High-Low Planetary Gear Set

Establishes an auxiliary transmission mechanism. When the TOD switch is set to the 2H or TOD position, the reduction gear ratio is 1.000 and the corresponding driving force is generated. When the TOD switch is set to the 4L position, the reduction gear ratio is 2.480 and the corresponding driving force is generated.
