I've documented in this thread that my aveo has been affected by this problem since I have owned the vehicle. Today my aveo succumbed to the issue and stopped working. My aveo stopped being able to shift into overdrive and the check engine light turned on and another HOLD light began flashing. At this point I assumed there had to be an issue with my transmission.

I took into a Chevrolet dealership and turned the keys in. I told them the problem and asked if they could replace the spark plugs and boots as well. They told me they couldn't replace the plugs and boots because they didn't have the kits in stock. After about an hour and a half they called me back and told me my car was ready. The problem turned out to be solely my spark plugs and conveniently they were able to find a kit to replace it.

My car is driving great now. I'm about to take an hour long drive on the interstate and i'm excited to test my fuel economy with the new plugs.
