InspectionINFOID:0000000012430963
INSPECTION AFTER INSTALLATION
• Check the operation of the control linkage. Refer to TM-21, "Inspection".
• Before starting engine, check oil/fluid levels incl uding engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to MA-11, "
Fluids and Lubricants".
• Use procedure below to check for fuel leaks.
• Turn ignition switch ON (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leaks at connection points.
• Start engine. With engine speed increased, check again for fuel leaks at connection points.
• Run engine to check for unusual noise and vibration. NOTE:
If hydraulic pressure inside timing chain tensioner drops after removal and installation, slack in the guide
may generate a pounding noise during and just after engine start. However, this is normal. Noise will stop
after hydraulic pressure rises.
• Warm up engine thoroughly to make sure there is no lea ks of fuel, exhaust gas, or any oils/fluids including
engine oil and engine coolant.
• Bleed air from passages in lines and hoses, such as in cooling system.
• After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to spec-
ified level, if necessary.
• Summary of the inspection items:
*Power steering fluid, brake fluid, etc.

TRANSAXLE : Oil Pressure System INFOID:0000000012431013
Oil pressure required for operation of the transaxle transmission mechanism is generated by oil pump, oil
pressure control valve, solenoid valve, etc.
TRANSAXLE : Component DescriptionINFOID:0000000012431014
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.

LINE PRESSURE CONTROL : System Description
INFOID:0000000012431021
SYSTEM DIAGRAM
DESCRIPTION
Highly accurate line pressure control (secondary pressure control) reduces friction for improvement of fuel
economy.
Normal Oil Pressure Control
Appropriate line pressure and secondary pressure su itable for driving condition are determined based on the
accelerator pedal position, engine speed, primary pulle y (input) speed, secondary pulley (output) speed, vehi-
cle speed, input torque, stop lamp switch signal, transmission range switch signal, lock-up signal, power volt-
age, target shift ratio, oil temperature and oil pressure.
Secondary Pressure Feedback Control
In normal oil pressure control and oil pressure control in shifting, highly accurate secondary pressure is deter-
mined by detecting the secondary pressure using a oil pressure sensor and by feedback control.

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.

IDLE NEUTRAL CONTROL : System DescriptionINFOID:0000000012431025
SYSTEM DIAGRAM
DESCRIPTION
If a driver has no intention of starting the vehicle in D position, TCM operates the low brake solenoid valve and
controls the oil pressure of the low brake to be low pressure. Therefore, the low brake is in the release (slip)
status and the power transmission route of transaxle is the same status as the N position. In this way, the tran-
saxle is in idling status and load to the engine can be reduced to improve fuel economy.
