Looked in my manual for my '02 F150 4x4, see that there are (2) trannies listed, one takes Mercon fluid, one takes Mercon V fluid.

One is the 4W100 (I think), the other is the 4W23(?).

How do I tell which one I have?

Very few 99+ F-150's received the 4R100, except the 7 lug 7700 series, and the 2WD Lightning/Harley Davidson F-150's. The 4R100 transmission has a pan bolt count of 20, the 4R70W has fewer, I believe 14. Look at the sticker in the door jamb. The 4R70W is transmission code U, the 4R100 is transmission code E.
