Folks...I've read everything I can come up with on this Forum and others, and today jacked up my 01 Deville in an effort to locate the Speed Sensor. But completely failed. I've posted twice but no response. Can I be the only owner who has lost the digital speedo/odo/cruise control due to (probably) a bad sensor (which I could purchase for less than forty bucks) but just have been unable to find where the old one is located on the transmission. From under the car I really can't see the sides of the transmission, much less the bottom of it. Does anybody know where it is located?
