1991 Plymouth Voyager

Transmission problem
1991 Plymouth Voyager 6 cyl Front Wheel Drive Automatic 125K miles

The speedometer and odometer have gone out. The needle either flatlines or bounces all over the place. Sometimes it works fine for a few seconds. The cruise control also has gone out. It seems to only work when the speedo works. Are they related? Do they work on a vacuum or elictrical. This is on a 3.3 engine and a 4 speed auto tranny. &Quot; 91 Voyager. Is this sensor related or is there a speed control issue. Once while doing about 60 mph I lost power for an instant. It happened so fast I couldn't reproduce the problem There's a can that the speed control cable goes to under the battery. Is this a good place to start? I'm disabled and need my van.
