Description
Hydraulic Flow (cont'd)
or Position
3. 3rd Gear
As the speed of the vehicle reaches the prescribed value, shift solenoid valve B is turned OFF by means of the PCM.
Shift solenoid valve A remains ON. The modulator pressure (6B) flows to the right ends of the 1-2 shift valve and the 2-
3 shift valve. The 2-3 shift valve is moved to the left side by the modulator pressure (6B). The 2-3 shift valve uncovers
the port to allow the line pressure (5) to the 3-4 shift valve as this valve is moved to the left side. The line pressure (5')
becomes the 3rd clutch pressure at the 3-4 shift valve. The 3rd clutch pressure (30) is applied to the 3rd clutch, and the
3rd clutch is engaged.
Hydraulic pressure also flows to the 1st clutch and 2nd clutch. However, no power is transmitted because of the one-
way clutches.
NOTE:
• When used, "left" or "right" indicates direction on the hydraulic circuit.
• The hydraulic circuit is for '96 - '98 models. On '99 - 01 models, the 2nd accumulator is different.
