Transmission Control Systems: Description and Operation

POWERTRAIN
- Power from the transmission is transmitted from the ring gear to the center differential. Also, because the pinion shaft is connected to the inside of the center differential, the power is transmitted from the pinion shaft to the pinion gear and then to the side gear on both sides.
- Power transmitted to the left side gear of the center differential is then transmitted to the front differential case and further transmitted from the pinion shaft pinion gear both side gears. The drive shaft is interlocked with the side gear so power is transmitted from the drive shaft to the front wheels.
- Power transmitted to the right side gear of the center differential is transmitted from the transfer drive gear to the transfer driven gear, changes direction and is then transmitted from the propeller shaft to the rear differential.
- On the other hand, when hydraulic pressure acts on the center differential control clutch, power is also transmitted from the ring gear mounting case to the front differential case.
