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

TRANSMISSION 722.9 in MODEL 164.1 /8, 216, 221, 251.0 /1 up to Model Year 8 

The control valve supply pressure is derived 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 (VGS) (Y3/8y1)
• Clutch control solenoid valve K2 (VGS)Y3/8y3
• Brake control solenoid valve B2 (VGS) (Y3/8y6)
• Torque converter lockup clutch control solenoid valve (VGS)Y3/8y8

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

• Clutch control solenoid valve K1 (VGS)Y3/8y2
• Clutch control solenoid valve K3 (VGS)Y3/8y4
• Brake control solenoid valve B1 (VGS) (Y3/8y5)
• Brake control solenoid valve B3 (VGS) (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.
