Transmission vent leaking

I need some help people.

1994 BMW 540i transmission vent is leaking fluid.
It has no codes, shifts fine but it is leaking fluid from the vent tube.

I took it apart and could find nothing wrong except the "O" rings on the electrical connector. Put it back together and back in the car and it is doing the same thing. Any help would be GREAT.

Any moisture that is in the trans (possibly from pressure washing or even condensation or contaminated refill) can cause the fluid to escape through the vent.
