Structure - The torque converter lockup PWM solenoid valve (Y3/6y6) is sealed off to the valve body of the 
shift plate (2a) by an O-ring (34) and a seal (arrow). See Fig. 63. The contact springs (32) on the PWM 
converter lockup solenoid valve (Y3/6y6) engage in a slot in the conductor tracks (33). The force of the contact 
spring (32) ensures safe contacts.

Modulating 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. 64. 

Modulating Pressure Regulating Solenoid Valve, Task 
 
To control the modulating pressure depending on the constantly changing operating conditions such as 
load/gear changes. 

Modulating Pressure Regulating Solenoid Valve, Design 
 
See MODULATING PRESSURE REGULATING SOLENOID VALVE, DESIGN. 

Modulating Pressure Regulating Solenoid Valve, Function 
 
The modulating pressure regulating solenoid valve (Y3/6y1) assigns a proportional pressure to the current 
which is controlled by the ETC control module (N15/3) according to the load.
