Function

Torque converter

The torque converter is the device that increases the engine torque as well as the con-
ventional AT and transmits it to the transaxle.

Oil pump

The adoption of a trochoidal oil pump with a flow control valve actuated directly by the
engine enables the sufficient discharge from an oil pump in the low-rpm range and the
adequate discharge adjustments in the high-rpm range.

Planetary gear

Perform the transmission of drive power and the switching of forward/backward move-
ment.

Forward clutch

Reverse brake

Primary pulley

It is composed of a pair of pulleys (the groove width is changed freely in the axial direc-
tion) and the steel belt (the steel star wheels are placed continuously and the belt is guid-
ed 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 pul-
ley.

Secondary pulley

Steel belt

Output gear

Reduction gear consists of primary deceleration (output gear and idler gear in pair) and
secondary deceleration (reduction gear and final gear in pair). Each of them uses a he-
lical 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:0000000010113299

System Description

INFOID:0000000010113300

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.
