Hello djgorillaman,
If there is anything we can look into for you (warranty/recall questions, follow up on an appointment with a dealership), we can be reached at socialmedia
gm.com (include a brief summary, the last 8 digits of your VIN, and your name and contact information).

Just replaced my encoder motor after reading this thread given your description of the problem. My truck would not shift out of 4wd until a hit a big bump or put it into park then reverse. I had a grinding noise, slipping of the transmission when I gave it gas and pulling to the right (under throttle). It is now working like a champ again! Thanks!

I have a 2006 4x4 silverado ext cab and when I have it in 4x4 auto and turning on dry pave it seems to bind up like it is in 4x4. I thought that when you are in auto 4x4 it is only suppose to be in 4x4 when the wheels spins, My truck has been doing this sense it was new, is this normal?

Hello waffie,
Did you ever get this checked into by your dealership while it was under warranty?
