    Hi guys, so I just got my first subaru. It's a 2.5 2000 outback with a bad front diff. I was just wonder what subarus share the same trans. It's an automatic. Thanks

    Look at the top of the transmission and get the number. I think you can use any legacy or outback auto 2000-2003. Maybe even a Forester's. Have to match up the rear gear ratio.

    Or swap out the rear diff and everything. Sometimes that is just easier (and cheaper) than finding the correct rear gear ratio transmission !

    So my Trans has the code starting with tz1a. I just found an 05 forester tranny with the code starting with tz1b. Does anyone know if this will work. I read the 3rd and 4th number have to with distance between gears.

    The following is from post #5 of this thread...might help some: http://www.subaruoutback.org/forums/66-problems-maintenance/94225-transmission-compatability.html


    For the 2nd gen (BD/BG):

    example code = TY752VBCAA
    Breakdown:
    T = Transmission symbol
    (T - Transmission)

    Y = Transmission associated classification
    (A - 2WD AT)
    (M - 2WD MT)
    (Y - 4WD AT)
    (Z - 4WD AT)

    75 = Transmission type series classification
    (75 - MT [75mm])
    (10 - AT [108mm])

    2 = Car body series
    (2 - Legacy series)

    V = Standard transmission spec classification
    (A - 2WD AT [TA102])
    (R - 2WD MT [TM752])
    (V - ViS-C center diff 4WD [TY752])
    (Y - VTD MP-T center diff 4WD 4AT [TZ102])
    (Z - MP-T center diff 4WD 4AT [TZ102])
    (X - ViS-C center diff 4WD D/R [TY752])

    B = Correlating engine classification
    (B - 2.0L DOHC MPi turbo)
    (D - 2.0L DOHC MPi NA)
    (S - 2.0L SOHC MPi NA)
    (W - 1.8L SOHC MPi NA)
    (1 - 2.5L DOHC MPi NA)

    C = Yearly improvment/design change classification
    (Starts with 'A' and subsequently 'B', 'C', etc.)

    A = Shows change in specification in transmission body
    ('A', 'B', 'C', etc.)

    A = Doesn't change based on vehicle engine or body

    Mine is Tz1a4zcaba. The forester has a tz1b5lcxaa. There's plenty of differences in the code but I have no idea if that translates to it not plugging in and working. I've been reading a lot of contradicting info on the internet. Some people say any phase 2 Trans is the same and will work. Some say the first 5 have to match. Confused. Does the second to last letter tell me it won't work? All it says is "shows change in specification of transmission body." Does that mean it's going to be way different, or is that just something like a moved sensor? Thanks
