Ford Taurus possible speed sensor problem
A week ago the speedometer wouldn't work and the car wouldn't shift right. This happened once before and we replaced the Speed sensor and it took care of it. With the new sensor in the car, we were able to drive about a half mile then the car would do the same thing. So we replaced the clip and some of the wiring because it looked bad. Still the same thing. We also tried putting the old sensor back in and it still doing the same thing. We are stumped. Someone told us it could possibly be the computer as when it first started if you shut off the car and restarted it it would work fine. We had the transmission redone in Feb 2011 and it shifts fine unless the speedometer is acting up. Is there anything we can look at next? We are literally stumped.
