As much as you love your Bronco for the amazingly capable machine it is from the factory, you probably love to rip stuff out and improve it even more. For many of us the stock transmission is fairly high on that upgrade list.
The 3 speed manual or C4 automatic...
Tech article by Josh Wilczynski (kontinu)
