so I can stop burning up my rear tires.

The 03+ are open like a one leg rear axle. They modulate torque front and rear by using the ABS and Stabilitrac, not mechanically.
Why no AWD?
If you really want an AWD case, get the NP149. It is what the C3 and early Denalis had. It isn't open.
