240 Transmission keep leaking

[smeha]

Long story very short.
Gave to a shop to drop and reseal trans AW70. Was leaking only in rear seal and rear trans.
Shop overfilled ATF, had to partially reseal again after it purged ATF all over.
Afrer few days it leaked from trans pan and tail shaft - repeat 3 times. Finally shop sealed it, no leaks.
After a month, yesterday it started leaking againg around rear trans pan.
Trans case ventilation was air blown at some point in between, in order to make sure it doesn't over pressure.
Thoughts?

How did the shop seal it the second time?

The cork gasket is kinda fiddly to put on so they might of damaged it/not have it seated correctly.

Have you checked to make sure the bolts are done up also - I had to re-do mine 3 times before they stopped vibrating loose (no toque wrench small enough)

I will check bolts.

It means the hole on top of transmission case was cleaned, had i suspicion that it wasn't ventilated properly and over pressurized.
