I plan to tackle mine before it goes south, hopefully it won't require as much in hard parts that way. However, mine is a '94 which supposedly has all the updates in place.
If I were you I'd probably get the Subaru (remanufactured for them - I've been trying to figure out who actually does it but haven't had much luck. I have found where they send the cores, but that doesn't help finding a deal on a reman unit.) They appear to not have the problems that many others have had when rebuilt by local shops. L10 is probably o.k., I just have a hard time parting with that kind of jack for basically the same unit. (no flames req'd.
)
I have an old customer from MO that was talking about moving back to Denver/Greely. He was a Subaru tech and used to work for Fred Emich. Name is Jack Redman and he used to rebuild quite a few Subie trannys when I knew him. Maybe worth your time to see if he's around. If you're planning on keeping it for a while though that 2 year warranty is pretty tempting...
