need a quick answer, is it a 4 speed?

If you wind up buying the trans, one sure fire way to tell if it's an O/D or 1:1 A833 is by looking in the side cover and examining the gears. Especially the countershaft cluster gear.

On a regular 1:1, the gears on the countershaft progressively get smaller from the front to back. On an O/D, the 3rd gear, which is the 2nd to front gear, is replaced with a .73:1 gear. So this means the the gears from front to back go large, then largest, then progressively get smaller to the back.

This is why they flipped the arm down on the front of the side cover, because the gear actuation using the shifter in it's H pattern actually shifts the gears 1-2-4-3, since 3 is now O/D.

Hope this helps!
