Pressure Modulation ▶
To provide a higher level of shift comfort and durability, the hydraulic pressure in the shift related
friction elements of the transmission must be matched accurately to the input torque to
transmission. This hydraulic pressure is composed of a hydraulically pre-set basic pressure and a
control pressure which is set by one of the variable bleed solenoids.
The transmission input torque can be directly calculated from the following operating parameters:
engine torque signals
engine speed or any signal transmitted from ECU through CAN lines
converter slip -
-
-
Separate pressure characteristics for each gear change make it possible to adapt precisely to the
particular shift operation.
5) Shift Mode Selection by TCU
The driver can select Standard (S) or Winter mode (W) with the mode switch. TCU automatically
changes the shift mode according to the transmission oil temperature, uphill or downhill gradient,
and altitude to keep the good driving conditions.
Standard Mode (S) ▶
Uphii and Downhill Mode ▶
Altitude Mode ▶ Standard Mode is selected when setting the mode switch in Standard (S) position with the gear

timing provides the optimized fuel economy and good driving conditions.
In this mode, the operating points of torque converter lock-up clutch and the shifting points are
adjusted according to the vehicle weight.
In this mode, the shifting points are automatically adjusted according to the altitude to compensate
the engine torque changes due to barometric pressure and temperature.

Winter Mode (W) ▶
Low Range Driving Mode ▶
Warm Up Mode ▶ When the Winter mode is selected, the second gear is engaged to start off the vehicle easily to
prevent wheel spin on slippery surfaces and WINTER mode indicator comes ON. The first gear is
not available in this mode.
When the vehicle is in 4L driving mode, the transmission uses a different shift mode to optimize
the low range driving. Similar to Winter mode, the first gear is not available.
This mode is normally used when the transmission oil temperature is below 20°C.

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) -

Front View
(1) Features
All gears use the helical type and high strength materials. 1.
The helical type gear prevents the axial gear missing and provides less noise. -
The semi-remote control type gear shift mechanism is used to prevent incorrect shifting.
To improve the shifting performance, 3-piece double cone is used for 1/2 shift. 2.
3.
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 gear engagement and
to provide silent gear engagement. -
The clutch release system is available to use CSC (Concentric Slave Cylinder) or Fork type
according to the vehicle model. 5.
