GF27.60-P-3017N Function of Regulating Valve Pressure




GF27.60-P-3017N Function of Regulating Valve Pressure
TRANSMISSION 722.9 in MODEL 171.4, 203, 230 up to Model Year 2008
TRANSMISSION 722.9 in MODEL 209, 211, 215, 219, 220
TRANSMISSION 722.9 in MODEL 463.303 /340 /341 up to 31.5.12

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.
