22 Sienna e-CVT factory fill 50k uoa

[zyxelenator]

Hello folks. This is a factory fill from 2022 Sienna e-cvt transmission. Supposedly a life time fill with no recommended change interval. Some guys recommend changing it around 60k, including Car care nut guy that knows a thing or two about Toyotas. Decided to do a bit earlier at 50k, just for even numbers, next one would be at 100k. Like the van so far, and it seems we are racking up miles on it rather fast, especially considering that it does not have a duty of transportation to work (yet, but starting in near future). So for now I intend to keep it for a while.
Van does short trips often, to and from daycare that is just 4 miles away from home, playgrounds near by, but so it does longer trips on weekends and sometimes on workdays. Not sure if that has much negative effect on this fluid, this would be more of concern for engine oil. Fluid came out looking bright red and pretty much new.
Fluid was replaced with Idemitsu version of Toyota WS fluid(which Is one of the OE suppliers for Toyota in asian markets)
Anyway, here are the numbers:

Looks good compared to their averages. Nickel might come down & Silicon seems to be luck of the draw on some of these Trans UOA. Low viscosity but that's probably intended for mpg. Thanks

I think it is very clean for a ECVT. This is a regular 6 speed transmission.

UOA

I’m planning on a 30k tranny fluid change on my ‘23 Sienna.

I won’t be doing a UOA.

Good to know. I've been putting off our Camry, on the basis of, what's to wear? no clutches, no torque convertor to make heat. Been in no rush to do this, unlike other vehicles. I'm very leery of "lifetime" fluids in other applications--but this one, it might well be.

Take the word “lifetime” with a grain of salt.
