Ford filed this with NHTSA as a service bulletin dated Sep 22, 2026, received Sep 30, 2026, about the power train. It names 22 model years across Ford and Lincoln (2022–2024). A service bulletin is not a safety recall: it is the manufacturer telling its dealers how to diagnose or repair a condition, and whether the work is paid for depends on the warranty in force. Quoting the number at a service desk can save a diagnosis.

What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationWhat it applies to, as the document itself states it — the build window in the manufacturer’s own words, read by machine from the PDF NHTSA serves. The build date is on the certification label in the driver’s door jamb; the dealer settles a borderline vehicle by its VIN.
This bulletin supersedes 26-2309. Reason For Update: update the Model section to remove Aviator 10R80, update the Parts list to add 3.3L to W520514-S440, and add L1MZ-7Z490-G valve body separator plate for Aviator. Some of the vehicles listed in the Model statement above may exhibit at least one of the following conditions: * Harsh 3-4, 4-5 upshifts * Harsh 5-3, 4-3 downshifts * Harsh reverse engagements These symptoms may be worse when cold. This may be due to the F clutch friction plates brinelling into the clutch and planetary container cylinder (7B177).

Read by machine from the document NHTSA serves (15 pages), read Sep 30, 2026. A part number is shown only where it matches Ford’s own catalogue shape, an operation only with its code and time, and a description only where the reader got it whole; anything it could not settle is left out, and the PDF is the record. Times are the manufacturer’s warranty allowances, not a quote. Listings and prices on eBay Motors are the seller’s.
Affiliate disclosure: some links on this page are affiliate links. If you request a quote or buy through them we may earn a commission at no extra cost to you. Nothing on this page changes because of it.
The summary is NHTSA’s abstract of the document, as filed under 49 CFR 579.5. One communication is usually filed as several documents — the bulletin, a dealer notice, an owner letter — and the number on any of them finds this page. A PDF link is shown only once NHTSA’s own server has been seen to serve that document; the rest are checked over the following nights. Quote the number at a service desk; it is what the dealer’s system is keyed on.

What owners reported
Source: NHTSA complaint databaseOwners of the 22 model years this bulletin names have filed 2,648 complaints with NHTSA since 2015. 640 of them name Power Train — the same broad component group this bulletin is filed under. NHTSA groups complaints coarsely, so that means the same area of the vehicle, not necessarily the same fault.
On the 2022 Ford F-150, the 55 owners who gave an odometer reading for Power Train reported it at a median of 30,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
The contact owns a 2023 Ford Ranger. The contact stated while driving at an undisclosed speed, the vehicle inadvertently decelerated to 40 MPH, and the vehicle then shifted into 4WD-Low independently. As a result of the failure, the vehicle dramatically decelerated and skidded to a complete stop. The 4WD warning light was illuminated.
2023 Ford Ranger · Power Train · filed with NHTSA Mar 28, 2025
Passenger side rear axle retention bolt sheared off. Discovered during routine maintenance / tire rotation. Unknown how safety was at risk -- dealer told me once discovered that the vehicle would be repaired under warranty, and they could do in 24 hours, so no discussion about unsafe to drive as others have reported they were told.
2022 Ford F-150 · Power Train · filed with NHTSA Nov 20, 2022
The contact owns a 2023 Ford Transit. The contact received notification of NHTSA Campaign Number: 24V102000 (Power Train); however, the part to do the recall repair was unavailable. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue.
2023 Ford Transit · Power Train · filed with NHTSA Sep 19, 2024
A complaint is one owner’s account, not a defect finding, and a bulletin is not a recall. Nothing here says this bulletin was issued because of these complaints, or that the repair it describes fixed them. Complaint files on this site begin in 2015.

Common questions
Source: NHTSA, 49 CFR 579.5Is Ford TSB 26-2408 a recall?
No. A service bulletin is a manufacturer communication filed with NHTSA under 49 CFR 579.5; a safety recall carries an NHTSA campaign number (two digits, a letter, six digits) and a federal duty to repair for free. Check the vehicle’s recalls by VIN at nhtsa.gov/recalls, or on its page here.
Is the TSB 26-2408 repair free?
Not automatically. A service bulletin describes how to diagnose or repair a condition; who pays depends on the warranty in force, any extension, and the dealer. Quoting the number can save a diagnosis either way.
Which vehicles does TSB 26-2408 cover?
The manufacturer filed it against 22 model years across 2 brands (Ford and Lincoln): 2024 Ford Expedition, 2023 Ford Expedition, 2022 Ford Expedition, 2024 Ford Explorer, 2023 Ford Explorer, 2022 Ford Explorer and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone. The document itself sets the build window: 2022-2024 Expedition: built 16 Aug 2022 – 23 Sep 2024; 2022-2024 Explorer: built 16 Aug 2022 – 23 Sep 2024; 2022-2024 F-150: built 16 Aug 2022 – 23 Sep 2024 — the build date is on the certification label in the driver’s door jamb.
