I have a 1995 Pathfinder LE 4WD. When I start it up, the automatic transmission starts in second and will not shift automatically. If I manually shift it with the gear selector, first gear is unavailable. However, once I get it rolling I can put it in neutral, turn the ignition off and then back on and it starts shifting perfectly normally, including first gear. I have to do this now every time I drive it. Turning it on & off while it is not moving does not make it shift correctly. It has to be rolling for that trick to work. Also, it will sometimes shift correctly on startup if it is really cold outside, but never on a warm or hot day.
I searched The Garage and found no thread describing this or similar transmission issues. Any idea what the heck is going on here? All help is appreciated.
