During driving, the transmission began hesitating when shifting from 4th to 5th gear. Then in stop and go traffic, it would shift hard from 1st gear to the point my head would slam into the headrest. I would then get a notice on the dashboard of a power train failure. Once I turned the vehicle off, the notice would disappear and the vehicle would begin to shift normally for a while, before the hard shifting would continue. On the freeway, sometimes when the vehicle tried to down shift, it would hesitate and I was concerned I would be rear ended as it would not speed up. I brought the truck into 2 different ford dealerships and they both said it needed a new transmissison. There is 123,00 miles on this 2019 Ford F150. I had also related to the dealerships that there was a rattle when starting the vehicle and they said it is due to the cam shifters or more and a complete engine tear down was recommended. At the same time, the electronic screen would sometimes freeze, turn off when driving or not turn on initally. The dealerships said this needed to be replaced. The estimates for repair were from $16,461 to $13,686.

On May 5th 2025 I had a routine oil change tie rotation on my 2019 f150, 77,000 miles. There was no visible signs of transmission fluid leak or transmission issues. The week of May 15th 2025 i started experiencing hard shifting random downshifting without notice.So I immediately contacted crossroads ford of sanford NC to bring it in. There Was zero transmission fluid, so they did a full transmission service at only 77,000. Which made the problem worse Turns out, it was a bad CDF DRUM. My endurance warranty denied my claim.Which should have been covered. This cost me $8,600 out of pocket. It came out of nowhere, the downshifting with no notice a warning is extremely dangerous!

Vehicle has just over 62,000 miles on it and is just out of warranty. On [XXX] I was driving home from Colorado and the 10r80 transmission hesitated downshifting for a few seconds when climbing a hill and let out a very loud banging sound which shook the whole truck. Shortly after, the transmission tried to downshift and upshift on it's own repeatedly and would not transfer power at all. I quickly shifted it into neutral and pulled to the side of the road. This was really sudden and happened with no warning at full highway speeds(75 mph) on [XXX] southbound. If my wife would have been driving, I am not sure she would have been able to react as quickly. She wouldn't have realized what was happening. This could have easily resulted in a serious or life threatening accident. The leaking fluid also caused a sigificant amount of smoke on the underside of the vehicle as it dripped on the exhaust system. I quickly shut the vehicle off realizing it could catch on fire, but someone may not realize this as a possibility in the moment. I currently have the vehicle at a local transmission shop who has rebuilt several of these Ford 10r80 transmissions. His opinion, which will be verified by the teardown process as he rebuilds it, is that there are several common failure points which should have already been recalled by Ford in these transmissions. #1. The CDF drum which holds the clutch packs is machined in a way which allows the seal to slip and cause falure. #2. The valve body is know to wear prematurely which causes movement and leakage contributing to failure. #3. The high pressure pump is also a known failure point which can cause downstream shift issues and failure. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Transmission slipping in multiple gears, and early shift shudder. Random acceleration in low gear shift point

The 10 speed transmission had two occurrences where it failed. The first was while driving the transmission went into neutral on its own and would not go into any gear. The vehicle was towed to the dealership for a new computer part before it would operate again. The second time was when I was pulling the truck behind my motorhome but this time it went from neutral into gear in its own. The vehicle was towed this way for the previous 4 years without incident. The vehicle became a safety hazard because it broke down both times where it could not be moved. A tow truck was used both times to get the vehicle out of the road. There was no warning before this happened both times. Ford had to replace the computer module the first time and the whole transmission was replaced the second time. Warranty covered the first and I had to pay $10,000 for the second repair. Since I had this happen I have talked to several people that have had the same happen to them.

