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 supply pressure regulating valve 1 and supply pressure regulating valve 2 the control solenoid valve groups are isolated from each other and, in the event of any shift operations (via a gear), none of the control solenoid valve groups has an effect on any other.
