Structure 
The shift pressure regulating solenoid valve (Y3/6y2) has  an interference fit and is sealed off to the valve body  
of the shift plate (2a) by a seal (arrow). See   Fig. 175
.  
The contact springs (32) on the shift   pressure solenoid valve (Y3/6y2) engage in a slot in the conductor tracks  
(33). The force of the contact sp  ring (32) ensures safe contacts.

Operation 
The shift pressure (p-S) is determines by the shift pressure regulating solenoid valve (Y3/6y2) and the shift 
pressure regulating valve (24). See Fig. 177. In addition, pressure from the multiple-disc clutch K2 (p-K2) is 
also present at the annular surface (24a) of the shift pressure regulating valve (24). This reduces the shift 
pressure in 2nd gear.

Operation 
The RPM sensors are pressed against the transmission housing (51) by a spring (49) which is held against the 
valve housing of the shift plate (2a). See .Fig. 179
 This ensures a defined distance between the RPM sensors 
and the exciter ring (50). RPM sensor 2 (Y3/6yn2) records the speed of the front planetary gear carrier via the 
inner multiple-disc carrier of the front multiple-disc clutch (K1c).
