Ports on side of transmission? 1990 325i 5-speed

[E30godz]

I was under the car yesterday removing the exhaust and inspecting the transmission when i noticed two threaded holes on the drivers side of the trans. What are these ports for? If i had to guess i would say a transmission cooler? Anyone know what im talking about? There was also nothing threaded into these holes...

I'm not sure if I totally follow. You said there's two threaded ports.....is something screwed into these (a la plugs) or just holes that are exposing the inside of the trans? I have the same gearbox but never noticed these before. As for a transmission cooler....I don't think something like that was ever offered. It would make sense if this were an E30 M3 gearbox where its bloodlines closely resemble its racing counterpart.

well im not sure if they are exposing the inards because its dark inside them heh. As i said theirs nothing threaded into them., it looks like there should be! Its a very fine thread too
