Working pressure, function - GF27.60-P-3013CWQ
TRANSMISSION 722.9 in MODEL 204.0 up to Model Year 8
The oil pressure produced by the oil pump is converted into working pressure by the working pressure regulating valve. The level of working pressure depends on the position of the regulating valve and therefore on its geometry.
The position of the working pressure regulating valve is influenced by the working pressure control solenoid valve (Y3/8y1) depending on load and gear. All other pressures required for the transmission control are derived from the working pressure.
