Typical 10r80 transmission problems you’ve guys seen a million times and have yet to force ford to issue a recall . I can’t even make it through an intersection without it stopping suddenly and putting me in danger . Please do something. This is gonna cost me a lot of money to fix .
2018 Ford F-150 transmission complaints
Page 4 of 35: complaints 71 to 100 of 1,022, newest first, as owners wrote them.
The vehicle has gotten stuck in 7th gear before, it also has almost completely stopped, wouldn't accelerate and shifted down and up. It is not drivable now with only 58500 miles on it. I am afraid to drive it by myself and I would never take my family anywhere in it as it poses a safety hazard / danger.
I have been experience very hard shifts, lunging, and unexpected downshifting when driving. It happens every time I drive the vehicle. It happens at differenent speeds especially up on take off.
The contact owns a 2018 Ford F-150. The contact stated that while driving in 8th and higher gears, the transmission was shifting erratically, shifting hard, slipping, and shuddering. No warning light illuminated. The vehicle was taken to the dealer, where it was diagnosed that the re-manufactured transmission needed to be replaced; however, the dealer informed the contact that the repair was not covered under the federal safety agency Campaign Number: 25E070000 (Power Train); because the transmission currently exceeded 8,000 miles. The contact stated that the required mileage was not stated in the recall notification, and the recall remedy was not available when the failure initially occurred. The vehicle was in the process of being repaired under warranty. The manufacturer was notified of the failure, but no assistance was provided. The re-manufactured transmission failure mileage was approximately 8,000. The vehicle failure mileage was approximately 104,000.
Did Ford PCM recall, 2-3 days check engine light failed ignition coils $500, filed complaints with dealer and ford now o have another check engine light with faulty catalytic converter a recall for a faulty part from Ford should be all inclusive in its repairs it’s unfair for me to be out of pocket $2500
COMPONENT; likely the transmission SAFETY revs went to almost zero on highway. Transmission seemed to stop the truck. Then intermittent on and off transmission. Seriously struggled to get the truck off the highway momentarily no ability to control speed: then on and off with the acceleration. Very scary! sudden drop in speed on the highway could have caused an accident with no brake lights on Problem been reproduced: Not to my knowledge. its at a dealer now. Not safe to drive BEEN INSPECTED: At dealer now Prior warning - lamps etc: NONE WHATSOEVER Oil lamp came on, then the check engine light came on well after the initial scare.
The contact owns a 2018 Ford F-150. The contact stated that while driving at an undisclosed speed, the vehicle shuddered intermittently and had occurred on several occasions. No warning lights were illuminated. The contact researched and was made aware of an unknown recall; however, the VIN was not under recall. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure and confirmed that the VIN was not under recall. The failure mileage was approximately 111,000.
Transmission slips, cdf drum must likely the culprit, clunks to the point that the adaptive learning isn’t able to compensate for the cdf failure. Recently while driving at freeway speed there was a failure in the cdf drum That caused the transmission to go into limp mode almost causing an accident. Luckily I didn’t and after shutting down the truck and restarted it I was able to make it home very slow. It’s been parked ever since.
Transmission down shifted from 10th gear to 1st gear while traveling at 80mph on XXX. Truck then continued to shift randomly throughout gears and occasionally not shift at all. Clutchs are all burned up and the fluid is now burnt as well. Had to be hauled 2 hours home from an army installation. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
The contact owns a 2018 Ford F-150. The contact stated that while driving at various speeds, the transmission slipped and jerked. Additionally, when shifting into gear, the vehicle intermittently surged forward. At other times, the vehicle failed to move when the accelerator pedal was depressed. The failure occurred repeatedly. An independent mechanic inspected the vehicle and stated that a new transmission was needed. Repairs were pending. The contact had not notified the dealer or the manufacturer about the failure. The failure mileage was approximately 160,000.
