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.
