Ya, I had the same reaction when I first heard this...and maybe I'm carrying on a myth.
I have heard of people using a T-Tech machine -some bring a bunch of Honda ATF-Z1 to avoid the typical Lube Control mix. If its passive then maybe my statement isn't correct.
I have a 02 ody, I first learned that the DIYer's were using a 3-4 drain/fill at Odyclub.com, claiming that this is what Honda recommends. Being skeptical, I looked in a Honda shop manual and found the same info. Since my 02 at the time was under warranty, I called my dealer to inquire about a flush, they told me that they had a 3 drain/fill procedure and no flush machine. They told me if I went to a third party for a machine flush, Honda would not stand behind the warranty on the AT. I asked why, and they told me that some machines create pressures and flows not typical of normal operation that could dislodge the screens. I have since seen posts with simlar statements, Fact or Myth, I'll let someoneelse experiment. It wouldn't be the first time a dealer myth circled the country...BUT Honda is different, no serviceable filter, no pan, goofy Z1 fluid - so I'm not convinced that flushs that are perfectly safe for every other auto are safe for a Honda.
The last time I was at jiffy lube (nearly 10 years ago) they told me their flush machine used a vaccum - which I declined since back then I always single filled and drained at 10-15k. I'm back to this interval with my ody now that clutch pack shreds seem involved with the 02 AT premature deaths.
I also have a 91 honda that was specd for DII. When DII disappeared, I tried DIII - bad shifts once it got to near 100% DIII. I tried Z1 (4 fill/drains) - still bad shifts. I tried 50/50 mix of DIII/Z1 - returned the performance back to DII days - go figure.
