Hi I'm driving a 2007 Nissan Latio CVT. Last week, when there was a jam at the entrance of a carpark, just nice I stopped at the slope. When I was about to move, my car deem to be rolling backward. I quickly change my gear to L. But same thing happen, car rolling backward. I had to step on the accelerator to rpm 5k and above then my car manage to move forward. Anyone facing the same problem? Or is there something wrong with my gearbox? Thks.
