Electronic Control System
DESCRIPTION
The electronic control system used in the new generation auto transaxle is far superior to the previous systems. This
system is able to adopt a variable shift pattern for smooth and problem free shifting.
A solenoid valve is applied to each of the clutches and brakes and is independently controlled. Feedback control and
correction control is performed in all gears as well as utilization of mutual control system to increase shift feeling.
The torque converter damper clutch uses a partial lock up and full lock - up system. An additional control method called
the HIVEC system (neural network) is adopted to increase shift feeling.

Sports Mode
Sports Mode Switch
Sports mode allows the manual up- shift and downshift with the accelerator pedal is depressed. The prompt response
and shift would be obtained due to the continuous shifting without cutting of driving power. The shifting time is also
decreased about 0.1sec during up- shift, 0.2sec during downshift. As the selector lever is pushed upward or downward
one time, the gear is up shifted or downshifted by one gear.

Controller Area Network (CAN)
Previously, for different computers in the vehicle to share the same information, each signal required a different pin
and wiring. However, with the introduction of a CAN system, only two lines are required to achieve the same function.
The information is in digital format. This method does not use an integrated ECM.

Input signals to TCM(PCM) through ‘CAN communication’
- Engine rpm, TPS signal
- A/CON signal, Engine coolant temperature
- Quantity of intake airflow, Vehicle speed
- Shift holding signal (FTCS ON)
Output signals from TCM(PCM) through ‘CAN communication’
- Request signal for torque reduction
- ATF temperature, TCM(PCM) type, TCM(PCM) error or not
- Damper clutch ON, OFF / Gear position

Description
The automatic transmission is a combination of 3 - element 2 - phase 1 - stage torque converter and double shaft
electrocally - controlled unit which provides 4 speeds forward and 1 reverse. To improve the efficiency of power
transmission, the line pressure control was changed applying “Variable Force Solenoid (VFS) valve” on this model.
However, adopting VFS on this model, the line pressure is variably changed according to TPS and the vehicle speed,
this will enable more improved efficiency of power transmission and fuel consumption.
Characteristics
Some of the characteristics include:
▶Different power transfer
▶Different component layout
▶New shift logic(HIVEC) to improve shift feeling
▶Position of Valve Body
▶Variable shift pattern
▶Communication protocol and method
▶Step gate type shift lever.

Torque converter and shaft
The torque converter consists of an impeller(pump), turbine and stator assembly in a single unit. The pump is
connected to the engine crankshaft and turns as the engine turns. This drawing force is transmitted to the turbine
through the oil which is recycled by the stator.
The transmission has two parallel shafts ; the input shaft and the output shaft. Both shafts are in line with the engine
crankshaft. The input shaft includes the overdrive clutch, reverse clutch, underdrive clutch, one way clutch, 2ND brake,
low&reverse brake, overdrive planetary carrier, output planetary carrier and transfer drive gear. The output shaft
includes the transfer driven gear.
CLUTCHES
The gear changing mechanism utilizes three multi- disc clutches. The retainers of these clutches are fabricated from
high- precision sheet metal for lightness and ease of production. Also, more responsive gearshifts at high engine
speeds are achieved by a pressure- balanced piston mechanism that cancels out centrifugal hydraulic pressure. This
mechanism replaces the conventional ball check valve.
UNDERDRIVE CLUTCH
The underdrive clutch operates in 1st, 2nd, and 3rd gears and transmits driving force from the input shaft to the
underdrive sun gear(A).
The components comprising the under clutch are as illustrated below.
