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.
Slip control*2
• When the accelerator pedal is fully released for deceleration, power transfer efficiency has been improved through a slip lockup control on the torque converter set under a specified range of conditions (speed or throttle angle). As a result, fuel economy, emission performance, and ride comfort have been improved.
Slope mode control
• Changes the shift point to prevent frequent shifting up/down when climbing hills.
On-board diagnostic system
• Detects and/or memorizes failure of input/output part and transaxle condition.
Manual mode shift control*1
• Shifts to selected gear position by manual shifting of the selector lever forward and back.
