Good aftermarket brand for 2018 Subaru XV Lineartronic CVT Fluid

Because like most non-MT trannies only do drain & refill. The dialysis method is more complex and more expensive. You are practically changing all fluid in the tranny with the dialysis method. That’s about 13L.

Does that mean that we never need to do the dialysis method for the life of the car? Do you happen to know the reason why most people in the US do dialysis instead of drain and refill?

I have no idea. I guess It’s cheaper for them to do it that way. Some people in the US also do drain and refill.

from what i understand,
draining and refilling just replaces the free oil in the trans box.
the oil inside the torque converter does not drain that well, in plain drain and refill method.
this is where dialysis method comes in.
in dialysis method, the oil inside the torque converter becomes part of the circulating oil that is constantly being drained of dirty oil and refilled with clean oil.

Transmission fluid flushes miss 1 vital thing...FILTER REPLACEMENT! It's rather unwise to go to just any shop where you have no assurance nor idea of how their flush(dialysis) equipment has been maintained...or who knows, they might mix-use theirs for various CVTs & other types of ATs. There's that risk of having some amount of wrong fluid mixed with the recommended + that attached below... More harm than good.
Drain, replace the filter & fill multiple times is the safer way & is what most manufacturers recommend.

i saw some videos in youtube doing DIY transmission flush by tapping at the fluid cooler lines.. they let the transmission dump the old fluid and feed new fluid with help of gravity..

but last time i did an ATF change, i just perform the trusty drain and fill at 40k kms.. did it twice in interval of 2.5k kms.. on the 2nd flush, ATF is back is reddish color.

Or, DIY casa style, not flush/dialysis.[emoji4]

My take away from the article is not to do a flush but just a drain and refill. And since the casa for Subaru cars is using flush/dialysis method, then it's "avoid casa" for me.

That makes sense. If I think of it, it's the same concept as my computer water cooling system. The main point in the system is to never run the pump of the system dry and it is impossible to get 100% of the old liquid out when replacing it.

the ATF dialysis method will utilize the ATF cooler lines... i think, much better to do the gravity feed if you really want the dialysis method, let the transmission pump suck and dump the atf.. just make sure you have sufficient fresh atf for continuous feed.
