got a 01 and the needle mph bounces/doesnt keep up and the cruise control doesnt work. all research points to this sensor so i check out the haynes manual but it tells me absolutely nothing other than rear of the trans. got under there and found a wiring harness but couldnt find it, i unbolted what i thought it was and called ford who said that was a output sensor. he told me there was a trans one and the one i was talking about which is long and has a gear built into it. question is where the hell is it? anyone have a pic? ive been looking on the driver side rear.
