the a4ld is not junk. you just need to make sure you get it rebuilt by a reputable trans. mechanic. not some out of know where, backyard, cheapo guy. it might cost more, but it'll be better than taking it back and having it fixed every 3-6 months.
if you want it done good and cheap, it ain't gonna be fast. if you want it done good and fast, it ain't gonna be cheap. it you want it done fast and cheap, it ain't gonna be good.
I suggest taking your trans. to a dealership or a trans. shop. no one else.
