Well Cap,
Do nothing an pray a lot has merit. You really are a lucky guy to find such a motor.
Unlikely the Little Old Lady [unless she's from Pasadena!
] has driven the car hard or pressurised the weak points.
Your miles are too low to expect trouble with the tranny. Two things you ought to do, three maybe.
Replace the tranny oil with good quality Redline synth. While doing this, check if an inline filter has been fitted. It may not have been, and some say you shouldn't bother, but it is likely to save you a lot of trouble for little expense, and will do NO harm. Flush the system while changing the ATF. I would advise letting the tranny shop do it, and instruct them NOT to reverse flush under pain of death.
No 2 job, also while changing the ATF, fit a secondary cooler. The 19000 lbs Supercooler is the one to use, fits easily between the rad and the condenser. Use in parallel or series with the stock rad cooler. Do NOT take the rad cooler out of the equation, particularly if you live in a cold place. It lets the oil warm up quicker to operating temp. It is only poor at keeping cool enough up hills, driving hard, heavy traffic etc.
Change the ATF once a year with this set-up, your box will last and last.
No 3 job. The wheel bearings. If you can't hear the rears growling or grumbling, they are OK. You should repack the 4 bearings with the special grease for peace of mind. It is part of the service procedure, and should be done, not sure if everybody does this. Click onto the Subaru of America site and find the End Wrench article showing how to do it.
That's about it. Best of luck with it man.
Joe
