My tranny is going/gone in my 90 Ranger 2.9 4x4. It's a 5 speed manual, but I know there are different ones that it could be. I don't have the door stickers to tell me anything about it. I want to get a new/rebuilt/remanufactured tranny instead of an unknown junkyard one, but I don't even know which model it is to start looking for another one. I looked on the case and found a sticker with these numbers. PM E87A PG 919233. Can anyone tell me what it is, and maybe where to find another one?
