All you need is Honda ATF-Z1 ($6-8/qt, 3 qts/change).
just did it and bought 3 qts
then realized that you need 9 quarts to actually do the drain and fill 3 times lol.
i thought it was 3 qts for 3 drain and fills

Why not take that 9 quarts pour them all into a bucket... get a second drain bucket.
Disconect the hose from output side of tranny cooler put hose in new fluid bucket, put another hose on tranny cooler going into waste drain bucket. Start car make cycling in new and expelling old. Saves all kinds of time as long as you watch the level of you new fluid to avoid running dry.
I may be wrong but it makes sense to me. Just a thought Ive had for doing mine when the time comes.
sorry...was thinking about this the other day and saw this post
I had the same thought...but which hose is the input? Which is the output? I couldn't find good enough info to take the chance and the wifes "new" accord isn't something I'm gonna play withmaybe if it were my DD. Plus there's just something about that idea that makes me uncomfortable...well for one no one does it like that...ever that I know of. But in theory it very well may work.
The most important piece of info is that this really isn't needed and won't give you better results than a 3x d&f. Keeping debris out of the "clean" bucket would be a hassle, you don't want anything, not even small pieces of lint, getting into the transmission. Any way it's just not necessary.
But we are all different...I'll buy a $13 rebuild kit for a part that cost $26 new. A little hassle is worth it for me most times. So if it's worth it to you to do it and you just want to find out then by all means post up your results/methods...why not have the info out there? Depending on the success I might give it a whirl...but not until I see someone else do it and succeed![]()
Your Honda fluid has a very specific set of friction modifiers that slow the wear on the clutch cones (some are made of paper).
Newer fluid doesn't mean better fluid in every case.

For example, in a few Saturn Ion automatics, if you accidentally fill them with Dexron III, drain it out without starting the car, fill it with the correct stuff, the tranny is junk within 5 minutes. True story from my Saturn tech buddy![]()
