Vehicle is at 88k miles. Vehicle has hard shifting/delayed shifting between 1-3 and 5-7 gears. At highway speeds, vehicle tries to downshift from top gear. Have lost rpm's while driving-lasting about 3-5 seconds before engaging the gears again. Took to a dealer, was informed it was a "known" issue and would need the transmission replaced. Extended warranty will not cover since it is a known issue. No warning lamps or messages in the display center. The loss of rpm's and delayed shifting issues could cause stalling and put me and others at risk with possible loss of power/motion while moving. Especially while driving on the highway.

Ford installed parts into transmissions that are the reasons for certain years 2017-2022 models with the 10R80 transmission to fail. Ford has since remanufactured the same parts to prevent this problem with models after 2022. Ford refuses to admit it was their manufacturing defect, but will repair your transmission at a hefty cost to you when Ford vehicles with the affected transmissions fail. There are numerous TSBs (technical service bulletins) stating that Ford is aware of the problems that occur with these faulty transmissions. Ford will only post these TSBs on its website and not mail them out to consumers; the consumers have to find them for themselves. There are videos online clearly explaining the problem. I am leaving links to both of them. https://youtu.be/4SQjPinDAm0"si=k14FHcC-VV3WHelg https://youtu.be/H1Rl97OUOa4"si=wO1KmxWX2jNStXmV

Since buying my Ford 2018 F150 Raptor, I have had constant issues and problems with the 10R80 Transmission shifting irradictly, harsh engagements, stalling between gears while losing power, loud metal noises in the transmission/under the truck, and damage already done to the transfer case and transmission resulting in a truck that needs a new transmission, CDF, and transfer case. I have had this truck worked on 8 times on the transfer case, and constant reprogramming of the PCM because the technicians at the dealerships did not know how to completely fixed it and just followed the TSBs that were given by Ford. Most of which they just reprogrammed the PCM and the adaptive learning program which Ford said it was most likely causing the issues. In 2023 they found damage inside the transfer case with metal bore damage and two valves, which they replaced, it worked for a year, and now my transmission is completely damaged permentaly from not solving the initial issues. As of October of 2025, the new TSB 25-2474 and TSB 25-2475 which addresses replacing the entire transmission and/or CDF. Of which Ford knew the whole time. This past month I was almost in 7 accidents due to the transmission shifting suddenly, not shifting at all and stalling going through an intersection with cars behind me, and Ford told me this whole time that the harsh shifts were normal or desired in these performance trucks. I have three kids under the age of [XXX] who ride with me in this truck, and almost risked their lives trying to fix these issues and almost involved in accidents from the transmission failing. The transmission and transfer case/valve bodies have been worked on at least 6 times under warranty, but now it just expired and Ford is stating they cant do anything now because it is expired, yet it is now completely broken. Ford is quoting 12,000 for a new transmission, transfer case, and CDF Valve. Even though they did not fix the original issues this whole time.

While attempting a left-hand turn across two lanes of oncoming traffic, the vehicle experienced a sudden and total loss of motive power. Upon acceleration, the 10R80 transmission slipped out of gear, causing the engine RPMs to spike (rev) without transferring power to the wheels. This left the vehicle momentarily stationary in the path of oncoming traffic, nearly resulting in a broadside collision. After a delay, the transmission violently engaged, causing the vehicle to lunge forward with enough force to spin the tires and nearly cause a loss of steering control. There were no prior warning lights, "limp mode" indicators, or messages on the dashboard before or during the failure. The vehicle was taken to a Ford dealership, where technicians confirmed a failure internal to the 10R80 transmission. The service department stated this is a "known issue" with this transmission model and recommended a full replacement. This failure represents a significant safety hazard due to the unpredictable loss of power in high-stakes driving situations.

My 2018 Ford F150 only has 30,500 miles on it. There is a well known issue with the 2018-2022 Ford 10 speed transmissions, where the CDF drum fails and causes many transmission related issues. I started to show symptoms of this failure, very rough shifts from 1-3 gear, transmission would hesitate and not shift into the next gear, sometimes it would even aggressively downshift while just maintaining vehicle speed. The symptoms quickly got worse. I ended up stuck at a light because after it turned green, my vehicle wouldnt move, and i notcied it was stuck in 7th gear. I tried to manually downshift, but it wouldnt, as cars behind me were honking at me as i held up traffic. Eventually i started to accelerate from a stop in 7th gear, and then the transmission slammed into 1st gear. I brought my truck to Ford the next morning and they diagnosed it as a failing transmission with internal issues that needed to be replaced for over $13,000 dollars, reduced to $9800. This is at just 30,000 miles. I called around to other transmission shops and found a shop that would rebuild the transmission for $5000. I picked the truck up from the dealer to bring the the transmission shop, and it was just plain dangerous to drive. It downshifted from 4th to 1st going around a turn overrevving the engine, constant delayed shifts and rough shifts. I felt very unsafe driving this vehicle in this condition. All of these symptoms are amplified when the weather is cold and the transmission is still warming up. Ford knows about this issue, and has many Technical service bulletins related to the issue and how to diagnose it. Most recent is 25-2126 which is from March 31st 2025, I actually found it on the NHTSA website. Surprisingly there were no warning lights or anything that showed up, but i know others with the same issue have received warning lights. Ford would not provide any asssistance with the repair as my vehicle was less than 2 months out of my extended warranty end date.

