Transmission will change gears while driving. I can be driving 45 mph in traffic, truck will automatically shift and I'm now going 15 and cannot speed up. There is no warning lites on dash before issue occurs. Called dealership who had no solutions to offer. I cannot be the only one experiencing this issue from reading online forums and Ford needs to be held accountable for faulty equipment. This is a safety issue in traffic for my family.
We purchased this vehicle approximately 6 months ago. On our second long trip of owning it we noticed that when we would give it gas to pass vehicles it would down shift and up shift hard. No warning/error lights came on. We dud have a diagnostic check done but nothing came up. The mechanic at Nicely's said it could be the clutch bank? I read where these similar trucks are having the same issues with shifting and there are some recalls on them. Please help..my warranty was only good for 6 months therefore expired. Where and how to we go from here.
While driving vehicle at 60 mph transmission shifted unexpectedly to a lower gear increasing the rpm’s on engine. Vehicle transmission would not operate normally after this incident. The orange colored warning “ wrench” symbol instantly came on after this incident. I drove truck to a Ford Dealership that was close by and they replaced the lead frame component on the truck . See attachment for details of repair . This appears to have corrected the issue with the transmission.
My transmission is shifting gears on its own. Sometimes it will downshift and other times it will shift up. Ford denies this problem and wants to replace it for $8000.
The contact owns a 2017 Ford F-150. The contact stated that while driving 65 MPH and accelerating to overtake another vehicle, the transmission unexpectedly downshifted, and the vehicle jerked hard and then shut off. The contact was able to coast to the side of the road, shift to park, and restart the vehicle. While driving 35 MPH, the rear wheels locked up momentarily and then continued moving. There were no warning lights illuminated. The vehicle was taken to a local dealer, who was unable to determine the cause of the failure. The vehicle was not diagnosed or repaired. The contact called an independent mechanic to schedule an appointment. The manufacturer was not contacted. The failure mileage was approximately 72,000. The VIN was not available.
1.) transmission downshifting slamming hard into 1st randomly while driving on freeway. 2.) transmission stuttering in 2nd, 3rd & 4th gear. 3.) wouldn't shift until into the high RPM's at normal acceleration. 4.) has put me at risk multiple times almost causing wreck to other drivers. 5.) service engine light randomly coming on and off 6.) had a 3rd party overhaul the transmission & torque converter back in april 3, 2024.
Transmission will randomly downshift several gears, causing a major safety issue.
After the 2nd year of owning the truck the transmission blew up. I paid out of pocket to replace the transmission in full & then now 4 years later the transmission blew up again. Timing chain is also broken & engine is failing. 2017 FordF150 Lariat Sport.
The truck will spontaneously downshift when driving. This creates a intense bang and vibration in the vehicle with an instantaneous speed change of vehicle. It's quite scary when it happens. I don't believe that it's any good for the drive shaft or rear end with such a sudden instantaneous transmission shift. I fear for additional damage it to the vehicle and the existing drivetrain when this occurs and could cause an accident if someone is following too close to the back of me when this happens.
I have had transmission gear changes abruptly/rough on my 6 speed 2017 XLT F150. It seems to happen more often downshifting from 4th to 3rd gear. I reported this to dealer early after purchase when I still had factory waranty. Dealer inspected and answered that “this is normal.”
Loss of gear at highway speeds. Went from 10th gear to 1st. Tires locked up and an error for the drive train showed up on the dash. Pulled over, restarted vehicle and it seemed to work. This has happened 3 times since. I was luck that no vehicles were around me or I would have caused an accident and potentially chasing injury to myself, my family or another driver. Dealership was not able to locate issue. Told me to keep driving and report back when it happens again.
My transmission automatically downshifts sometimes which could cause me to lose control and is a big safety hazard.
The contact owns a 2017 Ford F-150. The contact stated that while driving with the cruise control activated and set to 77 MPH, the transmission unexpectedly downshifted to first gear, causing the vehicle to jerk violently. The vehicle made an abnormal whistling sound, with the RPM revving high. The vehicle was taken to the dealer; however, the contact was informed that no cause of transmission failure was found. The vehicle was not repaired and remained at the dealer. The contact related the failure to the federal safety agency Campaign Number: 19V075000 (Power Train); however, the VIN was not included in the recall. The manufacturer was made aware of the failure and advised the contact to file a complaint with the federal safety agency Hotline. The failure mileage was approximately 172,000.
