My truck started to throw codes p0240 and p0430 when my truck hit 81000 miles. I am now at 141000 miles. I have since replaced both of my catalytic converters, all 4 of my O2 sensors and I still have the same p0240 and p0430 codes. I also took my truck into ford on Feb 26, 2025 for the recall on my PCM reprogramming. They claimed to have redone the programming but ever since they did that, I now have shifting problems, surging, clanking, hard shifting, random and sporadic shifting with no end in sight. This should be addressed by Ford TSB 24-2101 but again, they did nothing and claim there is nothing wrong with my truck. I have had a fluid replacement and filter replacement with no issues noted, no metal parts, no burnt smell or burnt fluid. Today I came across Ford TSB 24-2184 where they acknowledge that there is an issue with the calibration and controls sensitivity and that replacement of catalytic converters may be necessary. Ford never did any of this. The recall on my truck, which was reprogramming of my PCM also leads to dirty and fouling of the catalytic converter. I have spent over $3000 so far to fix Fords mistakes and not only in nothing fixed, I still have the exact same issues. When i take it to Ford, all the do is clear the codes and then the codes come back on before I get home. So Ford is aware of the issues, knows about the issue and yet will do nothing to fix it.

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.

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.

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 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.

My 2020 Ford F-150 EcoBoost with the 10-speed automatic transmission (10R80) is experiencing the same transmission shifting issue covered under NHTSA Recall 22V188 (Ford Recall 22S71). My truck intermittently shifts erratically, including hard downshifts, delayed upshifts, and occasionally feels like it jumps to a lower gear unexpectedly. This creates a noticeable jolt and could potentially cause loss of vehicle control in traffic or inclement weather. I contacted Ford and was told my VIN is not included in the recall, even though my symptoms match those described. There is also a known TSB (22-2225) for this issue, but the dealer won’t cover it under warranty since no recall appears for my truck. I am requesting that the recall and/or investigation be expanded to include more affected VINs from this model year, as this is clearly not an isolated issue.

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.

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 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)

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

2020 Ford F-150 with 62,400 miles and a 10 speed automatic transmission. Transmission has failed! The truck is at Bill Brown Service in Livonia, Michigan. At 62,200, the transmission was not engaging and disengaging when ever it wanted to. This has happened several times and resulting in inability to drive and control the vehicle. This had happened previously over the past few weeks but only in a parking lot or the driveway. Now it is happening every time the vehicle is driven. Ford said the repair would be $3,500 to $4,500. They have offered me a discount and my portion would be $1,600. This truck has never towed a trailer, never had a hitch in the receiver and been offroad or barely on a gravel road. All maintenance has been done to this vehicle and was due for transmission fluid replacement. Ford should bare all of the cost for the transmission repairs and should recall this transmission before someone gets injured. I have the same transmission in a Ford Explorer that has had to be worked on two or three times now. Thank you for your consideration in this matter [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Ford F150 Mileage when 10R80 Transmission Failed: 66,195 New 10R80 Transmission Replacement of Original Factory 10R80 Transmission installed on September 20, 2024 Original 10R80 Transmission Failure Date: [XXX] Brand New 10R80 Transmission Installed: September 20, 2024 2nd Incident Malfunction of New Replacement 10R80 Transmission: [XXX] 3rd Incident Malfunction of New Replacement 10R80 Transmission: [XXX] My 2020 Ford F150 transmission failed on [XXX], on [XXX]. The truck lost power and the transmission was shifting erratically. Upshifting and downshifting and the engine revved up. A Warning Light came on as a transmission failure. I was driving in a construction zone without shoulders, so the experience was terrifying for my Wife and I when the transmission failed. There was an emergency turn off and I pulled my truck off the highway and looked underneath and saw the entire underside of the truck covered with transmission fluid. When the 10R80 transmission failed, the mileage on my 2020 Ford F150 was 66,195 miles. The powertrain warranty on the vehicle is up to 60,000 miles. Ford Motor Company and the Ford Dealer offered no financial help to replace the factory original failed 10R80 transmission. On September 20, 2024, I paid Front Royal Ford $8,756.13 for a new transmission and installation. My assessment is that the transmission failed when driving up a mountain for several miles at a steep grade. On [XXX], the new transmission installed started acting very erratically and the transmission disconnected from the engine and a total loss of power occurred. The transmission randomly started downshifting and upshifting. Transmission fluid leaked from the new transmission. The 2020 Ford F150 was put in the Service Department of Front Royal Ford, and they could not replicate the problem and told me to pick up the vehicle.

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.”
