general problems of the 2020 Ford F-150 - part 2

Transmission shifts hard looses power. I reported it to Ford before my warrenty ran out. They said it was fine and just needed an update. It did not fix it took it and got second opinion and the transmission was bad and needed to be replaced. I had to pay out of pocket because they did not take care of the issue while it was under warrenty. Now im out 7000 because of a faulty transmission and Fords lack of addressing the issue.

10 speed transmission, started slipping. And then slamming into gear while it would down shift. We have had 4 rebuilt transmissions put in with Ford. And now the truck just went into the shop again for the same issues. This last time before going into the dealership, felt like the transmission was just going to drop out. It was hard. Do not feel safe in this truck any more. It is not reliable. No warning lights at all.

The Ford 10 speed transmission has continued to give me issues. Delayed shifting, harsh engagements, and overheating are the symptoms. I have been to the dealer several times for the issue. They programmed the transmission, reset values, then replaced the valve body. After valve body replacement, the service manager at the dealership told me that it shifts fairly well compared to other f150s and there’s nothing more they can do. There have been several instances where I have to pull over in traffic due to overheating. The lack of predictability in the shift also makes for unsafe situations.

Component/system failure: the 10-speed automatic transmission failed prematurely at only 75,000 miles. The transmission is still in the vehicle and available for inspection upon request. The symptoms include harsh shifting between gears, particularly into lower gears, followed by significant lag and then abrupt jumping/engagement. This is consistent with numerous other complaints filed regarding the 10-speed transmission in this model year. Safety risk: the unpredictable transmission behavior created dangerous driving conditions. The harsh shifting and lag followed by sudden acceleration made it impossible to safely merge into traffic, navigate intersections, or maintain consistent speed on highways. The erratic gear engagement put myself, my passengers, and other drivers at risk as the vehicle's response became completely unreliable. The truck is currently unsafe to drive. Professional confirmation: yes, the problem has been confirmed by aamco transmission on sept 17, 2025. They diagnosed it as transmission failure requiring complete replacement. Manufacturer/other inspection: no inspection by Ford has occurred to date. Warning indicators: no warning lights, check engine lights, or dashboard messages appeared prior to or during the failure. The only symptoms were the physical driving symptoms described above—harsh shifting, significant lag, and abrupt gear engagement—which began approximately gradually over the past month and progressively worsened until the vehicle became unsafe to operate.

The transmission has harsh, jerky, clunking shifts. It also has delayed engagement and complete power loss. There is also problems with downshifting from 7th gear to first gear when coming to a complete stop. Vehicle seams to be in neutral then finally shifts to 1st gear before vehicle finally moves.

* what component or system failed or malfunctioned, and is it available for inspection upon request? transmission/powertrain; currently available for inspection at time of submission * how was your safety or the safety of others put at risk? while stopped at stop sign/stop light, the vehicle would have long hesitation before advancing forward. I would initiate hazard lights to prevent driver behind me from crashing into the back of my vehicle. The vehicle would shift harshly and untimely as well as randomly downshift from 10th gear to 1st gear (x2 on 24aug2025). I would have to pull vehicle off the road and when attempting to resume driving the vehicle would not move. The rpm’s would rev, however the vehicle would not move. I would turn off the vehicle and then restart it and the vehicle would move forward, resuming with harsh shifting. Loss of power, delayed and harsh shifting pose a safety hazard while the vehicle is in operation. * has the problem been reproduced or confirmed by a dealer or independent service center? yes; by independent service center * has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? no * were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? first check engine light illuminated on August 16, 2025. (please note the check engine light disappears once the vehicle is turned off and then restarted). I took the vehicle to autozone on 25aug2025. The tech placed the code reader on the vehicle. 2 codes, p0734-00 and p07f7-00, ‘gear 4 incorrect ratio’ and ‘gear 10 incorrect ratio’ respectively were displayed. Vehicle taken to independent service center on 25aug2025 who also placed code reader on vehicle. I am not in possession of that information at time of writing. Monthly ‘my vehicle report’ has been clear with no issues whatsoever noted until report dated 25aug2025 (attached).

