so I've found one of the transmission leaks (85 300D) is the modulator oring.
I have a few questions that maybe someone whom has been here before can help me with.

How does the modulator come out? (unscrew it?)

do I need to re-set the pressure, even If I am just replacing the oring and using the same modulator?

will I need a new "pin"?

thanks
