    While I wait for my new cylinder batteries to come in from 2K 1 toaster, I thought it would be a good time to change the CVT fluid. Does the temperature matter when draining? If the car has been sitting for an entire day, wouldn't most of it be able to drain, or does it need to have been warmed and circulating? Thanks.

    It'll take slightly longer for oil to drain out. But other than that it doesn't really matter.
