In April 2025, my 2018 Ford F150 5.0 XLT 4x4 truck began harsh shifting from 1st to 4th and 5th gears. Then as I drive it awhile it will suddenly downshift from 8th to 1st gear causing a pause in driving. I was almost rear-ended by a car behind me. I took my truck to Clement Ford in O'Fallon Mo where they recommended a software update and resetting of the adaptive drive learning program. This cost $427.81 and has not fixed the problem.

When speeding up and downshifting the transmission will shift up and down rapidly and repetitive. Example, when passing another vehicle. Seems to do it when the transmission has to downshift more than one gear. Starting happening after truck got recent pcm update. Doesn-??t happen when only downshifting one gear.

- Buda, TX, USA

Since I purchsed this truck it has been to the 3 Ford garages. At first I had a vibration in 3 rd gear and 7th. Finally after spending a lot of money a Ford service said it was the drive shaft. The vibration lessoned. For the past 6 months the transmission pauses between shifts making dangrous when your moving then the truck pauses for a couple of seconds. First you could grt hit from the rear. Second if your turing onto a lane and it pauses as someone is coming. Possible accident.

While driving i was coming to a stop approaching a traffic circle. I had to yield the car already in the circle as i was stopping the truck made a clunk and lunged forward while i was breaking forcing me to enter the circle before it was safe to do so. I almost collided with the approaching vehicle with a child in the car. Another instance the vehicle between shifting gears randomly lost power as if it shifted into neutral, then a loud clunk as it finally found the gear when it did the vehicle lunged forward. Another instance with the vehicle in park i started the engine, after the starter finished and the engine turned over there was a loud clunk and the vehicle lunged forward in park enough that the tires made a noise and could have hit a parked car in-front of me. The dealership said it is a known issues with the 10R80 transmission and will cost me $8,000 to $10,000 to repair. This transmission has always clunked and missed gears since i bought it new in 2018 and i have had it looked at multiple times, but the dealerships always said its -??normal-?? Ford knows this is an issues and has not issued a recall and it is very dangerous.

Transmission shifts erratically causing loss of power at highway speeds. Transmission issues have occurred since the first month of ownership. Truck lunging when in park, down shifting from 10th gear to 7th at highway speeds, etc. Early problems/concerns were mentioned to service advisors when the truck would be taken in for service but I was always told, that is just the way that the 10R80 works. As time progressed, shifting issues got worse. They significantly increased after the powertrain warranty expired. Currently the truck shifts erratically in low and high gears and frequently experiences a complete loss of power travelling on the interstate. My biggest concern is that this is a known issue by the Ford Motor Company that has not been properly addressed via recall. The CDF drum inside of the transmission has a known design flaw and has been revised to eliminate the issue. The web forums dedicated to the F150 and any other model of vehicle ford equipped with the 10R80 are littered with similar stories and concerns regarding the transmission. ultimately, with the total loss of power at highway speeds and the need to immediately vacate lanes of travel to allow the vehicle enough time to figure out what gear it needs to be in, or to shift appropriately to regain highway speeds poses an immediate threat to any vehicle equipped with the 10R80 transmission and the original, or any early design, CDF drum. I would also like to note that I entered this with the most recent occurrance of this issue. It has happened multiple times during the course of ownership both before and after the warranty expired. Unfortunately, all of the Ford service writers/techs/managers, claimed that it was normal operation of the transmission.

- Springfield, MO, USA

The 2018 F-150 has a huge oil consumption problem, constantly having to add oil after several hundred miles driving the truck, at a minimum a qt at a time. The F-150 10speed transmisson also has a hard shift and jerks while shifting gears, after it warms up it the harshness of the hard shift goes away but still has the hard shifts. There is no warning lights on the dash, and it can be reproduced. Have on several occasions with the hard shifting almost caused several accidents being rear ended due to the truck not shifting out of gears as it should. Along with several times on the interstate after having to stop for other accidents and the truck not getting back up up to speed as it should.

Was driving approximately 55 MPH on a busy highway when all of a sudden vehicle lost all power and check engine and service lights came on. I had to immediately try and merge to the side of the road which created a unsafe situation causing traffic to slow immediately behind me so that I could coast to the side of the road and into a parking lot. Engine still running, transmission issue. Felt like it was in neutral; however vehicle selector was in drive. Had vehicle towed to dealer and was told it is an internal transmission issue and that I need a new transmission. They want to charge 11K to replace with new one. Ford rebuilt this transmission at approximately 29k due to issues and 80k miles later having issues again. This transmission always shifted hard and would drop down in gear while traveling creating an unsafe situation. Ford knows about the issues with these transmissions in the 2018 year F150's and hasn't implemented any recalls, only TSB's that don't fix the issue. I am still getting quotes from other repair shops to replace the transmission.

- Warminster, PA, USA

The 10R80 transmission slipping in 1st gear, the engine will rev to 2000 rpm and without warning the transmission slams into gear causing the tires to spin. The loss of ability to engage into gear caused me to need to pull over to the side of the road on two separate times. This has happened when the transmission temperature is cooler. The failure occurs unexpectedly. I have brought the vehicle to a local transmission repair business.
