D Position: 1ST Gear
The TCM controls the solenoid valves. The conditions of the solenoid valve and positions of the solenoid valve are as follows:
- The LR solenoid valve is turned off, and the LR pressure solenoid valve is moved to the left side.
- The 2nd solenoid valve is turned on, and the 2nd pressure solenoid valve remains in the right side.
- The UD solenoid valve is turned off, and the UD pressure solenoid valve is moved to the left side.
- The OD solenoid valve is turned on, and the OD pressure solenoid valve remains in the right side.
- The line pressure is supplied to the regulator valve and the fail-safe valve A.
- The line pressure is supplied to the each element (fail-safe valve B, switch valve, damper clutch control valve, LR solenoid valve, LR pressure control valve)
- he line pressure through the manual valve is supplied to the each element (DCCV, 2nd solenoid valve, 2nd pressure control valve, OD solenoid valve, OD pressure control valve, UD solenoid valve, UD pressure control valve).
- The fail-safe valve B moves to the left side by the line pressure.
- The switch valve moves to the left side by the line pressure.
- The line pressure is supplied to the DCCV, and TCM turns off the DCCSV, so the DCCV remains in the right side
- The line pressure is supplied to the LR pressure control valve and the LR solenoid valve, and TCM turns off the LR solenoid valve, so the line pressure is supplied to the LR brake through the switch valve and the fail-safe valve A.
- The line pressure is supplied to the UD pressure control valve and the UD solenoid valve, and TCM turns off the UD solenoid valve, so the line pressure is supplied to the UD clutch and the fail-safe valve B.
- The regulator valve moves to the left side by the line pressure through the manual valve, and the line pressure is supplied to the torque converter pressure control valve and the oil pump.
