Long delay between shifts where the vehicle loses substantial speed

- Deslosge, MO, USA

I-??m filing this complaint regarding a major transmission failure in my 2018 Ford F-150 (VIN: [XXX] ) with just over 40,000 miles. The issue resulted in multiple loss-of-drivability incidents while pulling out into traffic. On several occasions, the vehicle failed to engage or hesitated severely when shifting into gear, leaving me stranded on the wrong side of the road. In one instance, I was forced to manually cycle through gears to try and regain forward momentum while cars approached at speed. This created a dangerous situation not only for me but for other drivers. The vehicle showed no prior warning lights or messages before the issue occurred. A certified repair shop pulled diagnostic codes and identified a transmission-related fault. I was advised to take the truck to a Ford dealership, where they confirmed a transmission failure requiring a full replacement, quoted at nearly $10,000. A transmission failure at this mileage is unacceptable and unsafe. I-??m reporting this as a safety concern due to the sudden loss of power and drive function in live traffic situations. I-??ve since found reports of similar issues from other F-150 owners. This needs further investigation and consideration for recall or formal service campaign.

Transmission failed. Specifically the CDF drum which is a known issue and Ford has a TSB for it. Truck would not move or shift gears periodically. Would also slip into neutral and would not engage any gear which is extremely dangerous on the road. Dealer confirmed that the CDF drum is shot and the truck needs a new transmission, $8800. My truck only has 53k miles on it, it is a 2018 model year. There were no visual indications of a problem, no CEL. You could tell just by driving the truck, it got so bad that it was virtually undriveable. I put the TSB below. This really needs to be a RECALL as it is super dangerous.

I was driving on the interstate, and pressed the accelerator to make a lane change and the tranmission did not respond. I could have been rear-ended because I had signaled and the other vehicle started to fill my space. I was unable to make the change. Fortunately the folloing vehicle kept a safe disance. Gear shifts have also been extremely clunky and skipping gears, sometimes when slowing down, dropping from a high gear (4-6) down to 2 or 1 without a corresponding drop in speed.

Hard shifting slamming gears needing transmission work.

- Parkersburg, WV, USA

Transmission: sluggish upshift (vehicle feels like it is being pulled backwards), hard shifting and sudden downshifts at speeds in excess of 35 mph. Narrowly avoided getting rear-ended during rush hour traffic. I have not taken the vehicle to the dealership due to being afraid to drive it. No warning lamps, but symptoms started about two weeks ago but were very intermittent and easily resolved with a TCM relearn. Symptoms are similar to the known issues with the Ford 10R80 CDF Drum issues. I will be having the vehicle towed to the service center next week for a diagnosis and way forward. On 18 June 2025, I was traveling home from work. I stopped at a red light and waited for the light to turn green. The light turns green and the line of cars (roughly 20, with the lead car approximately 5 ahead of me) begin to proceed through the light. As I passed through the intersection and began to pick up speed, my vehicle shifted into 6th gear at about 40 mph. Less than 2 seconds after shifting into 6th, it shifted down to 1st gear, lost all power to the drivetrain, and almost caused a collision between me and the car behind me in a busy residential area. Pressing the accelerator only revved the engine. I turned my hazards on and shifted the vehicle to Manual and was able to get it going again but the same symptoms happened at my next stop and have persisted since.
