Pulled the pan this morning... no debris... no sludge...

Removed the filter... no clumps... looks used/new (replaced it ~1,000 miles ago).

I've Googled and Googled... but am findoing no 'vent' or 'breather' for the transmission in the event of overheating. Does it exist on the 98 Tip? Where is it?

Clearly there was a failure point... but I'm not finding it. I've had the lights under and above... the cranny-mirror... and don't see anything obvious. Absent a troubleshooting suggestion or recommendation I'm considering just buttoning it up... filling it up... testing to see if it moves.

Nothing mixed with the oil or coolant. Engine starts.

Given the low miles on the filter would the brain trust recommend reusing the OEM filter or purchase a new one?

In advance, thank you.

Here's the transmission vent on a 2001 Tiptronic. This particular car is a little non-standard, but the vent line on your 98 should terminate near the back of the engine behind the intake.

Thank you, 78, I'll take a look this morning.

Have a good day.

Filled the trans pan... plugged it... started it up... and this is from where the leak is coming.

After I identified exactly from where the leak is coming I restarted the car for a moment putting it into drive. The wheel spun, in idle. I'm assuming this is a good sign for the TC.

It appears I'll be taking it to an indi, unless someone believes this is a carport-doable job for someone with zero AT experience.

Advice welcomed, thank you.

That will be the transmission input shaft seal. It does not require trans tear down to replace but the trans will have to be removed.

Thank you, 911. So... just remove the tranny... replace the seal... button it back up?

Duke's light-hearted sarcasm made me wonder if it might be worth your while to replace the IMS while you're in there. You never know, this may turn out to be a blessing in disguise if your IMS happens to be on it's way.

I don't intend on doing the IMS as a standalone, but if for some reason I had to pull the tranny I'd definitely do it while I was there. Just my 2 cents.
