Ford bulletin TSB 23-2160

What it saysSome 2020 F-Super Duty vehicles equipped with a 6.2L or 7.3L engine and a 10R140 transmission may exhibit an illuminated powertrain malfunction (wrench) indicator with diagnostic trouble code (DTC) P07F7 stored… NHTSA’s full summary ↓

Ford filed this with NHTSA as a service bulletin dated May 23, 2023, received May 29, 2023, about the power train. It names 7 model years (2020). 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.

Superseded. Ford replaced this bulletin with TSB 25-2357 dated Aug 7, 2025. Read that one first; this page stays as the record of what was filed under TSB 23-2160.

What it applies to, as NHTSA’s summary states it — build dates and equipment as the manufacturer filed them. The dealer checks the VIN and the build date on the door jamb; a vehicle outside the window is not covered by this bulletin.

Some 2020 F-Super Duty vehicles equipped with a 6.2L or 7.3L engine and a 10R140 transmission may exhibit an illuminated powertrain malfunction (wrench) indicator with diagnostic trouble code (DTC) P07F7 stored in the powertrain control module (PCM) and a loss of 10th gear. The vehicle may also exhibit harsh engagements and poor shift quality. This may be due to the sleeve in the CDF clutch cylinder shifting axially causing hydraulic circuit leaks. To correct the condition, follow the Service Procedure to replace the CDF clutch cylinder.

Read by machine from the document NHTSA serves (4 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 database

Owners of the 3 model years this bulletin names have filed 483 complaints with NHTSA since 2015. 137 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 2020 Ford F-350 Super Duty, the 28 owners who gave an odometer reading for Power Train reported it at a median of 69,500 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 2020 Ford F-350. The contact stated that while attempting to reverse the vehicle, the engine revved but the vehicle would not move. The power train malfunction warning light illuminated. The vehicle was taken to the dealer and diagnosed with number one planetary and ring gear assembly failure.

The vehicle is experiencing very erratic shifts between gears. The transmission is slingshot shifting in all gears between 3rd through 6th. If this continues it will undoubtedly blow the transmission out.

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 579.5

Is Ford TSB 23-2160 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 23-2160 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 23-2160 cover?

The manufacturer filed it against 7 model years: 2020 Ford F-250 Super Duty, 2020 Ford F-350 Super Duty, 2020 Ford F-450 Super Duty, 2020 Ford F-550 SD, 2020 Ford F-600 SD, 2020 Ford F-650 SD and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
