Search yielded a bunch of nothing for me. I'm trying to figure out what type of tranny is in my bronco without having to crawl under it(hard to get oustide with 2kids in the winter). It's a 1988 FSB 351w, as far as I know it's still stock. I know it was rebuilt. But I think that's it. If anyone could even point me in the right direction, I'd appreciate it.
