What are the signs of a bad transmission mount on a Mustang?

[v8ismyheart]

I’ve been noticing some weird vibrations when I accelerate or shift in my Mustang, and I’m starting to wonder if it could be a bad transmission mount. Could that be causing the issue? I’ve also been hearing some occasional clunking noises. Is this something I should be worried about, and how can I check if the transmission mount is the problem? Would love to hear if anyone else has dealt with this and what the signs were.
