When traveling down a steep hill at about 35 mph I shifted from drive to 3rd for engine braking, the truck went into first gear instead of 3rd and the rear wheels temporarily slid/screeched. I did it before without issues but I never did that again as I’m afraid of damaging something.
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.
Driving home today, my truck just started downshifting without warning. My truck was almost rear ended. I had about 5 min until I got home. It would take off and drive fine for a moment, and then out of nowhere drop all the way down to first gear. Very dangerous!
The contact owns a 2015 Ford F-150. The contact stated while driving at highway speeds, there was a hissing sound coming from the steering column.

The contact was informed that the front driver side wheel hub and vacuum line to the integrated wheel end (IWE) actuator were faulty and needed to be replaced. The vehicle was not yet repaired. The manufacturer was notified of the failure, but no assistance was offered. The failure mileage was 30,000.
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)

The transmission will downshift from 6th to 5th at hwy speed....it also at other times , will only go from 1st to 2nd gear and no farther...wrench light comes on each time.I have to pull off hwy and slowly try to take off to get transmission to shift correctly. A lot of times pulling to side of road puts me in a dangerous situation.When it won't shift past 2nd gear I have to try to pull over immediately as it over-revs.I am taking it to an independent service center and dropping it off for their confirmation as sometimes tranny will shift fine for 2-3 days and then go back to malfunctioning. It started this about a year ago, but I had neck surgery then and am now just getting back to driving.The wrench light comes on each time , along with the transmission fan.The truck is available for inspection any time.
Vehicle suddenly downshifts into a lower gear while accelerating from a stop or cruising at constant speed. Wrench icon comes on the dash and check engine light comes on. Turning off the engine and back on will stop the issue and restore the power.

The transmission is a safety issue and is available for inspection. The six speed automatic has a 5th to 4th downshift that is regularly rough and can be jarring at times. A few weeks ago on my way home from work while driving 30 mph around a small bend the truck shifted from 4th to 2nd on its own and bucked so hard that it scared me and brought my hands off the steering wheel and made my back sore for the next day. This is a blind bend because of the shrubbery in the front yard at the bend and it is also at the beginning of a school zone. This could've been a worse situation if there would've been a car or school bus going in the opposite direction. This was certainly the worst one yet but there have been similar situations where the truck jarringly shifted from 4th to 3rd on its own. The problem has not been reproduced, confirmed or inspected as mentioned above. I have read multiple stories stating very similar or even the same occurrences on the forums. The lead frame in the transmission seems to be the leading cause for this issue. Others have been to the dealer, had the computer reflashed and were told it just needs to relearn their driving, only to have the issue return. After seeing these stories and now reading about the investigation into the issue I've been holding off to see what happens as I do not want to waste time and money to not have the issue fixed. There were not any warning lamps, etc before or after this issue. I have noticed that when the jarring shifts occur the small area of the cluster that shows gears one through six goes black and remains that way until manually pressing the button on the shifter to make the image reappear. To this point these shifting issues almost always occur at low speeds while gently resting my foot on the gas to keep a steady speed. It feels as though the transmission shifts into fifth too early, the rpms slowly lower and then it downshifts to fourth in a jarring manner.
2015 Ford F150 XLT 2.7L, 6 speed auto, Crew CAB, short bed. Yes, you can inspect. Going down highway around 45-50 MPH, without warning or warning indicators, transmission suddenly downshifted, rear wheels locked momentarily, RPM's ran up high and vehicle slowed down abruptly in the middle of traffic. Wrench light on dash appeared and disappeared. About 5 minutes later driving on freeway, transmission would not automatically shift up to the next gear, stayed in a low gear for a minute, then finally shifted up. Vehicle is currently at Ford getting inspected. Did not drive the vehicle since the incident on 3-29-24, except to go to the Ford dealer.
Transmission malfunction by sudden downshifting to first gear at highway speeds. This caused my rear wheels to lock up and skid as if I had slammed on the brakes and temporary lose control of the vehicle, which is extremely dangerous on the highway. It has occurred multiple times. There were no warning lights the first several times this happened. They check engine light did come on after about the 6th time it occurred.
While driving at random times trans will go into a limp mode and have only 3 gear speeds. Sometimes either a wrench symbol will come up or a check engine light will come one. When this happens it’ll stay in a limp mode til ignition is cycled for it to reset. Also while at low speeds it has dropped me from 4th gear to 1st.
I have owned my 2015 F150 SPORT 2.7 ECO BOOST since it was new, and occasionally it downshift's mainly in town from 5th gear to 1st gear. I thought this was my fault until I heard about the safety concern. I have mentioned it to ford, but was told that downshift's were normal? Anyway I an now concerned this could happen on the interstate which I don't drive on regularly. Thanks [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Truck while turning right or forward will for no reason goes into lost traction(dry road) and truck downshifts and loses power. Very dangerous as there is no warning and potentially can be hit from behind since no brake lights are engaged. Recently read article that other trucks of this year and make are having same issue. I have taken into shop and awaiting what is the problem.

A few years back, I was having an issue with my truck shifting hard. I actually took it to a friend's shop and he repaired it, for about $1600. They changed a "chip" in it. The vehicle was never inspected by Ford, or the police, or my insurance company. The problem was identified by the repair shop and taken care of, or so I thought. The issue seemed fixed for a while but within the last year the issue has begun again. The transmission will not shift at times. It seems stuck, which causes the engine to rev very high. I worry about causing lasting damage to the engine as a result of the transmission sticking.
