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.

2018 Ford F-150 transmission complaints
Page 9 of 35: complaints 221 to 250 of 1,022, newest first, as owners wrote them.
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.
The contact owns a 2018 Ford F-150. The contact stated while driving at an undisclosed speed, the transmission independently shifted gear. The contact stated that when the failure occurred, there was a hard banging sound coming from the transmission. In addition, the contact stated that the transmission had skipped gears and had independently shifted into neutral(N) intermittently. There was no warning light illuminated. The dealer was made aware of the failure and the contact was advised that a diagnostic test was needed. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The contact was advised by a member of an online forum to contact the federal safety agency Hotline to report the known failure. The manufacturer was not made aware of the failure. The failure mileage was approximately 90,000.
F150 errors shifting, clunky shifts. Transmission rebuild at 105,000 mi, then again at 160,000 mi, then again at 163,000 miles. And total replacement at 163,300 mi.
The contact owns a 2018 Ford F-150. The contact stated that upon returning to the residence in another vehicle, the contact became aware that the vehicle was missing. The contact's son soon became aware that the vehicle was in the woods by the residence. Upon locating the vehicle, the contact noticed that the doors were locked and that the vehicle was still in park(P). The contact stated that the vehicle had shifted out of gear and had rolled backwards into the wooded area. The contact called the dealer and was informed that there were no recalls on the VIN. The contact was then referred to the manufacturer for assistance. The manufacturer was notified of the failure, and an appointment was scheduled to have the vehicle diagnosed by a dealer. The vehicle was towed to the dealer, and after a diagnostic was performed, the dealer discovered no defects with the vehicle. The vehicle was not repaired. The failure mileage was unknown.
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 federal safety agency 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.
The contact owns a 2018 Ford F-150. The contact stated that while driving approximately 30-40 MPH, the vehicle started jerking and shifting abnormally. There were no warning lights illuminated. The vehicle was taken to the local dealer, where it was determined that the failure was related to DTC: P076F/10R80, and the dealer informed the contact that the transmission needed to be replaced. The vehicle was not repaired. The manufacturer was contacted and confirmed there was no recall coverage for the issue. The approximate failure mileage was 102,000.
Engine is ticking and whistling. Drive train issues cam phasers was told beginning of the problem
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
On December 24, 2025 at around 2:00 pm While driving my 2018 Ford F-150 from Hidalgo, Texas to Ciudad Victoria, Tamaulipas, Mexico, a distance of approximately 220 miles, my vehicle experienced a sudden and dangerous transmission failure that placed myself, my family, and other motorists at significant risk. For the first approximately 130 miles, the vehicle operated normally with no warning signs. While traveling on a two-lane highway, I attempted to pass an 18-wheeler. During the passing maneuver, the transmission began harsh and jerky shifting, slipping, and delayed gear engagement, followed by an immediate and significant loss of power and acceleration. As soon as I completed the pass, the vehicle failed to accelerate properly and lost power, leaving me exposed in a dangerous situation with limited ability to increase speed. Because the road only had one lane in each direction, this created a high-risk scenario involving oncoming traffic. Within seconds, the 18-wheeler I had just passed rapidly approached from behind, forcing the driver to brake suddenly to avoid a collision. This put the truck driver, surrounding motorists, and my family at serious risk of a major accident. The failure occurred without warning and during a critical maneuver where reliable acceleration was necessary. The sudden loss of power made it impossible to respond safely, demonstrating a serious safety concern. At the time of the incident, the vehicle had approximately 72,000 miles, is well maintained, garage-kept, and has never been used for towing, heavy-duty work, or commercial purposes. Given the mileage and normal use, this type of transmission failure is unexpected and unsafe.
Truck has a lag then hard catch going from 7th to 8th gear and sometimes skips gears causing burnt transmission fluid and lower rear seals along with water pump seals all seals and gaskets are bad being ford used plastic gaskets that year and ford recommends changing to more current seals and gaskets but don't want to cover costs , my truck is sitting in a shop with 4,900.00 in repairs do to ford parts for that year faulty
Driving the vehicle when it tries to reach the 7th gear it loses power then drops to 1st gear and won’t pass 6th gear the check engine light came on and the maintenance light. Took the vehicle into the dealer to learn that the transmission is bad and I need a new one. Solenoid stuck position A. P0752
Bad transmission shifting at 80k miles. Apearently is a known problems. There has been a few times it shifted so hard that my neck hurts the rest of the day also take a minute to accelerate sometimes leaving in in front of oncoming traffic. No codes or anything, I’ve been told that it’s normal
Ford F150 10 speed transmission failure. Trying to cross intersection and transmission failed. I avoided an accident. Transmission had to be replaced at dealership. No warning lights or messages. Vehicle worked perfect until time of failure.
My 2018 f150 has a 10r80 transmission. I was driving through heavy traffic on US Route 93 southbound, moving at about 60MPH when the transmission suddenly lost all power. Because there was no left-side shoulder (I was in the left lane), I needed to throw on my hazard lights and make my way to the right shoulder across 4-lanes of traffic. Multiple near collisions as I had no propulsion to do this.
The contact owns a 2018 Ford F-150. The contact stated that while driving at an undisclosed speed, the vehicle lost motive power. The transmission warning light illuminated, and the message to "See Owner’s Manual" was displayed. The contact coasted the vehicle to the dealer, who determined that the transmission had failed. The transmission was replaced. The manufacturer was made aware of the failure. The failure mileage was approximately 83,000.