Transmission has on several occasions lurched when starting the vehicle. During driving, the transmission shifts hard and sometimes jumps in and out of gear as if it cant decide which gear to engage. This often happens at low speeds after first start, and between 5th and 6th gear.

The first transmission I had in my truck I had. Harsh shifting, slipping gears, delayed engagement, transmission overheating, loss of power and transmission stuck in higher gear while stopped. They replaced the transmission (at my cost ) now I have over heating issues. There should be a mandatory recall on this transmission, give me my money back and fix the issues for free.

Transmission has been skipping gears, hard shifting, getting stuck in gears. While traveling in the truck going up an on ramp and then trying to merge into traffic, the transmission got stuck in 7th gear. Pressing the accelerator would not move the vehicle and I was left without the ability to move out of traffic. Vehicles were having to put on their brakes, swerve and go around me. Prior to this time I was having some slight shifting irregularities between gears 2-3 and 7-8. I notified the dealership of issues and they said I would have to drop the vehicle off and it would take 7-10 days before they could even look at it. The vehicle was purchased in December 2020 and currently has just under 75,000 miles. I was told that it was out of warranty. For the first 4 years of ownership the vehicle has always been serviced at a Ford dealership. I was never notified of any issues with the transmission. However they did notify me that a windshield wiper arm was recalled and that was changed. Early in the ownership of the truck, I experienced the vehicle moving backwards when on an incline and taking my foot off of the brake, before accelerating. Also, experienced clanking and jarring when accelerating and then having to take foot off of the accelerator. In 2023, when having the vehicle serviced for oil change, I asked the service technician about these issues and was told that there was nothing wrong and that it was just typical for that type of transmission.

The transmission failed. While driving, it shifts extremely hard and will suddenly downshift without warning. Autonation Ford of north canton, ohio, inspected the vehicle on August 13, 2025, and reported that the cdf drum clutches were likely worn. The truck is available for inspection upon request. The sudden downshifts cause the truck to jerk violently and lose speed abruptly. On multiple occasions, this has nearly caused me to lose control and creates a high risk of being rear-ended by other drivers who are not expecting the sudden slowdown. Yes. Autonation Ford of north canton, ohio, confirmed the issue on August 13, 2025. Yes. Autonation Ford of north canton inspected the transmission and stated it was likely due to worn cdf drum clutches. There were no warning lamps or messages. The symptoms began before August 2025 when the transmission started slipping, shifting hard, and then downshifting unexpectedly. The issue occurred just one month after the warranty expired. The dealer quoted me approximately $7,000 to repair it. I have read that Ford has replaced the old pressed bushings in this part with welded ones to prevent this failure, which suggests this may be a known defect in the original design.

December of 2020, I purchased 3 - 2020 Ford f150's with 5. 0l engines and 10speed 10r80 transmissions for 2 of my companies as personal drivers (non-commercial use). *vehicle 1 - at 82,000 miles - was experiencing missed shifts, and harsh engagement. Within a couple of weeks of this happening, unfortunately the vehicle was totaled in an accident unrelated to shifting. *vehicle 2 - began to experience the same problems, this vehicle would miss a shift and fall completely "out of gear" leaving no power or throttle response (roughly 78,000 miles) and had been service according to Ford specification and mileage with motorcraft factory filter, gasket, and Ford ulv fluid. Unfortunately this was the only vehicle I purchased an extended warranty for due to long highway trips out of town where a breakdown would be difficult to deal with out of town. Determined as "transmission failure" and replaced at billy howell Ford in cumming GA. (via extended warranty) *vehicle 3 - VIN number in question - at 74,000 miles vehicle is now missing shifts, jumps out of gear. 2 dangerous scenarios this week. Crossing oncomming traffic to turn onto road - 1-2 or 1-3 shift missed and complete loss of power/movement barely avoiding being hit by oncoming cars. Second occurrence, slowing to a red light on wet road. Coasting/braking as transmission began downshifting from 10th gear,. . When it got to 7/6 it downshifted to gear 4 sliding/screeching the rear tires as the rear end slid/drifted sideways causing me to panic stop with brake pedal fully depressed to avoid free sliding or losing control of the vehicle. -100% available for inspection Ford should absolutely recall all of the early 10r80 equipped vehicles. It's dangerous!! vehicle has been checked/duplicated and verified by ase certified technician, local dealer admitted to problems, there are no mil's, and no fault codes stored computer. Dealer wants almost $9000 to replace transmission. Ford do better! -- this is dangerous.

