AT Drain plug Thread pitch?

[SouthArk370Z]

If nobody here knows, I'd try calling a (few) Nissan parts department(s) and asking for p/n and specs. You might get lucky and the parts guy/gal can tell size/pitch by looking at one.

Edit: Or just about any auto parts store. Should be a common item.

Edit 2: Since the trans is supposed to be a no-user-servicable-parts-inside type of deal, the drain plug may not be something every parts store carries. Nissan probably uses the same plug in other transmissions if you can find a cross-reference.