Previous issues with the 10r80 transmission with is holding onto 4th gear too long then dropping hard into 6th gear. Vehicle also slams into reverse from park or driv when cold. Reported to dealership at 20k miles, but they only did a computer reset before. This was before the CDF Drum issue TSB. Ford now refuses to acknowledge the issue and inspect it post warranty despite a history of the issues being symptomatic with a failing transmission.
The contact owns a 2018 Ford F-150. The contact stated that the vehicle would shift roughly and would hesitate before accelerating. The failure would occur at various speeds. There were no warning lights. The contact stated that the failure occurred while driving at 40 MPH, and the vehicle stalled. The contact had the vehicle towed to the dealer, who diagnosed that the transmission had failed. A mechanic affiliated with their warranty coverage also inspected the vehicle and determined that the Clutch/Direct/Forward (CDF) drum had failed. The transmission and the CDF had to be replaced. The vehicle was being repaired. The manufacturer was informed of the failure and opened a case. The failure mileage was 84,000.
Noisy engine when starting up, told by dealership this is known problem that Ford took care of until 2023. I was told needs to be fixed for catastrophic engine failure could occur. The repair is about $5000. This is my [XXX] sons truck he bought in August, and I am concerned that it is not safe to drive. A truck should last more than 100000 miles. It also has a known transmission problem that could also be a safety concern. I have not had that properly diagnosed but was told by dealership that it is a common problem. That repair is estimated around $3500. I am fairly certain Ford has lost a customer. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
The 10R80 automatic transmission exhibits harsh/delayed shifts, gear-slipping, and occasional unintended downshifts, especially at highway speeds. More specifically, gears 3 and 5 exhibit hard shifts at lower speeds in heavy traffic, such as stop-and-go city driving. The 8th gear specifically will have issues at higher speeds on the highway when you apply more gas, and the vehicle will drop out of 10th gear and have a very hard shift into the 8th gear, almost like the transmission is about to come apart at dangerous speeds. This appears to be a well-known issue that Ford has issued a TSB 21-2357 back in October of 2021. The specific problem has been confirmed with a dealer and ASE-certified mechanics from the dealership documenting the gear issues, as well as the CDF drum that is a known culprit in the earlier versions of the 2017-2020 F150, based on the poorly designed bushing inside of this drum that slides out of position, resulting in the pressure loss and slippage of gears. This has been confirmed by the dealership, as well as multiple issues documented on the 10R series transmissions. No warning lights or indicators other than The specific problem has been confirmed with a dealer and ASE certified mechanics from the dealership documenting the gears issues as well as the CDF drum that is a known culprit in the earlier versions of the 2017-2020 F150based on the poorly designed bushing inside of this drum that slides out of position, that results in the pressure lose and slippage of gears. This has been confirmed by the dealership as well as multiple issue documented on the 10R series transmissions. No warning lights or indicators other than how it drives and understanding the hard shifts are not supposed to happen in an automatic vehicle. The issue first started about earlier this year, and Ford told me it was an issue, but we can’t get to it for another 8 months. This is unsatisfactory and a huge concern for people and safety of others on the highways.
The 10 speed transmission suddenly jerks and briefly loses power at approximately 30mph and at or about at 5th gear. This happens during acceleration and deceleration This can lead to a dangerous situation where I could be hit from behind with sudden loss of power or not being able to get out of the way of an oncoming vehicle.
The contact owns a 2018 Ford F-150. The contact stated that while driving at various speeds, the vehicle jerked abnormally while accelerating. The failure occurred while the transmission was changing gears. The contact stated that the failure was most noticeable while pulling out of the driveway after the initial start-up. The vehicle was previously included in a recall related to the transmission, and the vehicle was repaired. The contact stated that the failure started after the recall repair was performed. The vehicle was returned to the dealer to be diagnosed, and the contact was informed that there were metal shavings found in the transmission fluid and that the transmission needed to be replaced. The vehicle was not yet repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 38,000.
Several times in the last few years when taking off from a stop about 4 seconds into travel the transmission disengages and the engine races. If I was expecting to get though an intersection while traffic was coming into my path of travel I would be in their way and possibly struck. It happened again today. Thankfully I had full right of way and not in anyones path of travel. I had to let the engine wind down, shift to nuetral and back to drive to get going again. I was in the middle of a left hand turn and behind other vehicles that were all traveling about about 5 mph.
Transmition Issues: Hard bumping going into gears, loss of power to move the truck, loss of power can happen anytime the transmition seems to shift into neutral causing a dangerous issue when trying to pull out to moving traffic. Stopping at intersections and then the truck wont go forward until there is a hard bump that feels like your getting rear ended. When diving at speeds above 45 the trans is constantly looking for gears. The truck only has 103000 miles on it. incident occurs 3 out of 5 times I drive the truck.
My 2018 Ford F-150 3.5L EcoBoost experienced cam phaser rattle/failure at 72,000 miles. The vehicle never received the 21B10 PCM reflash, and Ford Customer Care has denied any goodwill assistance. The cam phaser noise is a known widespread defect covered under Customer Satisfaction Program 21N03. I had the repair done out-of-pocket at a Ford Dealership because I was fearful that catastrophic engine damage would occur if left un-fixed, leaving me stuck in the roadway. I Request that this be logged for investigation and future regulatory review.
