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.

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.

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)

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.

Problems started when towing, going down a hill, the truck down shifted as it should. Once the road leveled out, the truck would not upshift until you came almost to a complete stop and started over. Took it to the dealership and was told it needed new software. Paid for software and truck had a shutter after that while going up hills without towing. Took it back and dealer did not follow TSB, but instead put a torque converter in. Picked up truck and less than 20 while driving on the interestate at 70mph, the truck downshifted so hard it chirped the rear tires. Took it back to dealership and transmission was replaced. Picked truck up and drove it for a few hundred miles and started leaking transmission fluid out the vent (accourding to the dealership) Dealership is stating its my fault due to towing a small trailer with around 4k pounds total weights. On interesate at 60MPH, in tow mode, the trunk was running at 1700 RPM and all temp guages normal so no stress at all on the truck. Truck is rated at 13k plus towing. Dealer also stated that hauling horse feed also overheated transmission. The new transmission "clunks" when going from park to reverse. The turck still surges. Some days its fine, other days not so much. In my opinion, poor quality parts caused the failure of the first transmission. Current problems, in my opinion the problems are software. The engine at speed is barely above an idle and not optimized for the engine power or torque curve. The silliness of skipping gears is also part of the problem.

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.-??

- Palmdale, CA, USA

Transmission is being replaced for a 2nd time due to erratic downshifting at highway speeds. Going from 10th to 1st to 5th and back to 10th gear. Then loss of power.

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.

Driving at highway speeds and my truck began to shake violently and very loud banging sound. Slowed down to pull over on the highway. Found driveshaft broken in half with gas dumping out of the fuel tank. Broken driveshaft damaged heat shield for gas tank, punctured gas tank and dented/broke clips on exhaust. Very lucky back driveshaft didn-??t hit pot hole and leaking gas didn-??t start a fire. Stranded on side of road for hours. Sent my vin to the dealership and they said my was not under the recall #21S56 even tho it was built after known driveshaft issue and clearly the insulator caused the issue.
