325e 1986 transmission leaking

hey guys i have a 325e 1986 and my tranny oil started leaking when i got on the freeway. so i got off and did not drive it for a couple of days not i put more tranny oil in and it wont leak no more any idea what this could be i tried finding the leak but i could not find anything that kept leaking

Automatic or 5 speed? I'm guessing manual 5 speed. How did you discover it was leaking if you were driving?

Not leaking now? It's probably all leaked out!

I still wouldn't drive it. Untill the seals were replaced. Don't want to have to put a whole new tranny in.

its automatic i got on the freeway and i saw a lil bit of smoke pulled over and i saw it was leaking i put more tranny fluid and it has nt leaked it out

Inspect tranny pan gasket and lines/cooler. Also driveshaft seal. Check tranny fluid level with engine running in park

BMW = British Motor Works = It's gotta leak

Sometimes seals dry out & a lot of oils got "seal swell" additives in.
This can explain why something stops leaking.
I am a paranoid type of guy, knowing that this leak will reapear 500 miles from home in the middle of nowhere whilst it is 120 F in the non-existent shade
Clean your motor, gearbox & underbody thoroughly, because the wind & engine fan have cruel ways to blow oil into directions where there is no leak
Then find your leak & fix it

I HATE leaking cars & humans
