I had a small vibration in my 04 LJ at about 50 mph . Installed a new generic trans. mount and now I still have the same vibration plus vibration at idle .Does anyone have a clue what this is ? (Auto trans,4,0,stock 373 gears and 32'"BFGoodrich All Terrains with no lift) Thanks
Increased noise / vibration after installing new transmission mount

Yep, this is a very common issue. Someone else had this issue recently. Can't recall if it was @89grand, @Steel City 06, or someone else. However, my understanding is once they replaced the genetic mount with a Mopar factory mount, the vibration and noise went away.
I'm guessing the Chinese mount you (and others) installed is a much harder material, this the increased NVH.

If you installed a polyurethane mount that's why. Polyurethane transmits vibrations far more readily than the OE rubber mount does. Replace it with a Mopar rubber mount and those new vibes should go away. Caution that some aftermarket rubber mounts are so stiff they also transfer more vibrations.
Wasn't me unfortunately. I did shim my stock mount up using washers and later bar stock to prevent shifter contact. No vibrations from that though
BTDT too. I replaced a NAPA mount with a Crown, and the Jeep is back to normal and smooth like buttah. And the Crown won't set you back Mopar money. I have pics of the Crown and NAPA along side each other here:
