STRUCTURE AND OPERATION

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 plates are placed continuously and the belt is guided 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 pulley.

Secondary pulley

Steel belt

Manual shaft

When the manual shaft is in the P position, the parking rod that is linked to the manual shaft rotates the 
parking pole. When the parking pole rotates, it engages with the parking gear, fixing the parking gear. 
As a result, the secondary pulley that is integrated with the parking gear is fixed.

Parking rod

Parking pawl

Parking gear

Output gear

The deceleration gears are composed of 2 stages: primary deceleration (output gear, idler gear pair) and 
secondary deceleration (reduction gear, final gear pair). All of these gears are helical gears.

Idler gear

Reduction gear

Differential 

Torque converter regulator 
valve

Adjusts the feed pressure to the torque converter to the optimum pressure corresponding to the driving 
condition.

Pressure regulator valve

Adjusts the discharge pressure from the oil pump to the optimum pressure (line pressure) corresponding 
to the driving condition.

Torque converter clutch 
control valve

Adjusts the torque converter engage and disengage pressures.

Shift control valve

Controls the line pressure that is applied to the primary pulley according to the stroke difference between 
the step motor and primary pulley.

Secondary valve

Reduces the line pressure and adjusts the secondary pressure.

Clutch regulator valve

Adjusts the clutch operating pressure according to the driving conditions.

Manual valve

Distributes the clutch operation pressure to each circuit according to the selector lever position.

Select control valve

Engages when selected. Adjusts the forward clutch pressure and reverse brake pressure.

Select switch valve

Performs switching control of the torque converter clutch solenoid valve control pressure when lock-up 
is engaged/disengaged, and when the forward/reverse clutches (forward clutch and reverse brake) are 
engaged/disengaged.

Step motor

• Step motor changes step by turning 4 coils ON or OFF according to signal from TCM.
• By changing step, step motor controls outward flow and inward flow of line pressure to primary pulley, 

determines the primary pulley position, and controls gear ratio.

INFOID:0000000012200880

The TCM has an electrical fail-safe mode. In this mode TCM is operator even if there is an error in a main

electronic control input/output signal circuit. 

DESCRIPTION

When a malfunction is detected in each sensor, switch, solenoid or others, this function provides control to

minimize reduction of drivability so that durability of transmission assembly can be acquired.
