general problems of the 2018 Ford F-150 - part 2

When driving transmission has issues in low gears specificially when starting from a stop and accelerating, often shifts very hard, or shifts into neutral and engine just revs. Very unsafe in all aspects as normal accelration does not take place. I have taken it to my local mechanic who advised that this is just how these transmissions are, and my next step will be to take it to Ford directly. "check manual" light pops up w// a wrench.

I have a 2018 Ford F-150 platinum truck. The truck began hard shifting and jolting the truck while slowing down or speeding up. Threw codes p2707/p2708 (f-clutch solenoid); the cdf played part in this issue. I lost several gears (to include gears 1-3, 5, 7, and 9 in drive, and reverse) while driving. This was extremely dangerous and I needed a follow vehicle to stay at a safe distance to escort my limping truck to a safe place. Ford dealership quoted $11,800 to replace transmission. Mom/pop shop offered $9,000.

When driving my vehicle, 4 and 5 gear shift very jerky and harsh and sometimes seem to slip. Multiple times now I have had it go to shift into 4 gear to then drop in neutral and stop taking throttle causing me to suddenly stop going forward. Many times when trying to cross an intersection or go from a stop light I have a missed shift in those gears causing a high chance of injury from being rear ended because suddenly I stop moving forward with no reason. I haven’t had any warning lights for this issue and I’ve had a shop look at it and have all the same issues happen. When towing it’s much worse causing it to slam into gear at very high rpms. When very cold out it happens every time and I have to let my truck warm up for 15 minutes before leaving because it will drop out of gear. I’ve seen many reports of the 10 speed having many problems and I’m afraid one of the times it doesn’t shift right I will end up rear ended because of something I can’t control. The location I will put in when I was towing, crossing a 2 lane highway and trying to get up to highway speeds with the transmission slamming into gear really worry’s me for not only my safety but others driving on the road.

Cdf drum failure which is a known issue by Ford on these trucks. It causes the truck to shift on its own no matter the speed and sometimes randomly come to a complete stop. Year model trucks from 17-22 are all at risk of this issue before reaching 100k miles. My issue was diagnosed by the Ford dealership and I called a transmission shop for a second opinion and they immediately knew what I was referring to since it is so common. No warnings or check engine lights when the issue is occuring.

The vehicle has 57000 miles and I am reporting a commonly known issue with the transmission. Despite multiple service appointments with Ford explaining the issue, I was informed there was nothing wrong. Now, 10 months post extended warranty, Ford is telling me it needs a full transmission replacement. Thoroughout, the vehicle shifted eradically up and down, including on the interstate, quickly dropping speed. It was particularly bad a lower speeds when the engine was cool. Sometimes, at low speed or at a stoplight, the vehicle would disengage the drive train and roll in neutral while the rpms revved when the throttle was pressed. The vehicle was not operating safely, would roughly bounce around gears, when reported to Ford, told that there was nothing wrong and now being told post warranty that the transmission is a total fail that will require replacement. The latest service appointment one month ago, where I was again told that an oil topoff was all that was needed. This is a well reported safety issue by numerous owners and Ford has failed to take any action or initiate a recall.

Issue with cdf drum in transmission. Having transmission rebuilt due to failure.

10r80 transmission has started to go bad like all the other complaints. Cdf drum walking, valve body leaking pressure, torque converter bearings are whining and getting louder. Flaring between gears and now at highway speeds from 9th gear to 10th gear is has a flare then goes into "neutral lockup" and tries to go back to 1st gear. Thankfully, it hasn't actually locked into 1st gear but this happens frequently and is a major life threatening defect now. I am afraid to drive the vehicle and Ford motors knows there is an issue (for years) and has not created a recall for my VIN.

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.

Transmission failing caused me to almost get in a collision on multiple occasions. Most recent incident failed to go into gear and was almost tboned.

I was on spencer street at the light about to cross on saint rose park way. When the light turned green my truck wouldn’t let me proceed and the it went into a low gear and make a lot of noise until I crossed and stoped at the horizon ridge light. At the light I turned off the truck like I have done every time this had happened after Ford said they did the recall but after they did the recall I’ve been having all these issues. I turned the vehicle back on and put into into drive and it went into reverse I immediately pressed my brakes knowing there is a car behind me. Thankfully the guy saw the truck with the hazards and going into reverse he immediately went into the next lane. I couldn’t move I was stalled. Had the shut the truck off again and then turn it back on and then I was able to go into drive and sit on the side of the road. Meanwhile I can smell like this burning smell. Now this had happened 2 days after they came out to supposedly fix the recall that was on the truck. I didn’t work the next day after they came out to fit it at my job but driving home that day it drove sort of ok I felt a little lack of going into gear. When I went to work it did a hard jerk while driving like if the transmission was going to fall out. I parked at work for my 10 hour shift and when I went to go home I turned on my truck and out it into drive and it went into reverse. Thankfully I was in park and no cars was behind me. I called Ford to tell them what had happened after they came and fix it and they told me it was not part of the recall. But yet when I looked up the recall when my insurance let me know if it people was saying they was having issues going into gears and possibly stalling. This is a serious matter and they keep brushing it off and telling me that I need to pay them to look at it. I don’t feel I need to pay if it is their mistake. I took it to my warranty company and they tried to fix it and found nothing on their end. At this point I gor into almost 5accident.

