GF27.60-P-3017AHC control valve pressure, function
- Transmission 722.902/904/906/908


Function requirements
^ Circuit 87 ON
^ Circuit 61 ON

General
The control valve 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 1 regulating valve
^ Supply pressure 2 regulating valve

Supply pressure 1 regulating valve
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 2 regulating valve
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)

Using 2 supply pressure regulating valves means that the control solenoid valve groups are isolated from each other and when no gear is shifted a reciprocal influencing of the control solenoid valve groups occurs.
