What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationThis bulletin supersedes TSB 25-2132. Reason for update: update the Part List Description and Labor Times Description Some of the vehicles listed in the Model statement above may exhibit at least one of the following conditions: * Harsh engagement * Delayed engagement * Harsh shift * Delayed shift * Illuminated malfunction indicator lamp (MIL) with diagnostic trouble codes (DTC) P0751, P0752, P0756, P0757, P0761, P0762, P0766, P0767, P0771, P0772, P2700, P2701, P2702, P2703, P2704, P2705, P2707, P2708, P0729, P0731, P0732, P0733, P0734, P0735, P0736, P076F, P07D9, P07F6 and/or P07F7 stored in the powertrain control module (PCM) or transmission control module (TCM) This may be due to axial movement of the CDF clutch cylinder (7H351) sleeve causing hydraulic circuit leaks. NOTE: If internal transmission service is required to address a concern detected with the CDF clutch cylinder following this article, technicians should carefully inspect and replace other transmission components and flush transmission fluid cooler only as necessary to confirm proper function.

Read by machine from the document NHTSA serves (7 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 8 model years this bulletin names have filed 1,781 complaints with NHTSA since 2015. 833 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 2019 Ford Expedition, the 59 owners who gave an odometer reading for Power Train reported it at a median of 77,000 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 2019 Ford Expedition. The contact stated a rattling sound was heard coming from the engine compartment after starting the vehicle. The contact stated no warning lights were illuminated. The independent mechanic was called and stated that the failure was related to the cam phaser, which needed replacement.
2019 Ford Expedition · Power Train · filed with NHTSA Oct 25, 2021 · ODI 11438077
While driving, the vehicle repeatedly hesitated during gear changes, lost power, and then abruptly jerked back into gear. This occurred intermittently for over a month without any warning messages, creating unpredictable and unsafe driving conditions. As the issue worsened, the vehicle began losing power more frequently.
2021 Lincoln Navigator · Power Train · filed with NHTSA Feb 10, 2026 · ODI 11716941
The contact owns a 2020 Ford Expedition. The contact stated while driving at 10-20 MPH a week after purchasing the vehicle brand new, the vehicle started jerking. There was no warning light illuminated. The contact continued driving. However, the failure recurred while driving the entire day.

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 25-2476 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 25-2476 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 25-2476 cover?
The manufacturer filed it against 8 model years across 2 brands (Ford and Lincoln): 2021 Ford Expedition, 2020 Ford Expedition, 2019 Ford Expedition, 2018 Ford Expedition, 2021 Lincoln Navigator, 2020 Lincoln Navigator and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
