In 2025 my 2017 Ford F-150 started randomly downshifting. We took the car to the ford dealer who could not assess what the problem was exactly (Rowe Ford in Westbrook, Maine). They suggested a new transmission to be safe and clearly indicated that this was not a safe truck to drive at the time. We took the truck to another ford dealer to try to get an actual determination of what was wrong (Casco Bay Ford, Maine). They also advised that no codes were being given but that the truck was clearly downshifting and not safe. With no real alternatives or clear problem, we paid $8,000+ for a new transmission. Then, months later we get the recall notice: (Campaign 26S28 / the federal safety agency Recall 26V237) - Ford F-150's were downshifting... We had Ford do the software update as this is now a new transmission, but when we asked about the Recall and if there was anything we could do about the $8,000 we just paid lower and upper management (we talked to both) advised that because they could not definitively put a label to the problem before we fixed the transmission that they could not attribute the downshifting to the same problem and so will not help or otherwise reimburse us for the cost of having to fix the problem that was recalled later. No remedy was offered by Ford.

The 4-5-6 drum ring in my transmission went out on my truck that has 70, 318 miles on it. Vehicle was missing shift points and would not always shift properly causing power to not be available when expected - especially dangerous when trying to merge onto a highway. Vehicle was inspected by a Ford dealership and by ABC transmissions of Tacoma WA. I paid ABC Transmissions $9,693.98 to fix the problem. The transmissions would clunk badly and was very obviously missing shift points. They first appeared 30k miles ago but Ford lied to me saying it was a "software problem".

I am filing a formal complaint regarding improper service practices, breach of safety recall protocols, and severe resulting vehicle damage committed by Fox Grand Traverse Ford. On April 23, 2026, independent facility Kinney’s Complete Auto Repair replaced the lead frame connector on my vehicle. During service, the transmission pan was dropped and inspected. The transmission was certified clean, free of metal shavings, and operating normally. On August 3, 2026, a mobile service technician from Fox Grand Traverse Ford performed Safety Recall 26S28 (PCM Software Update) at my workplace parking lot. Ford Motor Company’s official support guidelines explicitly state: "Ford Mobile Service is unavailable for Recall 26S28." Servicing requires in-dealership PCM reprogramming and post-flash adaptive calibration. Because the service was performed in a parking lot, the technician omitted the mandatory post-flash adaptive learning drive cycle. The vehicle immediately suffered harsh shifting, hydraulic pressure spikes, and forward rolling while in Reverse. Fox Ford now demands $7,883.73 for a complete transmission replacement, falsely claiming there metal shavings in the gear box and that the damage was a "pre-existing condition," despite the recent clean pan inspection from April 2026.

The contact owns a 2017 Ford F-150. The contact stated that the vehicle had not experienced a failure associated with the federal safety agency Campaign Number: 26V237000 (Power Train); however, the vehicle was taken to the dealer to be inspected and serviced under the recall repair to keep the vehicle up to date. The contact stated that after the recall repair was performed, the transmission unexpectedly downshifted to a lower gear, and the vehicle decelerated. The vehicle was taken back to the dealer due to failure, and it was diagnosed with transmission failure and that there was oil leaking through the transmission. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 180,000.

The April 2026 recall for the 6R80 transmission (2015- 2017 F-150s) involves a software update to prevent unintended downshifts to first gear, which, if left unaddressed, can cause significant damage to the transmission and torque converter. The recall aims to prevent this damage, not cause it, though the underlying defect—if it causes violent, abrupt downshifts-can lead to transmission failure, including issues with the torque converter. The pcm tells the transmission what gear to shift into. The trs is what signals the pcm to tell the transmission what gear to shift into. I am saying all of this because I am have a bad downshifting problem almost like it’s causing the transmission to slip it has been doing this for months and I think it is causing more failure in my truck. It is getting worse and worse and this is my only reliable vehicle to get to work. I’ve called ford and they told me to keep driving but I don’t feel safe. They also quoted me for a new transmission saying the problem will occur again if I get one so I don’t get the point in doing that but I think it’s causing my transmission to go out and my torque converter to go out. I am out of ideas and don’t know what to do. I cannot afford a new transmission and it’s unfair to me that it’s their problem and I got quoted a new transmission. Also if I keep driving it and it messes up they are going to deny that that recall isn’t the problem I’m not sure what to do.

