Hello all, So I am at 47,000 miles on our 2021 Platinum AWD. I want to change the fluid on both the transmission and the AWD system but wanted to confirm that it is Toyota Genuine ATF WS? Also, I thought it was a CVT, is that the same thing as "hybrid transmission"? I attached a screenshot of the manual. This might seem like a silly question but I want this thing to last Thanks!

ATF WS. The hybrid eCVT is nothing like a normal CVT.

What’s the deal with this new Genuine Toyota CVT FE Transmission Fluid?

Not for hybrid eCVT, it's for ICE vehicles with traditional CVT transmission.

For my 2023 model, it is an

Electronically controlled Continuously Variable Transmission (eCVT) with sequential shift mode

Edit: ATF WS as stated in the OM.

47,000 miles is a little early for the tranny fluid. Wait till at least 60k. I got it changed today at 85,000 miles

I have 140,000 miles on the Prius. I think I changed it once at around 90,000 miles. Same time I did the spark plugs and inverter/engine coolant. I think the Prius manual says to change it but the Sienna manual says to just check it. I would still change it though.

Toyota should have never called it a CVT. Same thing with TRD. Their acronym game sucks. Lol.
