I'm the original owner. The car has had the emissions fix. In the morning, when the car is between 30 and 40 mph it shakes violently. If I accelerate through the shake it smooths out. After running for about 10 minutes the problem goes away. I've taken the car to a mechanic and they could need figure out what the cause is for this problem. The mechanic the computer was not showing any codes. I had the dealer shop look at a few years ago and the mechanic couldn't figure it out either, but said the transmission probably needs replacing. I wasn't going to spend a ton of money on a hunch. The car runs great all day except for the morning. When I return home from work it doesn't shake. Has anyone had this problem. If you have, what was the problem? I would appreciate any help. I'm afraid if I don't fix it it's going to damage the car, and I love this car!
