66-77 Bronco

Automatic Transmission Components for early Ford Bronco

The 66-77 Ford Broncos had one option when it came to an automatic transmission. The C4 Automatic Transmission gave the early Broncos a quality, reliable 3-speed automatic transmission option. For those looking for an upgrade from the stock C4 Transmission, we also offer adapter components to convert your Bronco to either an AOD (Automatic Overdrive) Transmission or a C6 Automatic Transmission. The AOD is a great, relatively easy way to add an automatic transmission with overdrive to your early Bronco. The C6 requires quite a bit more modification to install and is a very stout replacement for the C4 transmission.
