DIRECT ELECTRIC SHIFT CONTROL OPERATION [FS5A-EL]

When Shifting N→D or N→R Shift
• When shifting N→D or N→R, the duty-cycle solenoid valves is driven to control the clutch engagement pressure optimally.
Up-Down Shift
• The clutch engagement pressure is directly controlled to be optimal by the duty-cycle solenoid valves.
• When shifting 2GR→ 3GR, 3GR→ 4GR, 4GR→ 5GR, 3GR→ 2GR, or 4GR→ 3GR, 5GR→ 4GR, the clutch pressures of engagement side and release side are controlled simultaneously. As a result, the clutch capacities of both clutches are controlled relatively when switching the clutches. This prevents sudden increases in engine speed and clutch interlocks during shifting, realizing smooth and responsive shifting.
