My 2017 Ford F-150 equipped with the 10R80 10-speed automatic transmission experiences repeated harsh and unpredictable shifting. The transmission will hesitate or delay during shifts and then engage very hard, sometimes producing a severe bang or jolt through the truck. It also experiences abnormal gear hunting and inconsistent shifting behavior. These symptoms can occur during normal driving and create a safety concern because the transmission does not always respond predictably to driver input. Ford has issued technical service bulletins addressing harsh engagement, delayed engagement, harsh shifting, and delayed shifting on 2017-2020 F-150 vehicles equipped with the 10R80 transmission. My vehicle is experiencing these same types of symptoms. I am reporting this because I believe the 10R80 transmission in affected 2017 F-150 vehicles should be investigated for a potential safety defect.

The 10-speed transmission exhibits severe and dangerous shifting behaviors. It frequently shudders and jerks extremely hard when shifting between gears.Most critically, the transmission fails to properly engage into gear. While driving, I came to a complete stop at a red light in active traffic. When the light turned green and I attempted to accelerate, the transmission would not engage into gear, leaving the vehicle completely immobilized and just sitting there in the middle of traffic. Because the truck failed to take off and move forward, it created an immediate road hazard and almost caused me to be severely rear-ended by the traffic behind me.This transmission hesitation and failure to engage poses an immediate and severe safety risk of a high-speed collision.

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.

I have changed this transmission twice, and the truck still turns off when it comes to a complete stop at an intersection. It hesitates, skips, and pulls back when driving.

Had powertrain engine light come on in Jan 2026 and transmission would hesitate and had problems with downshifting on interstate. Fiord said no recalls on the vehicle.. I, had transmission service done and still had problems with it downshifting while on freeway. On March 29,2026 truck would not start. Message came on stating it was in drive when it was actually parked. Had to tow it in. Diagnostic test was done with Powertrain Control Module Parking Aid module Body control module etc problems reported. The same problems that other Fords were having but Ford said this truck wasn’t included. Auto shop got the part directly from manufacturer and installed the parts. Battery was low because of this and had to be replaced. Total cost $1730.64. We only have this vehicle and had to get a rental car while in shop. Also we are on a limited income on social security and therefore this put a huge financial strain on us. We and other could have been seriously hurt and truck damaged as we were on interstate 80. Itemized bill and diagnostic report is available. I am requesting Ford to reimburse me as they stated no recall and now as of April 20, 2026 there is a recall on this very issue

While driving my 2017 Ford F-150 equipped with the 10-speed automatic transmission, the vehicle began experiencing progressive slipping and delayed shifting between multiple gears, including failure to upshift beyond higher gears during normal driving. The transmission would flare between shifts and hesitate before engaging. During one drive, the vehicle would not shift properly and displayed a wrench warning message instructing the driver to see the owner’s manual. The transmission appeared to enter a reduced performance or limp mode. The issue has worsened over time despite a recent transmission fluid service and computer relearn/flash performed by a service center at a cost of approximately $1,100. No overheating occurred, but slipping continued and spread to additional gears. Prior to purchasing the vehicle, abnormal shifting and clunking were noticed during the test drive and brought to the dealer’s attention. The behavior was described as normal operation for the 10-speed transmission. The transmission has since deteriorated into failure requiring replacement. This malfunction creates a safety risk due to unpredictable acceleration, delayed power delivery when merging or crossing traffic, and loss of normal shifting operation. Independent repair facilities have diagnosed the transmission as internally failing and recommended full replacement with estimated repair costs of approximately $8,000. Symptoms began gradually and progressed to active fault behavior with warning message activation.

Transmission seems to be faulty. While accelerating the transmission will shift from 4th gear to 1st gear then up to 3rd gear. Sometimes it will return to normal operation at the point, sometimes it will continue to shift up and down at random. I have been told by the shop (more than 1) that the transmission is fine. This random and hard down shifting cause the vehicle to lose speed which is very unsafe. I first noticed the problem about 6 months after I purchased the truck (Oct. of 2024) as a hesitation when shifting from 3rd to 4th. This is an ongoing problem that continues to worsen as time goes on. Currently the vehicle is available with reasonable accommodations to be inspected.