The contact owns a 2020 Ford F-150. The contact stated while driving 40 mph, the contact heard a raddling noise coming from an unknown part in the vehicle. An independent mechanic was contacted. The vehicle was taken to an independent mechanic where it was diagnosed the transmission needed to be replaced. The manufacturer was notified on the failure and offered no assistance. The approximate failure mileage was 118,923.

The rear differential exploded while driving without warning. Immediate lose of power while traveling 70mph, the explosion blew some hot parts of the differential off the road and started a brush fire.

Transmission downshifted on the interstate and overheated. Wouldn’t go back in to gear. Was in the passing lane and ended in an accident.

This truck has the notorious 10 speed transmission. It has severely abrupt shifts, thuds, clunks. Sudden loss of power or surge of power when transmission shifts. Nhtsa is my only hope of getting the transmission repaired and safe. Not just my truck my sons 2021 had the same issue. Bad cdf drums. Ford revised the sort for 2023 and eliminated it but everyone from 2017-2021 are stuck with an erratic, dangerous transmission that needs recalled.

I’ve already had 10r80 10 speed transmission replaced once at 53,000 miles. Now I’m at 65,000 miles and I’m having issues again. Twice this past week, my truck has shifted from 6th gear down to 1st gear while driving for no reason. I’m getting rough shifts again and a lot of clunking and jerking.

The contact owns a 2020 Ford F-150. The contact stated that on multiple occasions while driving at various speeds, the vehicle would accelerate upon depression of the brake pedal. The contact stated that the wrench(transmission) warning symbol had appeared on the instrument panel and a "power train malfunction reduced power" notification would appear on the contact's Ford mobile app. Recently, the contact stated that while driving at 60 mph, the vehicle downshifted upon depression of the accelerator pedal. The contact stated that the transmission began to rev as the rpm's shifted back and forth from a low gear to a high gear. The manufacturer was notified of the failure and the contact was informed that manufacturer could not create recalls; they referred the contact to the NHTSA hotline to file a complaint. The vehicle was not repaired. The failure mileage was approximately 100,000.

Experience harsh engagement with transmission both upshift and downshift. Some downshifts at so harsh, feels like rear wheels are trying to “lock up”. Ford dealer performed recall which did not correct the issues. Ford dealer recommended full transmission replacement. Seems this is a known issue and Ford has admitted fault by issuing a recall in an effort to “fix” the problems with the 10 speed transmission.

The contact owns a 2020 Ford F-150. The contact stated while driving at an undisclosed speed, the contact heard an abnormally loud pop. The contact drove the vehicle to the shoulder of the road. In addition, the contact stated that the transmission was slipping. The automatic transmission failure warning light was illuminated. The contact turned off the vehicle. The vehicle was restarted and driven to the residence. The vehicle was then towed to the dealer where it was diagnosed with transmission failure. The contact was informed that the transmission needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 126,000.

Ford 10r80 transmission slips or revs for long period of time before banging into gear when accelerating. When accelerating and merging onto the highway I am unable to merge and accelerate to highway speed without the risk of being rear ended by oncoming vehicles already at highway speed. The vehicle has been inspected and confirmed that the transmission needs to be replaced. No other lights and absolutely not warnings at any time before problem started. As per TSB 23-2250 and several earlier TSB on this transmission, having a known defect, Ford should escalate this to a recall and compensate owners for the expensive repair when the vehicle should have plenty of more life in it.

