Our 2002 outback tranny went out (TZIA4ZCDBA-RM)...I found a good used one from a 2001 Impreza (TZIA2ZAEAA-WX)....I was told that they are the same tranny..but there are some differences...the oil lines are different and the torque converter bolt pattern is different too...now I wonder if anyone can tell me for sure that the diffirential gearing is the same by the numbers on them Thanks
