How to Identify Ford Transmissions

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.

      C4: 10-by-9-inch pan with 11 bolts. There is also a bulge in the front passenger corner.
      C5: Similar pan to C4 but has a hump in the middle.
      C6: Rectangular pan that has 17 bolts. Longer on the front and rear than on the sides.
      AOD: Similar pan to C4 with corners angled slightly; 14 bolts secure the pan.
