is there something to do with the engine mountings?
My car has 30000 miles.
My car has an automatic transmission.
Hello - yes, it is possible the motor mounts are bad if the engine vibration is more noticeable when in Drive or Reverse. Worn or broken motor mounts allow the engine to twist when applying power. This can cause the engine to touch a metal part of the chassis, transmitting vibration and noise into the passenger compartment. I would recommend an inspection of the engine/transmission mounts](https://www.yourmechanic.com/services/car-is-shaking-or-vibrating-inspection) by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, give you an accurate assessment of damage and cost estimate for repairs.
