| Weight Reduction |
- Aluminum oil pump
- Pressed parts
- Retainer and hub of brakes and clutches
- Carrier of planetary gear set
|
| Better shift quality |
- Independent control of clutches and brakes enabled better control of hydraulic pressure and skiped shifts (4 to 2, 3 to 1)
- During N to D or N to R shift, feedback control adopted.
- When starting from Creep condition, reduction of shock.(Creep condition is controlled with 1st gear)
- Solenoid valve frequency is increased for more accurate control. 35Hz to 61.3Hz except DCCSV that is 35Hz and VFS that is 600Hz.
- HIVEC adoption for better shift feeling.
- Variable shift pattern.
