Bronco Drivetrain & Transmission

When it comes to dealing with the Early Bronco drivetrain, you have mounds of options. At Tom's Bronco Parts we have the techs available to help you decipher these options and make the right buying decision for your Classic Bronco. Whether you are building it for a daily driver or wanting to beef it up and show up your buddies in their J**ps, we can get you where you want to be. Maybe we're partial, but we think our techs are the best in the business to build up your 66-77 Bronco custom differential or they can talk you through what you need to do it yourself. Want to upgrade your 3-speed Manual Transmission or your stock C4 Automatic Transmission? We offer some great options including the NP435 4-speed Manual Tranny, NV3500 & NV4500 5-seed Manual Transmissions as well as adapter kits for the Ford AOD & C6 Automatic Transmissions.

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.

We have the parts you need to rebuild or replace your factory 3-speed manual transmission or to upgrade to an NP435 4-speed, NV3550 5-speed or NV4500 5-speed manual transmission.
