Line pressure control | • Using linear type pressure control solenoids, adjusts line pressure according to engine load condition and vehicle driving condition.
Shift control | • Detects engine load condition and vehicle speed, and switches to the most suitable gear position according to the preset shift diagram. • In D range, automatically switches between POWER and NORMAL modes according to accelerator pedal depressing speed.
Clutch pressure direct control (Direct electric shift control) | • With duty-cycle type shift solenoids A, B, and C, directly performs electronic control for clutch engagement pressure according to engine load condition and vehicle driving condition.
Feedback control | • Performs real-time feedback correction for clutch engagement pressure to achieve target shifts. • Performs optimal correction for clutch engagement pressure to reduce changes in engine performance and/or elapsed transaxle.
Engine-transaxle total control | • Optimally controls engine output torque when shifting. • Operates optimal clutch engagement pressure corresponding to engine output torque.
TCC control | • According to preset TCC point, performs TCC operation via smooth TCC.
Slope mode control | • Changes the shift point to prevent frequent shifting up/down when climbing hills and descending hills.
On-board diagnostic system | • Detects and/or memorizes failure of input/output part and transaxle condition.
