Transformer may heat up for reasons that are not its own; it could be loaded heavier than appropriate.
But if it did not sustain damage, it could be OK.
To me a good way of testing it is plugging it in 120V and running it with no load. If it does not heat up (could get a tad warm) considerably, it is OK (no turn short).
Ohming out is the first check, of course, but it will not reveal a turn short.
This test will.
(BTW this is one instance where I approve using a dim bulb tester).

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
