Question about Suzuki Swift (Geo Metro)

Sorry for posting this here, but there is no Suzuki autos group.

I was under my 3-cyl Geo with the engine running, trying to find a rattle
which I found was coming from the heat shield on a cad. converter. I
noticed air blowing under the 90-degree bend in the pipe that connects the
converter to the header. Since I had just patched a hole in this pipe (it
is new but had a hole in it from a bad welding job at the factory) I assumed
it was coming from the patch or another hole. I put my hand up to the
patch, fingers toward it, but I only felt the air blowing on the back of my
hand, as if it was blowing out of the holes in the bottom of the transaxle
instead of coming from the exhaust pipe.

Also, the blowing air did not smell like exhaust--and the radiator fan was
not running, so it wasn't coming down from there.

When I revved up the engine, the air blew proportionately harder, but I
could never figure out exactly where the air was coming from. It seemed
that whenever I tried to follow the air back to the source, I'd lose it.

Nut it did seem to be coming from one of the holes in the bottom of the
transaxle (it is automatic transmission). Three of those holes are
threaded, and one looks like some sort of breather or pry hole, though I'm
not sure, as I have no experience with trannies. But I thought I had at
least a vague idea of how they work, and nothing in my mental outline
included a provision for air blowing out the bottom.

Any suggestions?

that is the torque converter spining around and the air pressure changing
inside of the bellhousing

Ok. What I don't understand is, if the spinning torque converter can blow
air out of the tranny, then why isn't AT fluid pouring out those holes as
well?

Unfortunately, that engine is a very poorly made design
that is made for a Japanese type microcar instead of something
as heavy(?) as the Swift. That said, it's running properly.
