Early Bronco Transmission

Early Bronco Transmission

The early Bronco came from Ford with either a 3-speed manual transmission or a Ford C4 3-speed automatic transmission. The automatic transmission was only offered in 73-77 Ford Broncos and did not have an overdrive gear. We offer a variety of parts to rebuild your factory early Bronco transmission or upgrade to a modern 4-speed or 5-speed manual transmission or automatic transmission with overdrive.
