1. Structure & Technical highlights
2. 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
3. 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
4. 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
5. 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
