Lincoln bulletin TSB 26-2270
Lincoln filed this with NHTSA as a service bulletin dated Jun 3, 2026, received Jun 9, 2026, about the power train. It names 1 model year (2023). 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 26-2140. Reason for update: update the Parts list to correct the part description of the part number JM5Z-7N473-C, correct the part number XY-75W85QL to XY-75W85-QL and add a description note "Transfer Case Fluid, All markets", and update the Service Procedure (Steps 5, 7 and 8) to correct the WSM procedure steps. Some of the vehicles listed in the Model statement above may exhibit at least one of the following conditions: * Intermittent or permanent no reverse engagement. * Illuminated malfunction indicator lamp (MIL) with diagnostic trouble code (DTC) P0767 stored in the powertrain control module (PCM). In addition to the required conditions, the vehicle may also exhibit a harsh reverse engagement, DTC P0766 and/or P2703. This may be due to an internal mechanical concern with the selectable one-way clutch (SOWC).

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 Lincoln TSB 26-2270 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 26-2270 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 26-2270 cover?
The manufacturer filed it against 1 model year: 2023 Lincoln Nautilus. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