I have a 10 speed transmission in my 2018 f150. I started noticing harsh shifting and came to fine out it is from the known issue that ford has acknowledged. The cds clutch drum slipped do ti fault parts. I contacted ford and they refused to help and said that my vehicle was out of warranty even though they acknowledged the service bulletin they stated that there was no recall at this time. I had to pay over $8,000 out of pocket and be without a truck for over a month.

Engine is ticking and whistling. Drive train issues cam phasers was told beginning of the problem

- Howard, OH, USA

This vehicle has the 10R80 10 speed transmission, the same transmission that is in the Mustang that is under recall now. That was reset at a Ford dealership in 2023 I believe. It was not acting up at that time, they "fixed" it then while it was in. Now a few years later this problem is VERY PERSISTANT now, constantly missing, skipping, and losing power trying to accelerate trying to get on to busy roads and highways, it loses power and skips through all the gears from 1st to 10th back down to 4, then 6 then 2 then back to 9 and 10. I have almost been hit numerous times from this action. It is also causing the dash lights to turn off and come back on. Also effecting my 4 wheel drive, it will not engage. This should be a SAFTEY RECALL and Ford needs to take of it.

Ford has issued multiple TSBs regarding THE DEFECTIVE 10R80 10-speed automatic transmission, particularly in F-150s (2017+). The issue is around the CDF drum in Ford F-150s (and other vehicles with the 10R80 transmission) is a known issue where an internal bushing can slide, causing significant fluid pressure loss, erratic shifting, and potential transmission failure, especially in models from 2017-2023. Ford was aware of this because they released multiple bulletins, and they even redesigned the CDF drum with JL3Z-7H351-B to fix the problem, but never issued a recall notice. I was leaving my house, and my truck did not move. It revved up to 5 thousand rpms, and then a loud bang noise happened, and then the truck moved. I took it to the dealership, and they said the CDF drum failed, and now they quoted me $7,000 to fix the known issue. When I called Ford to ask for some sort of assistance, they responded that I should have purchased the extended warranty. This is not right that they knowingly have a defective part and are refusing to issue a recall or offer some sort of financial assistance. I drive a 2018 Ford F-150 XLT 5.0L that has no mods or ever been tuned or modified; mileage is roughly at 121,000.

At 50k miles the transmission started to have a hard time finding a gear at low speeds, often -??in neutral-?? - between gears for 1-2 seconds and on occasion up you 5-7 seconds. During this -??neutral-??, the engine could still rev freely and often built revs too high for the next gear, causing a hard -??jerking-?? motion when the next gear is engaged. This proved to be moderately dangerous when merging into traffic with propulsion being cut. At 52000 miles, 10th gear would have trouble holding at highway speeds and would disengage for that same 5-7 second gap, only to eventually resort to 9th gear. Being left powerless on the highway can be extremely dangerous if you are caught traveling up a steep grade or passing another vehicle. At 53000 miles, the above mentioned 10th gear symptom arose at a steady 70 mph, and when 9th gear was engaged the dashboard illuminated a wrench icon with a message that said -??maintenance required-??. I could tell that the truck was operating at reduced power at this point. After researching the issue, I discovered the problem to be the CDF drum failed - an internal component that requires a full transmission rebuild. This problem appears to be an issue that plagues not some, BUT ALL 2017-2023 10r80 at some point in their life cycle. An extremely costly fix at that.

Ford Consumer Affairs was sent a letter with this information, too. My 2018 F150 truck had issues with the 10 speed transmission. It-??s been jumping, skipping gear, down shifting for no reason. Yesterday, 12/28/25, we were returning home from a holiday trip on I-95-??s left lane of the highway when the truck down-shifted from 10th gear to around 3rd or 4th gear spiking the RPM to over 5,000 RPM-??s for no reason on 3 different occasions. We had to move to the right lane after the 3rd time due to the wrench light coming on and the transmission temperature gauge maxed out at super hot and turn on the hazards due to only doing 50 MPH in a 70 MPH highway until we could exit. This was dangerous in so many ways due to the volume of traffic on the highway. Downshifting that much instantly was like slamming on brakes with no break lights. We were verry lucky not getting rear ended and causing a possibly tragic situation. Thankfully, we did not get into an accident. There were a lot of cars on the road, as many families were returning home. This is happening all over the USA with the 10 speed transmission and may eventually cause a tragic accident on the road. We took it to the Cocoa Ford Dealership on 12/29/25 and the diagnostic paper states they 'performed a KOEO Self Test and found PQ7F7 for Gear 10 incorrect ratio. Verified fluid vented out of top of transmission. Tech Rec Overhaul. All one time use parts and rear main seal. Trans cooler. Due to parts/labor cost recommend assembly replacement.'

The truck had a horrible shift from 3-5 that makes it hard to even get up to speed correctly and when getting up to around 2.5k-3k rpm it seems to slip makes a loud bang and the catch again and continues to go. It makes the truck annoying to drive and also feels like it-??s just going to completely give out one day
