Structure - The shift solenoid valves (Y3/6y3, Y3/6y4, Y3/6y5) are sealed to the valve housing of the shift
plate (2a) by two O-rings (34, 35) (2a). See Fig. 48.

The contact springs (32) on the shift solenoid valves (Y3/6y3, Y3/6y4, Y3/6y5) engages in a slot in the
conductor tracks (33). The force of the contact spring (32) ensures safe contacts.
