STRUCTURE AND OPERATION
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 wit h the oil pressures of primary pulley and secondary pulley.
Steel Belt
It is composed of multiple steel plates (A) and two steel rings (B)
stacked to a several number. The feature of this steel belt transmits
power with compression of the steel plate in contrast with transmis-
sion of power in pulling with a rubber belt. Friction force is required
with the pulley slope to transmit power from the steel plate. The force
is generated with the following mechanism:
Oil pressure applies to the secondary pulley to nip the plate. ⇒The
plate is pushed and extended outward. ⇒The steel ring shows with-
stands. ⇒Pulling force is generated on the steel ring. ⇒The plate of
the primary pulley is nipped between the pulley. ⇒Friction force is
generated between the steel belt and the pulley.
Therefore, responsibilities are divi ded by the steel plate that trans-
mits the power with compression and the steel ring that main tains necessary friction force. In this way, the
tension of the steel ring is distributed on the entire su rface and stress variation is limited, resulting in good
durability.
Pulley
The primary pulley (input shaft side) and the secondary pulley (output shaft side) have the shaft with slope
(fixed cone surface), movable sheave (movable cone surface that can move in the axial direction) and oil pres-
sure chamber at the back of the movable sheave.

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 tr ansmitted 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.

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.
Heater Thermostat
• The heater thermostat (1) is insta lled on the front part of transaxle
assembly.
• The heater thermostat open and close with set temperature.
SHIFT LOCK SYSTEM
SHIFT LOCK SYSTEM : System DescriptionINFOID:0000000009463986
The shift lever cannot be shifted from the “P” positi on unless the brake pedal is depressed while the ignition
switch is set to ON. The shift lock is unlocked by turn ing the shift lock solenoid ON when the ignition switch is
set to ON, the park position switch is turned ON (selec tor lever is in “P” position), and the stop lamp switch is
turned ON (brake pedal is depressed) as shown in the oper ation chart in the figure. Therefore, the shift lock
solenoid receives no ON signal and the shift lock remains locked if all of the above conditions are not fulfilled.
However, selector operation is allowed if the shift lock release button is pressed.
