Power Train Problems of Ford F-150 - part 2

Complete loss of transmission power, and gear indicator in the instrument cluster starts flickering like it is shorting out. The vehicle has been experiencing this for 2 weeks. This happens under acceleration mainly, and first occurred while entering a highway. The symptoms seem to match those presented regarding the lead frame issues presented on many forums.

Vehicle going downhill at about 65 mph shifted to lower gear and warning light (wrench image) comes on dash. Truck would not accelerate going up next hill for several seconds and then warning light went off and operation/acceleration resumed and secondary light also cleared this had occurred on another occasion but second warning light stayed on. Service station checked code and indicated that the code was for a sensor in the transmission which they cleared. Have had several instances of intermittent warning light and loss of acceleration which have cleared after several seconds or when I pulled off road and put it in park and then back in drive.

The contact owns a 2019 Ford F-150. The contact stated that while attempting to shift gear, the vehicle hesitated, jerked, or the transmission was slipping. The check engine warning light was illuminated. The dealer was contacted; however, the dealer was unable to service the vehicle for several months. The vehicle was taken to a certified mechanic, who diagnosed the vehicle with transmission failure, causing damage to the drums and seals. The contact was informed that the transmission needed to be replaced. The vehicle was repaired. The manufacturer was made aware of the failure and confirmed that the repair was partially covered under warranty. The failure mileage was approximately 102,000.

There was a sudden downshift at 50mph and a wrench icon showed up on my truck. I used on obdii scanner and the codes p0706 and p0707 showed up. My safety was put at risk because I could have been hit in the rear and my rear tire locked up. I got the repairs done for a leadframe install. Is there any way I can get reimbursed for the repairs made, because this was once a recalled issue.

Transmission has been clunking/shifting hard and occasionally slipping out of gear. Recently it slipped out of gear while turning through a busy intersection. My truck lost acceleration momentarily which could have caused the vehicle behind me to rear-end me or crossing traffic to hit me. Apparently there are widespread issues with Ford's 10r80 transmission. I took my truck in to be inspected and was told I needed a new transmission with upgraded parts due to excessive metal in the transmission fluid. My truck is only 7 years old with 71,000 miles on it. Ford knows their transmission is a problem and hasn't issued a recall. And they did not offer to help cover the cost of the new transmission which totaled $9,645. 19.

When I was driving on the highway I was going about 65 mph in 6th gear and then without warning my 2012 Ford f150 3. 5 truck shifted all the way down to 1st gear which almost caused me to wreck on the highway and other cars to almost slam into me. Now when I try to drive the truck it keeps throwing a wrench and the wrench blinks and my truck will not shift hardly at all between the gears. After I have researched this issue I see that there has been 4 recalls and a few csp notices for the make and modle of my truck. The recall numbers are #19v075000, 12v190000, 16v248000, 12v198000 and the csp campaign number is #16n02 regarding the lead frame issue that causes the extreme downshift. I contact the Ford dealership to try and get this fixed and they said there is nothing they can do to help me.

The transmission would randomly shift into first regardless of speed. Several times this occurred at highway speeds causing a sudden decrease on speed nearly leading to a rear end collision. The problem worsened to the point it would suddenly hunt for a gear. Fortunately this did not occur on the highway as it probably would have led to a serious accident. The problem was confirmed and repaired by an independent shop by replacing the molded lead frame in the transmission. There was no warning when the dangerous condition would occur.

Nhtsa complaint statement (2018 Ford F-150, 10r80 transmission – cdf drum issue) I am filing this complaint regarding the automatic 10r80 transmission installed in my 2018 Ford F-150. This transmission suffers from a well-documented defect involving the cdf drum, which is a critical component for clutch engagement and shift control. The defect causes a variety of unsafe conditions, including erratic shifting, gear slippage, harsh engagement, hesitation on acceleration, surging between gears, and sudden or complete loss of drive power. These failures occur unpredictably, placing both the driver and others at risk. In my experience, and in the reports of many other owners, the transmission will sometimes delay engagement when pulling into traffic or attempting to merge, leaving the vehicle vulnerable to collision. At other times, the truck surges forward without smooth control when shifting, or drops into neutral-like conditions, preventing acceleration. This behavior is not only inconvenient but represents a serious safety hazard that could easily result in an accident at highway speeds or in intersections. Ford motor company has released multiple technical service bulletins related to the 10r80 transmission and its harsh shifting behavior, yet none provide a lasting repair for the cdf drum defect. In most cases, the only available remedy is costly transmission replacement or complete rebuild, often well before expected service life. This is clearly not normal wear-and-tear but a design or manufacturing flaw that compromises safe operation. Given the widespread reports, repeat failures, and the safety implications of a transmission that can suddenly fail, I respectfully request that NHTSA open an investigation into the Ford 10r80 transmission and specifically the cdf drum issue. A recall or mandated corrective action is necessary to protect vehicle owners and the public from the risks created by this defect.