The transmission will shift from whatever gear it is to a random lower gear usually 1-4
I believe this was a CDF Clutch Drum failure on the 10R80 transmission. Caused me to loose power midway through a signalized intersection. It is currently at the shop being diagnosed, but may be available for inspection upon a timely request. This issue put me and my family at risk because it caused my vehicle to stop in the middle of the road. No warning lamps, but the truck will no longer shift past 2nd gear.
transmission not shifting right and back up camera not cutting off while driving
when cold: - delays in shifts, sometimes up to a few seconds, hard jolt due to revs being too high once it finally shifts (really bad in 2nd gear, pretty bad in 3rd) - slight delay in overdrive gears sometimes (7th, 8th, 9th, 10th) after warming up: - delay upshifting into 4th and 5th almost always, even in manual mode - slight jolt downshifting into 6th at random: - gearbox gets confused and defaults to downshifting to 1st. this happens when accelerating. has happened upshifting to 4th, 8th, 9th. when this happens, it will actually downshift to 1st when attempting to upshift to 4th. when this happens while attempting to upshift to overdrive gears, it does not actually downshift (money shift) to 1st, luckily. - might be slipping a bit in 3rd or 4th gear
Ford F-150 have a known transmission failure problem which causes them to have to be replaced with low mileage due to the CDF drum. This causes the transmission to hit hard while the operator is driving which could cause them to lose control. Ford is aware of the problem and has refused to fix it.
I am submitting this complaint regarding a serious and ongoing transmission safety concern with my 2018 Ford F-150 3.0L diesel. The vehicle has repeatedly exhibited unsafe and unpredictable transmission behavior, including harsh downshifts at highway speeds, delayed gear engagement, slow transitions between gears, and abrupt jolting that can forcefully move occupants forward. These issues create a safety risk because the vehicle does not shift predictably during normal driving, including at highway speeds and during acceleration or deceleration. The vehicle was previously taken in for service due to these transmission concerns. At that time, the transmission fluid was found to be approximately 75% low. The dealer performed a software update; however, the transmission problems have continued and may have worsened since that repair attempt. Today, the vehicle displayed a transmission-related error stating: “The transmission control module has detected a concern when trying to shift to 4th gear. A failsafe logic disables 4th gear for the remainder of this key cycle.” This warning indicates that the vehicle’s transmission control module detected a fault during operation and disabled 4th gear as a protective measure. This is a significant escalation from rough or delayed shifting, as the vehicle is now entering a failsafe condition that removes a gear while the vehicle is being driven. The condition presents a safety concern because the transmission may downshift unexpectedly, hesitate, jolt, or fail to provide expected acceleration or power delivery. This could be especially dangerous while driving at highway speeds, merging into traffic, passing, towing, or navigating traffic where predictable power and gear engagement are necessary. The abrupt shifting and jolting are severe enough to physically move the driver and passengers forward, creating concern for loss of vehicle control or a crash. The prior service action did not resolve the problem.
My vehicle was shifting erratically until a repair was made. Ford acknowledges there is a issue and will not place a recall even though they manufactured a part to fix the issue with the CDF drum in the 10R80 transmissions not seating correctly.
Transmission went out on me at 100,653 miles. 10 speed transmission. Would stay in gear for a long time in 1st through 3rd. Shift super hard from 5th to 7th. At times going down highway it would say it’s in first gear and I would have no throttle for 5-10 seconds until it would show it was in 10th gear again, vehicle would be in “coast” mode on the freeway. Sudden harsh shifts when not warranted causing erratic driving conditions. Resulting in a $6429.58 remanufactured transmission replacement. As I came online to check issues with these I found a mountain of complaints with these same transmissions. Ford needs to offer a recall with the amount of cases on the 10r80 transmission failures, plain and simple. Absolutely wrong for a truck with 100,653 miles to lose a transmission.
Consistent shudder in transmission. Downshifting at odd intervals and vibrations when at driving speeds. Taken to dealership and told that is just how it does. Transmission temp abnormally high on longer trips and transmission slips when hot.
When you go to take off and pull into traffic the transmission will stall and not move. The transmission will shift into gear in about 5 seconds afterwards. Then it shifts erratic.
