6. CAN NETWORK
The TCU sends signals to be used by other vehicle systems via the CAN bus, such as:
Selector lever position
Selected gear state
Manual mode activation
Output torque
Transaxle fluid temperature

assembly
inal reduction and
differential gearThis is a fluid clutch.
Transfers the power from
engine to transaxle and
amplifies the torque.Transfers the power
from torque converter
to front planetary
gear.Generates the gear
ratio and transfers the
power.
Engaged by hydraulic
pressure and transfers the
power to C1 clutch.Transfers the power from
torque converter to rear
planetary gear.Generates the gear ratio
and transfers the power.
Engaged by hydraulic
pressure and transfers the
power to C1 clutch.Transfers the power from
input shaft to intermediate
shaft.Changes the rotating direction
and generates the final
reduction rear ratio.
Generates the final reduction gear ratio and performs
the differential function.
Transfers the power to constant velocity shaft.
