Maybe a pro can add some light to this issue as well. but it is my understanding that you should never perform a "engine" or "tranny" flush. the reason being the flushing agent will contaminate the oil/fluid causing premature failure to the componet. The owner should only drain, change filters, and refill.... NOT FLUSH
I know this is fact on my fathers Titan... is this true for fords/all vehicals?
it makes sense to me though
