According to my sources, putting the transmission in "S" engages
the band holding 2nd gear and elevates the hydraulic pressure.
Normally in "Drive" when shifting to second, there is a sprague
that engages in the forward direction(no engine braking).

When shifting to 3rd the sprague overruns and the direct clutch
holds the input and output shaft together.

The "L" works the same way only for first gear.
Here's a link to a diagram of the TH400 which is similar:
