MPV ES V6-2.5L DOHC (2001)
Operation
-
With the TCC control solenoid valve OFF, line pressure is applied to the right side of the TCC shift valve. It moves the valve to the left side by
overcoming the combined force of the spring and solenoid, reducing pressure. As a result, the hydraulic pressure (ATF) working on the torque
converter front chamber passes through the TCC shift valve, distributes the ATE, and inhibits TCC. With the TCC control solenoid valve ON, line
pressure is drained through the TCC control solenoid valve; the TCC shift valve moves to the right side due to the spring force. Consequently, the
hydraulic pressure applied to the torque converter front chamber is drained through the TCC, engaging TCC.
Coast Timing Valve
COAST TIMING VALVE
Outline
-
The coast timing valve controls the coasting clutch application timing.
Operation
-
Line pressure (1), distributed by the manual valve, constantly works on the right end of the valve and moves the valve to the left side by
overcoming spring force.
-
In 3GR, 2 - brake band release pressure (15) works on the left side of the valve, trying to push the valve to the right side. At the same time, the 2-4
brake band release pressure (15), which is also acting on the center of the valve, passes through the valve, engaging the clutch.
-
The orifice check valve controls the application timing.
