Yes and no Joe.
The shift lever selects first and reverse manually.
As to how the two ratios are achieved.
not like a manual box, not different cogs.
There are two planetary gear sets, that are always engaged. There are three elements toq each set, Sun gear, Planet gears and Ring gear.
The drive is applied to one of these elements, the output is taken form one of the others, and we use a clutch or brake to hold the third element still, to achieve the ratios.