After I purchased a RV and making the trip home, we went through several stop lights. As we were slowing down to make a stop at light, the vehicle made an abrupt downshift. Seemed like it was in fourth gear and went in to first or second gear. The vehicle jerked and the rpm went to around 6000. I thought my engine was going to blow up!! Scary and felt dangerous! Then it happened again approximately 10 miles down the road. I haven't experienced this since this date but I haven't pulled anything since then either. Please make this a recall. It isn't just the 2014 model. I have V8 5.0 6 speed transmission. Please help.
My truck randomly shifted from 4th to 1st while I was traveling down [XXX] heading south from union city Indiana. Lucky they wasn’t another car near at the time and I was able to keep it on the road avoiding an accident. But now my truck is acting funny and I’m worried it’s gonna do it again and hurt me or somebody else. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
The contact owns a 2017 Ford F-150. While the contact's son was driving 70 MPH, the transmission independently downshifted with several unknown warning lights illuminated. The contact stated that the rear wheels locked up and the vehicle skidded. The vehicle was taken to a nearby Dodge dealer and the computer was reset; however, the failure reoccurred 50 miles later. The vehicle was taken to an independent mechanic where it was diagnosed with electrical components failure inside the transmission, and there were metal shavings inside the oil pan. The contact was informed that the transmission fluid, filter, and electrical components in the transmission needed to be replaced. The dealer was made aware of the failure. The vehicle was repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 115,000.
The vehicle’s rear wheels temporarily locked up when coming to a stop. Fortunately it was only under 30mph. Vehicle later got stuck in 3rd gear driving in town, check engine light did come on with DTC p0717. It is the same issue that 2014 F150 with the 6r80 transmissions are having.
Truck began downshifting from 6th gear to 5th numerous times at highway speeds (60ish mph). Wrench warning light would randomly come on, Service Engine Soon light would intermittently come on, followed by the dashboard totally blanking out. In one day on a drive to work, it started shifting from 6th to 4th. On the way home the same day, it shifted violently from 6th to 2nd gear hard at highway speed. The occurrence was a big safety concern as it was raining out - almost skidded out of control. As the truck was being driven into the dealership, there was NO acceleration - just revving of the engine which could have caused a major accident while having to cross two lanes of oncoming traffic. They diagnosed it as follows: 108572 found DTCP0706, P0707, P1702 / 20107 CF / MB3Z*7A100*B Transmission Control Assembly / FL3Z*7A098*B Screen Assembly / 7-XT*10QLVC Auto Transmission Oil. Dealership said that it was "normal wear and tear" and the repair bill was $2,436. Since repair, the truck has been operating without issue.
The contact owns a 2017 Ford F-150. The contact stated while driving at various speeds, the transmission struggled to shift as needed. Additionally, occasionally the vehicle jolted upon shifting into a lower or higher gear. There was no warning light illuminated. The vehicle was taken to a local dealer where the vehicle was diagnosed, and the contact was informed that the transmission was faulty and needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 38,000.
When using the cruise control and going down hills, the transmission will unexpectedly downshift into one or more lower gears causing the rear wheels to chirp or actually slide on wet pavement. it only seems to happen when using the cruise control for some reason.
The contact owns a 2017 Ford F-150. The contact stated that while driving approximately 55-60 MPH, the transmission unexpectedly downshifted to first gear, causing the rear wheels to lock up. The check engine warning light was illuminated, and the wrench symbol was displayed on the instrument panel. The vehicle went into LIMP Mode, and the vehicle was slow to respond. The vehicle was turned off for ten minutes and then restarted. While driving approximately 25-30 MPH, the failure recurred. The contact stated that DTC: P1702; indicated an intermittent failure with the transmission range sensor circuit (PRNDL sensor), potentially causing erratic shifting or even the vehicle entering LIMP Mode. The local dealer was contacted, but the vehicle was not diagnosed or repaired. The manufacturer was contacted and opened a case, and referred the contact to the federal safety agency Hotline for assistance. The failure mileage was approximately 108,700.
