CDF hub failure. Transmission falls out of gear or shifts really hard especially on the freeway or when turning and it-??s down shifting. Took vehicle to the dealership and Ford acknowledged the failure and they have known about it but have not issued a recall. FORD says it-??s a design flaw on their part.

While going 60mph or above, transmission automatically shifts from 10th to 1st gear! 1st gear has not locked into gear yet while doing this but if did there would be a catastrophic accident.

- Leesburg, FL, USA

The component that malfunctioned was the automatic transmission, when leaving from a full stop, I released the brake and pushed on the accelerator, and the vehicle began to move forward and shortly after that it went out of gear and stopped accelerating. The engine just revved up, I let off the accelerator and it slammed hard into gear then started moving forward again. My safety and the safety of my wife and children who were riding with me was put at risk two of the three times, as I was turning into traffic, when the car lost forward momentum from the issue, there was oncoming traffic that almost hit me one time and could have hit me another, if the car had not slammed back into gear and started moving again. I am concerned that if it does it again at some point it may not eventually get in gear again and we could be struck by a vehicle, or rear ended. I have had the problem reproduced one time by an independent mechanic who rode with me. when was looking to get it diagnosed. With out charging me to take it apart and complete a repair he said he believed based on the symptoms and common problems they see with the 10R80 transmission in these years that the CDF drum is going bad. he said it can cause symptoms like this or slipping out of higher gear and down into first causing loss of forward momentum and high engine revving. The repair would require a rebuild or replacement of the automatic transmission. I have not had the component inspected by the manufacturer because it is out of warranty and I do not currently have the funds to pay for a new or rebuilt transmission. I had no warning lamps or messages about the problem prior to the failure, but I did have symptoms of hard, and inconsistent shifts while driving, that have continued to get worse, and the independent mechanic that rode with me said these are all symptoms of CDF drum failure.

10R80 transmission have many issues regarding their shifting and the use of the adaptive tables. Have experienced multiple hard shifts, flare shifts and the occasional downshift in the heads up display. It will be in a higher gear like 7 or 6 and show it dowshifted to 1 for two seconds. Then it goes back to normal. Previous owner already had the transmission repaired and it still has the same issues. I get a code a few minutes later after it shifts horrible for a few minutes. Pointing to issues with the incorrect gear ratios. These transmissions are hazardous as it will happen randomly and will go back to normal most of the time. Have been caught at a light before where it won't shift down back to 1st. I have to put it in park or reverse for a few seconds for the transmission to find itself. Very dangerous to be doing that in traffic. Have had multiple near misses. Of course Ford just says the transmission needs to be changed out for a new one. At 9K-10K for the repair each time and frequently its absurd. The issues have to be fixed or else you are stuck buying a new transmission every 50-100K. I have 90's Ford's with the original transmission still working.

The transmission shifts erratically in lower gears. The transmission shifts erratically at highway speeds between gears 8,9, and 10. The transmission shifts suddenly into first gear at any speed. When transmission begins to shift erratically at highway speeds it causes sudden loss of power. I bought the truck from the Ford dealership in Franklin North Carolina on [XXX]. It was taken to the dealership on 22, June, 2023 for these transmission issues. It was taken to the Ford dealership again on 19, October, 2023 for the same transmission issues. It was taken to the Ford dealership again this morning on 21, April, 2025 for the same transmission issues. This time the dealership told me they wouldn-??t do anything about it even though it is under warranty. They are referring it back to the third party transmission repair shop that they sent it to the first two times. The owner of the transmission repair shop told me that he doesn-??t know what is wrong with the transmission therefore he doesn-??t know how to fix it. He told me that Ford doesn-??t know what-??s wrong with it and that is the reason they won-??t issue a recall. The Ford dealership AND the transmission repair shop both told me that Ford issued a technical service bulletin on the problem stating there are three steps to attempt the repair. Step 1; update the software in the truck computer system. Step 2; replace the valve body in the transmission. Step 3; replace the transmission. My truck has been through the first two steps but when it came to the third step, the warranty company chose to rebuild the transmission instead of replacing it.

F150 transmission randomly disengages during acceleration causing truck to quickly decelerate instead of accelerating. The loss of transmission engagement is for a period of time just when you need the most control. Our problem started approximately a month ago intermittently and has become a daily though unpredictable event. When the transmission does engage it bangs into gear or shifts erratically into different gears not related to application of foot pressure on accelerator. I took our F150 to a Ford dealer ($145 to diagnose) and an independent transmission repair shop and both called out the problem as a CDF clutch failure and that it is a known design defect by Ford that they are ignoring. Worst of all, the only fix is a replacement transmission at a cost of $9K and because the dealer has so many in line of our vehicle they said despite a redesigned transmission being available, they could not actually perform the replacement for about a month. Ford should be accountable for knowing of a design defect that results in high consequence safety risks of its vehicle occupants. This Ford transmission defect introduces a manufacture's defect safety hazard to drivers and because it last up to 30 or more seconds, it needs to be called out by NHTSA to Ford as a real safety issue with high potential negative safety consequences they should proactively address. The first time it happened to my wife it was in a true near miss with my wife turning right and accelerating onto the highway. Another vehicle did not recognize she had lost power and was heading into her flank as her vehicle went lame almost hitting her. Ford should be directed by NSHTA issue a recall. I have also attached Ford Safety Bulletin 24-2436 but note it does not raise this to the safety urgency it needs to have.

