I bought this truck used about one year ago. Since then I have not had much time to use it. In the last three months I have had some time to drive it. Three times in those months this issue has occurred. Luckily they all occurred on my property and no damage happened except to the truck. First time it happened an exterior mirror was knocked off, a running board was bent, scratches and dings to the to the paint, and a tailight was damaged. This all happened in reverse due to a gate opening I was going through. The motor all of a sudden had a massive spike in RPMs and a violent lunge and slide of the vehicle. I learned later that it was due to a flawed part in the transmission called a molded lead frame. Transmission is Fords 6R80 6-speed automatic. Last time it happened was on 09/16/2026. It has not been inspected by any entity because apparenty I live too far in the "boonies" for anyone to come this far but the vehicle is available for inspection upon request.
