engine vibrates on startup in park. Noise is coming from driver side of engine. At highway speeds it runs smoothly. Reoccurs intermittently at lower speeds. I jacked up car, got underneath, and pushed up on transmission (on the fluid pan) when noise was happening at this stopped the noise. I can push up the transmission about a 1/4 inch. When I do this, there is a thud sound when I let it down...I also here this thud when I hit a bump when driving. The car has been tuned up and motor mounts have been changed. I also took car to a frame shop and there is no frame damage. Hopefully this is an easy fix, any ideas are appreciated.
