So I have a 1995 legacy wagon 2.2, its pretty plain as day that my tranny is going out. Goes into 4th but pops out on acceleration. It also goes into 3rd and is fine when accelerating but as soon as I let off it pops out.

My question is. would a 1999 2.5rs tranny or any impreza tranny fit? If so what else would I need in order to get it to work?

Thanks in advance. Sorry if this question has been asked before.
