speedometer was erratic and now sometimes do not work at all. I was told it was the VSS output on the transmission I replaced that, but still no, or erratic speedometer. odometer and trip meter only works when speedometer does.

Put a scan tool on it that can read live data and watch the data and the speedometer. If they both drop out at the same time it is either the wiring or a bad connection. If the speedo drops out but you still get the signal on the scan tool it is the dash itself. Not an uncommon issue on them.
