Trans Modulator Compatibilty

I think my modulator on my tranny is broken. It shifts hard into 2nd and 3rd, and smooth into 4th. My vacuum lines seem to be fine and the line to the modulator holds a vacuum. I have a modulator from an 83 380SE (red, trans number 722.310). My car has a black one and it's an 84 300SD and the trans number should be 722.416 I believe?
Can I swap them to try it out, or do I need that specific one?
