Can anyone tell me how to change the CVT Fluid on a 2021 Corolla Hybrid?

It's an easy drain and refill for your P610 Power Split Device (Electronic CVT). Total capacity is 3.8 US quarts (3.6 liters) of Toyota's low-viscosity ATF WS... It does not require any fancy or specific fluid as its purpose is for lubricating and cooling only, of the planetary and differential gears and bearings, and both electric motors/generators. I've replaced the fluid twice in a Lexus CT200h with ACDelco Dexron-VI ATF instead.

It'll look a lot like this after you remove the big plastic splash panel underneath. Many plastic push pins to release and remove, and a few bolts in front... Many like using a pump on the quarts of fluid, but that's with the car jacked up level.

You just need to jack up front end, remove fill plug, then the drain plug. Let it drain thoroughly, then reinstall drain plug. Route a hose on funnel from above engine, into fill port. Drop front of car back down. Add ATF until it starts dripping out with car parked level. Jack up front of car, reinstall fill plug and splash guard.

I am impressed (y) I was thinking to have my Camry hybrid done by dealer and I was given a quote around $350 o_O I am thinking to do it myself but I am quite nervous. My most worry is that I won't be able to drain them all out and then there will be a mixture between new fluid and old one. The dealer they have the equipment to flush all the old one out before they refill it.
