I am a first time Viper owner, 2005. When the car idles, the shifter vibrates. When driving, and I accelerate, the shifter torques....especially with a rapid and sudden acceleration. With a very rapid acceleration that causes the tires to spin, the shifter torques violently. Is this normal, or does it indicate a broken motor mount, or some other issue? Not sure if this matters, but the car does have a short shifter. Thank you for helping!
