This weekend I did some diagnosis on my Driverside Upper Trans mount and Passenger Side Motor Mount. All of the bolts are torqued to spec. I ran a couple of tests to check for engine movement, and noticed that the Driverside Upper Trans Mount seems to have excessive movement, which may be the source of my drivetrain clunk/movement that has been driving me crazy all this time!
Here are the details on the 2 tests I ran:
Test #1: With the Car in N, and the Ebrake on, I shook the engine by hand and looked at how much play the mounts allowed. The Passenger Side Engine mount looked good, and didn't seem to allow as much as the Driver Side Trans mount (which seemed pretty loose)
Here are 2 videos I took of this, focused on the Driver Side Trans Mount:

Does this look like too much play in the mount, or is it normal?
Test #2: I put the car in 1st gear, with no E Brake on. I rocked the car back and fourth. The video shows the Driver Side Trans Mount:

If you look closely, when the engine moves forward, it just doesn't tilt smoothly, but almost has a disjointed movement, which may be the cause of my issue. The Passenger Side Engine Mount seems to move normally and in a more restricted manner. What do you guys think?
I have already replaced the dogbone mount, and that hasn't made a difference. All of my other suspension pieces seem to be in order. Since the Passenger Side Engine mount doesn't seem to allow as much play, I am thinking the Driver Side Trans Mount is defective. The car has 7000 miles on it and has had this excessive drivetrain movement/clunk in it since new. I am at the point where I think I will just drop $150 for a new mount and bolts to see if it fix it.
Also, here are a couple of other videos I took for anyone interested:
