2019 Ford F-150

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.

The contact owns a 2019 Ford F-150. The contact stated while driving at various speeds, the vehicle made an abnormal banging sound, and the transmission was slipping. There was no warning light illuminated. The contact stated that while at a complete stop, the vehicle failed to shift into gear for an extended for a while. The contact waited for the vehicle to respond as needed. The dealer and the manufacturer were not notified of the failure. The vehicle was not diagnosed or repaired. The failure mileage was approximately 125,000.

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)

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.

The contact owns a 2019 Ford F-150. The contact stated that while driving 60 MPH, there was an abnormal sound coming from the vehicle. The vehicle failed to accelerate as intended while depressing the accelerator pedal. The contact continued driving; while driving downhill, the vehicle slowed down unintended.

The contact shifted to 4-WD, and vehicle functioned properly for a short while. The contact stated that the message "Service Engine Soon" was displayed, and the “WRENCH” warning light was illuminated. The vehicle was towed to an independent mechanic who diagnosed that there was a voltage issue with the solenoid in the transmission. The vehicle was not repaired, because the codes were cleared. The contact was advised to take the vehicle to the dealer for the software update. The vehicle was taken to the dealer, and the software update was performed. The contact stated that on a separate occasion, while driving at a slow speed, there was an abnormal sound coming from the vehicle. The vehicle then went into LIMP Mode. The contact was able to pull over to the side of the road. The message "Service Engine Soon" was displayed, and the “WRENCH” warning light illuminated. The vehicle was towed to an independent mechanic, where it was diagnosed that the solenoid and unknown valves had failed. The contact was informed that the transmission needed to be replaced. The vehicle remained at the dealer unrepaired due to the cost. The manufacturer was not notified of the failure. The failure mileage was approximately 128,000.
