Since my initial purchase in 2020 I have had issues with the 10-speed transmission. The vehicle often shifts hard from gear to gear, banging harshly, and the vehicle pauses between gears while driving. While my vehicle was under warranty, I had the truck in the Ford dealers shop 5-7 times for that issue with no resolution. I even spoke with Ford back then about this and what happens after the warranty runs out. Even when I had my truck serviced (for my transmission) by another Ford dealership, I heard the comment "Oh yeah, it's the 10-speed transmission". Well, here I am, and my truck has consistently maintained the symptoms even after "repairs" were performed by the dealership, now the truck is so bad it is a road hazard for other vehicles by pausing, shifting out of nowhere, and such poor performance that I had to take it back to Ford and was told that the Transmission needs rebuilt...money out of my pocket that Ford should have fixed while under warranty. Will a rebuild really resolve the recurring issues??? While investigating this issue I found this this is a recurring topic on several forums and even your site lists numerous complaints of this known issue by many Ford owners experiencing the same exact same issues with this transmission. With the volume of complaints, how is this not a recall? Is there any other recourse for us?

Ford’s 10R80 Transmission is PLAGUED with issues. I own a 2020 Ford F-150 with the 2.7L V6 engine that has the 10R80 Transmission and this car has nearly gotten me in a T-Bone collision on NUMEROUS separate occasions. The transmission will slip as you’re first starting to accelerate, giving you zero control over the car and the RPMS will shoot up surpassing red line. This transmission is extremely clunky and downshifts extremely rough as well. This transmission is genuinely a safety concern when at intersections, accelerating from a turn etc. This transmission needs a recall IMMEDIATELY as I’ve talked to a LOT of other F-150 and other Ford owners that have the same 10R80 transmissions and have the exact same issues. This is a SAFETY CONCERN for ALL Ford owners with the 10R80 Transmission!!!

In March 2024, my F150 started hard/miss shifting. Between 3,4 & 5 gear. Ticket to Mount Ford dealer and they informed me the that the transmission need to be either rebuilt or replaced.I was informed parts to rebuild were on back order. Because Ford was having lots of issues with the 10R80 10 speed transmission. So I had to get a remanufactured one.

Transmission issue, took it into the shop not for the issue. Dealer called and stated transmission is making a noise and should be repaired/replaced. This is an everyday vehicle used 90% on highway driving. No warning signs or devices.

When the vehicle is cold, and the transmission has not yet warmed up, putting the truck into gear results in a significant jerk. Specifically: Initial Gear Engagement (Drive/Reverse): When shifting into either drive or reverse from park, especially when the engine is cold, there is a noticeable delay before the gear engages. This delay is followed by a harsh "jerk" or "thud" as the gear finally engages. Reverse to Drive Transition: When shifting from reverse to drive, a similar delay and jerk occurs before drive engages. Hard Shifting: In addition to the initial engagement issues, the transmission exhibits delayed and harsh shifting for several minutes when cold. Shifting is not smooth and seems delayed then shifts very hard and aggressively when driving during the warm up period. Clunking Noises: While driving, I intermittently hear clunking noises when the transmission shifts gears. This occurs at [ Mention the specific times or driving scenarios when you observe this - e.g., "low speeds," "during upshifts/downshifts," "when accelerating," etc. ]. These problems are most pronounced when the engine and transmission are cold and seem to gradually improve (though not completely disappear) as the vehicle warms up. I am concerned that these symptoms indicate a serious problem with the transmission. I have asked a Ford Dealer to look at this and they state that there is NO RECALL for my VIN #. They have always appeared since I purchased this truck.

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.

This is my second time filing a report with NHTSA. 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 NHTSA to adequately address this issue to protect the safety of the public?

Transmission failure at high speed. To low power..

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