1)It was determined to be a defective CDF drum in the transmission was replaced by an independent service center. 2)The defective CDF drum started causing erratic and hard shifting. The most dangerous issue was when it would try to shift into 9th gear but indicated a shift for first gear on the display. It acted like it was deciding whether to shift to 9th or 1st but doing neither. The wrench icon would pop up on the display and I put on the brakes. If it would have shifted to 1st going 55 MPH it could have caused injury to myself and others. 3) No accident happened so I did not report it to any authority. I capped the shifting to 7th gear max. 4)I had the service center inspect the vehicle and they determined the CDF drum was bad and the transmission needed to be repaired or replaced. 5)a warning light wrench icon lit up on the display after it indicated a shift to 1st gear instead of 9th gear going approximately 55 MPH. Other symptoms were harsh shifts from 1st to 3rd gear skipping 2nd gear and other rough shifting throughout the range.

Timing chain and gears need to be replaced. Check engine light came on. This should not be happening to a newer vehicle with 100,000 miles on it. I looked up other complaints and multiple people have filed complaints about the timing chain going out on their vehicle.

Harsh and rough automatic shifting while transmission is cold. Diagnosed by dealership as bad CDF drum brushings. Recommend new transmission.

- Leesburg, VA, USA

Transmission has erratic behavior. Several times it would not downshift or would hunt for a proper gear with the 10 speed automatic transmission at intersections and when making turns with oncoming traffic. Very dangerous. I have decided to park it. Dealer said it needs transmission replacement.

- Gilbert, AZ, USA

The transmission failed in October 2023 on my way home from work. Brought it to a transmission place and had another one put in. Cost $6k - The truck is now at another mechanic as it broke down again while driving home from work - transmission and engine this time. Mechanic says needs new transmission and timing chain kit - Cost $10k This is a truck that has 100k miles on it and only 6 years old. This will be the 3rd transmission. It is a safety risk as I have no control when the transmission gives out whether its on a highway or one of these country back roads.

Merging onto highway, the transmission stayed in-between gears and did not allow me to accelerate forcing me to ride the break down lane momentarily. I had to shift to N and then back to D to regain acceleration. As continued to the next exit the transmission shifted from 7 to 1 and then back to 7 causing a hard shift and a violent jolt of the vehicle. This happened in 9th gear as well before reaching my destination. A wrench icon was on the dash and the Ford app showed a "Powertrain Malfunction/Reduced Power" warning. There have also been countless hard shifts prior to the incident above. If there was no break down lane while merging, I would have been a hazard to the traffic on the limited access highway and may have caused an accident due to the low speed and no acceleration. I have a service appointment on Sept 04, 2025 with the dealership I bought the vehicle from. (Not a Ford Dealer)

My truck started shifting hard and I took it to a shop and had to pay over $7000 due to my transmission going bad. I bought the car and had a lifetime power train warranty on it and ford stated they would not cover it still. So I had to pay over $7000 out of my pocket due to their mistake

Transmission blew up and skips

- Shrewsbury, MA, USA

In July 2025 my 2019 Ford F150 began to have hard shift changes, unexpected downshifts and other shifting issues especially in 4th and 8th gear. Then during the first week of August I pulled out at an intersection and when the truck shifted into 4th gear it lost all power however the engine was still running. Thankfully no one was behind me as this could have caused a serious accident resulting in the loss of life for those involved. It slowed down to approximately 20 mph then suddenly regained power and lunged and shifted up to 5th. This happened several times so I took it to the local Ford dealer and they said the transmission was defective and needed replacing. The truck-??s mileage was 129,000 and they said it was not covered by warranty and that even though Ford was aware of the numerous problems with the 2017-2022 10R80 transmission they refused to issue a recall and instead issued several TSBs (Technical Service Bulletin) to the dealers. It costs me $8699.72 to have a remanufactured transmission installed and has the improved CDF drum which was part of the defective transmissions Ford used in 2017-2022 in their F-150, Ranger, Expedition and Explorers. Ford knowing and continues to endanger the lives of its customers that operate these vehicles built between 2017-2022 by refusing to issue a recall for the known 10R80 transmission problems and it is costing these customers thousands of dollars to repair what Ford should have done in the first place. NHTSA must investigate these issues and mandate Ford issue an immediate recall and fully reimburse customers who have paid to have their transmissions replaced.
