2020 Ford F150 83,000 miles Automatic Transmission 10R80 loses power driving while shifting at multiple different speeds. Causes vehicle transmission to disengage while driving on the freeway and over rev engine. Sometime vehicle will not engage from full stop or slow start. Causes extreme jerking when finally engaging transmission. Vehicle gave me whiplash upon engaging. Cannot rely on transmission operation in any traffic condition.
While driving on the highway the truck shut off. A message appeared (Auto StartStop Shift to P, Then Restart Engine) This is an ongoing issue. It has happened three times already while driving. After the error message appears I stop, the turn the truck back on and it works perfectly. The issue is that the truck turns of while going at any speed. I have already replaced the battery.
The transmission is currently at dealership having transmission replaced at only 54,000 miles. The truck started experiencing rough shift, sometimes taking a few seconds to actually go into gears 4-6. While on the highway, I had to use extra caution merging on or off the interstate because of the delay in changing gears. The dealership shop has told me the CDF drum is damaged internally and they are replacing it with a re-manufactured transmission.

My sons 2020 ford f150 felt like it was losing power. As I turned onto highway. The truck shifted from the first gear to second gear smoothly, asthe truck shifted from 2-3 , the truck reved and did not engage into 3rd gear. I let off the gas, thinking it will catch the next gear and continue to increase speed. But it did not, it again reved and did not engage into 3rd gear. Now the traffic was flying past me, I pressed the accelator to the floor in an attempt to avoid an accident and not be rearended. After several seconds, the transission engaged and the truck began to move forward at a slow pace. This is when I noticed on my fordpass app, saying powetrain malfunction/reduced power. I was able to get the truck to the closest gas station, where I shut the truck off. After several minutes, I restarted the truck and drove the truck to work with no issues. The next day, I took the truck to a local transmission shop. Where they indicated the transmission was shot and needed to be replaced or rebuilt.

This is my second time filing a report with the federal safety agency. I purchased the subject 2020 Ford F-150 around October of 2023 from a Chevrolet dealer in Ohio. The vehicle had approximately 19,000 miles at the time of purchase and was covered under the OEM factory warranty. I began having transmission shifting problems as commonly associated with this model of transmission that resulted in a rebuild of the CDF drum of the transmission. I was traveling on [XXX] between Atlanta and the Florida line when my vehicle experienced erratic shifting and a catastrophic loss of power that placed me and my vehicle in peril. I was able to safely exit the highway to allow the engine to cool down, and I elected to limp the vehicle at low speed on back roads to my destination so the vehicle could be repaired. This was the first failure of my transmission. After several thousand miles of this transmission replacement I experienced a sudden and dangerous loss of power while operating the vehicle at highway speeds in traffic on [XXX] between Orlando and the Georgia line, with the transmission temperature spiking to at least 255 degrees Fahrenheit . The Ford dealer confirmed the issue and isolated the failure to the valve body, which they replaced under warranty. This was the second failure of my transmission. After driving the vehicle for several hundred miles, the vehicle experienced a similar loss of power while operating at highway speed while I was traveling on [XXX] headed toward Atlanta. A motorist entering the highway disregarded the posted yield sign thereby creating a traffic hazard which I very narrowly avoided despite experiencing a catastrophic loss of power under acceleration as I attempted to maneuver my vehicle away from the offending motorist's vehicle. This was the third failure. My life and safety have now been placed in jeopardy three times. What will it take for the federal safety agency to adequately address this issue to protect the safety of the public? INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C.

I heard a weird noise last year and took it to ford. They ended up fixing the whole rear end, drive shaft, all components on the front end, They also replaced the whole 4 wheel drive system, and wheel hubs. last week I took the truck to have the pcm recall done. Once I left the transmission felt like it was slipping. I called them and they said that it is probably from the other issues I had to have fixed, and they would charge me 200 dollars to have this fixed. In the 4 years I have had this truck the whole drive train system will have to have been replaced. Ford needs to replace the transmission when they are fixing other drive train issues this is not safe when you are driving and then the truck will not shift gears
the truck has sudden jerking, Harsh shifting, The truck lunging forward unexpectedly, Hesitations during acceleration, Unexpected losses of power this is on a recall for several other 2020 f150 trucks and it never did this till recently
Transmission was slipping and multiple seconds delays in shifting. Delays were also observed when switching from reverse to drive. Rough shifting periodically as well. Took the vehicle to dealership and they informed me of a TSB on this transmission and they recommend overhaul/ repair. Quote for repairs between $6,700- $9,000 between multiple dealerships nearby. Vehicle has 113,00 miles.
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.

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.
