I am not sure what is going on with my car....all of a sudden when I was driving my speedometer went from saying I was traveling at 55 mph to 0 mph. However, the car did not lose power. It also rebounded and bounced up and down for a bit then settled down, ran fine for awhile ...then it started jumping again. Is this a loose connection? a sensor? or just something as simple as a fuse? I just had the rear main seal replaced and with it I had 2 of the transmission mounting bolts replaced. In fixing that could they have inadvertently caused this problem.
