Speedometer Out, Shifting Hard!

[gschellens]

Speedometer and odometer are not working, and the truck, 96' F250 7.3L (automatic) is shifting very hard. Everyone I have talked to has said VSS, which I replaced (this is the sensor on the rear Diff. correct?) and am still having the same problems. Also, the overhead cab lights are not working and the OD light flashes. Any Ideas?
thanks
Geoff

Check your fuses and check the wire from the VSS to the PSOM.

Overhead cab lights that are inside the cab? What was the fix??
