if it does it in park then it may be the torque converter is the problem you can check a balancer by marking it at #1 then start the car give it a quick rev then bring it back to #1 if the mark has moved the balancer rubber may have broken. Or it could be the flywheel/flexplate is the wrong one.

also check for misfire or wrong firing order and engine/transmission mounts as well.
