Rattle/Scratching noise from the Transmission(Updated with video)

Ok fellas, I upgraded some transmission hardware the other day. Dinnan short shifter, cdv delete, and uuc blue street/track transmission mounts. As expected I have more transmission noise in the cabin. However, I've noticed a
Scratching sound. Like bolts in a can when driving at low speeds in any gear. No noise when still. It doesn't do it every time and is amplified when I shift. But then goes away. I understand these transmissions can exhibit gear chatter when using a single mass flywheel, but mine is stock. I've done some research and I believe this noise was there before, but the sound was being absorbed by the stock soft mounts. I'm looking for alternative opinions. I'm gonna have my service tech Flo take a look and listen. Give me your input.
