• Better and smoother shift quality.
• In order to prevent ATF leakage from the valve body or each elements, the exhaust ports have been grouped into only one with an addition of a check ball.
• If a failure occurs in its electric control, the switch valve and fail safe valve is able to move to enable 3rd speed drive or reverse.
• The hydraulic system consists of oil pump, regulator valve, solenoid valves, pressure control valve and valve body.
• In order to control the optimal line pressure and in-prove the efficiency of power transmission according to maximize the efficiency of the oil pump, VFS (Variable Force Solenoid) valve has been added in the valve body hydraulic circuit.
