2015 Ford F-150 transmission problems

POWER TRAIN

While driving on the [XXX], close to [XXX], throttle response was lost on the vehicle. Immediately put the hazards on, turned them off momentarily to indicate a turn off to the shoulder, traffic was right behind me, with some fast movers. “Hill start assist not available” was displayed on the main panel and “trac off”/ traction control. Below approx 10 mph the vehicle started shaking violently and we came to a stop. Turned the vehicle off and started looking in the manual and online for associated issues. Was able to restart the vehicle with no annunciated issues and continued driving at a cautious speed. A few minutes later the same issue arose. Had to pull over and reset the vehicle. By this time we had committed to taking the vehicle to the Ford service center on the interstate and made it there after occurring 4-5 more times where we had to pull over during the worst time of day, avoiding traffic on the on/off ramps. We had to use heavy braking once as we were disabled and there was another disabled vehicle also pulled over and we had to stop before them with enough safety clearance. We made it to Ford. According to SB 16B32B, our truck qualifies for an expired recall based on the [XXX] plant and the production date. Ford produced P2112 code for throttle body issues. We paid for the repairs.

My 2015 Ford F-150 experienced multiple sudden downshifts at highway speeds 75 mph and then started downshifting at lower speeds. Heavy clunking heard and wrench warning lamp came on with a very general warning message and turned both off after moving to the side of the highway and restarting the car. Warning sign returned while driving at significantly lower speeds on city streets, locked up tires when turning from a low speed twice. Extremely unsafe and could have caused a serious accident if people were following close behind me. Took it to the dealership to get repaired and they diagnosed DTC P0722 (Output Shaft Speed Sensor - No Signal) and confirmed that the signal failure caused the transmission to lock in 3rd gear and operate at maximum line pressure. Technician notes it resulted in damage to forward, direct, and overdrive clutches and recommended the replacement of the entire transmission ($5,739 for parts). I paid $8,636.93 out-of-pocket at a Ford dealership for this service repair.

I was driving my f150 and all of a sudden it downshifted with a bang into 5th gear. I slowed down and noticed my transmission wouldn't downshift into any other gear. I had to stop truck with it stuck in 5th gear and transmission cooling fan sounded like a turbo fan. There was a wrench light that displayed and when I checked the codes it came up with P0720/P0721/P0722. All pointed to transmission issue. Shortly after they came out with the safety recall and after the "fix" my truck thru P0722 code again. Then the customer satisfaction program sent out letter said they would replace the lead frame at no cost even if you had over 150k. I paid over $400 dollars and multiple trips to dealer, and they stated that the truck didn't display Fords specific DTC Codes. My codes were identical to recall in 2014, and deadbeat ford won't replace my lead frame even though it's the same issue since 2011. When will the NHTSA step in an require ford to fix a well-known issue with this transmission?

I own a 2015 Ford F-150 equipped with the 6R80 transmission. I have experienced multiple intermittent transmission problems that I believe may present a safety concern. During one freeway incident, the wrench warning light came on and the transmission went into what appeared to be failsafe/limp mode. The truck would not accelerate normally and I was unable to get the vehicle much above approximately 50 mph. I pulled over, shut the engine off, and restarted it. After restarting, the transmission operated normally again. On multiple other occasions , I had separate incidents where the transmission became stuck in a gear while I was slowing to a stop at a traffic light. When I attempted to accelerate, the engine RPM became very high but the vehicle had very little acceleration. The transmission eventually began operating normally again, but then shifted very harshly into the correct gear. The vehicle currently has DTC P0717, Turbine Shaft Speed Sensor A — No Signal. I am attaching a Ford dealer service record. The service advisor’s written description states that the truck “down shifted to 1st” and was “stck in gear.” I want to clarify that these are the service advisor’s words summarizing my report, I did not tell the advisor that I observed the transmission downshift to first gear. I explained the incident on the freeway, only later learning this was likely the transmission going into failsafe, the wrench light came on, and the truck lost normal acceleration. The same dealer record recommends replacement of the transmission molded leadframe/filter. I am concerned that an intermittent failure involving the 6R80 transmission’s sensor/leadframe system could cause unexpected transmission behavior or loss of normal acceleration while driving, creating a safety hazard.

