2014 Ford Expedition: check engine light

Filed Mar 23, 2026 · Acceleration, Transmission · TX

While driving the truck will shift into 1st gear. It will also shift back and forth between gears randomly. When this happens, the wheels may lock up or just skid. The service engine light will come on, the speedometer will drop to zero while still moving and the "miles to empty" will show at zero miles. Sometime the tire indicator will turn on as well. This may/may not reset when the vehicle turns off and back on. Other times the vehicle will stick in first gear when leaving from a stop. It will also stick in 3rd or 4th gear as well. There have been times where it seems to stick like it was on cruise control but will disengage when the brake it tapped. This all occurs anywhere between a stop position and 50 MPH. The problem has been confirmed by a shop as the "Molded lead Frame" in the 6r80 transmission.

As I was driving on the freeway my transmission downshifted and my rear wheels locked up and I lost control of my vehicle with all 4 of my children in the car with me! After this happened the check engine light came on and I had the code read at my local auto parts store and the error code was P0720 for the output shaft sensor which is located on the lead frame inside my transmission. I called my Ford dealer to get a quote to fix my car and was told based on my VIN the part number for the faulty part is AL3Z7G276D. When I looked up this part number on the internet I found that this part was recalled for the same exact thing that happened to me except that the current recall didn’t include my model year and build. I’m confused as to why if the recalled part number is in my truck and I almost died along with all 4 of my children because of it that my car is not covered in this safety recall.
