STRUCTURE AND OPERATION

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 A/T fluid temperature is high.

Heater Thermostat

The heater thermostat (1) is installed on the front part of transaxle

assembly.

gear, and others. Also includes a parking mechanism that mechanically fixes secondary pulley when selector

lever is shifted to the “P” position.

POWER TRANSMISSION

“P” position

• Traction force from input shaft is not transmitted to primary pulley because forward clutch and reverse brake

are not engaged and run idle.

• Torque from the wheels is not transmitted to secondary pulley because secondary pulley is mechanically

fixed when parking pole that is linked with selector lever is engaged with parking gear that is integrated with

secondary pulley.

STRUCTURE AND OPERATION

Planetary gear

“R” position

• Traction force from input shaft rotates sun gear in opposite direction of input shaft rotation because reverse

brake is engaged and planetary gear is fixed.

• Therefore primary pulley rotates in opposite direction of input shaft rotation and traction force output is in

opposite direction rotation.

STRUCTURE AND OPERATION

Planetary gear

“D” position

• Traction force from input shaft rotates sun gear via forward clutch in the same direction of input shaft

because forward clutch is engaged.

• Therefore primary pulley rotates in the same direction of input shaft rotation and traction force output is in the

same direction rotation.

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 distribu-
tion for lockup ON/OFF.

STRUCTURE AND OPERATION

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 steel plates are placed continuously and the belt is guided with the multilayer steel rings on both 
sides). 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.

Shift control valve

Controls the line pressure that is applied to the primary pulley according to the stroke difference between 
the step motor and primary pulley.

Secondary valve

Reduces the line pressure and adjusts the secondary pressure.

Clutch regulator valve

Adjusts the clutch operating pressure according to the driving conditions.

Manual valve

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

Select control valve

Engages when selected. Adjusts the forward clutch pressure and reverse brake pressure.

Select switch valve

Performs switching control of the torque converter clutch solenoid valve control pressure when lock-up 
is engaged/disengaged, and when the forward/reverse clutches (forward clutch and reverse brake) are 
engaged/disengaged.

Step motor

• Step motor changes step by turning 4 coils ON or OFF according to signal from TCM.
• By changing step, step motor controls outward flow and inward flow of line pressure to primary pulley, 

determines the primary pulley position, and controls gear ratio.
