The speedometer on my wife's '95 Taurus (automatic, 3.0 L v-6) went crazy on the trip to Boston this Thanksgiving. I noticed that I was going above the speed limit and was being passed by everyone. I plugged in the GPS and found that the speedometer was reading about 10 mph fast at highway speeds. Also, above 65, it would occasionally drift up 10 mph then back, accompanied by a grinding noise.
It sounded to me like the speedometer cable had broken and was occasionally catching the loose ends. This happened to a car of mine about 30 years ago.
The question is, does a '95 Taurus have a speedometer cable or is it all electronic? If it's a cable, I can replace it, but if it's an electronic problem, I'll probably have to take it into the shop.
Thanks for any help you can give,
Paul
