I own a F-250 super duty 1999 and the speedometer sometimes bounces around. This happens at any speed, and in no particular situation, and is intermitant. I have brought it to the dealership and they changed the sensor on the differencial, the ring inside the differencial, checked the cluster, all the wiring relating to the speedo, but it is still doing it. They are stumped. And now when the speedo bounces around the transmission shifts to neutral and shifts back when the speedo stops going crazy. HELP.
have the same problem?
