The DC resistance of the transformer windings are added to the source impedance (and transformed by a step-down ratio, if that is used) to get the output impedance of the combination, so your results make sense. If you want lower output impedance, then you must use a transformer with lower resistance windings. The LL1545A was not designed to be an output transformer. Something like the LL1527 would be a better choice.
