AUTOMATIC TRANSAXLE SYSTEM

DESCRIPTION
The automatic transmission is a combination of 3-element 2-phase 1-stage torque converter and double shaft electrically-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.
