Yesterday my '03 RDV started skipping. At first I though it may have been my spark plugs until I looked at my gauges and realized that my tact was at 4000 rpm, and the car sounded like it was in neutral. The car began to slip in and out of gear. When I down shifted the car lurched as normal. The speedometer is not registering a speed at all. All of the other gauges are working properly. I have no idea what could be wrong and don't have the money to just send it to the shop. I don't mind doig things on my own as long as I am told what to do. The fluid levels are fine. As is the color. Does anyone have any suggestions, or experienced the same problem?
