thanks again evowrx its a 4.444 ratio would I be rite in saying a outback 2.5l same year 98 has the same ratio diff

Thanks for that evowrx I have just read all of it and im still confused as some people say the ratio should be 4.111 and some say it should be 4.444 so which is it lol

have put the trans code on the net and cant find anything about its ratio all I can find is ratio for manual trans.

yes I could also take the back plate of the diff and count the teath etc and work it out that way or by the numbers stamped on it. The problem is im not sure if its the correct diff for the car I need to know what diff its suppose to have with the transmission its got.

Hello all hows things going. I have a 1998 legacy twin turbo auto and its the cross over b4 shape BH if I remember the chassis code The question is does anyone know what the rear diff ratio is. I have pulled the diff from the car and it has in white paint BC written on top. I have searched the web and can not find a definite answer to what it is. also im just wondering if it is the correct diff. Transmission code is TV1A4YBAAA have looked all over the diff and cant find any code stamped or the foil sticker. My next question is what other auto legacys have the same diff. A Big thank you in advance

need to know a bit more because I know there is compression differences so really need to know which block is going to be suitable with the ecu etc

mines the cross over the b4 shape bh I believe

Hello all again. I have a new problem that's started in my year 1998 twin turbo legacy auto. Ok hear we go I replaced the auto trans with another one exactly the same what a mission it was as well. Since doing the change I've had a few issues not with the trans but with the old girl just cutting out hears a couple of things that's happened. 1 after 2 weeks i drove to the shops and came back checked fluids in trans while she was running and went to put car in reverse and all the dash lights just came on and it started beeping at me and then it died it done this a few times then came rite no more issues for a week until i took my boy to school and then on the way home pulled up at lights to a stop and it just died on me after locking and unlocking the car and playing with the alarm immobiliser i managed to get it started and of I went its done it a couple of times. Have checked all the wiring plugs etc and i am stumped. She has a turbo timer and uniden alarm immobiliser could any of these be the issue or something else. thanks in advance for any help

Hello all need some information please. I have a Subaru legacy gt twin turbo auto year 1998. My trans is just about to kick itself in the nuts and I need to know what trans are compatible. The trans it has got at the moment is trans code TV1A4YBAAA is there any other transmissions that are compatible or nearest to it or can I put any turbo trans from about the same year in and just change the rear diff and trans computer and if there is a compatible one what would be its trans code. Thanks very much in advance
