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 4 model years this bulletin names have filed 437 complaints with NHTSA since 2015. 180 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 2022 Ram 3500, the 13 owners who gave an odometer reading for Power Train reported it at a median of 16,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
The transmission lost gears 1 through 4 on the freeway in traffic. We were going approximately 25mph in the fast lane when it happened. We were lucky enough to have enough speed to make it to the shoulder, but were left stranded on the shoulder. Truck is at dealer needing a transmission replacement that can't be ordered at this time

2022 Ram 2500 · Power Train · filed with NHTSA Feb 13, 2023
Transmission just started shifting very hard causing the truck to shake. Truck was fine last week, mileage is 9600. Have notified the dealer, they said to bring it it in. There is no warning lights or alerts
2023 Ram 2500 · Power Train · filed with NHTSA Sep 21, 2024
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 Ram S2321000007 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 S2321000007 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 S2321000007 cover?
The manufacturer filed it against 4 model years: 2023 Ram 2500, 2022 Ram 2500, 2023 Ram 3500, 2022 Ram 3500. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
