The next thing to check then would be the pick-up/sending unit on your transmission where the signal originates, plug connections, broken or shorted wiring from the transmission unit to your cluster, possibly even your car's computer could be a problem, etc...
Hope that give you some more ideas and places to check.
Good luck.

If the speedo does not work but the odometer works, the problem is inside the cluster. If both the speedo and odo do not work, you either have a broken wire(s) or a faulty speed sensor in the end of the transaxle. These were usually a broken wire close to the transaxle near where the right side half shaft comes out of the trans. It also could be a problem inside the trans., but that is very rare. This is not a very accessible spot to check wiring, but it is the most common problem.
