Speedometer issue jumping up and down on a Ford F-150 Lightning?

Hi recently My Ford Lightning speedometer has been jumping up and down while driving. Not sure what else it could be it's not the Cluster, Not the wiring nor the Cable. It's not the speed Sensor or Transmission Sensor. I also can't get any codes from my readings. Not sure what to checkout now any advice is appreciated Thanks!

How do you KNOW it's not one of the things you have listed? Just because you are not getting a fault code DOES NOT mean the unit is not faulty. If you don't know what you're doing, STOP DOING IT! Take your car to a REAL mechanic and pay to have the system checked by someone who DOES know how to troubleshoot and determine a cause for your problem.
