TOROUE CONVERTER
No Lock-up
. Lock-up Control Solenoid Valve A: OFF
. Lock-up Control Solenoid Valve B: OFF
. Linear Solenoid Pressure: High
The pressurized fluid regulated by the modulator works
on both ends of the lock-up shift valve. Under this condi-
tion, the pressures working on both ends of the lock-up
shift valve are equal. and the lock-up shift valve is
moved to the right side by the tension of the valve
spring. Fluid trom the ATF pump will flow through the
left side of the lock-up clutch to the torque converter; the
lock-up clutch is OFF.
NOTE: When us€d, "|eft" and "right" indicates direction
on the hydraulic circuit.

Lock-up System (cont'dl
a
a
Half Lock-up
Lock-up Control Solenoid Valve A: ON
Lock-up Control Solenoid Valve B: Duty Operation
OFF - ON
Linear Solenoid Pressure: Low
The PCM switches solenoid valve A on to release modu-
lator pressure in the left cavity of the lock-up shift valve.
Modulator pressure in the right cavity of the lock-up
shift valve overcomes the spring force, and the lock-up
shift valve is moved to the left side.
Line pressure is then separated into the two passages to
the torque converter; torque converter inner pressure
enters into right side to engage the lock-up clutch, and
torque convener back Dressure enters into left side to
disengage the lock-up clutch.
Back pressure (F2) is regulated by the lock-up control
valve, whereas the position of the lock-up timing valve
is determined by linear solenoid pressure and tension of
the valve spring. Also the position of the lock-up control
valve is determined by the back pressure of the lock-up
control valve. torque converter pressure (regulated by
the torque converter check valve), and modulator pres-
sure (determined by the lock-up control solenoid valve
B). The PCM switches lock-up control solenoid valve B
on and off rapidly (duty operation), under certajn condi-
tions, to regulate back pressur€ (F2) and lock the torque
convertef.
NOTE: When used, "left" and "right" indicates direction

. 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.
