x Power Flow Path x Middle carrier locked, middle sun gear rotates x Rotation of the middle planetary gear sun gear while the carrier is fixed in place, decelerates and rotates the ring gear in reverse (front carrier), which transmits power to the front carrier. x The rear and front ring gears of the rear planetary gear rotate at reduced speed, causing the front sun gear of the front planetary gear to rotate in reverse under no load.

x Power Flow Path x Front sun gear, middle and rear carriers locked, and rear sun gear rotates continuously x When the rear sun gear rotates, power is reduced at the rear planetary gear and then delivered to the rear and front ring gears. Power is reduced again at the front planetary gear, whose sun gear is fixed in place, and then delivered to the front carrier. x Here the middle ring gear, integral with the front carrier, rotates and drives in reverse, zero-load rotation of the middle sun gear.

x Power Flow Path x Front sun gear and middle sun gear locked, and rear sun gear rotates continuously x Rotation of the rear sun gear transmits power to the rear and front ring gears, and the reaction of the front carrier and middle ring gear, to which the sun gear is attached, passes to the middle and rear carriers, resulting in power balance and power transmission to the front carrier.

x Power Flow Path x Front sun gear locked, middle and rear sun gears rotate x Rotation of the middle sun gear and rear sun gear transmits power to the rear and front ring gears, and the reaction from the front carrier and middle ring gear, to which the sun gear is attached, passes to the middle and rear carriers, resulting in power balance and power transmission to the front carrier.

x Power Flow Path x Front sun gear is locked, and rear carrier and rear sun gear rotate. x Activation of Overdrive Clutch (OD/C) synchronizes the rear planetary carrier and sun gears. 1:1 rotation passes through the rear and front ring gears and reaches the front planetary carrier, to which the front sun gear is attached. x Here, the mid sun gear of the mid planetary gear rotates at a higher speed in the normal direction and at zero load due to the reduced ring gear and carrier at 1:1 gear ratio.

x Power Flow Path x Mid and rear carriers, mid sun gear and rear sun gear rotate. x The mid carrier and mid planetary sun gear rotate simultaneously, resulting in a 1:1 rotation ratio transmitted to the mid ring gear (front carrier). x Here, the rear planetary gear rotates at a 1:1 gear ratio, as in 4th gear engagement; however, the front planetary gear remains unlocked, and the front sun gear rotates in the normal direction, at zero load and 1:1 gear ratio.

x Power Flow Path x Mid carrier rotates, mid sun gear is locked. x When the mid planetary sun gear is locked in place and the mid carrier is allowed to rotate, the mid ring gear increases rotational speed and transmits power to the front carrier. x Here, the rear planetary gear maintains a 1:1 gear ratio, as in 4th or 5th gear engagement; however, the front planetary gear remains unlocked, and the front sun gear rotates at a faster speed in the normal direction and at zero load.
