I have a 99 dodge caravan. The problem started a few months ago. When I started the car, none of my gauges worked and there was a box around all of my gears (PRND3L). Then when driving while this was going on, my transmission would not shift. I just reset by disconnecting the battery for a while. All was well for 2 months. Now it is doing it again. I've replaced the i/o speed sensors and the PRDN3L/range sensor and the problem still persists. Do I need to take the car to the dealership and have the pcm reprogrammed or is it something else?
