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.
