PRESSURE CONTROL SOLENOID B CONSTRUCTION/OPERATION [FS5A-EL]
id051721284900
• The pressure control solenoid B is a duty-cycle type solenoid.
• A duty-cycle type solenoid adjusts the clutch pressure and brake pressure by switching ON/OFF at 50 Hz (20 ms cycle).
1GR to 4GR or 5GR
• When driving in 1GR to 4GR or 5GR, the supply port (line pressure) opens and is engaged with the output port (4-5 duty solenoid pressure).
• As a result, hydraulic pressure is supplied to the hydraulic passage for the 4-5 duty solenoid.
Shifted from 4GR to 5GR or from 5GR to 4GR
• When the gear is shifted from 4GR to 5GR or from 5GR to 4GR, the line pressure is regulated to the optimum hydraulic pressure for the driving condition by energizing for a specified time.
