The transmission was already rebuilt under warranty, had 49,700 miles. While traveling between 70-80(while passing)open road the transmission tried going into 1st gear happned a few times until went into limp mode. Just me, no trailer, nothing in the bed. The dealership nor corporate would do anything since I had turned off the truck. Even though the codes were stored.
2020 Ford F-150 transmission complaints
Page 4 of 13: complaints 71 to 100 of 364, newest first, as owners wrote them.
Transmission shifts hard and downshifts with a huge clunk. Jerking the vehicle very big known issue for these trucks and am extremely low miles. Under 50k miles A bad safety issue and huge repair bill for the consumer.
The 10-speed automatic transmission in my 2020 Ford F150 slips between gears and has failed to engage from a stop in multiple instances. There are no warning lamps or other indications that anything is wrong with the vehicle. The issue is known as a very common problem with this transmission, as confirmed by multiple mechanics when inquiring about a potential fix.
F150 220. ford has been contacted before about the 10 speed transmission down shiften hard, or trying to excel and hitting hard. they said they knew of the problem. but only suggested in reset the computer " basically undue the battery " but the problem is still there. they stated the 10 speed was the worst transmission ford ever put in this vehicle.
Transmission disengaged while driving rendering the truck immobile in traffic. This occurred on multiple occasions. No warning lights or indicators of vehicle problem. Diagnosis and condition/issue reproduced by a Ford dealer resulting in complete rebuild of the transmission. This vehicle has the 10R80.
Having hard or delayed shift as described on TSB 23-2123. What I see dangerous is momentarily downshifts from 4th to 1st.
Driving down the highway at 70mph the truck dropped from 10 gear to 1st gear while losing speed I tried to accelerate to maintain safe speed but did not have power. The car jerked back to 8th gear then back down to 1st gear. Eventually back up to 10th gear but not full power. I was able to pull to the side of the road and turn the car off. After turning the car back on, the yellow wrench symbol disappeared from the dash and I was able to drive. The transmission now skips gears and does not have full power when accelerating. It felt extremely unsafe going 70mph then suddenly being in 1st gear losing speed as other cars continue around me at highway speeds and my car is decelerating without me using the brakes. There were no prior indications of this fault, my car was even serviced at a Ford dealership 2 months ago.
When starting the vehicle, while the vehicle was in park, it acted like the vehicle was in drive and surged forward. This is unsafe and needs to be addressed by Ford.
The 10R80 transmission has harsh erratic shifting. The transmission will occasionally launch when downshifting into first gear when pulling into my driveway causing me to almost hit the front of my garage. The transmission also has harsh clunking when shifting gears and will clink and throw you forward when downshifting in traffic.
Transmission gear shifting isn’t smooth. This has been occurring for 50k miles. Often going into one low gear to the next will hear a “clunk” sound.
Transmission has hard shifting, skips 2nd gear and sometimes will downshift out of 10th gear.
As I was driving my truck down the highway at 60 miles an hour, it tried to downshift to first gear several times. During that same time it lost several gears in the transmission. Ford is now replacing the transmission which is going to cost me a significant amount since the vehicle is just barely out of warranty. The truck did not have any prior warning lights or codes. It was hesitating to shift between gears occasionally for the last few thousand miles. This was an unsafe situation because the tires could have locked up and caused me to slide off the road at a high rate of speed. The dealer called after the diagnostic and essentially said "there's no way around it, this truck needs a whole new transmission and parts related to the transmission replacement.
My family and I were merging onto the highway when without warning, the automatic transmission bucked, making a loud thump sound, then it lost power nearly causing a severe accident. The transmission then began to hunt for gears, seemingly confused. It even cycled through 1st gear, my heart dropped, but luckily it did not engage 1st gear since that would have caused havoc at highway speeds. Afterwards, the vehicle regained some power but was suddenly limited to only two gears (5th and 9th). I immediately drove home, when entering my driveway the transmission could not engage reverse. Therefore I had to roll it in using forward momentum. I just had the vehicle serviced a few days ago because this issue happened before (not as severe). However, I was told the vehicle was operating fine and a leaky transmission pan was the culprit. After the transmission pan was replaced, I picked up the vehicle just yesterday (4/11/26), and this incident occurred today,(4/12/26). Please help, this transmission was rebuilt by Ford under warranty (60k mile powertrain warranty) just two years ago due to the notorious defects that have been ongoing. I contacted Ford corporate but they've refused to provide any help. This problem was confirmed by Ford corporate and the dealer, which led to the initial transmission rebuild (in 2024). However I fear this defect may not be repairable since the issue has returned and is more severe. I believe Ford was aware of this defect and did not disclose this information to me prior to buying. If I had known, I wouldn't have purchased this vehicle. Thank you for any support you could provide on this matter.
The vehicle just downshifted from 6th gear to 1st gear on the freeway nearly causing a accident and it caused a blown transmission.
