2008 1500 Sierra transfer case is acting up. When I used to dial I can hear the actuator working under the truck. The problem is when I put it in auto it acts as if it's in four wheel High. It binds on tight turns and has all the characteristics of four wheel High. I have had another truck with Auto and it definitely doesn't do that does anybody on here have any idea what may be the cause of this. It's really annoying and I would like to have auto back as it is really handy. Long story short I got stuck the other day when we got a good amount of snowfall. I used another truck to pull my truck out which was no big deal it wasn't a hard jolt or nothing. But it is now acting as if four wheel Auto doesn't work but four wheel High and low does work
