Congratulations. I am over 205,000. I have had transfercase problems. My model has TOD. My suggestion would be to find a good mechanic. The one I used was not a dealer and although he did a fine job he said he would not work on it again. Apparently its a difficult system to understand. As for the dealer I have no confidence that anything they tell me is the truth. Good luck. Its a fine automobile. I love everything about my car except the fuel milage.
