The contact owns a 2016 Ford F-150. The contact stated that while driving approximately 45 MPH and descending a hill, the brake pedal was depressed, and the transmission unexpectedly downshifted into a lower gear. No warning light was illuminated. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 30,000.
I was traveling down the road at about 45 mph when the vehicle suddenly fell out of gear and the rear wheel locked up for a second. Then the truck would not go above 30mph. I had to have it towed to the dealer and was told the lead frame sensor failed. Had to pay for repairs. Should be part of your current investigation
On my way home from a trip on Tuesday 4-14-26 at about 60 mph with cruise control on the truck downshifted and turned cruise control off and a small wrench came on display. I made my way to next town at reduced speed, wouldn't get out of 5th gear, found a ford dealer had them scan and check out. They found 2 codes P061B:00-24- pcm and P0722:00-68 They cleared codes and drove truck with no return of trouble. I resumed my trip home and same thing happened about 1 hour later, stopped for fuel, and returned to the road with no problem or wrench on display. Came home went to my local transmission shop and he informed me that this was a known problem and warranty has been extended to 10years or 150k miles. Went to my local Ford dealer and they didn't know anything about extended warranty coverage
transmission not shifting properly and shutting down not able to drive,hard shifting from 3rd to 4th, it iS A 6 speed V8
When I come to a stop at a stop sign or waiting for traffic to pass to make a turn, and try to accelerate, my truck does not accelerate as usual. On the dash it shows that the gear shifts into 5th, from the get go, after having been at a full stop. At some point it then down shifts from 5th to 2nd. A wrench appears on my dash as well. A very loud fan noise also came from my engine area. This was highly dangerous, because as i was trying to turn left on a fast paced road, my truck could not / would not accelerate as normal and i was kind of stuck sideways on a two lane road. The same happened when i tried to turn off the road. I was making a left turn. Unfortunately i had to come to a full stop to let the other cars pass, so i could make my left. Once i tried to accelerate to make my left hand turn, it took quite a while for me to make the turn and i was kind of stuck sideways on the road. The gears were not shifting properly throughout my drive from my house to my destination and back. I stopped using it once i got back to my house.
In 1 week 2 unexpected shifts into neutral occurred. On the third occurrence the wrench light came on and the vehicle would not shift out of third gear. I pulled code P1702. I will be replacing the transmission molded lead frame this weekend. It is not safe to drive.
Truck shifts down without warning causing the truck to skid and squeal tires. This could cause a crash is definitely causes damage to the transmission.
The Transmission Started suddenly, downshifting from high gear to a lower gear at speed, non-sequential and unexpected. I.e., not regular accelerations shifting from 6th to 5th, but a hard, sudden, unexpected shift from 5th to 1st. causing jerking and high rpms. Subsequently, it has not downshifted and has remained stuck in a higher gear at a complete stop, like at a traffic light in 5th or 6th gear, increasing the risk of being unable to accelerate from a stop if needed.
While driving at steady speeds around 50–65 mph, the vehicle intermittently feels like it shifts into neutral and the engine revs unexpectedly. After a moment, the transmission re-engages. This creates a safety concern, especially at highway speeds. Issue appears consistent with reported problems involving OSS (Output Shaft Speed) sensor or transmission lead frame signal loss in 2015–2017 Ford F-150 vehicles currently under the federal safety agency investigation.
Saturday 4/4 I took the truck to get a tire repaired. It would not initially start. 5 minutes later it finally did. Then a few blocks away the trucks internal lights started flashing and it jumped from drive into a lower gear. I thought my drive quit working. I pulled over and had reverse and low so I attempted to put in drive, still wouldn't go. After about 5 minutes I was able to get the truck back into drive and get it home where it sits today. I just bought it 1 1/2 months ago. It happened to my son also on Thursday 4/2 but I just found out about it. He was going highway speeds when lights started flashing and truck jerked from drive into a lower gear. THIS SHOULD BE A RECALL. THIS IS VERY DANGEROUS. I want to know what you are going to do about it? I just paid $22,000 for this truck. I shouldn't have to deal with this. My son looked it up and says it is P0707 lead frame failure or output shaft speed sensor. Whatever the case, it would be nice to know what can be done about it other than switching to manual dirive.
