Driving the 96 yesterday out of the blue the speedo stopped working.
Got in the car again today...the speedo is working again.

I 'assume' this must be a loose wire or something. I am looking for ideas on where to start trouble shooting

1. Is there a physical speedo gear in the trans I can check to make sure is securely mounted into the trans?
2. I believe the car is drive by wire so I assume there is no direct speedo connection to the back of the dash?
