I have booked an appointment tomorrow at the maintenance agent in my location, he will change the CVT transmission oil in addition to the filter, he told me that it is better to change the filter with the oil because this would extend the life of the transmission in addition to that when changing the filter, a larger amount of transmission fluid will come out, allowing the replacement of More quantity of it as a results. But my question now is how can they change the transmission fluid while it is hot, and I don't think they will wait until the transmission cools down completely, does that hurt the transmission or not, frankly, the issue is really confusing
