TSM54/52 transmission is designed to link the gear ratio, installation dimensions and shapes
with current T5 transmission and BTRA automatic transmission. It provides maximum
drivability by the optimized engine torque and gear ratio.
TSM54/52 transmission uses linkage type shift elements directly connected to the
transmission. It prevent the transmission from shifting to the reverse gear from 5th gea
r
when shifting to reverse gear. It also prevents the break and wear. 1.

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.