- Grayson, KY, USA

My transmission started shifting erratically. It would go from 8th to 10th gear down to 1st or 2nd gear then go back to 5th while trying to merge into oncoming traffic. People had to lock up there brakes or swerve around me to avoid a collision. There were no lights on the dash. I had a transmission shop take a look and there were no failure codes for the transmission. I have had to park the truck due to safety concerns and not drive it. This happened on several occasions during that trip.

- Pell City, AL, USA

The transmission will randomly downshift or drop into neutral while driving which has almost caused a collision multiple times. I can-??t cross a lane without worrying if the truck is going to shift into neutral and not accelerate.

- New Hill, NC, USA

The contact owns a 2018 Ford F-150. The contact stated that while driving 15 MPH out of the driveway, the vehicle failed to shift to first and second gear. There were no warning lights illuminated. The vehicle was taken to the dealer for an oil change, and the contact notified the salesperson of the failure and was informed that the issue was normal. The vehicle was then towed to another Ford dealer to be diagnosed, and the contact was informed that 8 out of the 10 clutches were burned, causing the failure of the transmission. On another occasion, while driving at an undisclosed speed, the vehicle became stuck on a hill in 7th gear. The contact stated that the failure had become a consistent failure. The vehicle was not repaired. The manufacturer was made aware of the failure and referred the contact to the NHTSA Hotline. The failure mileage was approximately 55,000.

Transmission delay in shifting and or jerking while shifting through gears. Was travelling at highway speeds in 10 gear and my transmission lost power. Could not accelerate at all transmission was non responsive for a couple seconds while showing it was in 1st gear. This happened a couple more times at lower speeds from 7th gear and downshifted automatically to 1st cutting off any power to transmission. I had made a left turn and vehicle stalled from transmission not accelerating at all and hesitated and jerked into 4th gear. Downshifting and upshifting is delayed affecting the driveability of the vehicle. Vehicle only has 63k miles on it no prior transmission issues at all. I took it into Ford dealership and they said heave seen problems like this with this vehicle in the past and right about where my mileage was at too. Ford says I need a new transmission but cannot diagnose what exactly is wrong with the transmission. Their option they gave me was $6700 to open up transmission and replace parts but the price doesn't include parts or a new transmission at $8100. In doing a little research online there appears to be a major concern with Ford/GM over the 10 speed 10r80 transmission I have. I have 3 children and do not trust driving the vehicle as the driveability of vehicle is a safety hazard and believe it's due to Ford knowingly that there are concerns over the transmission and not willing to do anything to fix their engineering issues with the transmission. The highway speed that i explained could have resulted in a crash or worse, someone getting hurt.

- Spring Grove, IL, USA

This vehicle is equipped with the 10 speed transmission. The vehicle will accelerate on its own, shifts harshly, slam into gear when placing in park, fails to accelerate, and fails to shift at times.

- Onalaska, WI, USA

We have had our Ford F-150 evaluated at least twice at a Ford Dealer and they have no idea why it shifts into neutral when the vehicle is in drive. It doesn't do it every time. Sometimes it catches and lunges, other times it just revs the engine when trying to accelerate in drive. I have almost been struck on two separate occasions attempting to pull out into traffic and the vehicle shifted back to neutral as I started to pull out (even though it was firmly in drive). This is terribly dangerous!

- Alexandria, MN, USA

- Gaffney, SC, USA

Initially my transmission was rough (jerky) changing through 1,2,3 and 4. It then on occasion lost engagement as I was driving and happened a couple of times whilst trying to make a left hand turn across oncoming traffic. Finally the transmission went altogether and went into limp mode. I took the truck to the ford dealership and they informed me I needed a new transmission. They replaced the transmission. They replaced the transmission and told me I could come pick it up. Once I picked it up I started to drive home and the transmission liquid started to leak. They had to come pick up the truck on a flatbed and repair it once more. Once receiving the truck back for the second time I drove the truck but noticed a strange noise coming from the engine, so inspected and found the engine coolant to be empty. I was able to fill it up but the ford dealer requested I take it back for them to inspect. When I did they could not find anything wrong. Then on the [XXX] while driving from New Jersey to Baltimore the transmission started to act strange. The transmission lost power in 10th gear, then regained power, followed by a bang in the rear end from the drive shaft and the the rear wheels locked up in 10th Gear at 65mph on the interstate. The wheels then released the transmission overheated up to 240F degrees and oil started leaking from the transmission.

While driving on highway at highway speeds the engine shutdown for no reason and I had to take emergency action get the vehicle out of the roadway to safety. Vehicle would not restart and had to be towed to dealer. Subsequently the powertrain control module had to be replaced. On three separate occasions on later dates, while driving on highway the transmission unexpectedly shifted from gear 10 to gear 1 for no apparent reason causing delay and high rpm and rapid deceleration. Only after third time did the transmission warning light activate. A computer check by mechanic showed the 10th gear to have unknown inertia with a drum shifting.
