I have a '99 forester thats been leaking trany fluid. I had a mechanic friend look at it and he couldn't find any obvious leak. Another mechanic friend has a '98 impreza automatic transmission (tz102za3ba-g9 and 844424), and I want to put it in my forester. I couldn't find anything specifically about the parts I have, but I read/heard I might have trouble with the rear differential, electronics (I can splice, shouldn't be a problem), ratios, and some other part I dont remember. Is this transmission compatible with my forester? If not, what do I need to do to get it to work?
