Anyone know the exact amount of fluid to put back into the 722.6 transmission (on a '00 c280 if it makes a difference) after a pan removal and filter change?

I'm thinking it would be more than a "drain and fill" since all of the trans services I've done on other cars, more fluid comes out when you remove the filter.

Anyway, if anyone knows from experience, I'd like to hear from you.
