Vibrations when Decelerating

I have a 94 YJ with a 3.5in Black Diamond lift and 32in AT tires however the back has sagged a bit. A few weeks ago out of nowhere I started getting vibrations that I could feel in the seat whenever I decelerated...this usually occurs at 40mph and above but it can be felt at any mph sometimes. Also, in the last part of a stop when the trans is not in gear I can sometimes see a noticeable side to side wobble in the trans and t-case shifter that is not simply from the engine running. Any ideas? Thanks

That is a broken transmission mount.

So the broken trans mount could be the cause of both of the problems I am having?

It could also be motor mounts (in addition), but I would bet on the transmission mount.
