I have a Subaru Legacy B4 2000 Blitzen Edition, and it's 5spd it's almost dead.. and the code it has it's TY754VBAAA and i got a friend that has one, none using, but the code says TY752VBAAA, i was searching on internet about them, but i just find a difference in the F.D. mine has 4.444 and the otehr has 4.111, i wanted to know if I can put my friend's one in my car, if it fits?... , without doing any damage.

Your rear differential needs to match otherwise you will do damage.

I know, iI wanted to know, if the one I have for the TY754VBAAA will match with the TY752VBAAA transmission.
