1 - 3. ON/OFF (drive/park/reverse) solenoid valve: In the Previous SBC (Shift By Cable) method, TGS lever and the automatic transmission is connected by shift cable. then Driver's P/R/N/D shift will is delivered mechanically linked. For this function, park release actuator and park position valve operation solenoid is added, the vehicle is always parked when the power is OFF.
SBW (Shift By Wire) system shift by the electronic transmission PRND (SOL valve) instead of cables.
4. Torque converter control solenoid valve: The torque converter control solenoid valve (T/CON_VFS) is installed on the valve body and this is the variable force solenoid (VFS) valve that controls the hydraulic pressure of torque converter indirectly.
5. Line pressure control solenoid valve: The line pressure control solenoid valve (LP_VFS) is installed on the valve body and PCM/TCM adjusts the line pressure according to the driving conditions through the line pressure solenoid value to reduce the engine load. The line pressure control solenoid valve (LP_VFS) is the variable force solenoid (VFS) valve.
6. 8LR brake control solenoid valve: 8LR brake control solenoid valve is attached to the valve body. This variable force solenoid valve directly controls the hydraulic pressure inside the 8LR brake.
7. 6 clutch control solenoid valve: 6 clutch control solenoid valve is attached to the valve body. This variable force solenoid valve directly controls the hydraulic pressure inside the 6 clutch.
8. 27 brake control solenoid valve: 27 brake control solenoid valve is attached to the valve body. This variable force solenoid valve directly controls the hydraulic pressure inside the 27 brake.
9. 35R clutch control solenoid valve: 35R clutch control solenoid valve is attached to the valve body. This variable force solenoid valve directly controls the hydraulic pressure inside the 35R clutch.
10. 4 & OD clutch control solenoid valve: 4 & OD clutch control solenoid valve is attached to the valve body. This variable force solenoid valve directly controls the hydraulic pressure inside the 4 & OD clutch.
11. UD clutch control solenoid valve: UD clutch control solenoid valve is attached to the valve body. This variable force solenoid valve directly controls the hydraulic pressure inside the UD clutch.