UNKNOWN Transmission jerking at low gears. Transmission randomly enters neutral when in traffic at low speeds when accelerating causing dangerous safety issues. Transmission randomly downshifts causing safety hazard. No warning lamps or messages. Started about 1 year after purchase and has progressed to more often
Vehicle: 2018 Ford F-150 3.0L Power Stroke Diesel I am submitting this complaint because my vehicle's transmission exhibits repeated and potentially dangerous operating behavior that has not been corrected despite service by a service shop. The transmission unexpectedly downshifts while driving at highway speeds without driver input. It is also consistently slow to shift into appropriate gears during normal acceleration, causing delayed power delivery followed by abrupt and harsh gear engagement. The transmission frequently shifts aggressively, resulting in severe jolts that force occupants forward in their seats. The shifting behavior is unpredictable and significantly impacts safe operation of the vehicle. I brought the vehicle to an authorized mechanic for diagnosis and repair. During the inspection, I was informed that the transmission fluid level was approximately 75% below the proper level. The diesel automotive shop performed a transmission software update and returned the vehicle to me. Despite these repairs, the transmission problems have continued and appear to have become more severe. The ongoing symptoms include: - Unexpected downshifts at highway speeds. - Delayed gear engagement and hesitation before shifting. - Harsh, abrupt shifting accompanied by violent jolts. - Unpredictable transmission behavior that reduces driver confidence and control. These conditions create a significant safety concern, particularly at highway speeds, where unexpected downshifts or delayed power response can increase the risk of a collision. Because the issue persists after dealership service and a software update, I believe there may be a defect affecting the transmission or its control system that warrants investigation. I respectfully request that the federal safety agency investigate this issue to determine whether it represents a broader safety-related defect affecting other vehicles of the same model and model year.
The truck suddenly downshifts hard and the truck slows down significantly, without warning. When it goes back into gear, the whole truck jolts and the transmission shifts hard. It has always shifted hard, but the dealer blames the 10 speed transmission “just does that”. They don’t know why. This report tells me to enter a single date, but it happens about every 1 in of 5 times we drive it, and has for a few years now. Again, the dealer tells us nothing is wrong and they can’t recreate it.
I think that ford needs to a recall on these 10r80 transmissions, I was driving a week ago and suddenly I went to limp mode. Went to gear one now transmission is hesitating
Transmission is failing. Up shifting it misses gears and slams into random gears. It has sent me off the road buy at 50 mph in 7th gear it randomly shifts to first gear locks the rear tires up and spins the truck out. The problem can be reproduced anytime you start driving the truck after its been off for a while. But that doesn't mean it can't start up at any time. no warning light. problem started around 78k miles. THIS IS DANGER
On 3 separate occasions while driving at highway speeds, the transmission has rapidly moved from 10th gear to 1st resulting in a rapid decline in speed. Additionally, this vehicle loses power between 3rd and 5th gear, resulting in hesitation that has nearly caused accidents on two occasions.
- Master Cylinder leaking into booster Pump. ~Lost brakes going 65MPH, had to drive into a grass area to slow down. No warning lights until I lost all brakes. - Transmission hard shifting and unreliable gear selection ~ This truck has missed gears when passing intersections and has almost caused a wreck multiple time. Transmission is unsafe for users to drive with.
transmission failure
Subject: Safety Defect Complaint – Sudden 10R80 Transmission Failure in 2018 Ford F-150 I am reporting a serious safety issue with my 2018 Ford F-150 equipped with the 10R80 10-speed automatic transmission. The transmission failed completely at only 93,000 miles, well before Ford’s first recommended fluid change at 150,000 miles. While driving, the transmission suddenly shifted from 3rd gear directly to 7th gear, skipping intermediates. This caused severe loss of power (“gutless”) or abrupt deceleration nearly to a halt. The erratic behavior created multiple dangerous close calls in traffic. I was able to get it to a Ford dealer. They confirmed total transmission failure and referenced a Technical Service Bulletin identifying a known component (CDF clutch drum/hub) that commonly fails due to excessive heat and inadequate durability. Replacement was quoted at approximately $10,000. I contacted Ford Customer Service, described the safety risk of sudden unpredictable shifts, cited the known defect in their technical documentation, and requested assistance. Ford declined any support or remedy. This premature failure, combined with erratic shifting and loss of vehicle control, poses a clear risk of crashes. I urge the federal safety agency to investigate the 10R80 transmission issues in 2017–2020 F-150s and require Ford to issue a recall or extended remedies to protect public safety. Thank you for your attention. I have provided repair records, dealer notes, and further details below.

Truck has reoccurring issue of shifting from 10 to 1 at highway speeds causing me to shift into neutral as to not WRECK. No check engine light or trans light, which makes proving it to dealer is impossible. Only happens once every few months. Through forscan I can see the OSS speed sensor drops voltage briefly then regains voltage. This is a very expensive yet very dangerous truck and ford needs to be held accountable before someone dies....
