Variable Line Pressure Control
Description
- Form the most suitable line pressure according to the vehicle driving condition |
Special Features
- VFS (Variable Force Solenoid) valve (For varying line pressure) - Reducing valve added(Stabilize control pressure in shiftings) |
Effects
- Improved power transmission efficiency and fuel consumption |
Gear durability improvement and less-noisy gear development
Description
- Optimal gear transmission ratio design from analyzing gears |
Special Features
- Apply High-strength gear material - Gear teeth width increased - Planetary gear (3 pinions → 4 pinions) - Less-noisy gear development |
Effects
- Durability improvement - Reduction of noise level |
Case/Housing intensity reinforced
Description
- Case/Housing intensity reinforced |
Special Features
- Converter housing intensity reinforced(Ribs added and thickness increased) - Most suitable stiff reinforcement through analyzing |
Effects
- Intensity increased and banding vibration decreased - NVH Performance improvement |
New frictional material
Description
- Apply new frictional material for capacity and durability improvement |
Special Features
- SSP (Single Sided Plate) applied only on overdrive clutch and 2nd brake - Apply the next generation frictional material(BWA 6100/D 0880-88) |
Effects
- Thermal absorption capacity improvement - Energy capacity and durability improvement |
