Shift valve pressure in general 

The shift valve pressure is derived from the control valve pressure, is regulated at the shift valve pressure regulating valve and is then applied to the following components:

• 1-2 and 4-5 shift solenoid valve (Y3/6y3)
• 3-4 shift solenoid valve (Y3/6y4)
• 2-3 shift solenoid valve (Y3/6y5)
• Torque converter lockup PWM solenoid valve (Y3/6y6)
• 3-4 and 2-3 shift pressure shift valve

The shift valve pressure controls the command valves via the upshift/downshift solenoid valves.
