| Primary regulator valve |
Regulates the pressure of oil discharged from the oil pump to the optimum pressure (line pressure) depending on the driving condition. |
| Front brake control valve |
During front brake engagement, regulates the line pressure to the optimum level (front brake pressure) and supplies to front brake. (Regulates the clutch pressure at 1st, 2nd, 3rd and 5th speed) |
| Modulator valve 1 |
Regulates the line pressure to create a certain pressure (pilot pressure) required for line pressure control, shifting control and lock-up control. |
| Modulator valve 2 |
Regulates the line pressure to create a certain pressure (pilot pressure) required for shifting control. |
| Forward brake control valve |
During forward brake engagement, regulates the line pressure to the optimum level (forward brake pressure) and supplies to forward brake. |
| High&low reverse clutch control valve |
During high&low reverse clutch engagement, regulates the line pressure to the optimum level (high&low reverse clutch) and supplies to high&low reverse clutch. (Regulates the clutch pressure at 1st, 3rd, 4th and 5th speed) |
| Input clutch control valve |
During input clutch engagement, regulates the line pressure to the optimum level (input clutch pressure) and supplies to input clutch. (Regulates the clutch pressure at 4th and 5th speed) |
| Direct clutch control valve |
During direct clutch engagement, regulates the line pressure to the optimum level (direct clutch pressure) and supplies to direct clutch. (Regulates the clutch pressure at 2nd, 3rd and 4th speed) |
| Transfer clutch control valve |
Regulates the line pressure to the optimum level (transfer clutch pressure) and supplies to transfer clutch. |
| Lock-up control valve |
Switches lock-up function between operation and release. Also provides smooth lock-up by continuously performing the lock-up operation. |
| Oil cooler bypass valve |
Bypasses redundant oil of the cooler circuit without sending it. |
| Line pressure relief valve |
Discharges redundant oil of the line pressure circuit. |
| Manual valve |
Distributes the line pressure to each circuit in accordance with each selector position. For the circuits where no line pressure is distributed, drain occurs. |
| Front brake oil pressure switch |
Detects problems in front brake oil pressure and switches to the fail safe mode if a problem is detected. |
| Forward brake oil pressure switch |
Detects problems in forward brake oil pressure and switches to the fail safe mode if a problem is detected. |
| Input clutch oil pressure switch |
Detects problems in input clutch oil pressure and switches to the fail safe mode if a problem is detected. |
| Direct clutch oil pressure switch |
Detects problems in direct clutch oil pressure and switches to the fail safe mode if a problem is detected. |
| High&low reverse clutch oil pressure switch |
Detects problems in high&low reverse clutch oil pressure and switches to the fail safe mode if a problem is detected. |