I have a 2020 f150 king ranch with 64k miles on it. It has always shifted harshly, but I had thought that was just the issue with the design of the 10-speed transmission. Right after 60k miles, the transmission would stay stuck in 1st and rev the rpms high and then jump to 4th. There were other times where the transmission would harshly jump up or down gears. I took it into the local Ford dealership to be reviewed. Of course, this is another case of a faulty 10r80 transmission. I had to get the entire transmission replaced. An almost $10k repair and Ford motor CO only covered $3800 of it. This is unacceptable, dangerous, and quite frankly irresponsible of Ford. I called the Ford customer service three times, each of which, they referred me back to the local dealer (who referred me back to the Ford motor CO case). Some quick background. I'm a very loyal Ford customer. I've owned 3 f150s, an expedition, and a Ford fusion. I get all of my services done at the local Ford dealership. I've never had a transmission go out and especially on such a new truck. ** I rarely tow, so this hasn't been a truck that has been towing a lot of weight (I've towed 4 times with a trailer < 4000 lbs). Customers shouldn't have to pay over $5k for repairs on a truck less than 5 years old that cost over $70k (and 4k miles beyond the powertrain warranty). That's ridiculous. Ford should step up and do the right thing and recall these transmissions for the customers experiencing problems. I now know of 6 personal people (in a small town) that has the same issue and the dealership is full of trucks with the same transmission problems.

There is a flaw in the design of the 2020 f150 and specifically the 5. 0l v8 engine. I have kept up to date on all maintenance, no visible oil spils and engine is consuming/burning significant amounts of oil. I've been told by numerous dealerships/mechanics that there is nothing that they can do and to try and join all of the class action lawsuits. I spent 50k on a vehicle that isn't even making it thru the life of the loan. . . . . Why do I have to do a class action. This should be consumer protection.

I have a 2020 f150 with just over 58,000 miles. I work from home, and do not tow. While driving up a four lane highway to boone, nc, my vehicle's transmission appeared to get 'confused' and threw a fault. I took my truck into a dealership to have the issue resolved, and was told that I needed an entirely new transmission because the cdf drum was failing to the tune of almost $10,000. I have brought the issue of hard shifting, and the transmission slipping up to crossroads Ford of kernersville previously, but they have refused to look at it because of it was not throwing a code. I called Ford, and they stated that the vehicle would have to encounter a total failure with the transmission before they would look at it. They referred to me driving on a four lane highway to a higher elevation as extreme driving conditions. [xxx] was built in 1930, which is they road they referred to as 'extreme'. From there, the manufacturer told me that they would cover 40% of the repair. To me, this indicates a known issue with the vehicle's transmission and cdf drum and requires a recall to be issued by Ford motor company. This is a known issue amongst many f150 owners, and a simple google search will show that many drivers have experienced this. This has been addressed by TSB 22-2428, but Ford should be responsible for manufacturing a defective product. I do not tow, do off-road activities, and I work from home. There is no scenario where my actions should cause this type of failure. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

While driving on the interstate doing around 70 mph I I stanton drive up a fairly steep hill on the road . About half way up the truck down shifted from 10th gear too what it said was 7th. The gear did not engage and the truck revved up like it was in neutral. I pulled over immediately. Checked under the truck and no leaks. Got back in and truck ran like normal. Went to the dealer and was told that is a common issue with this particular transmission. I also have noticed when driving and coasting too a stop when the truck downshifts there is sometimes a loud clunking sound. Ford needs to be help responsible for putting trash transmissions in these vehicles. Please advise them to issue a recall and repair or replace them.

The 10-speed transmission downshifted from 10th gear to 1st gear, and then back into 10th again. This sequence happened 3 times in a row, with the 3rd causing a service light to be displayed. This occurred while on the highway with cruise control set at 75mph. The truck is available for inspection upon request. This transmission malfunction caused an abrupt and rapid deceleration, as well as, a loud clunk and temporary lockup of the rear end. The deceleration and loss of power had the potential to cause an accident with cars around me, or a loss of control from the rear end. There are an overwhelming amount of reports of this same issue online, as well as, numerous at the dealership. My truck has been to the dealership and they are claiming it is due to overfilling of transmission fluid during my recent transmission rebuild.

