•  When shifting N→D or N→R, the pressure control solenoid is driven to control the clutch engagement pressure optimally.

•  The clutch engagement pressure is directly controlled to be optimal by the duty-cycle solenoid valves.

•  When shifting 2GR→3GR, 3GR→4GR, 3GR→2GR, or 4GR→3GR, 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.
