CVT drain and fill for K313

Bit confused--majority of posts and videos show a drain of 2L, if you pull the straw. But a few places mention 1.2L instead? Including this snip of the manual that someone here on Toyotanation was kind enough to post (link):

I'm getting ready to just do a D&F, the car may or may not have been driven hard before I got it at 46k (who knows, it was used), so I don't plan to do a filter (only at 50k). Unless if the oil comes out looking like tar, I figure, a few D&F's will ease my mind--it's going to live on the highway going forward. So I get it, measure what comes out, put that amount back in (and if I am so inclined, do the actual procedure to check, at the proper temperature).

But why 1.2L vs 2L? Again, K313 behind the 1.8L in a 2021 Corolla LE.

Also, am getting conflicting results for the fill crush washer, in one place it's listed 90430-A0002 but toyotapartsdeal.com was convinced it wasn't. Maybe I confused a link for D&F on my Hybrid, that's entirely possible at this point (another job I need to do). The more I think of it... that's what I did, wrote that down as being for both. My bad... Anyhow, when I take p/n's from toyotapartsdeal.com and try to check on ebay (shopping for best price), it seems to only confuse me more than not. The fill plug, I don't mind reusing the crush, the drain though I'd like to replace. I'd hit the dealer but I know they are going to do their utmost to convince me not to touch this (not sure why, but last time I was in there, that was what they did).

FWIW, I'm buying Aisin FE to fill for this, Rockauto seems best price here.

1.2L would be to refill after removing only the drain plug, and not the level straw (overflow tube).

I see what my problem is: they have a fill plug, and the other is ... not drain. It's overflow. Which is what you drain from... But that is part of the refill procedure, fill until it overflows (while running and at proper temp). The naming was throwing me off.

Overflow / drain: took me too long to see that it's the hex head on that plug that all videos show one draining the transmission from.

Note, I found a reddit thread that says the 90430-18008 is the Japan p/n, and the 90430-A0003 is the North America p/n. I guess that's a sourcing thing.

For CVT made in Japan that would be the part that was put on. For NA made one, it would be NA p/n. They have identical specs. For service in NA, service would likely order NA part from NA service part depot than pay for postage ordering the Japan part, which is the same part anyway...

Yes and no... Letting it drain overnight is unlikely to get that much more oil. Let it drain for 5 or 10 minutes, call it good enough. Measure and add the same amount back. If the car is reasonably level, it should be 2L (weird how the Aisin fluid comes in quart containers? I had to open a third so as to get to a full 2L, which is what came out).

But yes, you could do this, overnight, it's the same concept, just I'm not sure what it really gains to get 4 more drops.
