I have a 2013 Nissan Maxima with a 3.5L V6 and a CVT transmission. Like most CVTs these days, it has a "manual mode" where the driver can manually change the gear ratios by shifting through simulated gears 1 to 6.
Yesterday I let a friend test drive my car, and of course, he switched over to manual mode without knowing how to use it. He floored it and held the engine around 6500 RPM while staying in first gear the entire time. He kept this up until the car reached 60-70 KPH. When he eventually let go of the accelerator (still in first gear and revving at 6500 RPM), the car jolted as if it was being engine braked... I did not like the feeling of that at all.
Is there going to be any damage to my engine/transmission as a result of this?
