Thanks, engatwork
it is somewhat courious that all these leaks appear, while the pan that I suspected to leak is supposed to be fine.

You hit the option I didn't mention, i.e. have the front seal fixed for free and then worry about the leaks later. Either have someone else do it or live with it.

Any other opinions, please. How many are driving around in a somewhat leaky transmission?

Thanks again.
