Re: Transmission codes
your transfer case is a Borg Warner 13-56, as long as its the stock one. And your transmission should either be a ford c-6, an s5-42, or a mazda m5od. the two later ones being 5 speed manuals and the first being a 3 speed automatic. Don't take my word for it though. My trans. is an E40D and they supposedly didnt start putting those in broncos till 91....my bronco is a 90...go figure!!!
hope i helped
