Pushed the gas pedal to the floor to get through a light. The car didn't accelerate right away but then shuttered and shook like I hit a speed bump at a high speed (which I didn't). I thought I went over a huge pot hole. I even went back the next day to inspect the road where it happened & the road was flat. No holes. When it happened I thought my wheels were about to fall off or I jerked a part out of the transmission by simply pressing on the gas pedal.
