Description and operation
| Description |
Automatic transaxle control system relies on various measurements to determine the current control status and determine the necessary compensation values. These values are used to control the actuators and achieve the desired control output.
Operation
*PCSV-A : Overdrive clutch, Low&Reverse brake control solenoid valve
*PCSV-B : 24 brake control solenoid valve
*PCSV-C : Underdrive clutch control solenoid valve
*PCSV-D : Torque converter control solenoid valve
*SCSV-A : ON/OFF solenoid valve
