transmission part

I got my 2006 galant about 2 years ago now. lately its been kinda clunky with the tranny, so I
got the car picked up on a hoist and did a little looking around, only to find the transmission
mount is completely broke.. I'd buy a new one..if I could.. only problem is whenever I look up
"transmission mount" I got the part the trans mounts onto.. I need the part thats attached to
the trans, that attaches to the mount..
its almost as if it looks like the part itself is part of the trans, but upon close inspection, its
clear to me that its a seperate part...

any idea what this part is actually called? and where I can find out outside of a dealership?
napa doesn't sell it either.
