later model dodges run the speedo off the antilock tone wheel---the electronic sensor where the old tranny speedogear is talks to the computer about the shifting--------but i dont know the year it started in use----it could be as simple as the tone wheel sensor being bad/wiring damaged....



I believe 1998 was the first year for the differential sending unit. His VSS is attached to the transmission much like the old cable units.

I'm sorry I don't know any more, neither of my units has malfunctioned yet. One just rolled past 325,000 miles.
