I had a deal a year ago where I took it out of 4l and it just flatlined. I got some grinding noise at some point and couldn't get it to drop into anything. I put it in neutral and got it back into 2. I took it in to get looked at and the dealer found zilch zippo. It never ever did happen again.

On the other hand it responded beautifully this last winter when I hit slick conditions on a nearby winding road which caused my truck to begin going sideways into a ditch with the back end leading. I calmly switched into 4l while still under some momentum and drove out like I was pulling away from a stop sign. So I still view the system as reliable, but I still have allot I'd like to know about it. Mechanically and electrically.

I always hear that it needs to be stopped and put into neutral to go from ____ to ____ but experience says that it isn't necessary.
