Hydraulic operation – 2
Line pressure (1) becomes line pressure (4) as it passes through the manual valve. It then goes through line (20) to the 2nd clutch. Also, line pressure (1) goes to the modulator valve through the filter and becomes the modulator pressure (6). Modulator pressure (6) is not supplied to the 1 – 2, 2 – 3 and 3 – 4 shift valves. Line pressure (1) also flows to throttle valve B.
