The fail-safe valve B moves to the right side by the line pressure through the UD pressure control valve and the line pressure through the OD pressure control valve. The pressure is supplied to the fail-safe valve A through the OD pressure control valve, but the fail-safe valve A does not move to the right side The line pressure is supplied to the DCCV and the DCCSV, and TCM(PCM) turns on the DCCSV, and the DCCV moves to the left side, and the damper clutch is operated. The line pressure is supplied to the UD pressure control valve and the UD solenoid valve, and TCM(PCM) turns off the UD solenoid valve, so the line pressure is supplied to the UD clutch and the fail-safe valve B. The line pressure is supplied to the OD pressure control valve and the OD solenoid valve, and TCM(PCM) turns off the OD solenoid valve, so the line pressure is supplied to the OD clutch and the fail-safe valve A/B and the switch valve. The switch valve moves to the right side by the line pressure through the OD pressure control valve. The regulator valve moves to the left side by the pressure through the manual valve and the pressure through the switch valve, and the line pressure is more supplied to the oil pump.

D position : 4th gear The TCM(PCM) 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 on, and the LR pressure solenoid valve remains in the right side. The 2nd solenoid valve is turned off, and the 2nd pressure solenoid valve is moved to the left side. The UD solenoid valve is turned on, and the UD pressure solenoid valve remains in the right side. The OD solenoid valve is turned off, and the OD pressure solenoid valve is moved to the left side. The line pressure through the manual valve is supplied to the regulator valve and the fail-safe valve A. The line pressure is supplied to each element (fail-safe valve B, switch valve, DCCV, LR solenoid valve, LR pressure control valve). The line pressure through the manual valve is supplied to each element (DCCSV, 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 right side by the line pressure through the 2nd pressure control valve and the line pressure through the OD pressure control valve. The line pressure through the OD pressure control valve is supplied to the fail-safe valve A, and the fail-safe valve A moves to the right side by the line pressure through the fail-safe valve B and the line pressure through the OD pressure control valve. The line pressure is supplied to the DCCV and the DCCSV, and TCM(PCM) turns on the DCCSV, so DCCV moves to the right side, and the damper clutch is operated.
