Transmission down shifts while accelerating, slips when starting from a dead stop, and shifts extremely hard when shifting. It is a safety risk especially when pulling out at an intersection, as it stops (or will slip) in the middle of the intersection. It has not been confirmed by the manufacturer or dealer, only by the article from USA Today. The vehicle has not been inspected by anyone, as it just started yesterday. There were no early indications or warning signs prior to it starting yesterday (08/06/2025).

Transmission constantly shifts erratically. When this happens, the transmission gets stuck between 3rd and 5th gears and sometimes only stays in 5th gear, no matter how fast the truck is going or even if it is not moving. About half the time when this happens it causes a rough "jerk" and could cause loss of control. If you must stop at a stop sign or stop light when this happens then you're impeding traffic just trying to get back up to speed after your stop, which could lead to an accident. This also causes the check engine light to come on.

Shortly after I bought the vehicle in 2015, the transmission would frequently make a loud metal on metal sound when accelerating as the transmission downshifted from 5 gear to 3rd. I took it to the dealer several times. They said it was a manufacturers fault from a bad batch of transmissions and not something the dealer could permanently fix or was responsible for. No other indications. I am concerned the transmission could lock up and cause an accident. Date of the incidents is from November 2015 to present.

Lead body failure. Causing it to downshift suddenly when driving, higher rpm, and non-start condition.

I noticed in the fall of 2024 that my transmission stared shifting hard between 30-40 mph during acceleration. I had the local Ford dealership check out the issue and they stated I needed a new transmission and included an estimate. I decided to seek information from 2 independent transmission shops and they could not confirm that I needed the transmission replaced at that time. The vehicle has been driving fine and I recently started to notice the hard shift again at 30 mph. Every once in a while, when the hard shift occurs, it seems like I lose power to the drive train and my vehicle slows down to about 15 mph and vehicles need to go around me. It only lasts for a few seconds and then the acceleration will continue to drive normal. I do notice an increase in RPM's from time to time as well while shifting around 30 mph but does not feel like it is slipping. Once through this area of shifting, the vehicle operates normally shifting through other gears. There were no warning lights or other symptoms leading to this issue. I did notice that there was an article posted with a possible transmission issue from this year vehicle that is being investigated concerning sudden down shifting while driving. Here is the article [XXX]. I am wondering if this is part of this issue? INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
