Superformance Transmission Identification Guide
This guide will assist you in determining your Superformance car's Transmission model and
type that was selected during the installation or subsequent changes and upgrades thereafter.

Identify your transmission by the tag that is attached to one of the bolts that attaches the tail housing to the main case. Raise your car in a secure manner and note what is on the ID tag. This tag will be found attached to one of the bolts securing the tail shaft housing to the main case. Then compare the numbers to the chart below. You should be able to match one of the number under the column identified as "Part Number". (Note, just because the tag may say "3550" that does not mean it is!)