Vehicle started getting stuck in different gears. Would drive fine for a little while and then get stuck causing you to pull over on going traffic. Having to sit for a while until it was ready to shift again. Would have to shift at manual at times to make it back home. You wouldn’t feel safe at times driving because you didn’t know what to expect anymore. Wrench light would come on and sometimes air bag light will come on as well.

Driving at highway speed the original transmission down shifted by it self at 70 m. P. H. The truck made a clunk and skid for a few seconds, then transmission fluid started spewing all over the place. Hade too take to dealer in mount vernon iowa they replaced transmission at 100,053 miles. Now the remanufactured transmission from Ford is doing the same thing with only around 2,000 miles on it. This time it happened I was scared that we were going to wreck. The truck actually bounced in the rear and skidded again. I think there should be something done before my self or someone else gets killed with this issue. As of now my truck is at the shop again for the transmission problem. Thanks [xxx] .

2012 Ford f150 transmission lead frame internal failure causing intermittent harsh shifting. Highway speeds and truck shifting into 2/3 gear and almost causing wreck. Took it into shop for repair and they said I had a recall. However inwas outside of recall period. Now I have to pay $2k to fix a for a known recall issue. Does should fix all vehicles with this known safety issue.

Transmission will not shift into gear. No recall on this and dealers option is for service and repair. Transmission was serviced and problem shifting still continues. I have received alerts from Ford pass app indicating powertrain malfunction/ reduced power — what is happening? the transmission control module has detected a concern when trying to shift to 7th gear. A failsafe logic disables 7th gear for the remainder of this key cycle. What should I do? have your vehicle checked by an authorized dealer as soon as possible. This loss of power is a huge safety issue as when I accelerate into traffic the lag in shifting causes the truck to not get up to speed and you’re basically a sitting duck. Transmission was serviced and this did not resolve the issues. Replacement is now scheduled and will cost a minimum of $9000. 00. This is a known issue with the 10-speed transmissions and should be recalled for repair &/or replacement by Ford. This truck has only 116,000 miles!!.

Lead frame malfunction vehicle downshifts into lower gears and won't shift afterwards have not taken to service center as of today just started happening recently no inspections have been performed a service warning came on after the sudden downshift.

Safety recall # 19s07 for my 07/12 2012 f150 followed by Ford customer service 19n01 vehicles with 6r80 transmissions molded lead frame replacement extends warranty coverage 10 years 150000 miles but does not cover the early vehicles that have the same problems my truck is 13 years old with 78000 mlies this is an extremely dangerous condition to down shift into low gear at hi way speeds.

Transmission has lots of issue, clunky shifting, surges, weird noises. Happens every time you drive. Dealer said it was normal but it's not. I've driven plenty of these 10r80s and they didn't have this issue. Engine makes noises that are not on other examples of this engine, my dad has the same truck and had similar issues and had to spend thousands of dollars to fix an engineering defect in the cam phasers. Dealer also said these noises were normal while under warranty - I see countless posts on forums saying the same thing then for others, after warranty suddenly its a problem because a retail job pays 30-40% more than a warranty job. Such a scam and you just keep allowing it. There is simply no reason that the 10r80 transmission and 3. 5 ecoboost gen 2 engines haven't been recalled yet. Ford has issued updated parts, admitted to engineering issues that caused these issues so why are customers forced to pay to fix engineered issues? they admited fault, they need to make it right for their customers instead of screwing us over.

My truck would shift gears randomly and the transmission would slip every time I start to accelerate. I took it to the shop and they said that there was internal cdg cylinder failure. I looked it up and it seems as that this has been an issue with a lot of F-150's.

10rd80 transmission cdf drum failure. A known design defect on 2020 f150 that Ford should issue a recall on. Ford finally fixed the design issue in August 2022. My truck is out of warranty so I will be out over $6000 that I do not have to fix. Extreme financial problem as I do not have the money to fix and this is my only vehicle.

