This is less an incident and more like a concern. I noticed a slight shudder upon accelerating. It started at lower speeds, approximately 25-30 mph, and shifting between second and third gear. Now with daily driving, the shudder has progressively gotten worse.
When Driving the vehicle, usually around 1500 rpm, you feel the transmission start to stutter, and during this stuttering, the whole car shakes violently. this violent shaking occurs on the highway with speeds of 70mph and over.
