Everytime I put my truck in 4X4 Low, I get a really loud "clunk." I have the push button automatic transfer. Does anyone else have this issue also? Or is it only for GMC's???

Are you completely stopped when this happens?

Yes, I have to be at a complete stop with my truck in neutral or it won't switch over. I can push the button before I actually stop or am in netural, but nothing will happen until I am total stopped and in netural. It makes the same sound regardless of when I stop or push the button.
