Update on my wonderful situation.
Just picked the car up today, again.
When I asked what they did to it the guy told me they put a re-manned tranny in it.(Exactly what they said last time) when I pointed this out he said oh no he must have 'mis-spoken' -we just replaced the seals etc. last time.
I got to speak to Joe (Service Mgr.) today, and he was actually more straightforward and honest than anyone else i've dealt with. I did explain that if this didnt hold up I would be expecting a brand new tranny on the next 'visit'. The car seems to run better, tranny is shifting good but there are some occasional tranny noises that are worrying me a little, plus a tinny engine sound between 4.5k/rpm and 5k/rpm.
I'm calling them back on monday because under WOT the car will not hold full boost to save its life, it fluctuates heavily and constantly between 7.5 and 14lbs. and you can definately feel it under acceleration. I believe there is a problem with the downpipe that should have been addressed at goldstein ages ago but wasnt..go figure.

After I get this taken care of and the car hopefully runs at least as well as when I bought it i'm going out looking for a new legacy (per the wife). Want a GT, will probably end up with a lower model (no boost)

But anything to get out of this beaten old rex...right about now i'd be willing to trade for the forester 'rental' they put me in this week.....
Thanks for all the responses.
