pressure control valve, solenoid valve, etc.

JSDIA1826GB
Part name Function
Torque converter It is composed of the cover converter, turbine assembly, stator, pump impeller assem-
bly, etc. It increases the engine torque and transmits the power to the transaxle.
Oil pump Through the oil pump drive chain, it uses the vane oil pump driven by the engine. It gen-
erates necessary oil pressure to circulate fluid and to operate the clutch and brake.
Counter gear set The power from the torque converter is transmitted to the primary pulley through the
counter drive gear and the counter driven gear.
Belt & pulley (Continuously variable transmis-
sion) It is composed of the primary pulley, secondary pulley, steel belt, etc. and the mecha-
nism performs shifting, changes the gear ratio and transmits the power with oil pressure
from the control valve.
Auxiliary gearbox (stepped transmission) It is composed of the planetary gear, multi-disc clutch, multi-disc brake, etc. and the
mechanism performs shifting (1-2 gear shifting and reverse) with oil pressure from the
control valve.
Reduction gear set Conveys power from the transmission mechanism to the reduction gear and the final
gear.
Parking mechanism When the shift lever is changed to P position, the mechanism fixes the parking gear (in-
tegrated with the reduction gear) and the fixes the output shaft.
Control valve Controls oil pressure from the oil pump to the pressure suitable for the line pressure
control system, shift control system, lock-up control system and lubrication system.
Pressure regu lator valve Adjusts the discharge pressure from the oil pump to the optimum pressure (line pres-
sure) corresponding to the driving condition.
Torque converter regulator valve Adjusts the feed pressure to the torque converter to the optimum pressure correspond-
ing to the driving condition.
Pilot valve Adjusts line pressure and produces a constant pressure (pilot pressure) necessary for
activating each solenoid valve.

FLUID COOLER & FL
UID WARMER SYSTEM
FLUID COOLER & FLUID WARMER SYSTEM : System DescriptionINFOID:0000000012431015
CVT FLUID COOLER SCHEMATIC
COMPONENT DESCRIPTION
CVT Oil Warmer
• The CVT oil warmer (1) is installed on the front part of transaxle
assembly.
• When engine is started while engine and CVT are cold, engine coolant temperature rises more quickly than CVT fluid tempera-
ture. CVT oil warmer is provided with two circuits for CVT and
engine coolant respectively so that warmed engine coolant warms
CVT quickly. This helps shorten CVT warming up time, improving
fuel economy.
• A cooling effect is obtained when CVT fluid temperature is high.
CVT Fluid Cooler (Water-cooling)
• The CVT fluid cooler (water-cooling) is installed in the radiator side tank (right side).
• CVT fluid is cooled by engine coolant.
SHIFT LOCK SYSTEM
Manual valve Distributes the clutch and brake operation pressures (pilot pressure) corresponding to
each shift position.
High clutch/reverse brake switching valve Switches the circuit for the high clutch and the reverse brake.
Torque converter clutch control valve It is operated with the torque converter clutch solenoid valve and it adjusts the tighten-
ing pressure and non-tightening pressure of the torque converter clutch piston of the
torque converter.
Primary pressure control valve It is operated with the primary pressure solenoid valve and adjusts the feed pressure to
the primary pulley.

INPUT/OUTPUT SIGNAL TABLE
SYSTEM DESCRIPTION
• CVT detects the vehicle driving status from switc hes, sensors and signals, and controls the vehicle so that
the optimum shift position and shift timing may always be achieved. It also controls the vehicle to reduce
shift and lockup shock, etc.
• Receives input signals from switches and sensors.
• Sends the output signal necessary for operation of solenoid valves, and evaluates the line pressure, shift timing, lockup operation, engine brake performance, etc.
• If a malfunction occurs on the electric system, activate the fail-safe mode only to drive the vehicle.

CVT CONTROL SYSTEM : Fail-safeINFOID:0000000012431019
TCM has a fail-safe mode. The mode functions so that operation can be continued even if the signal circuit of
the main electronically contro lled input/output parts is damaged.
If the vehicle shows following behaviors including “poor acceleration”, a malfunction of the applicable system
is detected by TCM and the vehicle may be in a fail-sa fe mode. At this time, check the DTC code and perform
inspection and repair according to the malfunction diagnosis procedures.

LOCK-UP CONTROL : System Description
INFOID:0000000012431024
SYSTEM DIAGRAM
DESCRIPTION
• Controls for improvement of the transmission effi ciency by engaging the torque converter clutch in the
torque converter and eliminating slip of the converter. Achieves comfortable driving with slip control of the
torque converter clutch.
• The oil pressure feed circuit for the torque converter clutch piston chamber is connected to the torque con- verter clutch control valve. The torque converter clut ch control valve is switched by the torque converter
clutch solenoid valve with the signal from TCM. This controls the oil pressure circuit, which is supplied to the
torque converter clutch piston chamber, to the release side or engagement side.
• If the CVT fluid temperature is low or the vehicle is in fail-safe mode due to malfunction, lock-up control is
prohibited.
Lock-up engagement
In lock-up engagement, the torque converter clutch solenoi d valve makes the torque converter clutch control
valve locked up to generate the lock-up apply pressure. This pushes the torque converter clutch piston for
engagement.
Lock-up release condition
In lock-up release, the torque converter clutch solenoid valve makes the torque converter clutch control valve
non-locked up to drain the lock-up apply pressure. This does not engage the torque converter clutch piston.
