Transmission hesitated when entering traffic almost causing accident. This is not the first time this has happened. After the first incident I addressed the issue with the service manager. He said it’s common that this model transmission shifts rough, and has some hick ups but, nothing to worry about. It also randomly shifts into neutral randomly.

Transmission stalls, shifts hard, shutters,. Had the transmission rebuilt about four months agoand similar issues are already starting with the rebuilt transmission.

i bought a 2020 ford expedition with the 10r80 transmission last july. They have used this transmission since 2017 and continue to put it in vehicles depite having many issues with them. When i was sold this vehicle i was told it had a new transmission just put in it (by another dealership than who i was buying it from) and the carfax (that i still have) shows that the transmission had been replaced. In the last month or so ive been having a hard shift at 4th and 8th gear. i figured it would be covered under warranty so i take it back to the dealership that did the work. They said it didnt have a new transmission only the cdf clutch was replaced. now when i look at the carfax it only shows the tranmission was rebuilt. Thats Fraud. a dealership shouldnt be able to change a entry. i was only 2231 miles over the powertrain warranty and ford will not help. the part that was fixed only had a year warranty and it just a month past a year since it was repaired. Ford knows this tranmission has problems and should be held accountable. i look forward to hearing from someone.

My check engine lights comes on and off reading that it is a failure with the catalytic converter. Check engine light had been on for 2 weeks I had already called Ford to set up appt. The evening before taking truck in check engine light went off. I called Ford 5/13/25 that light had gone off do I still take truck in. Since I received letter for recall, I took truck in for service . They say they only need to reprogram the PCM but now they are saying that the Catalytic Converter is bad and needs to be replaced costing $5000. What is Ford thinking this truck has been nothing but problems. I told tech that truck has been running accelerated for a few weeks when driving. Problem with check engine light could not be reproduced since it turned off the day before I had appt set. Rep told me that they just needed to see if they could read that it was the recall issue and they would just reprogram it.

When accelerating quickly, such as to pass, the truck feels as if it is in neutral. when the gas pedal is pushed down, the RPMs jump up, but the truck doesn't accelerate. After letting off the gas, the RPMs will drop, there is a loud "clunk" in the rear end and then power will be restored. No codes are being stored to diagnose issue. Happens intermittently and all speeds.

At 45000 miles the transmission started slipping gears, we took into our local ford dealership for a warranty repair. They had it for a month and a half stated the computer just needed reprograming. Well now we sit at 72000 miles and the vehicle needs a WHOLE new transmission. They are stating that due to axial movement of the CDF clutch cylinder bushing it has caused failure of the transmission. My vehicle has came to a complete stop no warning multiple times in the middle of the roadway, I have been stopped at a red light and when I hit the gas, the car rolled backwards. There were ZERO warning lights, only a hard shift every now and than. The car is currently at the dealership and ford is refusing to help even with multiple other vehicles with this same issue. They have sent me a 10k bill. From my understanding this same transmission has already been recalled in other ford vehicles.

The vehicle's transmission shutters upon rapid acceleration, especially at high speeds. It feels like it goes into neutral while trying to shift and jerks into the next gear. The RPMs shoot up and back down when this happens. You can also feel the car lose power (decelerate) when this happens.

A 2020 vehicle with 80K miles is in need of a new transmission, after having hard shifting problems a few months previous. Rarely used for any towing. Appears to have a defective transmission.

We have replaced our transmission twice and sending the truck in for a third replacement. The transmission does not run smooth and when it shifts from 3rd to 4th gear it drops into gear very roughly. The last time it did this the TCM also faulted which stuck the truck in 7th gear while driving on a highway. Ford will only replace with the same part in a manufactured condition.

The transmission failed. It is being rebuilt when the dealership can get to it. So it's available until then. The transmission would slip, lag shifting or slam into gear sporadically and unpredictably. This caused inconvenience at best and erratic vehicle behavior that endangered myself and other drivers at worst. This has been confirmed by the dealer who recommended a rebuild with improved parts to correct this know condition/failure. Yes the Ford dealer inspected the transmission. There we never any warnings or messages to indicate anything is wrong. The symptoms progressed for a couple days before I brought it to Ford.

My vehicle without notice just pops into neural and i get a warning on my dash it has happened several times and every time it has happened it has been on a busy freeway. Very dangerous conditions . I have taken into the ford place to get checked out. also my Ford app had notifications.

While driving on a highway at approximately 40mph, attempted to pass a slower vehicle. I accelerated and the vehicle dropped down in gear, started shuddering, lost power and the MIL light started flashing. I pulled to the side of the road and the vehicle shifted into another gear and seemed to operate normally. Vehicle is currently at the Ford dealership, where they say that I need a new transmission.

