The speed sensor is on the output shaft of the transmission. Either it was damaged or not hooked back up.

Speedometer and odometer not working told by previous owner he replaces vss also one sensor at rear of transfer case is not plugged in is this a common problem if so what is common fix?

What make and model? It is possible that the unplugged sensor is for the speedo / odo, since the pulses for the speedo and hence the odo is picked up from the final drive on the transmission.
Note, it is only a possibility, we need more information.

Speedo not working after cable replacment

There should be a bolt and clamp holding the spedo gear housing in to the trans. If you find out there is no problem with gear. If your cable was broken and you replaced with universal cable make sure that it is long enough to be engaging into the spedo and the gear. I guess if all of that fails it would just about have to be the spedo itself. Good Luck
