The movable sheave slides on the shaft to change the gr oove width of the pulley. Input signals of engine load
(accelerator pedal opening), primary pulley speed and secondary pulley speed change the operation pres-
sures of the primary pulley and the secondary pulley, and controls the pulley groove width.
FINAL DRIVE AND DIFFERENTIAL
The deceleration gears are composed of 2 stages: primar y deceleration (output gear, idler gear pair) and sec-
ondary deceleration (reduction gear, final gear pa ir). All of these gears are helical gears.

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 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.
Parking rod
Parking pawl

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.

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

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.

REMOVAL
NOTE:
When removing components such as hoses, tubes/lines, etc. , cap or plug openings to prevent fluid from spill-
ing.
1. Remove front drive shaft. Refer to FAX-10, "Removal and Installation (LH)"
(LH) or FAX-12, "Removal and
Installation (RH)" (RH).
2. Remove differential side oil seal (1) using suitable Tool (A). CAUTION:
Be careful not to scratch transaxle case and converter
housing.
INSTALLATION
Installation is in the reverse order of removal.
CAUTION:
• Do not reuse differential side oil seal.
• Apply Genuine NISSAN CVT Fluid NS-3 to differential side oil seals.
• When inserting the drive shaf t, be sure to use Tool.

The chain belt consists of approximately 150 locker pins and
1,000 link plates . Chains are rotated by locker pins sandwiched by
pulleys. This produces tension difference in chains among pulleys.
Accordingly, the power is transferred by the tension.
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.
The movable sheave slides on the shaft to change the gr oove width of the pulley. Input signals of engine load
(accelerator pedal opening), primary pulley speed and secondary pulley speed change the operation pres-
sures of the primary pulley and the secondary pulley, and controls the pulley groove width.