In September 2025 my 2015 F-150 did a hard downshift at speed. I took it in and they replaced the transmission lead frame, charging me $2,500. Since that time it has shifted hard from 1st to 2nd and 5th to 6th. In July, 2026, I received Ford Safety Recall 26S28, addressing the exact downshifting defect I paid to fix. I brought the truck in for the prescribed software remedy, in August, 2026 but the harsh shifting remained so i took it back on September 3rd, 2026 at which time they replace the valve body or lead frame and road tested it; the hard 1st to 2nd and 5th to 6th remained and the told me the transmission is "broke" and would require the entire transmission be replaced for ~$8,400. I reported this to Ford Motor Company Customer Satisfaction and it was escalated, case # CXH-09263554-W5R5T3, but was just told that "...there are no programs available to provide assistance with the repairs."

This is a supplemental complaint to my earlier report regarding NHTSA Campaign 26V237 / Ford Safety Recall 26S28. The recall remedy (PCM software update) was performed at W.C. Sanderson Ford in Healdsburg, CA on XXX. The original downshift defect recurred within weeks, including a near-miss where I nearly lost control of the vehicle with my [XXX] son inside. Since then, I have had the vehicle independently scanned twice, including a full all-systems diagnostic scan. The scan shows a communication fault (U0401, "Invalid Data Received From PCM") present across five separate control modules: ABS, Airbag/Occupant Classification System, Power Steering Control Module, Tire Pressure Monitoring/Body Control, and the engine module. The scan's own assessment recommends repairing CAN-BUS wiring and connections. I believe this network-wide wiring fault may be the actual underlying cause of the condition recall 26S28 was intended to fix — the recall's software update assumes a signal-loss problem can be resolved in software, but if the root cause is physical wiring, the remedy would not correct it. This would explain why the defect recurred so soon after the software update was installed. A second code, P2112 (Throttle Actuator Stuck Closed), also appeared spontaneously while the vehicle was parked. This code is documented in Ford's own Technical Service Bulletin 16-0139 (issued 2018), indicating Ford had prior knowledge of related fault patterns on this vehicle range. Of particular concern, the Airbag/Occupant Classification System is affected by the same communication fault. This system governs airbag deployment behavior based on occupant detection, and my son rides in this vehicle regularly. The vehicle is currently not safe to drive. I am requesting NHTSA evaluate whether the 26S28 remedy adequately addresses the underlying defect, given evidence that a wiring-level fault — not solely a software issue — may be the true root cause.

I was driving on a 2 lane highway at approximately 50 mph and my truck started blowing white smoke and suddenly decelerated to 5 mph and a wrench appeared on my dashboard. I luckily was able to limp the vehicle to a parking lot. I then called AAA for a tow to my Certified Mechanic. He informed me the next day that the transmission line to the cooler failed. He replaced the cooler lines ($250). I definitely feel this problem should have a safety recall issued. If my wife and I were on a freeway when this happened- the outcome could have been a lot worse. SAFETY SHOULD BE PARAMOUNT FOR ME AND THE DRIVERS BEHIND ME!

I had Ford Safety Recall 26S28 performed on my 2015 F-150 for the unintended transmission downshift issue. Since the recall, my truck has experienced multiple unintended downshift events. Today, this happened twice — the second time I nearly lost control of the vehicle and almost had an accident. My [XXX] son rides in this vehicle frequently, including on many of the trips where this defect has occurred. I have had the vehicle scanned twice since the recall service. Both scans showed stored codes U0401-02 and U0401-00 (PCM communication failure) and U3013-16 (control module input power circuit fault) — all in the same system the recall software update was designed to address. The dealership that performed the recall, W.C. Sanderson Ford in Healdsburg, CA, has refused to diagnose the vehicle without an upfront fee I cannot afford. Ford Customer Relationship Center has also declined to assist.

