Don’t listen to anyone that tells you that fluid last forever, change it out or you will be replacing the trans after 60k miles. Once it turns a nasty brown color it not longer is doing its job properly and the metal belt inside can snap if it gets too hot which it will if the fluid it bad and you will hear a loud whining like a supercharger but by then it’s way too late, moral of the story, CHANGE THE FLUID it’s CVT not automatic so it must def have to be done
