Tranny model
<!-- / icon and title --> <!-- message --> 87, F150 5.0 4x4. Its an auto.
The trans indicator reads P R N OD 2 1
Is this considered a 3 speed, or a 4 speed because of the overdrive?

As to 3 or 4: If the speeds are integrated into the trans, and controlled via one shifter (even with the silly buttons), it's a 4 or 5 or x speed trans.
Manual or auto does not matter.
If it has an OD unit on the tail, controlled by it's own switch or other mechanism, it's 3+ OD, or like Corvettes, Volvos etc, 4+ OD. (Even though the Volvo button was on the stick, the OD was on the tail separate from the trans. Not sure about the 'Vette.)
