2020 Ford F-150 Powertrain (other) Problems

The contact owns a 2020 Ford F-150. The contact stated that while driving at various speeds, there was a delay in the transmission shifting, and the vehicle hesitated while accelerating with the accelerator pedal depressed, and the vehicle jolted. The engine revved to 7,000-8,000 RPM. The vehicle was taken to an independent mechanic, who determined that the transmission needed to be rebuilt or replaced. The contact associated the failure with Technical Service Bulletin: 25-2301 (Harsh/Delayed Engagement and/or Harsh/Delayed Shift) and Technical Service Bulletin 25-2475(Harsh/Delayed Engagement and/or Harsh/Delayed Shift). The failure mileage was approximately 88,000.

Truck suddenly shifted from gear 8 to gear 2 then 4 reducing my speed suddenly causing other vehicles to almost hit me at around 40 mph. I drove home with the transmission erratically shifting up and down Even though I kept my speed under 30 mph. That was about 10 days ago and I made an attempt to drive it a few days ago after researching and in the same result happened. It seems I have been victimized by the CDF drum crawling out of its space leading to an imbalance of transmission fluid pressure. About 2 miles after the initial problem. A wrench symbol appeared on the instrument cluster with a message under it that says see manual. Just as every time I've tried to find something in the manual. After spending several minutes of frustration, I still never found the wrench symbol or what it means.

The contact owns a 2020 Ford F-150. The contact stated that while driving, the vehicle jerked abnormally, experienced a transmission shifting delay between gears, and occasionally slipped out of gear. The contact stated that after slipping out of gear, the transmission failed to re-engage gear and slipped continuously. The vehicle was inspected by a transmission specialist, who confirmed the failure and determined that the transmission needed to be replaced. The manufacturer was notified of the failure. The failure mileage was unknown.

Transmission slips gears and sometimes shifts violently. I took the truck to a Ford dealership for an assessment and was told I need to replace the whole transmission. I also have a problem with oil consumption from the engine. I was told by the same dealership that this was a known problem with the 5.0 engines built from 2019 to, I believe 2023 and that it would require an engine replacement. I bought this truck from an individual and now I am stuck with it.

The 10R80 transmission failed internally due to the defective CDF clutch drum assembly. Vehicle experienced dangerous gear dropping/slipping. Forced to pay out of pocket at an independent shop for a total rebuild. I have not seen anything from dealer. It was inspected by an independent shop. There was no warning prior to the failure. This happened right over 100,000 miles.

Transmission shifted from 4th to 1st while driving a steady 25 mph, then lost all forward drive, the transmission slips, then will slam into gear. I parked it for two weeks until I could get it to the shop. Driving it to the Ford dealer today (2 September 2026) I had to stop the vehicle twice because the transmission was doing the same thing. Currently have 70K miles on it.

Incident

Aug 26, 2026

I am reporting a safety-related transmission problem I experienced with my 2020 Ford F-150 equipped with the 10R80 automatic transmission. While driving normally, the transmission shifts hard (ie: jerks, clunks) between 4-5 and 5-6 gears, and has on occasion failed to grab 1st gear when starting from a stop (revs, doesn't go). This occurred while turning across traffic, creating a potentially dangerous situation because the truck did not respond as expected when I needed predictable acceleration or propulsion. I believe this incident may be related to the known 10R80 CDF clutch-cylinder/sleeve problem. Ford technical information identifies axial movement of the CDF sleeve that can cause hydraulic-circuit leaks and harsh or delayed engagement and shifting. This condition can result in slipping, RPM flares, delayed engagement, unexpected gear changes, harsh downshifts, lurching, or loss of propulsion. This is a safety concern, not merely a transmission quality or reliability issue. Unexpected loss of propulsion or unpredictable shifting while merging, accelerating into traffic, crossing an intersection, turning, or traveling at highway speed can create a collision hazard. Because I personally experienced this unexpected transmission event, I request that NHTSA investigate the 10R80 CDF clutch-cylinder/sleeve condition in Ford F-150s. Please review Ford warranty claims, dealer repair records, transmission replacements, consumer complaints, and field-failure data to determine whether this is a safety defect requiring a recall. I believe owners should not have to wait for a potentially dangerous transmission failure before this known condition is addressed. Furthermore, I have already had two transmission rebuilds under warranty, and it's going back to the shop for a third time with the same issues 9/8/26. THE SAME ISSUES. I bought this truck in 2024 at 70K miles and it has been nothing but problems.

