I have to respectfully disagree with RustyRatRod. I agree that forward gears should be counted, but only until you get to a 1:1 gear ratio which, in the case of the A833 OD tranny, is 3rd gear. '4th' gear is an overdrive ratio, thus, it truly is a 3-speed overdrive. Hate how tight 1st gear is to 2nd. It's like the Power Glide of manual transmissions.
