What the 26S28 recall means for your F-150
This recall targets one fault in one transmission, and the fix costs you nothing.
The one-paragraph answer
Recall 26S28 is Ford’s number for NHTSA recall 26V237. It covers 1,392,935 2015–2017 F-150 trucks with the six-speed automatic, where a faulty sensor signal can trigger an unintended downshift into second gear. Ford’s fix is a free powertrain control module (PCM) software update at a Ford dealer, launched on 9 July 2026, and Ford estimates about 1% of recalled trucks actually carry the defect.

- Felt a sudden downshift or seen a wrench light? Read why it happens, then what to do before the update.
- Already paid for a lead frame or transmission repair? Go straight to the refund section.
This recall is one entry in our year-by-year guide to documented F-150 problems.
ℹ️ Safety Note: An unexpected downshift at speed can make the rear tires slide and cause loss of control. This article explains the recall for general understanding only. Have any warning light or sudden downshift inspected by a Ford dealer.
Is your F-150 covered by 26S28?
Build date and transmission decide coverage, not model year alone.
Build dates and transmission, not just model year
Ford’s Part 573 safety recall report for 26V237 limits the campaign to F-150s with the 6-speed automatic built between 12 March 2014 and 18 August 2017. Ford says these trucks weren’t built in VIN order, so check your exact truck with our rather than going by the year. For 2017, the 3.5L EcoBoost came only with the new 10-speed, so those trucks fall outside this recall.
Which Ford downshift recall covers which F-150
| Campaign | Applies To | Fault | Downshift Into |
|---|---|---|---|
| 16S19 | Certain 2011–2012 F-150 (specific build window) | Output shaft speed sensor | Lower gear |
| 19S07 / 19S19 | 2011–2013 F-150 (19S19: 2013 5.0L and 6.2L) | Output shaft speed sensor | First gear |
| 24S37 | 2014 F-150, 6R80 | Output shaft speed sensor | First gear |
| 26S28 | 2015–2017 F-150, 6-speed, built 12 Mar 2014–18 Aug 2017 | Transmission range sensor signal | Second gear |

Why a 2015–2017 F-150 drops into second gear
The problem starts with wiring inside the transmission, not the gears themselves.
The lead frame, the TRS and the PCM
The lead frame is a wiring assembly inside the transmission that carries sensor signals, including the transmission range sensor (TRS) signal. Ford’s NHTSA filing says heat cycling and vibration degrade its electrical connections. The PCM then briefly reads the wrong range position and can command a downshift, at worst from sixth straight to second. Ford’s owner FAQ describes the cause as a weld quality variation in the lead frame wiring.
🔍 Why It Happens: Dropping to second at highway speed turns the engine into a sudden brake on the rear axle. That abrupt slowdown is why the rear tires can slide until the truck loses speed.
Warning lights that may, or may not, appear first
Ford says some trucks show a wrench light or check engine light first, but not all. As of 2 April 2026, Ford counted 444 warranty claims and 316 NHTSA complaints among reports covering 891 trucks. It linked two injuries and one accident to the problem. Out of 1.39 million trucks, that makes the fault rare, but serious enough to fix.
Is the 26S28 fix just a software update?
Mostly, but not always.
What the new PCM calibration changes
Every recalled truck gets a PCM calibration update. Ford says it gives the system more time to recognize a failing TRS before it commands a downshift. It changes how the computer reacts; it doesn’t repair worn wiring.
When the dealer replaces the lead frame instead
If your truck shows a check engine or wrench light before or after the update, the dealer runs a diagnostic. If specific transmission diagnostic trouble codes turn up, Ford replaces the lead frame at no cost under program 26N04.
The work is dealer-only; Ford’s 26S28 recall questions page says Ford Mobile Service can’t do it. Participating dealers offer free pickup and delivery.
📋 On the Record: Ford recall 26S28 / NHTSA recall 26V237 covers 2015–2017 F-150s with the 6-speed automatic built 12 March 2014–18 August 2017. Ford launched the software remedy to dealers on 9 July 2026, and remedy letters were scheduled for 13–17 July 2026. Status: open, remedy available. Checked 24 September 2026.
✅ Do This: When you book, ask the dealer: “Were any transmission trouble codes stored before the 26S28 calibration, and does my truck qualify for lead-frame replacement under 26N04?”
Can you get a refund if you already paid for a repair?
Ford runs 26S28 refunds under its general reimbursement plan, and the dates matter.
Who qualifies, and the dates that matter
Ford’s recall refund rules set three conditions:
- You may qualify if you paid before your owner notification letter was mailed.
- Work done outside a Ford dealer only qualifies if you paid before the recall announcement.
- No refund is processed until the recall is completed on your truck.
Two answers we couldn’t confirm in any Ford or NHTSA document as of 24 September 2026:
- the exact 26S28 cutoff date;
- whether an owner-paid lead-frame replacement counts.
Ask your dealer to check both against your receipts.
What to bring to the dealer
Bring your original repair receipts, ideally showing the date, your VIN and the work done. Ford accepts them at any US Ford dealer. If Ford mails you a program reimbursement letter instead, it includes a PIN for Ford’s Ownership Care Reimbursement website.
How long Ford covers the lead frame after the recall
Program 26N04 is your safety net if the lead frame fails later.
What triggers a free lead-frame replacement
A warning light plus transmission trouble codes, confirmed by a dealer diagnostic, triggers a free replacement under 26N04. Ford’s earlier lead-frame programs for 2011–2013 trucks (16N02 and 19N01) ran 10 years or 150,000 miles. Those were different programs, and their terms don’t automatically carry over to 26N04.
Keep the letter: coverage limits
As of 24 September 2026, we couldn’t find 26N04’s time and mileage limits in any document we could check. Owner reports of the terms conflict with each other. Your 26N04 letter, or Ford’s recall page for your VIN, is the only reliable source, so keep it with your service records.
What to do before and after the 26S28 update
Ford has not told owners to park their trucks.
If a warning light is on
Ford says you can keep driving, and 26S28 has no Stop-Drive or Park-Outside instruction. If the check engine or wrench light comes on, Ford says to take the truck to a dealer immediately.
⚠️ Watch Out: A warning light may not appear before a downshift. If you’ve already felt one, tell the dealer when you book, even if no light is on now.
Checking status yourself
Run your VIN through NHTSA’s recall lookup or call Ford on 1-866-436-7332 and quote 26S28. After the visit, check that your repair order shows 26S28 as completed.
