Most likely cause is a leaking trans cooler (part within radiator).
No static test for this....I'd exchange the radiator pronto before the leak gets worse and allows coolant under pressure (at engine shut off) to push into the trans...........Actually, I think a trans flush would be wise in conjunction.
