Question on AT flush

[weatherwatcher]

I have an 06 Honda Accord EX V-6 with 59,000 miles. I am getting ready to do a drain and fill on the automatic transmission. My question is, when I do the drain and fill, should I just do the procedure once or should I do it three times to try and remove as much of the old fluid as possible. I saw the DIY thread on this, and it appears it was only done once, but I believe that his car had less miles than mine.

Great website, I just found it and I have found loads of useful information.
