Lets see where should I start. Ok when i'm going and I put it into 4 wheel drive I don't have a problem at all. It shifts into 4 wheel drive any time at any speed with no problem when I go to shift it back into 2 wheel drive it won't go back unless I tap my front brakes and then it will go back into 2 wheel drive. Another thing I noticed is when it's in 4 wheel drive and I shift it back into 2 wheel drive that when I slow down to under 3 mph the light goes out and when I speed back up to above 5 mph the light comes back on. I tried one other thing is when I slowed down and it went out and I gave it some pretty good gas maybe 1/2 throttle or so then the light would go out and stay out. I really didbn't have to much time to play with it today but thats what I noticed. Does anyone have any suggestions on what it might be. I also have an extended warranty until nov of 06. Will thry cover this problem? I would think they would. Thanks for any replys.
