Question
Where is the speed sensor located and how do you change it?

Answer
There are two speed sensors, one on the transmission and another one which is inside the speedometer, the most common failure is the one on the transmission, it's located on either the right or left side at the rear of the transmission and has one 12mm bolt to connect it and an electrical connector on it, simple remove the connector and the bolt and pull the sensor out.
