I really do not know a lot about cars and have been having an issue with vibrations when my car hits about 55. It does not vibrate all the time and will even start vibrating then stop at the same speed. I can hear and fell the vibration through the whole front of the car. I took it to one mechanic that said it was the engine protector and said there was nothing that could be done about it. I took it some where else and they said that it was a piece of my headlight that is broken on the inside of the head light(i know it is not that). I took it to yet a third place and they said it is my transmission bearings and my whole transmission needs to be replaced because the bearings inside of my transmission are bad. It is a 2009 with 70000 miles on it. I just find it hard to believe I need an entire new transmission. Any suggestions?
