On a '20 GT 10A with 30k miles: in S mode there is sometimes a loud bang if I blip the throttle. It's happened at 30mph and 80. Its violent and shakes the car, almost thought I had broken a driveshaft. I know shifts are supposed to be hard to be fast but this seems excessive. Otherwise it shifts normally in D and S. I autocross but it's never happened racing. The car is under a certified used engine/drivetrain warranty but want to see if this is normal or not.
