I was driving yesterday and my crossfire wouldn't shift out of 1st gear(automatic). I stopped at a traffic light, cut the car off to see if it would reset... To my surprise, it wouldn't crank again. Clicked as if the battery was dead. All lights, radio and A/C working fine. I used another battery to see if that was the problem, it's still doing the same. After getting it towed home, I put my battery in my other car, it fired right up. Can anyone give me direction on a fix or starting point?
