Control valve pressure, function - GF27.60-P-3017CWQ

TRANSMISSION 722.9 in MODEL 204.0 up to Model Year 8 

The control valve supply pressure is drawn from the working pressure and is limited to a maximum pressure of 8 bar. 2 supply pressure regulating valves are used. Supply pressure regulating valve 1 supplies the following control solenoid valves:

• Working pressure control solenoid valve (Y3/8y1)
• Clutch control solenoid valve K2 (Y3/8y3)
• Multidisk brake control solenoid valve B2 (Y3/8y6)
• Torque converter lockup clutch control solenoid valve (Y3/8y8)

Supply pressure regulating valve 2 supplies the following control solenoid valves:

• Clutch control solenoid valve K1 (Y3/8y2)
• Clutch control solenoid valve K3 (Y3/8y4)
• Multidisk brake control solenoid valve B1 (Y3/8y5)
• Multidisk brake control solenoid valve B3 (Y3/8y7)

By using the supply pressure 1 regulating valve and supply pressure 2 regulating valve the control solenoid valve groups are isolated from each other and when there is no shift (via a gear) there is a reciprocal influencing of control solenoid valve groups.
