How does the 2 speed Opti Drive work for shifting?

Well, Traxxas could used the signal from the sensor to tigger the controller to momentarily interupt the throttle signal to the esc, thus killing the power for a second while the tranny shifts. Kind of like how traction control or manumatic trannys work in full size cars. Not sure if that would cause issues with the esc or motors, but would allow the tranny to shift without full power thru it.
