Just make sure you replace the converter no matter what you do... reused or "flushed" converters are pretty much the #1 reason for repeat failures.
And flush the ever living hell out of your trans cooler lines as well... some guys even go so far to replace the cooler itself when a trans fails... though I think that has more to do with what kind of cooler it is... the ones w/ the one "S" tube going back and forth with fins across should be pretty easy to flush out... the ones that have a ****load of passageways I would consider replacing.
