I was going to replace the transmission fluid on my 2000 and 1996 Accords, and looked at the owners manuals and it reads every 90k.
The last time I changed the fluid it was about 33k on the 2000 and 50k on the 1996, but I did the change by loosening the plug in each pan and draining then filled them both up with Honda ATV fluid.

After reading more it should have been 3 drain and fill procedures, so I thought to do it better and start fresh on each.
I saw this video and wondered if this is the correct procedure in a fluid flush?

Questions:

1. Is it fine to just drain via the pan plug only and fill or is disconnecting the cooler line needed?
2. How long to drive it around before draining each time?
3. Is the procedure to drain and fill again like this until 3 total flushes have happened?
4. ls, the use of Dextron III for the first few flushes and finishing with the Honda ATV fluid thats more expensive a no no?

 

I wouldn't bother doing what he does in the video. Just do the 3 drain and fills. Do a drain and fill, drive it for 10-15 minutes, drain and fill again, drive, drain and fill.

and do not put anything other than honda atf in your transmission.

 

I bought a 2011 Pilot about 1.5 years ago. I heard a lot about 1st Gen Pilot and MDX tranny failures, or even V6 accord for that matter, so I read carefully about peoples experiences and recommendations for maintenance.

At least for the J series autos, they do not like to be flushed. I would do straight drain and refill, just one time. If you see fluid that's excessively dirty or burned, you can do it again in a few thousand miles. DO NOT use anything but Honda ATF-Z1.

 

That video gives me Forest Whitaker eye.
Purpose of the drain is to get all the junk that sits in the sump out.
Yup, you want to drain and refill x3.
Draining pulls all the gunk and junk from out of the sump and away from the pickup.
No need to disconnect the cooler lines.
Charge each circuit for a few seconds, verify the sump is full, then drive it around enough to run it through all the gears. Don't forget reverse.
Yup, drain, refill, drive around x 3
For the 90-97 H4A DIII is more than adequate. I have three FSMs, from these generations. Honda ATF or DII was recommended, only the owners manual states to only use DII temporarily.
DIII will be fine for draining out and if you prefer to have Honda ATF in it, that is fine as well.
DIII was upgraded so much over the years that its final form was actually DIV but due to some internal conflicts at GM it just became the last DIII iteration. 'DIV' name never came to market.
DV was not used, most likely to avoid confusion with Mercon V
DVI is the latest Dexron fluid.

 

Scotty Kilmer is a popular and informative mechanic. He has a video on just this.

Just to 6:08 for his warning NOT to flush a transmission.
