Operation
If a shift solenoid valve (Y3/6y3, Y3/6y4, Y3/6y5) is actuated via the ETC control module (N15/3), it opens and directs the control pressure (p-SV) to the command valve assigned (31).

The respective shift solenoid valve (Y3/6y3, Y3/6y4, Y3/6y5) remains actuated and therefore open until the shift process is completed. The shift pressure (p-SV) to the command valve is reduced to zero as soon as the respective shift solenoid valve (Y3/6y3, Y3/6y4, Y3/6y5) is switched de-energized.
