Good guess Nitrogen but not this time. Got my six back today and the leak was from a cracked tranny pan - dealer replaced pan, seals, etc. under CPO. Since I had her in the shop a few weeks ago for an unrelated oil leak fixed by replacing the vacuum pump/seals, my SA even waived the $50 CPO fee. So, I'm a happy camper in that the only cost was tippng my SA.
Now, if I can just get the rest of the seals/gaskets to fail in the next 7 months remaining under CPO, then I will be set for another couple of years...
