Structure - The modulating pressure regulating solenoid valve (Y3/6y1) had an interference fit and is sealed of
to the valve body of the shift plate (2a) by a seal (arrow). See Fig. 65. The contact springs (32) on the
modulating pressure regulating solenoid valve (Y3/6y1) engage in a slot in the conductor tracks (33). The force
of the contact spring (32) ensures safe contacts.

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.
