2wd Disengaged Transmission while towing - have Autotrac

[the hammer]

As it turns out i was correct in my assumption based on the symptoms and signs of the problem, and hoping the dealership would have a magical code reader to find special codes I never found was a waste of time and money. They offered no help to diagnose the issue and no codes were given. Better safe than sorry, but nothing was gained from the shop. I fixed it on my own. Here's the summary:

 

They inspected and told me my transfer case was the problem, to the tune of $2000 to replace. I of course thought that was BS as usual and decided to go ahead and replace the encoder motor sensor. I followed the instructions here at fullsizechevy.com Great write up with a guy that had same issue I had.

 

Fixed the problem.

The dealers scan tool can do more than codes. If the person using it knows what they're doing they'd be doing component level function tests.

YEa I think that every time I talk myself into spending money on a diagnostic at GM locations, but it seems that of all the issues I have hed, the knowledge possessed on this forum and my own research always wins out. It has never failed. Gotta love our forum members!

Yeah and remember all the times members have thrown parts at something instead of having at least a scanner check for codes.