After receiving Recall#26S28/NHTSA Rcall#26V237, I made appointment for the transmission module remedy upgrade.After getting upgrade, I didn't go a mile when it stuck in 3rd gear and wrench light came on..I took truck back to Ford garage and had to leave it there.A few days later I picked truck up and made it about 5 miles.I took it back ,as they wanted to drive it and try to get correct codes to come up, but all it did was keep coming up as a different code that wasn't warranted...We had a rejection from Ford on a conference call between Ford,Ford garage, and myself...they would only replace "lead frame"if the down shifting code came up...well, they already upgraded that but will not replace "lead frame" that shows a bad realy molded on it...I have truck back after 2 weeks sitting at their shop, but cannot drive it .When I take off from a stop it will do a hard shift into 3rd, wrench light and tranny fan comes on and I have to find a spot to pull over as it will not shift higher.Once shut off, I can restart and continue, but it usually does it several times before I can continue and shifting returns to normal...Recall from Ford shows if software upgrade doesn't rectify problem, they will replace "lead frame"- Ford garage wants me to drive it until code comes up that they need to warranty "lead frame", but its not safe to drive as it now has up-shifting problem.

POWER TRAIN

Execution of manufacturer safety recall service resulted in immediate, catastrophic transmission malfunction and sudden loss of motive power upon leaving the franchised dealership, creating an imminent road hazard. Details of the Incident: Recall Intake: On XXX, the vehicle was driven into the authorized Ford dealership Cloninger Ford of Morganton in [XXX] under its own power for an open manufacturer safety recall involving the transmission molded leadframe and PCM software update to prevent sudden, unintended downshifts. Immediate Failure Post-Service: After technicians completed the recall service and returned the keys, the vehicle was driven out of the dealership lot. Upon reaching normal road speed and shifting from 3rd to 4th gear (less than 0.2 miles from the service bay), the transmission violently malfunctioned, lost forward drive engagement, and rendered the truck completely disabled and undrivable in active traffic. No road test was performed by the dealership prior to releasing the vehicle. Safety Risk: The sudden failure and inability to shift gears properly left the vehicle stranded in roadway traffic, presenting an immediate collision risk. The vehicle had to be limped back into the dealership service drive immediately. Remedy Failure & Denial: The dealership acknowledged that the recall-mandated PCM software calibration update triggered the severe transmission failure. However, both the manufacturer and the dealer are now claiming the failure is a "pre-existing condition," refusing to complete the safety remedy without charging the owner $7,000 for a full transmission replacement. The safety defect that prompted the recall was not remedied and was instead exacerbated to total mechanical failure during execution of the recall procedure.

Safety recall 26S28/26V237 was unable to be installed on my 2015 Ford F150. After receiving a "Check Engine Light" and a "Wrench Symbol Light", I took my truck to 3 different dealerships and all three could not perform the safety recall. At the first 2 dealerships, no solutions were tried. They called me to pick up the truck because they could not install recall. I took the vehicle to a 3rd dealership after recommendation from the 2nd dealership, and after 3 weeks they notified me as well that they could not perform install. A case number was created for this issue. I am still waiting for a solution from Ford to install this safety recall that is required by law to be installed.

The vehicle was previously taken to an authorized Ford dealership to complete Safety Recall 26S28 (NHTSA Campaign 26V237000) for unintended transmission downshifts. The dealer applied the mandated software patch. However, this safety remedy has completely failed.  While driving at highway speeds, the vehicle experienced severe mechanical gear grinding and twice suffered sudden, unprompted downshifts into a lower gear. This caused an immediate and dangerous spike in engine RPMs and a sudden deceleration, creating a high-risk highway crash hazard and a potential loss of vehicle control.  The physical hardware defect (the molded transmission lead frame) is actively failing and bypassing the software safeguard. The authorized dealer, Nielsen Ford of Morristown, is currently refusing to replace the defective hardware under the safety mandate without a permanent dashboard code, despite the vehicle displaying clear, dangerous physical symptoms of a failed recall remedy.

