Manual transmission rattle

[Dickinson County Comanche]

Hey all, I have this rattle in my transmission and it’s irritating me. I don’t understand for the life of me what it is. It started about 2 weeks after I swapped power trains in my truck. It rattles upon the clutch being released and rattles while the engine is idling. I can make the rattle go away by simply pushing on the transmission. I put brand new mounts and it is tight so that is not the issue. The video makes it much more pronounced than it actually is, but it’s like a full-on rattle. Bellhousing bolts are tight, the mounts are tight. I’m at a loss

Pilot bearing/bushing going bad?

Maybe, I’m still just a bit confused about the rattle going away when I push on the transmission/transfer case. Maybe a bad input bearing on the transfer case too?
