Item
Function
Torque converter
The torque converter is the device that increases the engine torque as well as the conventional
CVT and transmits it to the transaxle.
Oil pump
The efficiency of pump discharge rate has been increased at low-rpm and optimized at high-rpm
by adopting a vane-type oil pump controlled by the engine. Discharged oil from oil pump is trans-
mitted to the control valve. It is used as the oil of primary and secondary pulley operation and the
oil of clutch operation and the lubricant for each part.
Planetary gear
Perform the transmission of drive power and the switching of forward/backward movement.
Forward clutch
Reverse brake
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 star wheels are placed continuously and the belt is guided with the mul-
tilayer 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
Output gear
Reduction gear consists of primary deceleration (output gear and idler gear in pair) and second-
ary deceleration (reduction gear and final gear in pair). Each of them uses a helical gear.

Differential
Manual shaft
The parking rod rotates the parking pole and the parking pole engages with the parking gear
when the manual shaft is in P position. As a result the parking gear and the output axis are fixed.

HYDRAULIC CONTROL SYSTEM
System Diagram
INFOID:0000000003806354
System Description
INFOID:0000000003806355
The hydraulic control mechanism consists of the oil pump directly driven by the engine, the hydraulic control
valve that controls line pressure and transmission, and the input signal line.
LINE PRESSURE AND SECONDARY PRESSURE CONTROL
• When an input torque signal equivalent to the engine driving force is transmitted from the ECM to the TCM,
the TCM controls the line pressure solenoid valve and secondary pressure solenoid valve.
• Line pressure solenoid valve activates pressure regulator valve, and line pressure from oil pump is adjusted
for the optimum driving condition. Secondary pressure is controlled by lowering line pressure.
