You need LimitCORE=infinity in your service file (which does the same as
ulimit -c unlimited in sysv init scripts).

With that setting, getting a core dump works fine on my machine,
i.e. after installing transmission-daemon 2.81-1 and dropping the
following file in
/etc/systemd/system/transmission-daemon.service.d/fixes.conf:

[Service]
LimitCORE=infinity
User=debian-transmission

I get a core dump after running systemctl daemon-reload && systemctl
restart transmission-daemon.service.

Can you confirm that it works for you? Then I’ll close the bug.
