Ford filed NHTSA recall 26V237000 on April 14. It covers 1,392,935 F-150 pickup trucks — 2015, 2016, and 2017 model years — for a transmission that can shift from 6th gear to 2nd without any driver input, at highway speeds.
That's not a rough shift. A forced downshift at 70 mph spikes RPMs, causes the truck to decelerate sharply, and can lock the rear wheels momentarily. Ford has two confirmed injuries and one accident in the file. There are 444 warranty claims and 105 customer service reports linked to the issue.
What's Actually Breaking
These F-150s use Ford's 6R80 six-speed automatic. Inside the transmission is a lead frame: a wiring assembly that connects the Transmission Range Sensor (TRS) to the Powertrain Control Module (PCM). The TRS tells the PCM where the gear selector is positioned. The PCM acts on that information to control shifting.
Over time, heat cycles and vibration degrade the electrical connections inside the lead frame. When those connections fail intermittently, the PCM gets a false signal from the TRS. It interprets that signal as a shift command and responds accordingly — dropping the truck into 2nd gear without the driver doing anything.
NHTSA flagged the issue in October 2024. The agency elevated it to a formal Engineering Analysis in January 2026. Ford's internal review committee approved the recall on April 7 and filed it with NHTSA a week later. Ford estimates roughly 1% of the 1.39 million recalled trucks — about 13,900 vehicles — currently have the active defect. The rest are at risk as the lead frame continues to age.
Affected Vehicles
| Model Year | Transmission | Production Window | Vehicles in Recall |
|---|---|---|---|
| 2015 F-150 | 6R80 6-speed automatic | Mar 2014 – Aug 2017 | Included |
| 2016 F-150 | 6R80 6-speed automatic | Mar 2014 – Aug 2017 | Included |
| 2017 F-150 | 6R80 6-speed automatic | Mar 2014 – Aug 2017 | Included |
The 6R80 pairs with multiple engine options across those years. The 10-speed 10R80 — introduced on some 2017 F-150s and standard from 2018 onward — is not affected. Your VIN determines whether you're in the recall population. Ford's internal campaign number is 26S28; the NHTSA number is 26V237000.
The Fix
Dealers will reprogram the PCM with revised calibration software. The update gives the control module more time to distinguish a legitimate TRS signal from a momentary failure before commanding a shift. If the truck already shows specific diagnostic trouble codes (DTCs) tied to TRS signal errors, the dealer will also replace the lead frame assembly. Both repairs are free.
Interim owner notification letters mail between April 27 and May 1. Final remedy notifications follow July 13 through 17. Owners don't have to wait: dealers can begin repairs under recall 26S28 now.
What This Means If You're Shopping a Used 2015-2017 F-150
CarScout's market data as of April 12, 2026 shows more than 3,400 active listings for 2016 and 2017 F-150s alone. The 2016 median sits around 127,000 miles; the 2017 around 118,000 miles. These are high-mileage trucks, most of them past any original powertrain coverage, selling in the $15,000 to $35,000 range depending on trim and condition.
Most private sellers haven't received the notification letter yet. That creates a short window where the recall is real, the VIN check confirms it, but the seller may not have factored it in.
| Situation | What To Do |
|---|---|
| Recall not yet completed | Check VIN, negotiate; fix is free at any Ford dealer |
| Recall already closed | Confirm with Ford owner portal printout; closed = serviced |
| Truck shows symptoms | Test at highway speed; harsh shudder or unexpected downshift means lead frame is failing — confirm recall coverage before signing |
A transmission recall doesn't automatically kill a vehicle's value. What it does is give you a factual basis to negotiate during the short window before sellers get the April 27 letters. After that, most dealers will have already addressed it in their prep process.
If you're already driving a 2015-2017 F-150, there's no reason to stop. The fix is free and doesn't require an appointment before July — though if your truck is shifting oddly at highway speeds, get it in sooner. Dealers can perform the repair under the recall number right now.
FAQ
Which F-150 years does recall 26V237000 cover? 2015, 2016, and 2017 Ford F-150 trucks built between March 12, 2014, and August 18, 2017, equipped with the 6R80 six-speed automatic transmission. The total recall population is 1,392,935 vehicles. Trucks with the 10-speed 10R80 transmission are not affected.
What does the unintended downshift feel like? A sudden harsh downshift at highway speed — potentially from 6th to 2nd — without the driver touching the gear selector. RPMs spike, the truck decelerates sharply, and rear wheels can momentarily lock. If you've experienced this in a 2015-2017 F-150, Ford has confirmed two injuries tied to the issue and the recall covers your repair at no cost.
Do I have to wait for the owner letter to get it fixed? No. Dealers can begin performing the PCM software update now under recall 26S28. If you own a 2015-2017 F-150 with the 6R80, check your VIN with CarScout's recall lookup and schedule service without waiting for the mail.
