Shift Pressure Regulating Solenoid Valve, Location
In the supporting body of the electrical control unit (Y3/6) and pressed against the valve housing of the
shift plate (2a) by means of a leaf spring. See Fig. 66
.
Shift Pressure Regulating Solenoid Valve, Task
To control the shift pressure depending on the constantly changing operating conditions, such as
load/gear changes.
Shift Pressure Regulating Solenoid Valve, Design
See SHIFT PRESSURE REGULATING SOLENOID VALVE, DESIGN
.
Shift Pressure Regulating Solenoid Valve, Function
The shift pressure regulating solenoid valve (Y3/6y2) assigns a proportional pressure to the current which
is controlled by the ETC control module (N15/3) according to the load.

Operation - The shift pressure (p-S) is determines by the sh ift pressure regulating solenoid valve (Y3/6y2) and
the shift pressure regulating valve (24). See Fig. 68
. In addition, pressure from the multiple-disc clutch K2 (p-
K2) is also present at the annular surface (24a) of the sh ift pressure regulating valve (24). This reduces the shift
pressure in 2nd gear.