Faulty trans conductor plate Trans slipping on the 2-3 and 3-4 shifts from the speed sensor issue that damaged the trans. Need rebuilt or replaced.
While driving at highway speed, in traffic, the transmission down-shifted without warning almost causing me to lose control and almost rear ended by another vehicle. The vehicle then lost power and would barely make it uphill. After parking safely and shutting it off, the check engine light came on and it would not crank and would not show what gear it was in. According to the Ford dealer, where I had it towed for repair, it suffered a lead frame failure and pcm failure and cost over $2300.00 to repair plus a $240.00 tow bill.
There currently is a the federal safety agency inspection investigation going for this issue. I only have 75k miles on this truck. The shifting is off. Sometimes it goes out of gear. I had to stop and restart everything to get it home. Getting on the freeway it went to first gear and I had to pull over. Made a weird noise in shifting. The shift illumination goes on and off. The shifting was acting definitely not right.
The truck out of nowhere downshifted when I was going down the highway at 60 and locked up the back tires, and then it went into limp mode and woundnt drive very fast. The mechanic shop said that it was probably that the TRS and the 6R80 transmission were currently being investigated for these safety concerns and i couldnt agree more. I could have hit someone or even got hurt my self.
I've been reading the reports that there could be a recall for transmission issues in 2016 F150's. I've noticed similar issues as what's been reported. This is irregular shifting, down shifting hard at times, and irregular shifting in cruise control.
I have noticed transmission slipping when transitioning from 3rd gear to 4th. It has done this is owning the truck. There is also a noticeable lagging when accelerating.
Sudden downshift when going down a long hill while driving at highway speeds then applying brakes to slow down. Luckily no one was behind me because its like slamming on the brakes with no brake lights. I could have easily been rear ended or gone into oncoming traffic if it I was on wet snowy or icy roads. It's happened more than one time. Something needs to be done before someone is killed!
While driving, the hill descent fault error would pop up on the instrument panel, the truck would begin to shake, and the gas pedal would no longer work. I would have to pull over, shut the vehicle off for a few minutes and restart it. This happened multiple time while driving on the highway and in town. After sitting in the driveway for while trying to get repairs scheduled, the issue got worse, and I would have to pull over every one to 2 minutes due to this issue occuring.
Within the past year there have been a few times when driving in 6th gear (primarily, but also happens in 5th) if I press the gas and it downshifts into 5th, it will trip a gear icon warning light, either not shift, shift into 4th, 3rd, or neutral and sometimes VERY abruptly. When that happens, I've managed to get to the side of the road, turn the truck off and back on, then everything is good for a while. It happens randomly in different conditions and can occur and hour later, a couple of days or as long as a few months. I scanned the system and it showed a P0735 : 00-6C error. When this happens the dash usually does not show the correct gear the truck is in.
Date of occurrence 3-11-2026 2016 F-150 5.0 6R80- Vehicle down shifted to first gear sporadically locking rear wheels up around 30-35 mph. Wrench light came on saying see manual. Shortly after the check engine light came on. I came to a stop and the truck wouldn’t shift properly. When I would put it in reverse it would slam into gear. The dash would not show if I was in park, drive or reverse. I shut the vehicle off and it would not restart or turn over. I was only a mile or two from home. Was able to get it home in neutral with the truck off with a short tow. The truck started fine and acted fine the following day. I thought it was just a glitch so I drove it around in the driveway. And once the truck and trans got up to full operation temps the same problem occurred. Thankfully it was still in the driveway so that’s where it sits now. It is very unsafe and unstable to drive. 130,000 miles. I was able to hook my code reader up to it and now I’m getting codes P0707/P0706 all Transmission range sensor codes. P0707(1/ 6) Stored Transmission Range Sensor 'A' Circuit Low DTC Severity 2 of 3: This fault may pose damage to components and should be repaired as soon as possible.//// P0706(2/6) Stored Transmission Range Sensor 'A' Circuit Range/Performance/// P0707(4/6) Pending Transmission Range Sensor 'A' Circuit Low The vehicle is still at my residence I have not moved it since the occurrence. Has not been inspected by dealer or mechanic. Will have to arrange a flatbed tow to a facility so there is no risk of injury or causing any more possible damage if any exists.
