DescriptionINFOID:0000000003848973
TCM selects the gear ratio using the engine load (throttle position), the primary pulley revolution speed, and
the secondary pulley revolution speed as input signals. Then it changes the operating pressure of the primary
pulley and the secondary pulley and changes the groove width of the pulley.

MECHANICAL SYSTEM
Component Description
INFOID:0000000003806353
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.
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. 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. Parking rod
