There are plenty of posts on this very subject, some very complete
with needed tools etc.. Just search on 300D transmission.

Later when I have more time I'll try and dig up a few.

You should check into B2 piston too (again - use search).

If you see fluid leaking from the bell housing with the engine off, it’s the pump rubber o-ring that is
Leaking, Also change the front seal and bushing if you transmission has one. I would drive that car around for a while, to make sure it was low fluid, not shifting, before you remove the transmission.
