Transmission Identification Ford

This page is designed to assist you in identifying the transmission installed in your vehicle. We are making the assumption that your vehicle has the original type transmission that was installed at the factory. In most cases, if your vehicle has been converted from an overdrive to a 3-speed, you can still use this guide for identification. If the drivetrain in your vehicle has been customized in any other way, you should call our techs for help identifying your transmission.
