Component DescriptionINFOID:0000000003848923
Item Function
Torque converterThe torque converter is the device that increases the engine torque as well as the con-
ventional AT and transmits it to the transaxle.
Oil pumpThe 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

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

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

Removal and InstallationINFOID:0000000003849101
REMOVAL
1. Remove front drive shafts. Refer to FAX-16, "Exploded View".
2. Remove differential side oil seals (1) using a flat-bladed screw-
driver (A).
CAUTION:
Be careful not to scratch transaxle case and converter
housing.
INSTALLATION
Note the following, and install in the reverse order of removal.
 Drive each differential side oil seal evenly using a commercial ser-
vice tool so that differential side oil seal protrudes by the dimension
(C) respectively.
Unit: mm (in)
NOTE:
Differential side oil seal pulling direction is used as the reference.
CAUTION:
 Never reuse differential side oil seals.

Item Function
Torque converterThe torque converter is the device that increases the engine torque as well as the conventional
CVT and transmits it to the transaxle.
Oil pumpThe 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.
