Kia Carnival (2007 year). Manual — part 90

3rd GEAR POWER FLOW

Hydraulic pressure is applied to the UD clutch(A) and the OD clutch(B), then the UD clutch transmits driving force from
the input shaft to the UD sun gear, and the OD clutch transmits driving force from the input shaft to the overdrive
planetary carrier and low&reverse annulus gear.The UD sun gear of the planetary gear drives the output pinion gear
and the LR annulus gear, and the LR annulus gear drives the OD pinion gear through the OD planetary carrier, and
the OD pinion gear drives the reverse sun gear and the output carrier.The OD clutch drives the OD carrier, and the
OD carrier drives the OD pinion gear, and the OD pinion gear drives the reverse sun gear and the output carrier, and
the output carrier drives the transfer drive gear, and the transfer drive gear drives the transfer driven gear of the
output shaft, and power is transmitted to the differential gear through the differential drive gear.

4th GEAR POWER FLOW

Hydraulic pressure is applied to the OD clutch(A) and the 2nd brake(B), then the OD clutch transmits driving force
from the input shaft to the OD planetary carrier and LR annulus gear, and the 2nd brake locks the reverse sun gear to
the case.The OD clutch drives the OD carrier, and the OD carrier drives the OD pinion gear and the LR annulus gear,
and the OD pinion gear drives the output carrier, and the output carrier drives the transfer drive gear, and the transfer
drive gear drives the transfer driven gear of the output shaft, and power is transmitted to the differential gear through
the differential drive gear.

Reverse GEAR POWER FLOW

Hydraulic pressure is applied to the reverse clutch(A) and the LR brake(B), then the reverse clutch transmits driving
force from the input shaft to the reverse sun gear, and the LR brake locks the LR annulus gear and OD planetary
carrier to the case.The reverse clutch drives the reverse sun gear, and the reverse sun gear drives the output carrier
through the OD pinion gear, and the output carrier drives the transfer drive gear, and the transfer drive gear drives the
transfer driven gear of the output shaft, and power is transmitted to the differential gear through the differential drive
gear.

DIAGNOSIS FLOW

INSPECTION CHART FOR TROUBLE SYMPTOMS

Trouble symptom

Probable cause

Communication with HI-SCAN is not possible
If communication with the HI-SCAN is not possible, the cause is
probably a defective diagnosis line or the TCM(PCM) is not
functioning.

a. Malfunction diagnosis line

b. Malfunction of connector

c. Malfunction of the TCM(PCM)

functioning.

c. Malfunction of the TCM(PCM)

Driving impossible

Starting impossible
Starting is not possible when the selector
lever is in P or N range. In such cases, the
cause is probably a defective engine system,
torque converter or oil pump.

a. Malfunction of the engine system

b. Malfunction of the torque converter

c. Malfunction of the oil pump

Does not move forward
If the vehicle does not move forward when
the selector lever is shifted from N to D, 3, 2
or L range while the engine is idling, the
cause is probably abnormal line pressure or a
malfunction of the underdrive clutch or valve
body.

a. Abnormal line pressure

b. Malfunction of the underdrive solenoid

valve

c. Malfunction of the underdrive clutch

d. Malfunction of the valve body

Does not reverse
If the vehicle does not reverse when the
selector lever is shifted from N to R range
while the engine is idling, the cause is
probably abnormal pressure in the reverse
clutch or low and reverse brake or a
malfunction of the reverse clutch, low and
reverse brake or valve body.

a. Abnormal reverse clutch pressure

b. Abnormal low and reverse brake pressure

c. Malfunction of the low and reverse brake

solenoid valve

d. Malfunction of the reverse clutch

e. Malfunction of the low and reverse brake

f. Malfunction of the valve body

Does not move (forward or reverse)
If the vehicle does not move forward or
reverse when the selector lever is shifted to
any position while the engine is idling, the
cause is probably abnormal line pressure or a
malfunction of the power train, oil pump or
valve body.

a. Abnormal line pressure

b. Malfunction of power train

c. Malfunction of the oil pump

d. Malfunction of the valve body

Malfunction when
starting

Engine stalling when shifting
If the engine stalls when the selector lever is
shifted from N to D or R range while the
engine is idling, the cause is probably a
malfunction of the engine system, damper
clutch solenoid valve, valve body or torque
converter (damper clutch malfunction).

a. Malfunction of the engine system

b. Malfunction of the damper clutch control

solenoid valve

c. Malfunction of the valve body

d. Malfunction of the torque converter

(Malfunction of the damper clutch)

Shocks when changing from N to D and large
time lag
If abnormal shocks or a time lag of 2 seconds
or more occur when the selector lever is
shifted from N to D range while the engine is
idling, the cause is probably abnormal
underdrive clutch pressure or a malfunction of
the underdrive clutch, valve body or idle
position switch.

a. Abnormal underdrive clutch pressure

b. Abnormal low and reverse brake pressure

c. Malfunction of the underdrive solenoid

valve

d. Malfunction of the valve body

e. Malfunction of the idle position switch

Malfunction when
starting

Shocks when changing from N to R and large
time lag
If abnormal shocks or a time lag of 2 seconds
or more occur when the selector lever is
shifted from N to R range while the engine is
idling, the cause is probably abnormal reverse
clutch pressure or low and reverse brake
pressure, or a malfunction of the reverse
clutch, low and reverse brake, valve body or
idle position switch.

a. Abnormal reverse clutch pressure

b. Abnormal low and reverse brake pressure

c. Malfunction of the low and reverse

solenoid valve

d. Malfunction of the reverse clutch

e. Malfunction of the low and reverse brake

f. Malfunction of the valve body

g. Malfunction of the idle position switch
