LOCATE YOUR ALLISON TRANSMISSION SERIAL NUMBER (2024)

The serial number of an Allison transmission may be located on the transmission data plate. This can be located on the side of the transmission.

This data plate is usually found on the lower rear face of the rear housing. The serial number of an Allison transmission usually contains 10 numbers, and is listed just under the model number of the transmission. The serial number is typically shown on the bottom left of the transmission data plate.

Once a transmission has been put to good use, some of the information contained on the data plate may wear off with time. Therefore, it is important to know where this number may be located on the data plate, and just how many numbers you are looking for.

An Allison transmission is typically for the use of a medium to heavy duty truck. When looking to buy a replacement transmission, it is important to locate your transmission serial number so this information can be given to your sales representative. This information is needed before quoting a replacement engine, as it determines which exact transmission will be a fit for the application.
