Is there just one speed sensor on the tranny or is it one at the wheels? I don't have any CEL or other lights lit up so I doubt a computer scan will be much help.
Ok, the speedometer quit working this morning without warning. Later in the afternoon it moved but would read 90 mph when you were doing 60 mph or 20 mph when you were stopped at a light. The truck has 59k on it so the warranty is long since gone. Has anyone had experience with this? Any...