Transmission jumping through gears and lost ability to shift shortly after the jumping of gears. it jumps straight in to 5th gear when put in to Drive
My Ford F150 randomly won't start.It also randomly down shifts while driving.There have been times I've been driving 50mph and the transmission starts down shifting on its own.
Today I was driving my truck at 55mph on a local highway and all of the sudden I felt/heard/experienced a massive clunk out of nowhere - almost like the truck tried to downshift into 1st or something similarly jarring. It only lasted a second, and then I got a dash light on that said Service AdvanceTrac. Based on the service codes I'm seeing (two of them that are both UO100 codes which indicate loss of communication), I did some research and found out about the OSS sensor issue and think that's what is going on with my truck too. Unfortunately I'm not sure if I'm going to be able to get a Ford dealership to do anything about it since there isn't an official recall, and I'm afraid to keep driving it as this is likely going to keep happening - but fixing it myself is going to be expensive I think. It is available for inspection upon request. I felt that my safety was and continues to be at risk - downshifting into 1st gear, or whatever that was, while driving high speeds is dangerous and could potentially significantly damage my vehicle and myself. I have not taken it anywhere yet to be reproduced or confirmed - just plugged my scanner in and did a bit of research. No one has inspected it.
I’m reporting a serious transmission issue with my 2016 F-150. While driving, the 'wrench' light suddenly pops up on my dash and the truck starts shifting erratically. Sometimes it feels like it’s searching for a gear or jerking unexpectedly. I had the codes scanned and found P0706, P0707, and P1921. These are all related to the Transmission Range Sensor (TRS) signal. I know the federal safety agency is currently investigating this exact failure under EA26001 because it causes the truck to lose track of what gear it’s in. Even though my tires haven't locked up yet, the erratic shifting is making the truck unpredictable and dangerous to drive in traffic. It’s clearly the same Lead Frame defect that is being investigated for a recall.
Driving and randomly truck gets confused on what gear its in, wrench light goes on and codes read transmission speed range sensor.
While traveling at interstate speed (75 mph) the transmission downshifted to 1st gear. truck slowed down ad engine revved up. i was able to get to the shoulder and stop. I attempted to take off again and the truck would on up shift to 5th gear and displayed the wrench icon on the instrument cluster. Had truck towed home, about 90 miles. Was advised that the problem was the molded lead frame in the transmission.
Transmission conductor plate (lead frame) failed and had to be replaced this week. Vehicle has only 54,000 miles on it. Total cost to repair was $1,167..
My truck is equipped with a 6R 80 transmission and as I was pulling off an offramp onto interstate 295 my transmission shifted into first gear and my truck skidded and came to a stop sideways with oncoming, traffic, barely avoiding me. The rear end of my truck literally locked up.
I know there is an ongoing investigation for F150s years 2015 to 2017 with the six speed automatic transmission. I just wanted to report that I've been having similar issues with my transmission, especially when 4 x 4 is enabled, it seems to worsen the problem. I've had unusual and unexpected shifting shifting. It's almost as if the gears are hiccoughing. I do remember they were having one issue on the highway upon accelerating where it dropped a few years, almost lags, but then came back. Like I said, it worsens in 4 x 4 and especially during hard accelerations, that is worth, I would emphasize the most. My biggest issue is upon hard accelerating. The gears slam, is the best way I could describe it. It's a noticeable and loud, slamming noise that happens when the gearshift from 1st to 2nd into third I haven't tried pushing it past fourth on hard acceleration I'll usually let off because it's such a loud slam, and noticeably shakes the vehicle.
