1. OVERVIEW
1) Characteristics of Transmission
Forward and Reverse gears are helical gear.
The clutch is operated by concentric slave cylinder (CSC).
To prevent the improper gear shift, semi-remote control system has been introduced.
To prevent the gears from engaging improperly, the synchronizer mechanisms and independent
interlock systems are installed on 1/2 gears, 3/4 gears, 5/6 gears and reverse gear.
The High-Force system for reverse gear shift has been introduced.
The synchronizer has three types: Triple (1, 2, 3, R), Double (5), Single (4, 6) -

4. IWE LOCKING HUB SYSTEM
1) Overview
The vacuum locking hub uses the IWE (Integrated Wheel End) system, and in this system, the vacuum
is generated only within the hub actuator.
It is structured to transmit power to the front section after the actuator hub is engaged following the
release of vacuum from the drive shaft end gear and the hub end gear

2) Vacuum System Related to 4WD
During 2WD mode, the vacuum
pressure from vacuum pump is
continuously transmitted to the
locking hub system.
This vacuum pressure pulls in the
locking hub actuator so that it will
not be engaged with the front end
hub gear.
22WD (applying vacuum pressure to hub
actuator) The vacuum pressure pulls in the
locking hub actuator so that it will not be
engaged with the front end hub gear.The vacuum pressure is released from the
hub actuator. At this time, the front hub end
gear is engaged.

In 4WD mode, the TCCU blocks the transferring of
vacuum pressure from vacuum pump to locking hub
by supplying the power to solenoid valve.
