Ok thanks.I can understand it could be any one of these that could cause vibration however I don't understand why the car has to be hot before the vibration starts on highway or stop. Wouldn't any of the things you mentioned be happening all the time whether the car is hot or not. Oh well I will have to find a mechanic that can help figure out where this vibration is coming from. Car has already been to 3 mechanics and I have spent over $400 and I am still no further ahead. Next step according to the last mechanic was to take it to a tranny specialist
I called the mechanic that last looked at the car after I received your first reply and he said he checked the motor mounts.. All was fine
when I stop at the light the vibration is not heard all of the time. It is roughly 50-50. Seems to depend on outside temp. The colder it is outside the more vibration. But it happens only in drive or reverse. If I am stopped and the engine is vibrating if I hold the brake and just touch the gas pedal to increase rpm by maybe 200 while still in drive the vibration stops. Today it was 34 degrees here and no vibration at a stop. Lots on the highway but none at a stop.
The higway vibration is constant once the car is warmed up.
Last night when engine was warm I stopped and held the brake and reved the engine while in drive.I felt no vibration and heard no strange noises.
