Ford bulletin TSB 26-2309
Ford filed this with NHTSA as a service bulletin dated Jul 2, 2026, received Jul 1, 2026, about the power train. It names 17 model years (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 communicationThis bulletin supersedes 26-2241. Reason For Update: update the parts list to correct the claim quantity of the part number JB3Z-4B496-B from 3 to 6. 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).

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.

Common questions
Source: NHTSA, 49 CFR 579.5Is Ford TSB 26-2309 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 26-2309 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 26-2309 cover?
The manufacturer filed it against 17 model years: 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.
