Ford bulletin TSB 26-2050
What it saysThis article supersedes TSB 24-2142 to update the Parts List, Service Procedure (Steps 1-2), and increase the labor operation allowances to reprogram the PCM/TCM. NHTSA’s full summary ↓
Ford filed this with NHTSA as a service bulletin dated Feb 16, 2026, received Feb 17, 2026, about the power train. It names 15 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 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 article supersedes TSB 24-2142 to update the Parts List, Service Procedure (Steps 1-2), and increase the labor operation allowances to reprogram the PCM/TCM. Some of the vehicles listed in the Model statement above may exhibit all of the following conditions: Poor shift quality Illuminated powertrain malfunction (wrench) indicator with diagnostic trouble codes (DTC) P2704 and P0771 stored in the PCM/TCM. This may be due to a calibration in the TCM and/or wear between the input shaft and the E clutch hub causing the input shaft O-rings to become damaged resulting in an open E clutch circuit. Additional model information: 6.7L Diesel Engine 2022-2024 F-550 or F-600 F-Super Duty vehicles built on or before 15-May-2024 with over 5,000 miles (8,000km)

Read by machine from the document NHTSA serves (3 pages), read Sep 29, 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 9 model years this bulletin names have filed 437 complaints with NHTSA since 2015. 56 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.
The contact owns a 2024 Ford F-350. The contact stated that while driving at an undisclosed speed, the transmission unexpectedly downshifted. There was no warning light illuminated. The vehicle was taken to the dealer but was not diagnosed or repaired. The dealer informed the contact that a software update had been completed on the TCM.

Slight vibration at highway speed accompanied by faint grinding noise. Ford installed front auto locker to only one front wheel and a dummy full time locker to right front wheel in non trimmer 2024 f250 and f350s.

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 26-2050 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 26-2050 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 26-2050 cover?
The manufacturer filed it against 15 model years: 2024 Ford F-250 Super Duty, 2023 Ford F-250 Super Duty, 2022 Ford F-250 Super Duty, 2024 Ford F-350 Super Duty, 2023 Ford F-350 Super Duty, 2022 Ford F-350 Super Duty 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 F-Super Duty F-550/F-600: built on or before 15 May 2024 — the build date is on the certification label in the driver’s door jamb.
