Well, if memory serves me correctly, they don't have a transmission
per se. The prime mover drives a generator, and there are electric
motors on each powered axle.

The trick is that in "first gear" the motors are in series, with a
dropping resistor; in "second gear", in series with no resistor; in
"third gear", the motors are in parallel, with the resistor; in
"fourth gear", parallel with no resistor.
