Power braking/brake boosting/brake standing is all the same thing and it's never a good thing to do to an automatic transmission. It's also the absolute best way to kill a CVT by galling the belt and/or pulleysWell, I've watched a lot of YouTube videos about this, and read a lot about this for automatic transmission cars, but is this technique safe to do on our Sports? I mean i know everything is safe within moderation, but is it detrimental or harmful to the engine/transmission? Thank you for any advice.. This sounds like abnormal abuse to the engine/transmission to me, that's why I'm asking.
