Ford took eleven years to recall the 2015–2017 F-150 for transmissions that drop gears without being asked. Owners now say the fix has been pulled back as well.
Several owners on the F-150 Forum report dealers telling them that Ford has put recall 26S28 on hold. One owner says he dropped his truck off for the update and picked it up still unrepaired. The service advisor hadn’t heard about the hold either. Ford’s public recall page still says a remedy became available July 9, and when we checked it gave no restart date. That leaves 1.39 million pickups stuck between a recall notice and a repair.
What’s actually failing
The recall covers 1,392,935 trucks, according to Ford’s Part 573 report. All of them have the six-speed 6R80 automatic and were built between March 12, 2014, and August 18, 2017.
The culprit is the lead frame, the molded wiring carrier that sits on the valve body inside the transmission. Ford says years of heat cycles and vibration can degrade its electrical connections. When that happens, the powertrain computer briefly gets a garbage reading from the transmission range sensor. The computer believes the bad reading and commands a downshift.

NHTSA’s engineering analysis summary shows how severe that can be. Under Ford’s shift logic, a truck traveling between 35 and 64 mph can drop from sixth to second. Ford calls that its worst case. Of the 329 owners in NHTSA’s complaint pool, 43 percent reported at least one rear-wheel lockup. If you’ve ever had a rear-drive truck with an empty bed step out on a wet on-ramp, you can picture it.
The same NHTSA document flags a second problem. The agency’s test center found that if the sensor signal drops out while a truck is reversing up an incline, the transmission can go to neutral and the truck can roll forward. The recall paperwork describes only the downshift.
A software patch for a hardware problem
The remedy shows Ford’s priorities. Most trucks get a powertrain control module recalibration that gives the system “additional time” to recognize a failing sensor before it acts on the bad signal. In other words, the truck learns to doubt itself for a beat before it does anything drastic.
The software doesn’t repair the lead frame. It only stops the computer from acting on the lead frame’s bad readings. Physical lead frame replacement is reserved for trucks that have already logged certain diagnostic trouble codes. Ford’s recall page backs those parts with a 15-year/150,000-mile extended warranty.
That approach makes sense from Ford’s side. Swapping a lead frame means dropping the pan and pulling the valve body, and doing that on 1.39 million trucks would be enormously expensive. The hold, though, shows the weak point of that strategy. If owners are right that the pause is tied to parts or problems with the update, the “cheap” software fix depends on the same hardware supply it was meant to avoid.
Ford has been here before
This failure is related to an earlier one. Ford fixed 2011–2014 F-150s through four separate recalls (16V-248, 19V-075, 19V-433, and 24V-444) for a different sensor, the output shaft speed sensor, which could cause sixth-to-first downshifts. Ford told NHTSA the 2015–2017 problem is a distinct failure mode. Owners may not care much about the distinction.

The timeline is the uncomfortable part. Ford’s own chronology lists related reports going back to April 24, 2015. As of April 2, 2026, it counted 444 warranty claims, 121 field reports, 105 customer service reports, 316 owner complaints to NHTSA, two injuries, and one crash. The recall only followed after NHTSA escalated its probe to an engineering analysis in January.
What owners should do now
- Don’t clear your codes. This is the most important one. Lead frame replacement depends on trouble codes stored before the software update. If you’ve had a downshift or a check-engine or wrench light, have a dealer read and document the codes. Wiping them with a $20 scan tool could cost you a free transmission repair.
- Get dealer repair orders for every incident. Your notes are useful, but a dated repair order is what counts if you need to file a claim later.
- Chase reimbursement. NHTSA found that 114 of the 329 complaining owners had already replaced a lead frame or valve body. Ford says it is using its general reimbursement plan, so file your receipts.
- Push for a loaner if your truck is grounded. Ask the dealer and Ford customer service (1-866-436-7332) in writing. If you get nowhere, file a complaint with NHTSA, which is still watching this defect closely.
- Buyers, run the VIN. Many of these trucks are being traded in and listed for sale. Until Ford restarts the program, an “open recall, remedy pending” status on one of them may mean exactly that, with no timeline attached. Did your dealer tell you 26S28 is on hold, or did you find out from the forums like everyone else? What is your service department saying?
