Item

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.

Idler gear

Reduction gear

Final 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.
