OK Roy. Here's the inside of your speedo driver. The little red gear is the motor, then the intermediate gear and then on the right, the speedo shaft and gear. Everything is dry, no lube. I would suspect a manufacturing defect in yours or some other type of damage. Possibly a bad connection or software issues. You can disassemble the driver by unclipping the four tabs easy enough. The only part that falls out is the intermediate gear and it has to be installed right side up to work. The tiny gear on the hub is visible below the red gear and it is correct in the pic. It was easy enough to reassemble. Good luck in your troubleshooting.
