compatible with DW-1 ATF
Well, his fluid is maybe compatible in some respects (e.g. viscosity?). But it clearly did not work in your Ody.

Lesson learned all around.

Thanks for the update. Do post a pic when you can.

I have been very careful with the van since the beginning (Muzzled, ATF change every oil change). Everything works great so far. Today I changed ATF and the van immediately started slipping after that. As I speed up, I can see the RPM moves up and down as if it is gear hunting but I think it's just compensating for the slippage. Sometimes, letting go of the brake will not move the van and I have to give it gas >1-1.5K RPM to actually move it.

The van is 2017, 67K km.

I used to do all my ATF change, this is the only time I did it at the garage. I guess that was the mistake??? I'm thinking of just order some ATF and do a 3 drain-fill cycles to see if it helps. Is this a good idea. It has been running perfectly before the ATF change so I don't think there is damage to it.

Thanks for your inputs.
Try disconnecting the battery for a few hours.
Try driving again.

It clearly says on the label that it is compatible with DW-1 ATF.
Sometimes it's all in the definition of terms. This could simply mean that you won't get a violent chemical reaction when you mix the two. Unlike sulfuric acid and water,

Instead of waiting a few hours, just touch the cables together for a second or two AFTER you disconnect the Neg from the battery, of course, Otherwise, a possible explosion and/or bad acid burn.
This will drain the capacitors and that is the same thing that is what is done by leaving it disconnected for a long time.
Leaving it disconnected is somewhat safer as long as you disconnect the Neg. :)

On our 15 odyssey the cables were not long enough to touch, so I just left em for a few hours.

No jumper cable, or 12 inch long piece of wire or copper pipe or aluminum or...any conductor?

Electrically connecting the two cables resolves issues that do not go away with just disconnecting.

Pressing the brake pedal does it with 0 risk...

0dyfamily. So I bought a 2015 minivan with maybe one ATF change at around 80k miles. Now the van has 197k miles. The transmission is fine, maybe a little shaky around 30mph but nothing major. Do you recommend a change the ATF even if the color is brown?!?!!?
Yes ----do 3 drain and fills, go for a 5 min drive between each drain and fill.
I just did this to our 15 ex.......made a huge difference in shifting and acceleration.
I used maxlife atf, red jug.
3.5 quarts for each drain.
Refill through the dip stick tube. Easy peasy.....quicker and easier than an oil change.

Update. I went to see the mechanic today and he showed me the oil drum he used for the ATF. It clearly says on the label that it is compatible with DW-1 ATF.

I tried to take a picture but my kid played with the phone and changed it to 5sec timer.... let's just say that the resulting picture is rather uninteresting. I'll do it again next time.

He now stocks Honda DW-1, to be used at least for the Ody.

yeah let us know what it was... quite curious... I am running Maxlife Val 3x drain/fill now, then I had added Lubegard platinum (already had it), and not it is butter...

I will be installing a trans cooler and changing the external trans filter on my 6speed TE. I will also add a magfilter too

So, it's Verco's "one size fits all" ATF product.

I put my magnefine filter where the oem filer was. Easy peasy.

I managed to find the TDS on that APRIL ATF LV. It does not seem too far out of the ordinary, except that it has pretty thin viscosity at all measured temperatures.

It also says that it supports all of Honda's ATF DW-1 and ATF 3.0 and ATF 3.1 specifications.

However, the company says it is recommended for transmissions with 6 or more gears. They don't make any sort of tacit recommendation for supporting use in any older 5-speed designs.

They also say this: "... made from pure virgin base oil and APRIL NANO 1™ lubricant technology." In general, use of "nano" in lubricant ad copy refers to addition of very small boron-based, moly-based or tungsten-based particulates added to form a barrier layer on bearing surfaces (notably, shell-type bearings). You would not want that in a wet clutch system ... it would cause slippage.

However, that claim of using "APRIL NANO 1™ lubricant technology" might be just some sort of ad hype to cash in on the "NANO" craze. It could be that this APRIL ATF LV contains no added nano-sized particulates at all. This ATF is a proprietary recipe only known to the people at APRIL, so who really knows?

That APRIL ATF LV stuff is definitely a big drum of "transmission mystery sauce." 😕😕😕

Even though I don't use Honda ATF in my Odyssey (I used to tow a lot, and I did get slip on hot days with almost 3,000 lbs. on the drawbar using Honda ATF), I stick with brand names. AmSOil and Valvoline have been my "go to" brands.

If you do lots and lots and lots of purely low-stress highway miles without a trailer on the hitch (like 0.01% of us, like our own @John U does), or just regular Joe family hauler work like 99.98% of us do, Honda ATF DW-1 is fine. I'm in the 0.01% that has been known to beat a minivan transmission with towing duty.
