I recently purchased a 93 Bronco 302 4x4 with hopes of fixing it up (of course) and am having problems with the transmission. The motor seems fine but has a little miss which I think is a fuel injector. My big problem is the transmission goes through 1st, 2nd and 3rd gears really fast then starts jumping or stalling (not sure how to describe) around 25-30mph. I can manually shift through the gears but I have the problem again when I shift into drive. When I bought the Bronco it had the steering column cover off and the overdrive wires disconnected. The guy said they were sparking so he just never hooked them back up. I hooked them back up and there wasn’t any sparking and it drove well for about a week and it started messing up. A friend of mine said I would have to replace the transmission and I am hoping there is a chance that isn’t true. It’s something I want to do in the future but wanted to tackle a few other things first. It has 198,000 miles on it and everything looks stock and in pretty good condition without any major rust anywhere. Could the problem be a sensor or something else kinda simple?
