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.

Cruise Control ▶
When the cruise control is activated, the engine ECU requests the downshift to increase the
engine brake effect.PWM fan ON

the transmission is held in Neutral (N) gear until the oil temperature falls
below 120°C (Final protection)
