MPV DX V6-2.5L DOHC (2000)
Operation
-
Torque converter pressure (23) generated by the pressure regulator valve is constantly applied to the right end of the converter relief valve. Spring
force, however, moves the valve to the right side.
-
When torque converter pressure (23) increases, it overcomes spring force and pushes the converter relief valve to the left side. The pressure (23) is
drained and maintained under a specified level.
2-3 Timing Valve
2-3 TIMING VALVE
Outline
-
The 2-3 timing valve controls the 2-4 brake release pressure and 3-4 clutch pressure during 2GR - 3GR shifting.
Operation
-
When shifting from 2GR to 3GR, 3-4 clutch application pressure (18) works on the left side of the valve, trying to move it to the right side.
-
When the throttle valve opening angle is small, low 3-4 clutch application pressure (18) pushes the valve to the right, causing 2-4 brake release
pressure (15) to pass through the valve and to work on the coasting clutch.
-
When the throttle valve opening angle is large, high 3-4 clutch application pressure (18) pushes the valve to the right, allowing 2-4 brake release
pressure (15) to work on the coasting clutch.
Pressure Regulator Valve
PRESSURE REGULATOR VALVE
Outline
-
The oil pressure regulator valve adjusts the line pressure generated by the oil pump to match driving conditions.