The vehicle has less than 95,000 miles on it. The vehicle was purchased with around 83,000 (11/15/2024) started having issues with the transmission around 85,000. The truck will go from 6th to 3rd or it may go from 10th to 1st while running a good speed down the highway or it pulls out fine then goes to neutral. This is a safety issue. There needs to be a recall made on this vehicle before it causes one of us to get hurt. Please have someone to investigate. We need this matter corrected and I do not feel it should be out of our pocket to correct it. Yes, we could trade it but we do not want someone else to get hurt. Seeing as how the dealership sold it to us knowing this was an issue I'm sure they would not fix it to sell it. No incident has occured at this time. I'm trying to be proactive in preventing that.
The contact owns a 2020 Ford F-150. The contact stated that while driving at an undisclosed speed, the vehicle unexpectedly downshifted. There was no warning light illuminated. The vehicle was taken to the dealer and was diagnosed with transmission failure. The contact was informed that the transmission needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 110,000.
My transmission unexpectedly jumps gears and down shifts. My car just stopped getting any sort of power on the highway. All this with my children in the car. I was able to pull over safely, but it was extremely scary. I put the truck in park and then put it in drive and it started driving again. My ford f150 has under 80,000 miles on it. In my opinion this is a huge safety concern. A wrench popped up on my dash indicating that service was needed, but it has since gone away.
The transmission shifted unexpectedly from highway speed to first gear. The back wheels felt like they locked up and my passenger asked if we had been hit.

Hard shifting
Problematic transmission shifting with lower gears causing significant hard shifting and jerking motion while driving. The problem was confirmed by my local Ford dealership on 11/26/2025, who recommended an overhaul to the transmission and tear down to determine if further damage is present or if a new transmission is needed. There were no warning lamp indicators showing any earlier related matters.
Transmission issues. Random hard shifting. Random over revving due to improper shifting. Multiple components are being replaced. They are all heavily reported as issues in the transmission. The dealer refuses any remedy. No warnings show prior to the issue
Although my VIN was not listed on any data base as a risk of the 10-speed transmission issue, my transmission first faltered while driving on the highway on 26 November 2024 and then again on 9 December 2024. While driving, the transmission instantly downshifted to a lower gear and there was a loss of power, which was a huge safety issue while driving on I-44 at 70 mph. Ford was notified of both instances via phone call from me and through the Ford App that is linked to my truck. In both occasions, the "Engine" light on the dashboard was illuminated. *Please note that Ford did assist in repairing this issue through the Customer Satisfaction Program.* Although I was still responsible to pay for 55% of the repair amount (total of $6,608.82), Ford paid the remaining 45% and added an Extended Warranty to the truck for 36,000 miles / 36 months. A new transmission was installed on 18 December 2024. My reason for filing this is to add to the data that is being collected with regards to this specific issue. Yes, Ford may assist on a case-by-case basis, but this is still unfortunately being viewed as a "Service Bulletin" instead of a Recall.
Transmission at various times has a very hard drop to a lower gear, to the point where it will drop from a high gear to a lowe gear skipping the middle gears and the transmission/driveshaft seriously bangs when it does this.
My truck down shifted from seventh gear all the way down to first, making rev really high and slow down all the sudden. I was doing 50 mph
Oil consumption takes several quarts of oil before next oil change. Erratic and harsh shifting and sudden hard downshifts.
2020 F150 with only 63000 miles has a failed transmission. The truck doesn't shift gears properly, gets stuck in gears, loses power suddenly. This is a huge safety risk as the vehicle just stops accelerating or working when driving. This clearly endangers me and other drivers. Ford refuses to pay even though their check engine light gave a TRANSMISSION/POWER FAILURE alert and the Ford dealership inspected it and their diagnosis is: REPLACE COMPLETE TRANSMISSION ASSEMBLY. HAS INTERNAL CDF DRUM BUSHING FAILURE. This is an ongoing issue with these 10 speed transmissions on these F150s. There are several class action lawsuits against Ford over these 10R80 transmissions. Ford is not only refusing to recall these dangerous vehicles but also refusing to pay to cover the repairs on transmissions they've known are defect.
I bought a 2020 Ford F150 XL with 83,000 miles on 27 JAN 2026 from a local Phil long Kia dealership. I started to notice that the shifting was very harsh immediately after buying the truck and that the transmission was dropping the gear when I was driving at stoplights and even when I was entering an intersection almost causing an accident. I notice the issue more at slow speeds and in lower gears. Today is 19 FEB 2026. I brought the truck to a local ford dealership and they told me that the transmission needs to be replaced.
While driving my F-150 I made a turn and when I went to accelerate again, the truck acted like it was in neutral - would not go. Engine continued to run but would not accelerate. A second car was directly behind me and almost rear-ended me when truck failed to move. Pulled over, tried low gear and reverse and nothing happened. Transmission is shot. Currently in for a rebuild. This is the Ford 10-speed trans, which has been known to fail. I only have 33,000 miles on the vehicle. Could've been much more dangerous had I been on the freeway when it failed.
Transmission downshifted on the interstate and overheated. Wouldn’t go back in to gear. Was in the passing lane and ended in an accident.
