My car has an automatic transmission.

Hi there. It is possible that you have a vacuum leak or perhaps the transmission mounts are loose, as usually these symptoms are common with worn out motor mounts. When the AC is activated, it does create additional drag on the motor, which can make a small vibration even worse. It’s probably a good idea to have a professional mechanic come to your location and try and replicate the symptoms you are describing by completing a car is shaking or vibrating inspection.