Automatic transmission having major jerking and shuttering issues.

The contact owns a 2021 Ford F-150. The contact stated while driving 35 mph, the vehicle was shaking erratically. There were no warning lights illuminated. In addition, the gear shifter independently shifted into neutral. The vehicle was taken to the dealer where it was diagnosed with transmission failure. The contact was informed that the transmission needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure and a case was filed. The failure mileage was approximately 119,000.

The contact owns a 2014 Ford F-150. The contact received notification of NHTSA campaign number: 24v444000 (power train). The contact stated that while driving at 55 mph, the transmission unexpectedly downshifted independently. No warning lights were illuminated. The contact was able to coast to the side of the road. The contact shifted into park(p) and, while in idle, the contact waited for a short while before driving to the residence. While driving to the residence, the failure persisted. The transmission downshifted with an abnormal sound coming from the rear tires. The tires spun independently and left black marks on the street. The contact was able to drive to the residence. The vehicle was parked and no longer driven due to safety concerns. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was not notified of the failure. The failure mileage was approximately 214,000.

I was driving my 2015 Ford f150 and just pulled into the parking lot. The lights on the dash started going off (airbags, parking detectors, big wrench, etc), however the vehicle driving wasn't affected at that time. I immediately stopped and parked, when I returned to my vehicle it had full power, but wouldn't even attempt to start. I had no choice but to tow it to a nearby Ford dealership in grapevine, TX. It was ultimately diagnosed with a bad "transmission lead harness. " the dealership told me that this was a recall item on many f150s, but for some reason, not on mine. I researched this specific issue and found that 2011-2016 models of f150 were affected. It shows an investigation was opened for 2015 models as well. My question is why my specific vehicle is not under a recall. This could be a potentially dangerous issue, I'd think. So, right now I'm looking at a nearly $2000 bill to repair my vehicle when they get the parts in on Friday, 10/10/2025. I believe that if this is a recall on other with the same transmission lead harness, why is mine separated from that. I was given no warning other than the lights going off just before shutting of my truck, then it wouldn't start again. Thankfully I was in a populated area and not in the middle of nowhere. Please advise on any possible what I can get reimbursed for this issue.

Pulling onto [xxx] , with cars coming at me at 55 mph or more, the transmission slammed into gear and caused it to stall. Dealership diagnosed cdf failure and recommended replacement of the transmission. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Going down the highway at 60mph. Car went from 6th gear to 1st gear and tires locked up and I started sliding. I could smell the tires burning. I threw it into neutral and the tires unlocked. I dropped back down to 40 mph and went back into drive. No issue after.

Vehicle has just over 62,000 miles on it and is just out of warranty. On [xxx] I was driving home from colorado and the 10r80 transmission hesitated downshifting for a few seconds when climbing a hill and let out a very loud banging sound which shook the whole truck. Shortly after, the transmission tried to downshift and upshift on it's own repeatedly and would not transfer power at all. I quickly shifted it into neutral and pulled to the side of the road. This was really sudden and happened with no warning at full highway speeds(75 mph) on [xxx] southbound. If my wife would have been driving, I am not sure she would have been able to react as quickly. She wouldn't have realized what was happening. This could have easily resulted in a serious or life threatening accident. The leaking fluid also caused a sigificant amount of smoke on the underside of the vehicle as it dripped on the exhaust system. I quickly shut the vehicle off realizing it could catch on fire, but someone may not realize this as a possibility in the moment. I currently have the vehicle at a local transmission shop who has rebuilt several of these Ford 10r80 transmissions. His opinion, which will be verified by the teardown process as he rebuilds it, is that there are several common failure points which should have already been recalled by Ford in these transmissions. #1. The cdf drum which holds the clutch packs is machined in a way which allows the seal to slip and cause falure. #2. The valve body is know to wear prematurely which causes movement and leakage contributing to failure. #3. The high pressure pump is also a known failure point which can cause downstream shift issues and failure. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Ford has released multiple tsbs related to a known design flaw with their 10r80 transmission that causes the transmission to experience hard shifts while moving and often occurs in traffic. The hard shifts can cause the vehicle to stall which creates a very unsafe situation, especially on highways and interstates. The transmission defect has been redesigned in newer vehicles, however, there are thousands if not hundred of thousands of these vehicles on roadways that can break down suddenly causing a major accident. The Ford owners forums have been riddle with concerns about this issue related to the cdf drum in the 10r80 transmission.

