Just reviewing the manual for Odyssey :

"• Do not charge batteries if the temperature is above 104°F (40°C)."
... and considering some...
If you're going to pay a dealer to do the service then I would follow their recommendation (good or bad). If you don't agree with their decision then find someone else.
If the fluid hasn't been changed before now then most of the wear damage has already been done. I would do three drains now...
Are there magnets on the drain plugs? ... are there drain plugs?!?
I would definitely do three drains on those units and then again after a year. Add magnets if you can.
Thanks for the update. Let us know how it goes after some more miles on it.
If you really want to know then find a lab to test the fluid, do one now and then follow their lead. Otherwise, check your manual and follow the "Severe" service recommendations.
I'm 1/3 into my 2nd OCI (10k km, 6k miles) of VRP and the oil level is bang on. Will try to check it again at the 2/3 mark. So far so good.

I've used Valvoline MaxLife ATF is dozens of transmissions over the decades and have experienced no issues of concern. In the 2014 F150 I used a generic brand Multi-ATF from Canadian Tire (Motomaster, made by Shell I think?) and did five drain & fills after pulling the pan and cleaning the...
Thanks for the write up, I have an 2010 MR18DE with 140k that could use some work soon. So far it's running well on OE sparkplugs and it's 2nd OCI of Valvoline Restore and Protect. Fingers crossed.
OEM fluid is absolutely NOT required or desirable unless it is a "buy it now" deal. The transmissions are sensitive to fluid that is dirty, worn and overheated, not to the brand / label. Keep those magnets clean and monitor your temperatures.
We have a similar transmission on a 2014 F150. Did you check for service bulletins and have you had the pan off for cleaning? The magnets do most of the important filtering and Ford added extra magnets because of the trouble they were having. Regardless of how many magnets are in the...
A slow-change would be to do a drain & fill at each engine oil change. For some people that's once a year. Regardless, you should drop the pan for inspection and cleaning the magnets. The magnets do the majority of the important filtering and they loose effectiveness as they load up.
Stallion has a several products for ATV, Aircraft and road vehicles. So far I'm satisfied with the product I used (Phantom Farm).

That sounds similar to what I just tried.

Does not cure, harden or freeze. I bought it for a cheap tire on a tractor cart that was cracked all over the tread (dry rot). I only noticed after I tried using it that...
