Check your transmission mount, the fact that the car does it in park helps trace where it is coming from, because the rear end is not turning or the driveshaft. Check the mount, and also check your torque converter bolts.

Could be exhaust touching somewhere or trans or motor mounts. Converter could be another. Also check oil level in car. If its overfilled it will vibrate too. Just some things to check.
