What's your speedometer doing? Acting up? How's the trans shifting? How's the cruise control working?

Your Vehicle Speed Sensor (VSS) may have gotten crudded-up with metallic "sludge" in the rear differential.

The VSS is the thing with wires going to it on the top of the rear-end. Take it out and clean it for a start. It may also need to be replaced, but they're relatively inexpensive.

It's a cheap place to start diagnosing.

I vote for VSS as well. Had it happen to me. Speedo went nuts and O/D light flashed.