Vehicle unexpectedly downshifted and service now light came on. Speed was difficult to control as the vehicle would either rapidly decelerate or accelerate. Cruise control was unable to be used. I received a speeding ticket because I was unable to consistently maintain speed. Problem returns intermittently and is usually resolved by pulling over, turning off the vehicle and turning back on.
I was experiencing hard shifting in upper gears like 8, 9 and 10. At 118592 miles the Ford dealer told me the transmission needed to be replaced. I had them install a Ford remanufactured transmission. The dealer told me this reman should have all the upgrades of the latest transmissions. Reman number is JL3Z 7000L. At around 123000 miles I experienced the following. I had the cruise control set at 74mph. On an upgrade I felt a hard shift. I noted the transmission was in 8th gear. Then it shifted to 9th, 10th and then to 1st. The truck was suddenly slowing down for what seemed like 3 to 5 seconds before shifting into 10th. I did not hit the brakes. Cruise control was still engaged. Suddenly it repeated the shifting from 10 to 9 to 8 to 9 to 10 to 1st and then 10th. The wrench warning turn on and 10th gear was locked out. After cycling the engine off and on again I have not experienced this again. I did notice after the incident my vehicle had an oily residue on the exterior. I was traveling on a dry road with few cars around me and good tires. I did not consider it a safety concern until I read about the 6 speed transmissions experiencing this and the their safety concerns. What if someone had been behind me, what if the road had been slick, what if my tires had not been in good condition? I searched ford forums online and was surprised to find others as recently 2023 have reported exactly the same experience on 2018 F150. The fact that my transmission is supposedly what is in the 2025 concerns me. I waiting to get my truck back into Ford Service.
Truck is dropping gears/drop into neutral/reverse/park while driving. Problem initially began only within the instrument cluster, but as time went on it progressed to dropping gears with erratic gear indication on the instrument cluster (flickering through P N D R M 1 2). A video can be provided upon request, but cannot be attached to this inquiry. Once the truck was taken into the shop I was made aware of other F150s of the same year/model having the same issue, and that Ford is currently investigating. The technician at the Ford dealership correlated the issue to the lead frame harnesses part.
While doing approximately 65 MPH on highway the transmission was in it’s highest gear, 10th on the automatic transmission. It suddenly down shifted to 4th gear uncommandedly .
While traveling at approximately 75 MPH, the transmission downshifted one(1) speed for about 5 seconds, then upshifted back into high Gear. I briefly got a readout that said "seeking parameters." This is a 10 speed transmission, my assessment is that what it did was drop from the "overdrive" gear into 9th gear. It was a single incident and did not create a safety hazard but may be a precursor for future problems. The vehicle has roughly 65000 miles on it.
This issue has happened multiple times. While driving at highway speeds, the truck downshifts too many gears and causes the back tires to almost skid, causing all the passengers in the vehicle to slam forward. When this happens, it doesn't matter if you try to accelerate, manually shift gears, put it in tow mode, nothing works. Then all of the sudden, it will shift back into a higher gear and let you accelerate again. It started a couple of years ago, but at the time Ford was just now addressing the issue with vehicles under warranty and recalled them. Ford was stating that it was a software issue, but after a few months, people that got the new software stated that the issue came back. March of 2024, Ford released a TSB on how to fix the issue, but refuses to admit that it is a safety issue and recall it. My truck was dropped off this morning at the Ford Dealership. I am hoping that the TSB is a permanent fix. IT wasn't until I got to work that I saw the news that Ford is finally being investigated for this as a safety issue. Hopefully it turns into a recall and I can get reimbursed.
My 2017 2.7l 6 speed f150 frequently experiences a random downshift to 1gear at various speeds and then it shifts to 5th gear and then 4th gear and then it stays in 4th gear. Multiple transmission shops have noted that the lead frame and valve body are potentially responsible for the downshift because the previous generation 6 speeds had the same issue. No codes are populating when the downshift happens and no CEL or Wrench light come onto the screen. The only way to get the truck to shift properly again is to turn it off and wait a while and then turn it back on. This problem has been reproduced by independent service centers.
transmission suddenly downshifted while driving down highway, end result several components in the transmission, lead frame, valve body, torque converter clutch were replaced at my own expense of $3300