10-11-25 transmission changed on its own from 6 gear going 63mph to first or second gear to 13mph (what I seen after realizing what happened) I already had it into Ford for sensor warnings before this and they couldn't find the problem. Now work is done and first gear is rough, and it still acts up towing a trailer. I take it back in on the 20th because I was not offered a rent a car or loaner and they think it's a clutch problem now. Ford will not help with repairs or take blame that this could have been a very bad situation if a semi was behind me. This is a known issue for 2015-2017 models.

The contact owns a 2017 Ford F-150. The contact stated that after cold starting the vehicle, the transmission hesitated and then shifted into the next gear with a bump. The contact stated that once the engine had warmed up, the transmission shifted normally. The contact stated that recently, while stopped at a traffic light, after the light changed, the accelerator pedal was depressed; however, the vehicle failed to move. The contact stated that the engine was running, but the vehicle failed to respond. The contact shifted manually to first gear, and the vehicle moved forward with a bump. The contact stated that there were no warning lights illuminated. The contact had not yet taken the vehicle to a dealer or independent mechanic. The vehicle was not diagnosed or repaired. The contact stated that the transmission and engine were replaced several years ago. The manufacturer was not informed of the failure. The failure mileage was 86,530.

Shortly after I purchased my 2018 f150 in April of 2018 I brought it back to my dealer in June stating that it was shifting hard in and out of 5th gear. My service advisor at that time said his f150 was doing the same thing. They plugged it into their computer and stated that there was no problem. Subsequent trips back for the same problem resulted in the same answers. Now in September of 2025 on the 26th, with 56k miles on the truck the transmission is lunging so hard at stops that it feels like I was hit from behind.

I have had several incidences of the transmission suddenly downshifting with corresponding loss of some gauges. This is similar to the 2019 recall NHTSA no. 19v-075. I had that service done in July 2019 before any symptom surfaced. Now, in 2025 the problem has started again. I'm not sure what the previous service included (I. E. Partes replaced) the original recall indicated the transmission molded leadframe however I have no documentation that it was replaced. It appears that only a reprogramming was accomplished.

I had an issue with the transmission lead frame where my vehicle downshifted from 5th to 1st gear which to me is a safety issue. Notified Ford and they said this was a customer satisfaction program that expires after 10 years. How is this not a safety recall?? this could be very dangerous if you were on the interstate and you’re going 70 mph, please help.

This truck has been in the shop 4 different times due to the transmission shifting erratically, jumping between gears, loss of power, and hard shifting. Ford knows this is a problem with the 10r80 transmission, you know this is a problem with the 10r80 transmission. Yesterday while driving 55mph the truck shifted itself into 1st gear, the truck momentarily jerked, the rpm’s shot up to 5000 and then the truck just lost all power like it was in neutral and wouldn’t move. After almost getting hit by the car behind me and the car coming at me, I drifted off the road and it took ten minutes before it would go into gear correctly, at which time I drove it slowly home with the flashers on. Now I have to take it back to the shop for the 5th time for this same dangerous problem. I am aware as I know that you are too of the numerous class action lawsuits around the country against Ford for this issue with millions of vehicles. Yet you sit on your hands not ordering Ford to issue a recall. Do your job!.

The contact owns a 2013 Ford F-150. The contact stated that while driving 20-30 mph, the transmission unexpectedly downshifted to first gear. The check engine warning light was illuminated. The contact pulled over to the side of the road and shifted to neutral(n). The contact turned off and restarted the vehicle, and the contact noticed that the speedometer was inoperable. The contact stated that the vehicle was significantly sluggish while driving from a complete stop, and the tachometer failed to exceed 2,000 rpm while driving. The contact activated the hazard lights and was able to drive to the residence. The contact scanned the vehicle with a scanner and retrieved diagnostic trouble codes indicating an output shaft speed sensor failure. The contact became aware that the VIN was included in NHTSA campaign number: 19v075000 (power train), and the vehicle was taken to the dealer for the recall repair; however, the dealer informed the contact that the vehicle was not covered and provided an estimate for the repair. The vehicle was not repaired. The manufacturer was contacted and advised that the contact to pay for the repair and might be reimbursed at a later date. The failure mileage was approximately 228,000.