Transmission failure/malfunction (known issue), Harsh/Delayed Shifts, downshifting erratically, loss of power on the highway. I stopped driving the truck after having random loss of power going 75 mph, to having no acceleration and almost getting rear-ended twice. I took the truck in to Holmes Tuttle Ford in Tucson, Arizona to get the TCM reflashed. They confirmed the harsh/delayed shifting and told me it got worse after the reflash, but they were not able to reproduce the random loss of power. Whenever I experienced the truck going into "limp mode" there was a wrench warning lamp turning on. This is a known defect on the 10R80 transmissions, yet there is no safety recall on it. The truck has 100,242 miles on it.

I am submitting this complaint regarding the failure of the 10R80 automatic transmission in my 2017 Ford F-150. My truck developed progressively worsening transmission problems that were ultimately diagnosed as a failed CDF drum, requiring a complete transmission replacement at a cost exceeding $9,000. Before the transmission failed, the vehicle exhibited harsh shifting, delayed gear engagement, slipping, erratic shifting between gears, and unpredictable transmission behavior. The transmission would hesitate during acceleration, shift unexpectedly, and fail to respond normally to throttle input. These issues created dangerous driving conditions while merging onto highways, crossing intersections, and driving in traffic because I could no longer predict how the vehicle would respond. The repair facility confirmed that the root cause of the failure was the CDF drum within the 10R80 transmission. After researching this issue, I discovered that many other Ford owners have experienced the same failure. Ford has issued Technical Service Bulletins addressing CDF drum-related problems and has revised the CDF drum design, indicating that the original component had a known defect. This is not simply a reliability issue. The unpredictable shifting and loss of normal transmission operation present a serious safety concern that could increase the risk of a crash. I respectfully request that the federal safety agency continue investigating the Ford 10R80 transmission and the known CDF drum defect to determine whether a safety recall or other corrective action is warranted. Owners who have incurred substantial repair costs due to this apparent design defect should also be considered for reimbursement. I have retained repair invoices and documentation confirming the CDF drum failure and transmission replacement and can provide them upon request.

As of May 23, 2023 Ford issued a TSB 22-2428, TECHNICAL SERVICE BULLETIN 10R60/10R80/10R80 MHT Automatic Transmission - Harsh/Delayed Engagement And/Or Harsh/Delayed Shift - Built On Or Before 23-Dec-2022 " Ford issued a TSB and not a recall since they knew the affected vehicles would be out of warranty and they could then charge the owners pay for repair cost of $8,000- $12,000 for a new transmission replacement. Ford refuses to replace these transmission at their expense, if you are out of warranty, which I am and most are unless you have a extend warranty. How it is even legal that they aren't required by law to replace these transmission at the full expense of Ford since they clearly sold us vehicles with known defective transmission from the beginning and refused to address when the vehicles were under warranty. My safety concern is the transmission will fail in open traffic from these harsh engagement, harsh & delayed shifts. I made multiple remarks to the Ford service departments about harsh transmission problems, once around 30,000 miles and again around 60,000 miles. Ford never admitted identifying operation flaws during their evaluations. They stated transmission was operating within normal specifications.

Ford f150 10 speed transmission failure, third replacement of defective oil pan, and replacement defective rear main seal. Transmission was taken for service/repair while still under warranty. Local dealer advised problem not found. Hard shifts and skipped shifts persisted until recently I had to pay for tranny rebuild and third replacement of defective oil pan. FORD should have to reimburse me for these repairs. It is a known fact that ford knew about this problem for years and has had thousands of complaints.
