I have a burning question. Has anyone switched to Amsoil ATF. I live Amsoil products they never disappoint. But I haven't been able to find anywhere if it be put in instead of the Honda type 2.0 for the 10spd transmission.

The reason why Honda, Toyota, etc have their own fluids is because they can control the formula.
Penzoil will randomly change the formula for the "green" coolant.
Mobil 1 also does the same for ATF fluids.
Let's say you are Honda and are using Havoline radiator fluid in your vehicles. Havoline announces that the fluid will be changing for better heat transfer in higher temperatures. If course, Havoline will not say what has changed. So, Honda will have to redo an entire series of tests to qualify the new radiatior fluid. We are talking chemical compatibility on every part of the engine the is touched by coolant: hoses, gaskets, plastic parts. Heat transfer testing will need to completed. Probably some sort of extreme life test of the coolant.
Same scenario, except for transmission fluid. In addition to chemical compatibility, Honda needs to retest all affected transmissions. We are talking requalifying everything through life test, durability, load test, This will easily cost tens of millions of dollars per affected transmission.
Coming from 25+ years of new product design and testing, this would be my best guess for OEM specific fluids. And yes, I had to completely retest products due to fluid formula changes. This can take months or even years, depending on how long the life test lasts.
So, circling back to the Amsoil question. If the OP is willing to gamble with a $7000 transmission, then go right ahead and use Amsoil fluids. Surely, the Amsoil engineers are way smarter than the Honda engineers. Keep in mind that Honda has been testing the 10 speed transmission with their ATF fluid since day zero. If any issues came up, Honda either changed the ATF formula or redesigned the transmission to fix the issue.
Ok, I decided to spend a few minutes on Amzoil's website. Seriously, this is how they test their fluids. The Honda OEM fluid has also delivered outstanding protection in my CRV, because the transmission is running strong at 130K miles.

- CVT Fluid
AMSOIL delivers outstanding protection in severe service.
AMSOIL CVT Fluid was installed in four Las Vegas taxis, each driven 100,000 miles. As shown in the belt photos below, AMSOIL CVT Fluid delivered outstanding protection in severe-service conditions.

There can be but most times, it’s often money related.
I have tested and has been using the Amsoil CVT fluid for my Toyota and nissans notoriously well known CVT and i can confirm that it has been running better than ever before. I am well over 200k on that car with original motor and transmission. So I do trust the brand and their products.
The reason I have decided to switch to Amsoil ATF for my odyssey is that it has already started hard shifting and stuttering at only 95k using the Honda ATF drained and filled at 40k then 80k. So yea OEM fluids sucks IMO.
i will definitely update this thread after I make the switch and give you the results who are interested.

This is not the time to be changing fluids if you already are having problems. Changing into another fluid will not improve anything, but worsen the problems. I do not think anyone here on this ODY Forum would agree with what you are attempting to "fix". If I was still working as a mechanic, I would tell you should not change the fluid, however possibly do a diagnostic check for possible reported problems, and see if you have all current software upgrades to help your ODY 10-speed transmission. If your transmission is doing this consistently, they should be able to find the problem, but not always. I believe Amsoil would tell you the same thing. If the problem exist now, changing the fluid will not improve your transmission.

I did a break in drain and fill on a '23 using amsoil (red cap/multi vehicle IIRC) around 6-8k miles ago. Zero issues. I too am an amsoil fan.
I had similar experiences with my Altima CVT and switching it to Amsoil CVT fluid fixed it and made it smoother than it was ever before. So yea with that experience I think i would do the switch even though it may not fix the issue but im confident enough that it won't break it.
Wow great to hear that!
Send an email to Amsoil & ask them. They will tell you. I use it in my 2011 Ody and cvt fluid & signature oil in my CRV.

I’m less concerned if Amsoil says it’s compatible. I’m less concerned in the sense that it will not damage the transmission. Quality shifting is to be seen. A 3x may be needed, so if one D&F didn’t give positive results, don’t be afraid to double down.
No fear. 😅

What if you used the cheapest or the most expensive lubricant you could find and it "didn't dissapoint". Because your engine/transmission is still working does not prove the lubricant is OK. Can we simply use what's called out in the owners manual-- and link to the specs called out there to what's on the container of whatever you buy. Lets stop this endless go nowhere discussion.

I am answering the man's question. IF his proposed Lub links to the specs per the lub called out in the owners manual then you can use it. If it does not then you cannot use it. That was what he asked. The dealership frankly does not know what lub you used -- Honda or something else. Actually they don't care. They get paid to fix the Trans under warranty as well as out of warranty.
1.). The specs in the owner's manual are recommendations, not requirements. They cannot legally require you to use something without providing said something. Since they aren't going to do that for free, they cannot word it as required.
2.) If you use something else than what's recommended, the manufacturer has to prove what you used is what caused the issue, not just that you "used" something other than recommended.
3.) What the crap is going on with your post for the Bing map?
Bot?
Thanks for coming back with updates. Just to confirm, you are using the red cap Multi-Vehicle ATF?
Yes, the red cap bottle mutli-vehicle
PXMA (10 speed) transmission Amsoil recommended fluid is indeed red cap fluid.

Strange, Type 2 for the 10-speed is listed in both Amsoil ATF compatibility lists:
Both are good ATF's, just that Multi-Vehicle has a slightly higher viscosity than Fuel-Efficient.
