Building a custom car or truck includes putting together a drivetrain that’s suited for your application, and one of those key aspects is the transmission. Finding that transmission is as easy as going to a junkyard or searching online, but determining what type of Ford transmission it is—and what gearing comes with it, what vehicle it was from and what application it’s best for—takes a few steps.
Take a picture of the transmission. Take several shots of all angles, including the pan, the bellhousing and all the mounting points.
Measure the distance from the bellhousing to the rear of the transmission.
