Full Lock-up
• Lock-up Control Solenoid Valve A: ON
• Lock-up Control Solenoid Valve B: ON
• Linear Solenoid Pressure: High
When the vehicle speed further increases, linear
solenoid pressure increases to high in accordance with
the linear solenoid which is controlled by the PCM.
The lock-up timing valve overcomes the spring force
and moves to the left side. Also, this valve closes the
fluid port leading to the left side of the lock-up control
valve.
Under this condition, modulator pressure in the left side
of the lock-up control valve had already been released
by the lock-up control solenoid valve B; the lock-up con-
trol valve is moved to the left side. As this takes place,
torque converter back pressure is released fully, causing
the lock-up clutch to be engaged fully.
NOTE: When used, "left" and "right" indicates direction
on the hydraulic circuit.
