Description
Hydraulic Flow (cont'd)
Position
Line pressure (1) becomes line pressure (4), (18), and (25) as it passes through the manual valve. Also, line pressure (1)
goes to the modulator valve through the filter and becomes modulator pressure (6). Modulator pressure (6) is supplied to
the 1-2 shift valve and 2-3 shift valve.
The 1-2 shift and 2-3 shift valves are moved to the left side because the shift control solenoid valve A is turned ON and B
is OFF by the TCM.
The line pressure (18) is supplied to the 3-4 shift valve, and moves the valve to the left side. Line pressure (4) becomes 1st
clutch pressure (10), and the 1st clutch is engaged.
Line pressure (4) becomes 1st-hold clutch pressure (16) via the 1-2 shift valve, 2-3 shift valve, 3-4 shift valve, and manual
valve, and the 1st-hold clutch is engaged.
NOTE: When used, "left" or "right" indicates direction on the hydraulic circuit.
