While it is true that more black came out with the ATF by doing a flush, I never recommend it or do it.

It takes one spec of dirt to cause a spool valve to stick and cause a problem such as poor or no clutch engagement.. Then the slipping clutches burn and its down hill from there.

It is okay to let what ever accumalate in crevices where they do no harm..

Mercedes torque converters can be drained as well making for a better than usual ATF and filter maintenance.
