Re: Please; need help from the fine Chevrolet people here!
Larry, the way the auto 4x4 works is each wheel has a speed sensor and when one wheel is spinning faster on one side the computer activates auto 4x4 and will engage transfer case. To test you'll need to have all 4 wheels of the ground and select switch in Auto mode. once the rear wheel speed is greater at one wheel the front will engage.My take is that if you can manually engage 4x4 High Its likely the Auto is working.
