My transmission is starting to go as in 3rd gear my AOD in my 92 tbird sport revs up really fast past 2500 until it hits 4000 before catching on so I think the gear is shot. I found a 87 tbird 302 transmission for sale, would that fit in bird? If not what would I need to do to make it fit? And would it be as good as my AOD was? Any help is appreciated.
