Does this affect my vehicle?
The manufacturer did not publish a build-date range for this recall, so the model and year list below is the only way to tell whether your vehicle is covered.

What the defect is
Allison Transmission, Inc. (ATI) is recalling certain Emergency Vehicle Series 6th Generation Transmission Control Modules (TCM). The transmission control module (TCM) may fail to achieve the 4th gear transmission lockup needed to initiate the water pump.
What could happen
Failure to achieve 4th gear lock up may prevent the vehicle from achieving the full sequence needed to pump water, which can increase the risk of injury in an emergency.
What gets fixed
Vehicle manufacturers will update the TCM software, free of charge. ATI notified the affected vehicle manufacturers on July 31, 2023.
Parts involved
- ATI 6th Generation TCMSoftware levels BC221-22Transmission control module
Part numbers are as filed by the manufacturer and are listed for reference. Your dealer will confirm the correct part for your vehicle.

Your rights
A safety recall repair is free. Under US federal law the manufacturer must fix a safety defect at no cost to you — no charge for parts, labor or diagnosis — whether or not you are the original owner. A dealer cannot charge you for recall work, and cannot require you to have bought the vehicle from them.
That entitlement is not unlimited. It applies where the vehicle was first sold less than 15 years before the recall was announced — 5 years for tires. Past that a manufacturer may still do the repair free of charge, and many do, but they are no longer obliged to. This recall was reported on 24 July 2023.
To arrange the repair, contact any franchised dealer for the brand. If a dealer refuses the work or tries to charge for it, you can report that to NHTSA at nhtsa.gov/recalls or on 1-888-327-4236.

Everything on this page — the models listed, the build dates and the repair figures — comes from the manufacturer's filing to NHTSA and describes the vehicle line as a whole, not any individual car. Only the manufacturer can confirm whether a specific vehicle is affected, and whether its recall work has already been carried out. Check yours by VIN and read the official notice at nhtsa.gov/recalls.
Additional notes
Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.nhtsa.gov.
Check your own vehicle
This page describes the recall, not any one car. To see which recalls cover a specific vehicle, search by make, model and year.
A VIN lookup here identifies your vehicle and shows recalls issued for that make, model and year. It cannot tell you what is still open on your individual car - only the manufacturer knows that. Search by VIN instead, or check your VIN at nhtsa.gov for whether a recall is still open on your individual car.
