I have the truck listed above straight 6 with a 5 speed transmission. My speedometer and digital odometer stopped working. I replaced the speed sensor on the differential and checked all fuses. Still not working.

Hello,

I would check the instrument cluster wiring connector for corrosion, but it sounds like the speedometer module is out inside the cluster. You might need a rebuilt/used cluster. Check out the diagrams (below). Please let us know what happens.