Slams in reverse and when shifting in some gears with the 10-speed transmission. The cdf drum is a major issue with the 2018 Ford f150 due to the design defect in the drum. Ford recalled some trucks for the drum issue, but my VIN # shows no recall. This is a major expense issue due to Ford's design, and I feel should be a recall issue.

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 national highway traffic safety administration investigate this issue to determine whether it represents a broader safety-related defect affecting other vehicles of the same model and model year.

Sudden transmission downshifts to 1st gear during highway speeds. My truck wasn’t included in transmission recalls by Ford. This problem is known but Ford won’t replace. The downshift happens without warning. No engine lights or messages appear before or after the downshift. The transmission shifts harsh no matter what - this has been confirmed by multiple mechanics and the mechanics say it’s a known issue with this year transmission - 18’ - 10r80.

Transmission failed at 52,120. 0 miles. Erratic shifting and power loss. Cdf drum failure.

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.

218 Ford f150 5. 0l 4x4 with 10r80 transmission. While accelerating from stop light and attempting to merge into highway traffic flow, transmission shifted to 4 gear and failed to actually change gears resulting on a massive loss of momentum and causing a dangerous situation for myself and other motorists. This was an unknown problem to me, but after doing some research, a very well known problem to Ford. The company has used this transmission in many models of their vehicles and generally results in a full rebuild of the transmission to properly correct the issue. As of today, there are class action cases for this. Ford has correct the know deficiency in the latest (2025+) versions for the transmission, so there should be a recall to correct the problems with previous versions. Ford motor company has known about the defect with the lack of lubrication on the cdf drum, as well as other issues, and sold the defective parts anyway. This incident did not result in an accident, but only because traffic was light enough that other motorists were able to swerve around me. This particular highway access does not offer an emergency lane until after the bridge the the onramp spills onto.

The transmission shifts very hard into 3rd gear. Now it seems to slip going into 3rd,5th&8th gear.

The truck will downshift without warning causing an abrupt slow down in speed something is wrong with this transmission Ford should recall this transmission and make it right.

I recently had the 10r80 rebuilt due shifting issues and it was discovered that the cdf drum and the outer shell were defective. The transmission would shift erratically and sometimes would shift into a lower gear that should not do causing immediate high engine rpms and throwing passengers forward. In wet conditions this would cause a loss of control. I retained the defective parts and documentation of the rebuild.

Transmission failure from cdf drum. Well known issue with Ford f150 at this point. Vehicle was purchased new with standard regular maintenance. Only 56k miles. Safety issue if I hadn’t caught it early with some rough shifting.

Our vehicle has 79,500 miles and the transmission is slipping between 2nd and 3rd, and causing rpm surging. We had a diagnostic done and need the cdf drum replaced with the newly designed part as the current part has a defect. This is apparently a known issue and should be a recall so the defective part can be replaced. This will cost me 7k to 9k to either rebuild or replace my transmission.

Truck has 80,000 miles on it. For the last few thousand miles, the transmission has started to lurch during gear shifts from low speeds causing the vehicle to feel as if it is stalling out. Dealer states it is designed to do this, but due to power loss a collision is a possibility while trying to enter onto a highway with faster speeds. Dealer states the vehicle is learning the driver's driving behavior. After 80,000 miles the vehicle already has learned the driving behavior and there is something else taking place. The vehicle does not throw any warning codes when attaching an osbii reader to the port. Taken to an independent shop and was told this is a known issue with the 10 speed transmission in the 2018 F-150 vehicles that Ford has not fixed until 2025 and up year models. This is a safety issue at the very least.

Transmission failure.

This is the 10 speed transmission. When starting from a stop the truck will start to shift thru gears and then shift into neutral and the engine will rev very high and then slam back into a lower gear.

While driving approximately 40- 50mph the transmission randomly downshifts from 8th gear to 1st gear.

I have a 2018 Ford f150 and the 10r80 transmission has failed on my truck. It started with hard shifts and missed gears. The Ford dealership in tracy, CA quoted me $13k to replace the transmission because of known issues with this transmission. There are multiple tech service bulletins but they are making Ford owners pay for these costly mistakes from the manufacturer. I was at a 3 way intersection on a busy highway in the morning and the transmission all of a sudden had a loss of power and wasn't in a gear when it said it was in 4th gear. Very dangerous to lose power like that in the morning at a busy intersection. I had to have my truck towed home as I couldn't not make home with all the problems that started occurring.

Harsh shifting from failing clutch drum.

