I have heard everything from "never touch the tranny fluid" to "perform a full flush" to just keep it topped off at proper levels.

I want to perform the best possible preventive maintenance I can. What is the best way to do it and can I do it myself? I saw a youtube video that said the safest way is to run the car hot in many gears, then drain, then top off with honda trans fluid, then repeat procedure 2x more.

Any suggestions??? thanks

That's the correct procedure.
 
There is a Honda service news article that outlines the procedure and works well. I've posted a link to it here at least a couple of times.

Would you change your oil a 2 qts at a time? Its no different.

Line off fluid exchange will provide the best results.
Very simple and easy to do on your car.

There is no flush involved with this procedure its simply letting the transmissions internal oil pump do the work for you.
We do this all the time on Honda's and never had any problems.

Can you explain this? I am a novice. Seriously, if you do not mind. Thanks

Here's a youtube vid that shows how on the previous gen Accord.
 
I would recommend the above U tube video. I did 3x drain & fill on my 08 accord and 04 MDX. I did the above U Tube way on my 05 Camry 6 XLE. The next time I do the Honda's, I will use the U Tube way.

Also, I used to have 1992 Lexus LS400 and I used the U Tube process 2 times until I sold the car at 300k miles to a friend. He's still driving it.

I like the cooler line flush method, it's easy and clean.
but i have a question that may be interested to the OP; I used the cooler line flush method on my 2009 MDX few month ago, and notice the unit only pump out some 4-5qt of dirty ATF out of total capacity of 9qt. somewhere betwen 4 and 5qt, the fluid start to look and smell fresh. I thought the cooler line would at least push out 90% of old fluid. anyone know percentages of old fluid would come out from cooler line flush on Honda AT?
 
I like the cooler line method, but it can get very messy very easily if anything goes funny. Drain and fill at a regular interval will probably keep the fluid fairly clean, after a complete fluid exchange on a neglected unit.

One thing I'm never sure of, how do these transmissions get so filthy. In the youtube video, it was black. I've done transmission fluid changes on a Honda with 60k and GM units with 110k and the fluid still looked fairly red - nothing like the "sludge" in that video. That's a little frightening.
 
ATF naturally darkens with age plus the worn clutch material is black.
 
The cooling line method takes much less ATF to get to 90% replacement. Drain and refill leaves 60% old fluid inside each time, so multiple drain/refills are needed, requiring twice as much ATF purchased and disposed of.
My 2000 Honda holds about 6.5 quarts. Pumping 6 quarts thru the cooling line gets nearly a complete change. It would require 4 drain/refills to get to 90% new, requiring 12 quarts new ATF.
