STRUCTURE AND OPERATION

TRANSAXLE : Component Description

INFOID:0000000012201095

FLUID COOLER & FLUID WARMER SYSTEM

Part name

Function

Torque converter

Increases engine torque and transmits it to the transaxle.

Oil pump

Utilizes a vane-type oil pump that is driven by the engine through the oil pump drive chain in order to
increase efficiency of pump discharge volume in low-speed zone and optimize pump discharge volume
in high-speed zone. Discharged oil from oil pump is transmitted to control valve. It is used as the oil of
primary and secondary pulley operation, the oil of clutch operation, and the lubricant for each part.

Forward clutch

The forward clutch is wet and multiple plate type clutch that consists of clutch drum, piston, drive plate,
and driven plate. It is a clutch to move the vehicle forward by activating piston hydraulically, engaging
plates, and directly connecting sun gear and input shaft.

Reverse brake

The reverse brake is a wet multiple-plate type brake that consists of transaxle case, piston, drive plate,
and driven plate. It is a brake to move the vehicle in reverse by activating piston hydraulically, engaging
plates, and fixing planetary gear.

Internal gear

The internal gear is directly connected to forward clutch drum. It is a gear that moves the outer edge of
pinion planet of planet carrier. It transmits power to move the vehicle in reverse when the planet carrier
is fixed.

Planet carrier

Composed of a carrier, pinion planet, and pinion shaft. This gear fixes and releases the planet carrier in
order to switch between forward and reverse driving.

Sun gear

Sun gear is a set part with planet carrier and internal gear. It transmits transmitted force to primary fixed
sheave. It rotates in forward or reverse direction according to activation of either forward clutch or re-
verse brake.

Input shaft

The input shaft is directly connected to forward clutch drum and transmits traction force from torque con-
verter. In shaft center, there are holes for hydraulic distribution to primary pulley and hydraulic distribution
for lockup ON/OFF.

Primary pulley

It is composed of a pair of pulleys (the groove width is changed freely in the axial direction) and the steel
belt. The groove width changes according to wrapping radius of steel belt and pulley from low status to
overdrive status continuously with non-step. It is controlled with the oil pressures of primary pulley and
secondary pulley.

Secondary pulley

Steel belt

Manual shaft

When the manual shaft is in the P position, the parking rod that is linked to the manual shaft rotates the
parking pole. When the parking pole rotates, it engages with the parking gear, fixing the parking gear. As
a result, the secondary pulley that is integrated with the parking gear is fixed.

Parking rod

Parking pawl

Parking gear

Output gear

The deceleration gears are composed of 2 stages: primary deceleration (output gear, idler gear pair) and
secondary deceleration (reduction gear, final gear pair). All of these gears are helical gears.

Idler gear

Reduction gear

Differential

Torque converter regulator
valve

Adjusts the feed pressure to the torque converter to the optimum pressure corresponding to the driving
condition.

Pressure regulator valve

Adjusts the discharge pressure from the oil pump to the optimum pressure (line pressure) corresponding
to the driving condition.

Torque converter clutch
control valve

Adjusts the torque converter engage and disengage pressures.

Manual valve

Distributes the clutch operation pressure to each circuit according to the selector lever position.

Secondary reducing valve

Reduces line pressure and adjusts secondary pressure.

Primary reducing valve

Reduces line pressure and adjusts primary pressure.

Pilot valve A

Reduces line pressure and adjusts pilot pressure to the solenoid valves listed below.
• Primary pressure solenoid valve
• Secondary pressure solenoid valve
• Select solenoid valve
• Line pressure solenoid valve

Pilot valve B

Reduces pilot pressure and adjusts pilot pressure to the torque converter clutch solenoid valve.

FLUID COOLER & FLUID WARMER SYSTEM : System Description

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.

SHIFT LOCK SYSTEM
SHIFT LOCK SYSTEM : System Description

INFOID:0000000012201097

• The shift lock is the mechanism provided to prevent quick start of a vehicle by incorrect operation of a drive

when the selector lever is in P position.

• Selector lever can be shifted from the P position to another position when the following conditions are satis-

fied.

- Ignition switch is ON.

- Stop lamp switch ON (brake pedal is depressed)

- Press the selector button.

[CVT: RE0F10D]

STRUCTURE AND OPERATION

When the brake pedal is not depressed with the ignition switch ON,

the shift lock solenoid (A) is OFF (not energized) and the solenoid

rod (B) is extended with spring.

The connecting lock lever (C) is located at the position shown in the

figure when the solenoid rod is extended. It prevents the movement

of the detent rod (D). The selector lever cannot be shifted from the P

position for this reason.

When brake pedal is depressed (selector lever operation allowed)

The shift lock solenoid (A) is turned ON (energized) when the brake

pedal is depressed with the ignition switch ON. The solenoid rod (B)

is compressed with the electromagnetic force. The connecting lock

lever (C) rotates when the solenoid rod is compressed. Therefore,

the detent rod (D) can be moved. The selector lever can be shifted to

other positions for this reason.

P POSITION HOLD MECHANISM (IGNITION SWITCH LOCK)

The shift lock solenoid (A) is not energized when the ignition switch

is in any position other than ON. The shift mechanism is locked and

P position is held. The operation cannot be performed from P posi-

tion if the brake pedal is depressed with the ignition switch ON when

the operation system of shift lock solenoid is malfunctioning. How-

ever, the lock lever (B) is forcibly rotated and the shift lock is

released when the shift lock release rod (C) is pressed from above.

The selector operation from P position can be performed.

CAUTION:

Use the shift lock release button only when the selector lever

cannot be operated even if the brake pedal is depressed with the ignition switch ON.

LIST OF CONTROL ITEMS AND INPUT/OUTPUT

*: If these input/output signals show errors, TCM activates the fail-safe function.

CVT CONTROL SYSTEM : Fail-safe

INFOID:0000000012201099

TCM has a fail-safe mode. The mode functions so that operation can be continued even if the signal circuit of

the main electronically controlled 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-safe mode. At this time, check the DTC code and perform

inspection and repair according to the malfunction diagnosis procedures.

Vehicle behavior

Conditions of vehicle

Control

When a wheel spin is detected, the engine output and gear ratio are limited and the line pressure is increased.
Limits engine output when a wheel spin occurs in any of right and left drive wheels.

Vehicle behavior in
control

If the accelerator is kept depressing during wheel spin, the engine revolution and vehicle speed are limited to
a certain degree.

Normal return condi-
tion

Wheel spin convergence returns the control to the normal control.