While driving on the interstate, the vehicle experienced a sudden hard jerk followed by erratic shifting between gears. The transmission temperature rapidly increased (over 219°f), and transmission fluid began leaking. The vehicle became unsafe to drive and had to be pulled over. This vehicle is equipped with a 10-speed automatic transmission (10r80), which has widespread reports of failure, harsh shifting, and overheating. The failure created a dangerous situation as I was stranded on the side of the road with my children.

The transmission shifted from 10th gear to 9th gear and then to 8th gear on a flat freeway going 70 mph. It quickly reduced our speed causing vehicles behind us to brake hard so as not to crash into the back of us. Ford and the dealership have been no help because of the transmission being out of warranty. Ford knows there is a problem but refuses to fix it. Customer service and safety is not more important to them than profit. There were no warnings before it happened. It has happened more than once. It also happened on i80 in 2024.

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 vehicle’s 10-speed automatic transmission is experiencing severe, erratic, and life-threatening failures at highway speeds. Erratic shifting & sudden downshifts: while traveling at approximately 60 mph, the transmission unexpectedly downshifts from 10th gear directly to 1st gear without warning. This causes violent deceleration and risks immediate rear-wheel lockup. The vehicle also cycles randomly through gears (e. G. , jumping 10-1-7-10-3) and frequently 'locks out' upper gears, making power delivery completely unpredictable. Total loss of motive power: on approximately 3/10/26, while in the high-speed 'fast' lane of the highway, the vehicle experienced a complete loss of motive power. While the engine remained running, the digital gear indicator on the instrument cluster began flashing and the transmission failed to engage any gear. I was left coasting in the flow of traffic and was forced to navigate across multiple lanes to the shoulder without the ability to accelerate. Safety hazard: these combined issues create an extreme risk of high-speed rear-end collisions and loss of vehicle control. The 'flashing' gear indicator and sudden visible on the dash 10-to-1 downshifts suggest a critical electronic, sensor or software failure that makes the vehicle unsafe for highway operation.

My 2018 Ford F-150 had 85,000 miles on it when the transmission began to slip out of gear, delays in shifting, gets stuck in neutral, and or slam back into gear. My wife was barely able to get home from work, and experienced dangerous driving conditions due to the failing transmission. Her attempts to merge onto high speed roadways became dangerous when the vehicle would suddenly lose drive during the merge. We fear what might have happened if she was attempting to make a left on green and the transmission suddenly became stuck in neutral. This truck has the infamous 10r80 Ford 10 speed transmission that thousands of people have reported as defective. Ford has refused to compensate me in anyway, and the Ford dealership has quoted me $9,000 dollars to have the transmission replaced. Ford issued a TSB on this faulty transmission, but has refused to issue a recall despite the widespread failure of this part and the safety concerns.

The contact owns a 2018 Ford F-150. The contact stated that while driving approximately 65 mph, the vehicle stalled. The vehicle was pulled over to the side of the road, shifted into neutral(n), and restarted the vehicle. The message "see owner’s manual" was displayed, and the transmission warning light illuminated. Additionally, the transmission skipped from fourth gear, slammed into tenth gear, and then stalled. The contact switched the vehicle from automatic to manual mode to accelerate normally and drove to the residence. The vehicle was taken to a dealer, where it was diagnosed with transmission failure. Dtc: p20703-00 and p2704-00 were retrieved, indicating the cds drum and clutch had failed and needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 117,000.

1. 10r80 (cdf drum bushing) failure. The vehicle has pressure loss when put into gear, driving or slowing down, taking your foot off the gas, sluggish when put in first gear to drive, performance, and harsh shifting- at any speed when driving, missing gears - it' jolts hard (shifting up or shifting down) when the vehicle shifts, particularly between gears 1–3, 3–4, 6 - 8 it misses 2nd and 7th gear. While driving the vehicle it goes into to neutral despite being in gear. The vehicle has stopped on the road while driving and not able to put the vehicle into gear to drive at all. Wrench light codes p0732-00, p076f-00, p07f6-00, p07f7-00, u0252-00 yes the vehicle is available for inspection upon request. 2. Our safety is at risk since the vehicle suddenly changes gears up or down causes major jolt sitting in the seat and abruptly slows down on the rode with traffic, or if you slow down or stop it might not go back into gear. I have had back surgery (lumbar) and it hurts my back. Not to mention, the whiplash to our necks every time the vehicle jerks in and out of gear. Vehicle suddenly slows down making it dangerous for vehicle around us as well. 3. We first took the vehicle to macon auto repair 2/23/2026 (no codes at this time unable to determine the problem), 2/24/26 took the vehicle to rodney's transmission for a second opinion - they checked the transmission fluids and added one quart of oil (still no codes to determine the problem) . The wrench appeared after the problems started and is whey we took it twice to two different shops not knowing what was the problem. When the wrench appeared we took the vehicle to rodney's transmission 4/2/2026 where the vehicle was inspected and the codes are from the diagnostic test done by, rodney's transmission, thompsonville, ky 4. Symptoms yes, described above. Warming light not until after the problems continued to occur.

Transmission is mis-shift and jerk while shfting. There's a lag between 6 and 8th gear.
