Every car will move an inch to two,unless you set parking brake.Maybe not an inch or two,but it will move
My garage is fairly level and none of my prior cars moved. The CT moves...no joke! Maybe it's because I ALWAYS shut my car down w/out putting it in park, as it's not necessary to have to push 2 buttons.
I'm aware of that,I wasn't able to find 3 rd gen transmission info . Both work similarWe are now on 3rd gen and the ECVT stands for electronic, which is involved with providing power to the stator winding which are similar to a solenoid or electromagnet --no voltage = no eletromagnetic field = no resistance. Also the clutch is electronic and is not engaged.
I can read and understand.but, what happens in real life dictates what I do. I used only the power button and the car rolled more then I've felt using both buttons . Maybe it was just a fluke, but hitting two buttons doesn't slow or bother me enough to care
