How does a transformer work?
well.. thats not really the question..
I know it works with AC
but is it possible that it would work with DC?
ie. Im using a generator that outputs 60v. and i want it to be 13.5 v
im assuming the generator motor would have some ripple to it.
would the ripple be enough to induce to the secondary coil to make 13.5 v?

No, what you need is a DC to DC converter. The electronics in a DC to DC converter chops the input DC so a step down transformer can lower the voltage to 13.5. The output of the transformer would be rectified and filtered.

    A transformer will NOT work with direct current: period. The ripple will be so small as not to be effective for your requirement. Besides, the transformer will saturate and become very hot.

    It won’t work with d.c. because an alternating current in the primary winding sets up a changing magnetic field in its core, and that changing magnetic field produces lines of magnetic flux that cut the turns of the secondary winding. It is the change of that flux that induces a voltage in the secondary. If the primary is fed with direct current, once that current has stabilized (determined only by the resistance of the primary winding), the flux in the core is constant: not changing. So no induced voltage in the secondary.

    The best way to obtain 13.5 v d.c. from a source of 60 v.d.c. is to use a transistorised linear regulator circuit.That will also eliminate the ripple from the generator. Plenty of designs for this on the Web.
