I changed the fluid and filter a few months ago and have driven 500+ miles
since then without incident. And this transmission was installed new at
200Kmi, and now it has 288Kmi. Time to tow it in.

If it's a big leak the most common cause is from the pan bolts being
overtightened (deforming the pan) and the gasket will no longer seal and
may split. With older transmissions (15+ years old) the valve that
prevents fluid in the torque converter may leak and allow it to drain
back into the pan. The pan can't hold this additional couple of liters
of fluid and so will overflow out the top vent. This usually takes
several days to leak down so if you drive the car daily it's seldom a
problem. There are several other seals that can leak and of course there
is the front pump seal that commonly fails in 15-20 year old 722.3
series transmissions. The transmission MUST be pulled to service the
front pump seal.
