Transmutation constitutes an even more fundamental change/manipulation of matter than what Magneto does. Magnetic properties of matter are mostly the result of its constituent atoms and molecules having unpaired valence electron spins [a]. This gives rise to atomic/molecular magnetic moments which can then interact with external magnetic fields (such as those of Magneto). Magneto still has to overcome the metallic bonds present in adamantium in order to break it.

In contrast, transmutation involves change in the atomic number of the constituent elements of matter ("nuclear reactions"😉. This requires fusions/fissions of nuclei, and/or changing protons into neutrons (or vice versa) possibly via electron/positron emission or capture ("beta decay"😉. Such manipulations would in general require mastery over not only the EM but also the strong and weak forces. Once the atomic nuclei in adamantium have been transformed into, say, helium nuclei the electrons would have no choice but to rearrange around these new nuclei, which would automatically break the metal apart. Thus, as long as adamantium is made of electrons and nuclei, a being capable of transmutation should trivially be able to break/change it. It shouldn't even be any harder than the transmutation of any other material, since the building blocks (electrons, protons, neutrons) are the same.

[a] Matter can also display nuclear paramagnetism (in addition to / instead of electronic paramagnetism) but this is thousands of times weaker than the electronic one, due to the magnetogyric ratio of the electron being thousands of times larger than that of a typical atomic nucleus (i.o.w. an electron is MUCH more "magnetic" than a nucleus). Nevertheless, the phenomenon of nuclear paramagnetism has some important applications, of which the magnetic resonance imaging (MRI) used in the hospitals is probably the most well-known one.

I'm not familiar with Firestorm, other than it's his thing.Matter/reality manipulation - or magic - can affect adamantium, as long as the user wields enough power and is competent with it.
Firestorm is a dc loser, so he would probably end up eating his own ass with Galan ejaculating on his face.