POWER TRAIN

Component: Power Train / Automatic Transmission (6R80 6-Speed) Description of Incident & Safety Hazard: My 2015 F-150 suddenly lost the ability to shift through its full range of gears and became completely locked between 3rd and 5th gears while driving. This sudden loss of power and gear range in active traffic created an immediate rear-end collision hazard. The vehicle threw diagnostic trouble codes P0720 (Output Shaft Speed Sensor) and P0722 (Output Shaft Speed Sensor No Signal). I have photographic proof of these active codes. The Safety Recall Loophole: I brought the truck to a Ford dealership for safety recall 26S28. However, the dealer only performed a PCM software update and did not replace the physical molded leadframe. Because safety recall 26S28 strictly excludes codes P0720 and P0722 from its replacement criteria, the dealer is completely unauthorized to replace the physical leadframe under this safety campaign, regardless of whether the codes are active. Inexplicably, Ford covers codes P0720 and P0722 under safety recall 24S37 (for older models), but forces 2015 owners with the exact same codes to rely on a non-safety Customer Satisfaction Program (26N04) which carries strict time/mileage limits. This is a dangerous technical loophole. A software patch on a vehicle with a physically failing speed sensor is a temporary band-aid, not a permanent safety fix. The physical leadframe is still defective and will fail again, presenting a continuous safety hazard. Ford must expand safety recall 26S28 to mandate the physical replacement of the molded leadframe for all vehicles presenting with leadframe-related codes, including P0720 and P0722. The vehicle is currently available for inspection.

NHTSA complaint #11757737 — an unverified report by a vehicle owner.

POWER TRAIN

The transmission intermittently enters a failure mode where the wrench warning lamp illuminates and the transmission locks into its current gear, with no further shifting. This has happened multiple times without warning, including at highway speed. It sometimes recovers on its own and resumes normal shifting, then fails again later. The safety risk is loss of gear selection while moving. Depending on the gear it locks into, the vehicle cannot accelerate to merge or maintain traffic speed, or the engine runs at high RPM with no upshift available. The manufacturer has issued a safety recall for this vehicle line citing unexpected transmission downshift as the hazard, which is the same underlying condition. My family rides in this vehicle and I no longer consider it safe. A Ford dealer confirmed the failure. Codes P0715 and P0717 (input/turbine shaft speed sensor circuit) were retrieved from the powertrain control module. No gear ratio codes and no slip codes were present, indicating an electrical fault rather than mechanical failure. The dealer performed the PCM reprogramming remedy under safety recall 26S28. The condition recurred the same day, on the drive home from the dealership, and has continued since. A software calibration cannot repair a degraded electrical connection, so the remedy did not address the failure on this vehicle. The manufacturer's stated root cause is degradation of electrical connections within the transmission molded lead frame. The transmission range sensor circuit and the turbine shaft speed sensor circuit both run on that same lead frame and terminate at the same case connector. Customer Satisfaction Program 26N04 covers lead frame replacement only when transmission range sensor codes are present. My vehicle is exhibiting failure of the same component through a different circuit on that component, and is excluded from the program despite the same part failing in the same manner.

vehicle: 2015 Ford F-150 XLT, 5.0L V8, approximately 148,000 miles. I previously had the related recall/software update performed on this vehicle. On two separate occasions the transmission performed a sudden, uncommanded downshift while driving at highway speeds. On one of those occasions the rear tires locked up / skidded. There was no warning, no driver input, and no diagnostic trouble codes (DTCs) were stored or displayed. After these events, a Ford dealership inspected the transmission and found metal debris in the transmission pan. This is how the current transmission problem was discovered. My symptoms match the defect described in NHTSA recall 26V237 / Ford campaign 26S28 (and the prior investigation PE25002 / EA26001): intermittent loss of Transmission Range Sensor signal due to degradation of the molded lead frame, resulting in unintended downshifts that can cause rear-wheel lock-up. I am requesting that Ford review this case for coverage or goodwill assistance related to the known lead-frame defect and the subsequent internal transmission damage.
