“While I was driving I had to stop on a hill and when I pushed the gas to accelerate it wouldn’t move the engine just revved up and hasn’t moved since just when you push on the gas and the rpm’s go up to 5-6 and it will move maybe a foot or so. There was no warning or messages that appeared before this happened and even now after it’s happens and it’s not showing any code to what’s wrong with it. It affected my safety and others because it wouldn’t move while in the middle of the road and I could have got in to a serious car accident because of it.”

“IN MY 006 IMPALA SS THE TRANSMISSION IS STARTING TO SLIP. THE CAR IS AROUND 83,000 MILES WHEN I FIRST NOTICED THIS ISSUE, AND THE VEHICLE WASN'T DOING ANY HARD ACCELERATION (AROUND 20-25 MILES AN HOUR SHIFTING FROM FIRST TO SECOND GEAR). I AM WORRIED THAT I WILL HAVE TO PAY TO GET IT REPLACED.”
