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 chain
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
Chain belt
Instruction shaft
When the instruction shaft is in the P position, the parking rod that is linked to the instruction 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.
Instruction 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
INFOID:0000000010622730
CVT FLUID COOLER SCHEMATIC
COMPONENT DESCRIPTION
CVT Oil Warmer
• The CVT oil warmer
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.
CVT Fluid Cooler (Air Cooling Type)
• The CVT fluid cooler (air cooling type) is installed to the vehicle
front.
• CVT fluid is cooled by driving blast while driving the vehicle.
SHIFT LOCK SYSTEM
SHIFT LOCK SYSTEM : System Description
INFOID:0000000010622731
• The shift lock system prevents the select lever from being moved from “P” position to other positions due to
a driver's improper operation and prevents the occurrence of an abrupt start.
• Shift lock can be released when the following conditions are satisfied.
- Ignition switch is ON.
- Brake pedal is depressed. (Stop lamp switch is ON)
SHIFT LOCK OPERATION AT P POSITION
When brake pedal is not depressed (no selector operation allowed)

[CVT: RE0F10G]
STRUCTURE AND OPERATION
When the brake pedal is not depressed with the ignition switch ON,
the shift lock solenoid
is OFF (not energized) and the solenoid rod
is extended with spring.
The connecting lock lever
is located at the position shown in the
figure when the solenoid rod is extended. It prevents the movement
of the detent rod
. 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
is turned ON (energized) when the brake
pedal is depressed with the ignition switch ON. The solenoid rod
is compressed with the electromagnetic force. The connecting lock
lever
rotates when the solenoid rod is compressed. Therefore, the
detent rod
can be moved. The selector lever can be shifted to
other positions for this reason.
FORCIBLE RELEASE OF SHIFT LOCK
• When battery voltage decreases or an electrical/mechanical mal-
function occurs in the shift lock system, the selector lever cannot
be operated in “P” position. When shift lock release rod
is
pressed in this state, lock lever
is forcibly rotated, and then it
becomes possible to release shift lock.
• To release the shift lock forcibly and shift the selector lever from “P” position to other positions, follow the
steps below.
1.
Turn ignition switch OFF.
2.
Apply parking brake.
3.
Remove shift lock cover

Insert key
to finisher opening
and press the shift lock
release rod.
5.
Press the selector lever knob button and move the selector lever
from “P” position to other positions.
KEY LOCK SYSTEM
KEY LOCK SYSTEM : System Description
INFOID:0000000011009348
KEY LOCK MECHANISM
The key is not set to LOCK when the selector lever is not selected to P position. This prevents the key from
being removed from the key cylinder.
Key lock status
The slider
in the key cylinder
is moved to the left side of the fig-
ure when the selector lever is in any position other than P position.
The rotator
that rotates together with the key
cannot be rotated
for this reason. The key cannot be removed from the key cylinder
because it cannot be turned to LOCK
.
Key unlock status
The slider
in the key cylinder
is moved to the right side of the
figure when the selector lever is in P position and the finger is
removed from the selector button. The rotator
can be rotated for
this reason. The key
can be removed from the key cylinder
because it can be turned to LOCK
.