The contact owns a 2020 Ford F-150. The contact stated that while driving with the cruise set at approximately 65-70 mph and passing in the left lane, the accelerator pedal was depressed and there was an abnormal clunking sound while downshifting. The contact pulled over and restarted the vehicle. The contact stated that the “wrench” symbol was displayed. The vehicle was taken to an independent mechanic who retrieved dtc: p07f7 - indicating a failure with the 10th gear in the transmission. The vehicle was taken to the local dealer where it was diagnosed and determined that the transmission needed to be replaced. The vehicle was repaired. The manufacturer was contacted and confirmed there was no warranty coverage on the vehicle. No assistance was provided. The failure mileage was approximately 65,000.

The contact owns a 2020 Ford F-150. The contact stated while driving 65 mph, the transmission failed to operate as designed, and the vehicle started losing motive power. The contact stated that the vehicle jerked and briefly hesitated while the transmission was unexpectedly downshifting to fourth gear, and then downshifted to first gear. The vehicle returned to normal functionality after the failure. There was no warning light illuminated. The vehicle was taken to the dealer, who diagnosed a failure with the transmission. The vehicle was not yet repaired. The manufacturer was notified of the failure, a case was filed, and the contact was referred to the NHTSA hotline for assistance. The failure mileage was approximately 120,000.

While driving down the road the transmission in the truck made a load noise and now the truck will no shift properly. Because of this I could have been hit from behind by another truck by the sudden shifing problems from the transmission. This truck has jumped in reverse before and has had transmission problems Ford has refused to adress. This is the second powertrain problem to happen in this vehicle going down the road.

At 63mph my transmission started shifting erratically between gears, jumping into 1st gear twice. The transmission is being repaired by Ford at my expense now. There were no warning lights or previous indications. The 10r80 transmission is dangerously flawed and should be recalled by Ford.

Acceleration without foot on gas pedal, erratic & harsh shifting, and slipping gears.

Transmission routinely drops from 4th to 2nd rapidly decreasing speed (~40 to 20 mph) with loud clink. Maybe one day it will lock up. Took it in for warranty: “it will progressively get worse until just outside of warranty, then we’ll replace the transmission. ”.

The contact owns a 2020 Ford F-150. The contact stated while driving at an undisclosed speed and attempting to accelerate, the vehicle jolted into gear, prompting the contact to return to the residence. After arriving at the residence and shifting the vehicle into park, upon releasing the brake pedal the vehicle briefly started to roll away. The contact also heard an abnormal humming sound coming from the engine compartment. No warning lights were illuminated. The vehicle was taken to the dealer, who diagnosed a failure with the transmission. The contact was informed that the transmission needed to be replaced. The manufacturer was notified of the failure, a case was opened, and the contact was referred to the NHTSA hotline for assistance. The failure mileage was 26,000.

Transmission stalled into first, wouldnt allow you to put vehicle into gear unless you turned vehicle off and back on. Ford service center verified concern in parking lot. Vehicle starts in fourth gear and lunges very rough. No dtc. Fluid level full but very dark with fine metal contamination present. Perform cdf test. Results fail. Cdf bushing has slipped completly blocking fluid ports. Also suspected hub basket has worn grooved from f clutch application causing fine metal in fluid. Overhaul needed for repair safety concerns: my truck stalled in an intersection which put me, my pregnant wife, and our [xxx] daughter at risk of being hit by another vehicle. After speaking to multiple services centers (both Ford and 3rd party), I was told by * of them that they've been replacing 10-speed Ford transmissions like crazy these past few months. My vehicle is currently at a certified Ford dealership pending repair. Currently contesting a denial in financial assistance considering the vehicle is within the 5 year powertrain warranty (the vehicle had an initial 5 year, 60,000 mile warranty and my truck is at 72,200 miles). No warning lamps or messages occurred until the moment the problem occurred. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Transmission engages and disengages periodically as I slow down or come to a stop. Shifts erratically while driving from 6 gear to 4th gear , and when accellerating it hesitates from 2nd to 3rd gear, then shifts hard to 4th gear where I have to press on the brake to stop it. My concern is when it down shifts hard while in traffic, almost got rear ended one time. Just not safe to drive, ive have this truck for less than 5 months now. Preowned with less than 100k miles, just doesnt make sense. .

Transmission shifting erratically between gears, sometimes shifts hard enough to jerk the truck. I have searched Ford owner databases and this is a common problem with the 10r80 transmissions.
