or Position
1. 1st Gear
The flow of fluid through the torque converter circuit is the same as in
the manual valve, the modulator valve, the line pressure control valve and the throttle valve. The line pressure (1)
becomes the modulator pressure (6) at the modulator valve, and the line pressure (4) at the manual valve. The modula-
tor pressure (6) flows to the left ends of the 1-2 shift valve and the 3-4 shift valve because shift solenoid valve A is
turned OFF and B is turned ON by the PCM. The 1-2 shift valve is moved to the right side, and uncovers the port to
