LOL, a F*rd, yeah right!!!!!

Is this the 1/2 ton? 4L60E trans? There is a TSB out on the 4WD switch for the new GMs. Easy to fix yourself.

It could be as simple as a leak in the vacumm line. It activates a switch as mentioned above.

True, check to see that you still have suction in your vacuum hose that leads to your front diff. I should have mentioned that 1st.

What are the specs of your truck?
