Truck would downshift for no reason. This happened on multiple occasions. The vehicle was taken to the Ford garage and was told there was a sensor that needed to be replaced. After servicing the vehicle the transmission was worse was told that it needs to self adjust. Now waiting to see if there are any further issues. Apparently this is a known issue with these vehicles but mine was not one that was recalled.

While driving on the highway the Transmission on the 2020 F-150 began to switch back and forth from 7th gear to 8th gear and then jump to 10th gear and all of a sudden drop to 1st gear causing a skid to happen. A orange colored wrench came on the dashboard after the skid took place. I brought the truck to the dealership where I bought it and and requested a new transmission be installed. This being the second time the trucks transmission is being worked on which only has 15K miles. The dealership is currently refusing to install a new transmission and want to only fix what they feel is required.

I am experiencing sudden deceleration when the gear suddenly shifted from higher gear 7, 8, 9 to gear 1 for only a few seconds then shifted back to gear 7, 8, or 9 again. This could happen at lower speed like 30s or 40s mph, or also happened at higher speed like 70s. It happens randomly. There are also other typical transmission issues like hard shift, will not shift into gear etc.. but the random gear shifting from high gear to low gear is the most serious issues. The local Ford dealership has attempted to repair the problem by check the valve body and update the software, but this did not fix the issues. The error message was appeared on the dashboard screen.

The transmission started to jerk when shifting. It got to where it wouldn’t shift past 6th gear. I didn’t get any kind of warning lights. I took it to the dealer and they said the transmission needs to be rebuilt. The rebuild is going to take 4 to 6 weeks and in that timeframe I don’t have a vehicle.

On [XXX] while attempting to take a trip to WV we were traveling on [XXX] nearing Waynesboro, VA. While driving up the mountain on [XXX] near the Rockfish Gap overlook I noticed our F-150 seemed to mis-shift or slip. As we’d experienced issues during a previous trip that required the transmission to be serviced under warranty I switched the display to the transmission temperature near 245 degrees. I attempted to put the truck in eco mode and slowed below the speed limit to the top of the mountain. While going down the west side of the mountain I left the truck in cruise. Past the [XXX] exit I noticed smoke which began to increase. I then checked the temperature again which reported 267 degrees. The wrench warning light came on indicating reduced power. I also received the notification on the Fordpass Application. The truck quickly slowed down and would not accelerate forcing me to hastily move to the shoulder in heavy traffic. We pulled over at stopped right in front of mile marker [XXX]. A large amount of transmission fluid observed pouring out from above the bell housing onto the exhaust. It appeared and smelled like it was possible to catch on fire so I did not park over grass, remaining on the concrete shoulder. After a dealer tech simply reset the computer and stated it was fine we drove the truck home, but did not feel safe or sure that it would make the trip. The transmission temperature remained below 220 the trip home but did have delayed shifts. The next day I had three incidents after exiting the interstate of a failure to find a gear for a moment as I attempted to take a turn. Our dealer that we trust has already completed two TSB actions related to the transmission. The other dealer cleared the computer and did nothing to repair the issue. They also attempted to charge me for a diagnostic fee, even though it’s under warranty and clearly had issues to include gear ratios being wrong and ECM/PCM and BCM communication failures.

The transmission slips when giving it gas. I lose power when I excelerate Sometimes. Sometimes the truck excelerates when I'm not giving It throttle. Transmission jumps all over. The transmission seems to be very rough shifting back and forth

When the truck is trying to change gears, there would be a long hesitation before it can move up to the next gear while accelerating. The truck would sometimes lose power and speed while trying to find the gear. It would sometimes jump from gear 1 all the way gear 10 and then randomly bounce between the other gears before actually settling. At the moment it does find the right gear, the truck would launch forward violently. I took it to a ford dealership to be diagnosed, where I was told a new transmission is needed. I reached out to the manufacture regarding the issue and was told that there is no assistance for the issue. The quoted cost for the new transmission is $8400.00. I did some research and found that a lot of recent model Ford trucks a having the same problem with the transmission. Most report I read encountered the problem before 100000 miles. The truck is currently at the Ford dealer waiting to repaired. I find this is unfair to consumers to deal with an issue of this expense on what I consider to be a new truck.

My 2020 F150 transmission is having serious issues related to accelerating and decelerating, and rough shifting (causing jerking forward and backwards) which are now a major safety concern. The transmission gets stuck in gear, sometimes shifts from 4th to 1st gear, gets stuck in 7th gear, or will not shift out of 1st gear. Earlier this week with my wife driving the vehicle (with my children in it), it would not accelerate due to this issue and getting on the highway, she had to quickly pull over narrowly being missed by a cargo truck since the vehicle would not accelerate. I took over driving the vehicle, and I've observed the gear changing issues noted above and also had to pull off the road to avoid stalling the vehicle in the middle of a busy road. I've addressed these issues with Ford corporate, and their official position is that I have to have the issues diagnosed with a Ford dealer, which is telling me diagnosis is 8-12 weeks out. I don't know what else to do, but I am very concerned about the safety issues this is presenting

-10R80 Transmission began malfunctioning at 86,000 miles. Per Ford dealer, the shift strategy was cleared which did not resolve issue. Internal transmission failure was suspected and transmission was replaced. -From a complete stop, the truck would not want to shift from 1st to 2nd gear unless driver let off the gas causing unnecessary risk. From there, truck would shift extremely hard while under acceleration. Additionally, there were instances where truck would not downshift while slowing down to a stoplight. Truck remained in 7th gear at the green light and could only be moved by switching truck to manual shift. -Issue was verified by an independent shop along with a local Ford dealer. -Unsure if the component has been inspected by manufacturer as it was replaced by them. -No engine lights, codes, or other symptoms.

Started having rough shifting from 1st to second at 99k miles. Quickly progressed to 3-4-5 gears shifts. Finally couldn’t drive the truck in auto because it was having trouble finding/shifting into gears up to 60mph. I had two instances when driving in 8th gear around 55mph and the transmission randomly shifted to second. Caused the vehicle to lurch violently and over-rev the engine. I had several other instances when traveling above 60mph in 10th gear and the gear indicator flashed between 10th and first gear. Thankfully it didn’t actually downshift. Tried taking it to a dealership near me but they were backed up two months on transmission work. I wound up taking it to a local shop and they rebuilt the transmission. They found the typical c-d-f drum bushing failure that is common in the 10r80 transmissions.
