Drain/fill or Flush

I know this topic have been discussed many times but i am still confused. My TL is now at 37000 miles. Should I replace the ATF by doing the drain/fill, Flushed method or take it to one of those shop that have a machine that pump the old oil out and new one in.
thanks.

Drain/fill: The Acura recommended 1x drain/fill procedure will only replace only 43% of the tranny fluid (3 out of 7 liters in the tranny.) The 3x drain/fill technique will replace 84% of the tranny fluid (special ed math not shown).

Not specific to Honda/Acura, cleaning magnets is a MUST for proper tranny maintenance to any car manufacturer. Some shops using a machine method does not remove and clean off the drain plug magnet. With the drain and fill method, cleaning the plug only takes a few extra seconds.
