The sensor at the rear differential feeds the abs, then it goes to all other electronics; pcm, gauge panel, cruise, OH display. I believe the trans takes its clue from the pcm. Are any other components getting the speed signal? Gauge? ABS light on?

If the ABS light was on too, then there may not be a clear signal pattern out of the Speed sensor in the rear diff. You could try pulling it and see if it's covered with metal wear particles. If so, wipe them off and see if it improves. In the future you may still need to replace the sensor, but check if it's wires in the area are damaged.

I'm not sure how sensitive the trans software is, if a varying signal will interfere with the shifting. But for trans issues Mark K is the best person who would know.