Went to speed up as I was approaching a ramp going uphill and almost towards the top the truck decided to down shift to first gear going about 45 mph. No accident occurred as no one was around me.

Incident

May 12, 2026

There has been harsh shifting observed, both cold and warm. Often when downshifting and slowing to a turn or stop, there is a violent slamming into gear. I have also observed slipping in 3rd gear and making harsh shifts that appear to skip gears by the indicator. This is not a constant but intermittent issue. I have not taken it to the dealership because they will likely not be able to duplicate it in a reasonable amount of time.

Transmission issues that are in line with what seems to be a well known 10R80 issue with a poorly engineered CDF drum. Transmission will randomly shift from a high gear down to first generating a ton of noise and impacting the handling. It has not become a permanant failure yet but is an extremely well known issue that always results in a transmission rebuild with updated/correctly engineered components at MY expense. I am worried it will cause a rear wheel lockup or a damaging amount of engine rpm one of these days. It is sporadic and isn't something that has been duplicated by a technician due to it being isolated and completely random in occurrence. It definitely seems to do it more often when it is cold out.

Transmission shifting issues. Have taken it to the dealerships and they stated it is "normal". Hard shifting and sometimes stalling out when trying to shift into first. The hard shifting on interstates is hazardous because it feels like the whole truck is about to lock up at highway speeds. Stalling is a hazard as well for my and surrounding traffic when it revs but suddenly wont move. No warning lights or messages displayed. Dealer is aware of the same issue affecting multiple vehicles with the same Transmission. They refuse to properly fix the issue stating its normal. It is not normal. Its concerning for my and my families safety. As well as the safety of others around me when driving on the highway.

Transmission started "clunking" and shifting erratically over a two week period before warning light came on that said "powertrain needs attention...contact dealer" Took the car to Monticello Ford in Monticello NY and they tested it based on diagnostic code and replaced filter and fluid. They reset the computer and told me to drive it for a week so computer could "relearn" driving habits. Drove truck for 4 days and once again transmission started clunking and shifting hard with loud thunks when transmission gears engaged. Had my [XXX] grandaughter in the truck with me on the highway when the transmission started to slip and would not engage. Other vehicles had to brake suddenly to avoid hitting me. Had to pull over and restart truck to get the transmission to re engage. Transmission issues have been a known problem with the Ford F 150 trucks since 2017 and yet Ford has done nothing to correct the problems with their customers.....there are currently three outstanding class action lawsuits against them regarding the faulty transmissions.....this is a SAFETY issue that Ford must be held accountable for and fix these trucks at NO COST to the customers who own these trucks immediately!!!

Our 2020 Ford F150 transmission failed at 80k miles. Ford USA offered to pay half of the repair cost but is not willing to take full accountability on a transmission that was never was put under stress. Our truck never towed anything and was only use to drive from the shop to the job site and with only 1 up to 2 passenger only max. Per google research: The 2020 Ford F-150, equipped with the 10R80 10-speed automatic transmission, commonly experiences harsh, erratic, or delayed shifting, sudden jerking or lunging between gears, and gear slippage. These issues stem from software calibration flaws in the adaptive learning system or mechanical wear on internal components. Common Symptoms and Issues Rough Shifting: Hard, delayed, or clunking engagement when shifting between lower gears, especially on cold starts. Lunging or Hesitation: Sudden forward surges or hesitation when trying to accelerate from a rolling stop. Gear Slippage: Temporary loss of power delivery or failure to catch the next proper gear cleanly. Shift Cable Clip Recall: A limited recall addressed a faulty shift cable lock clip where the gear indicator might show a different gear than what was actually selected, increasing rollaway risks
