Rub, I was right about the leak being from the pan gasket. You were spot on about the gasket sealers. They said the sealer was failing and they needed to reseal it with something else. It will be covered under the regular engine/drivetrain warranty.
Since it happened to yours (different repair) and other cars were recalled for similar issues (not the pan gasket), I think we can assume that a lot of Subarus are going to be leaking trans fluid from somewhere eventually.
All of them I suspect..
This may be part of the reason why Subaru announced a decrease in their forecast profits for the current year. IIRC, they are spending $500M or so to maintain quality compliance standards or for those of us who use small words, make sure it doesn't break and leaves right from the factory we don't have to go through this fiasco with our customers.
I think this is exactly why they have the 10/100 policy in place. They will all leak at some point.
