The planetary gear trains are in the following conditions:
- Front planetary gear train
- Input: Ring gear
- Locked: Sun gear
- Output: Carrier
- Rear planetary gear train
- Input: Rear sun gear
- Locked: Carrier
- Output: Ring gear
Front Planetary Gear Train
The input shaft rotates in a clockwise direction, driven by the torque converter. The planetary ring gear rotates in a clockwise direction along with the planetary pinion gear which also rotates clockwise on its axis and orbit. The planetary sun gear is locked by the fluid pump which causes it to press against the planetary ring gear and orbit the sun gear, rotating on its axis.
The front planetary carrier rotates clockwise in the same direction as the planetary pinion gear. The clutch (C1) is activated and locks the planetary carrier to the rear planetary sun gear.
Rear Planetary Gear Train
The planetary sun gear rotates in a clockwise direction. The planetary short pinion gear rotates in a counter-clockwise direction. The planetary carrier attempts to rotate in the same direction but is restrained by the one-way clutch (F1).
The long pinion gear rotates clockwise on its axis and the middle sun gear rotates counter-clockwise while idling. The ring gear is rotated by the long pinion gear and drives the counter drive gear in a clockwise direction.
The counter driven gear is driven in a counter-clockwise direction which in turn drives the differential ring gear in a clockwise direction.
