Speedometer bouncing, then stopped on a 94 Econoline

Hi,

My speedometer started bouncing up and down the other day, untill eventually it stopped completely. Also the light on the selector of the automatic transmition has an overdrive button; the light of this button started flashing.
Does anyone have a clue for what this could be? It is a 1994 Ford Econoline, 5.0 automatic.

regards. Willem