Transmission, it is available for inspections. Loss of acceleration power while at interstate speed, the otr driver behind us could barely stop quick enough. Two more occurrences happened same trip while driving from New Orleans to Lake Charles. Driving 75 in left lane, took foot off accelerator to coast and navigate into right lane and while transmission was supposed to be downshift, I lost power again and watched my RPM’s rise suddenly. Ford dealership ran diagnostics, and told me the valve body needs replaced at roughly 2k, I am 15000 out of warranty and they acted like they knew but wouldn’t help me. An independent transmission dealer in Lake Charles told me to trade the vehicle in or put a 2025 ford transmission in at 7k, the problem is, I don’t have that kind of money, and this should absolutely not be happening at 85k miles. He insisted the transmission was damaged and dangerous to be driving, and this is prevalent with the type of transmission in fords and chevy’s from 2019-2024. No warning lights or alarms came on at the time of these incidents that I recall, honestly I was too busy making sure I didn’t kill my wife and 4 kids. Apparently, this is a well known issue with these transmission, but now I’m faced with having to either trade in a vehicle that I am most likely upside down on, to no fault of my own, having to purchase a new vehicle that fits my family, or purchasing a 2025 ford transmission at the recommendation of local transmission dealer, there is no history on ford 2025 transmissions so idk if this the way to go. While I will get this figured out, I am taking the time to express my personal concern and experience in this matter and hope there are no future casualties related to this issue, which I’m afraid Ford will only address if there is, sadly.

I was driving my vehicle at 48 mph and went to accelerate; the car slips out of gear and drops into neutral, started smelling smoke. This is the 5th occurrence. Previous occurrence happened while traveling in dark, rainy weather on the interstate. I am lucky that no accident occurred. I had car serviced for this same issue in 8/2024, but they did not fix the transmission issue. The vehicle is currently at the dealership service department. The dealer has been unable to reproduce the issue as it has happened a handful of times and does not give the service department a diagnostic code upon diagnosing. The dealer service department inspected the vehicle and is saying that I need a whole new transmission, although the first time I took it in for the same issue they fixed the throttle body, which is completely unrelated to the transmission. At the time of all of the incidents, the car flashes a "system fault/failure". It happens so quickly I cannot remember exactly what it says. When service department tries to diagnose there are no diagnostic codes. No warning symbols appear on dash after car is shut-off and restarted. This seems to be a known issue with Ford 10-speed transmissions (10R80). Why have they not had to recall these? I am lucky that I have not injured in these incidents. Are they waiting for someone to get critically hurt??

Several times per month, At normal highway speeds, vehicle slips out of gear into first gear. Vehicle also grinds through gears when searching for correct gear. Transmission shifts hard under normal conditions when up shifting to third gear.

The transmission on my Ford Expedition is "slipping" and causing safety concern when there is a need to accelerate or decelerate, but the transmission is struggling to shift into 8th gear and then when it finally does, it causes an abrupt jerk. This has put my family in at risk several times, but we had an incident this morning and I decided it needed to be reported. The dealer was able to inspect, diagnose, and confirm that the issue was that the "CDF drum that holds the gears in the transmission." The issue was repaired under the existing powertrain warranty, however, the exact same issue is now occurring again for a second time a few months after the initial repair. This leads me to believe the parts are faulty and need to be replaced with a different/better part. I also want to share that this issue is being experienced by other people that I know who drive newer Fords. There were no warning messages or lights the initial time or this current time.

The contact owns a 2020 Ford Expedition. The contact received notification of NHTSA Campaign Number: 25E070000 (Power Train); however, the part to do the recall repair was not yet available. The contact stated that he lived near a School Zone and was concerned that the failure could occur, causing the vehicle to strike and injure children on the road. The local dealer was not contacted. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue and advised the contact that the vehicle was safe to drive because the recall was not a safety recall. The contact had not experienced a failure.

2020 Ford Expedition FX4. Towing a four wheeler and motorcycle on the expressway. The suv was in tow / haul mode and on cruise. The car downshifted to go up a incline and made a booming noise and then composed its self. Shortly after, I tried to pass a car, and the trans downshifted, made a couple of loud clunks, shuddered, lost all power. After a couple terrifying seconds it composed itself, found gear and maintained speed, acceleration was not possible as the trans would go out of gear. Further down the road, it did the same thing, clunk, clunk out of gear, no power. There were NO warning lights. I took it out of tow mode and tried both sport and standard settings, both had similar issues. This was the scariest situation I have ever been in with a car mechanical issue. Note: We were ~120 miles into the 160mile trip. The OAT temperature was ~45 degrees. Trans temp showed 250 degrees when acting up, and dropped to 220 by the time the trip ended. Odometer shows ~77k.
