I have a 2005 Limited 4WD. Late last night it broke down on me. Was running perfect when I noticed a whining noise and slight loss of power. I slowed way down and it seemed to go away, but then it felt like it down shifted and lost power. When I got out I noticed there was some smoke coming out of the hood for a few seconds. Now it won't shift out of park. The shifter moves, but nothing happens. Engine starts right up and runs normal. I was fearing a massive transmission failure with the smoke, but it is full of fluid. I have crawled under it and the linkage is moving the arm attached to the transmission when the shifter is moved. Ant ideas here?
