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.

CONSULT DATA MONITOR STANDARD VALUE
• In CONSULT, electric shift timing or lock-up timing, i. e. operation timing of each solenoid valve, is displayed.
Therefore, if there is an obvious difference between t he shift timing estimated from a shift shock (or engine
speed variations) and that shown on the CONSULT, the mechanism parts (including the hydraulic circuit)
excluding the solenoids and sensors may be malfunctioning. In this case, check the mechanical parts follow-
ing the appropriate diagnosis procedure.
• Shift point (gear position) displayed on CONSULT slight ly differs from shift pattern described in Service Man-
ual. This is due to the following reasons.
- Actual shift pattern may vary slightly within specified tolerances.
- While shift pattern described in Service Manual indica tes start of each shift, CONSULT shows gear position
at end of shift.
- The solenoid display (ON/OFF) on CONSULT is changed at the start of gear shifting. In contrast, the gear
position display is changed at the time when gear shif ting calculated in the control unit is completed.
