Manually looking up the serial number helps you verify that you're getting the right parts and service, which is especially important when you're sourcing replacement components. This extra verification can save you from costly mistakes and keep your vehicle running smoothly.

In July 2005, Allison redesigned its nameplates. On newer nameplates, the model number no longer appears—it has been replaced by the serial number as the primary identifier. The transmission product family can be identified by the first two digits of the serial number: serial numbers beginning with "63" or "65" belong to the 1000/2000 Product Family, while "66" indicates the 4000 Product Family. This design change was made to provide only the information essential for identification, so your serial number becomes even more important for modern units.

Before you can use any lookup tool, you need to find the serial number on your transmission. Allison installs a metal identification tag (also called a nameplate) on every transmission it manufactures. This tag contains the critical information you need.
