However, it installs share/applications/transmission-gtk.desktop into the profile, containing
Exec=transmission-gtk %U i.e. it won't find it. transmission-cli works. I checked gnu/packages/bittorrent.scm , it seems to do some weird special-case for the gui (it puts the gui into a "gui" output and the rest into an "out" output). But $ guix package -i transmission:gui works. If that's supposed to be the official way, that's not discoverable. Also, the desktop file should also be in there, then it's at more consistent.
