## Narrative
I am having a lead frame issue. At various speeds, the vehicle will just down shift, locking the tires and causing a hazard for other drivers which could be a very dangerous situation.  I was impacted from the rear due to this occurrence. It causes extreme jerkiness when doing this which is also injurious to my back and neck and shoulders.
