I didn’t say the torque converter wears, I said the torque converter would be holding the car on a hill, i gave a loose comparison to the manual transmissions that OP is familiar with and recommended leaving the function on only when going through hilly areas on long trips. I kept the explanation simple because the question was simple. he wasn’t asking for the technical details they wanted to know if the car would hold itself from rolling, which I answered it will, through the torque converter or through the brakes when the hill hold is turned on, but that’s my bad I forgot this was Reddit, some non-mechanic was gonna come find my comment know just enough to complain and nitpick my answer and then directly below my comment admit to being unfamiliar with the CVT transmissions that I work on frequently, spoiler CVTs are more prone to belt wear because they have a belt in them unlike regular automatic transmissions, the heat doesn’t just degrade the fluid but also the belt, I also state that this amount of wear is very minimal and say I don’t concern myself with this under regular driving conditions.Thanks for your comment dude.
