I believe without taking it apart there is no way to know for sure. Someone else should confirm that though.

The only ways to know for sure are to drive it, or to crack open the case and start counting gear teeth.

Turn the input shaft and count the number of turns at the output. Do this for a couple of gears to determine the ratios.

YES !

This is correct . Do some math, and figure it out using this method.
