Hoping someone can explain this issue. My 08' g37s coupe AT has been wanting to rev on it's own when I'm stopped. It's pretty scary! I'll be at a stoplight and the throttle will start to rev and jerk the car. I have to hold down the break real hard or put it into park to keep it from speeding forward! Also, I've noticed that when the car automatically downshifts, it's very rough and it seems to jerk forward quite a bit. Could this be a transmission issue? If so, what exactly is wrong and is it covered under warranty?
