TRANSFER CASE
This function is only available when the speed signal from speed sensor is about to stop
(below 2 km/h).
This function is only available when clutch pedal is depressed (manual transmission) o
r
selector lever is selected to “N” position (automatic transmission).
(TCCU must recognize the clutch pedal signal or “N” signal.)
Change the 4WD switch in instrument panel from 4H to 4L.
“4WD LOW” warning lamp in meter cluster blinks during this process, then remains
when the shift is completed.
“4WD CHECK” warning lamp comes on when the system is defective. -

8. SYSTEM OPERATION
1) Transfer Case Control Unit (Tccu)
(1) 4WD Operation
TCCU is located under the front left seat and
permits the vehicle to shift from two-wheel
drive to four-wheel drive (and back shift)
according to drivers switch operation during
driving (For the shifting between 4WD HIGH
and 4WD LOW, stop the vehicle).
2H → 4H ▶
Change the 4WD switch in instrument panel from 2H to 4H.
This shift is available during driving.
“4WD HIGH” indicator in meter cluster comes on. -

1) Features
All gears use the helical type and high
strength materials. 3.
The helical type gear provides less noise.
The synchronizing devices are installed in
1/2, 3/4, 5/R gears. To prevent the double
engagement, the independent interlock
devices are installed. 4.
TSM54/52 transmission uses the inertia
lock type key to make smooth gea
r
engagement and to provide silent gea
r
engagement.
The clutch release system is available to
use CSC (Concentric Slave Cylinder) o
r
Fork type according to the vehicle model.
New Rexton uses the fork type
clutch release system.
The semi-remote control type gear shift
mechanism is used to prevent incorrect
shifting. 5.

1. OVERVIEW
1) Driving Elements
The driving elements consist of two flat surfaces machined to a smooth finish.
One of these is the rear face of the engine flywheel and the other is the clutch cover pressure
plate. The clutch pressure plate is fitted into a clutch steel cover, which is bolted to the flywheel.
2) Driven Elements
The driven element is the clutch disc with a splined hub which is free to slide lengthwise along
the splines of the input shaft. The driving and driven elements are held in contact by spring
pressure. This pressure is exerted by a diaphragm spring in the clutch cover pressure plate
assembly.
3) Operating Elements
The clutch control system consists of the clutch pedal, clutch master cylinder, concentric slave
cylinder. This system directly releases the clutch by using hydraulic pressure while the
conventional clutch system releases the clutch by using release lever and release fork. This
system provides higher efficiency than conventional clutch system, and its durability is superior.

This clutch system also requires to replace both clutch cover and disc when the disc need to
be replaced. However, for
disc re-usage, special zig set is not necessary.
This is different point with SAT system.

TORQUE ON DEMAND

2. GENERAL DESCRIPTION
TOD system means the full time 4WD system and the registered trade mark of Borg Warner.
TOD is an abbreviation of Torque On Demand.
TOD (Torque On Demand) system, which is superior than existing Full Time 4WD, checks the
road surface and vehicle conditions via various sensors and, subsequently, according to the
situations and conditions, distributes the most optimal driving force to front wheels and rea
r
wheels by activating the electro-magnetic clutch located inside of TOD Transfer Case.
TOD receives the speed signals from speed sensors installed in front axle and rear axle, the
TPS signals from engine, and the operating signals from ABS control unit via CAN.
Based on these data, TOD control unit controls the electro-magnetic clutch to distribute the
3:97 ~ 44:56 of driving force to front wheels and rear wheels.
The conventional system uses “FR driving” (theoretically, the 100 % of driving force is
transferred to rear wheels) on normal paved road.
When the system detects a slip in the rear wheels, a proper percentage of driving force is
transferred to front wheels.
TOD control unit receives the wheel speed signals from the speed sensors in propeller shaft o
f
transfer case and engine output information from the engine control unit.
TOD control unit changes the pressure force of the electromagnetic clutch based on the
analyzed data.
1) Distribution of Driving Force According to Road Surface
On normal road surface ▶
In vehicle with existing part time transfer case, when a driver turns the steering wheel to park in
the 4WD mode, the vehicle may halt sensation of tight corner braking phenomena. However, in
vehicle with TOD system, this phenomena does not occur and the driving force is properly and
automatically distributed.
On paved road with high speed ▶
Driving at high speed on roads such as highway mainly uses rear wheels as driving wheel.
At this moment, some of torques is also distributed to front wheels so that the vehicle could
maintain safe ground grab capacity against side winds and rain.
Distribution ratio: 15 % for front wheels and 85% for rear wheels.

TORQUE ON DEMAND
When turning on the road with low friction rate ▶
During cornering on roads such as unpaved, snowy, icy and muddy, ground grab capacity is
increased by distributing required torque and, at the same time, comfortable steering operation
is maintained by controlling the ground grab capacity at high level.
Distribution ratio: 30 % for front wheels and 70 % for rear wheels.
When climbing or starting off on the road with low friction rate ▶
In order to secure the maximum ground grab capacity and driving force during climbing o
r
starting off on the roads such as unpaved, snowy and icy road, the system controls the driving
force to distribute properly in full 4WD mode.
Distribution ratio: 44 % for front wheels and 56 % for rear wheels.
