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, the lock-up shift valve is moved to
the right side by the tension of the valve spring alone.
The fluid from the ATF pump will flow through the left
side of the lock-up clutch to the torque convener; that is,
the lock-up clutch is in OFF condition.
NOTE: When used, "left" or "right" indicates direction
on the hydraulic circuit.

. Lock-up Control Solenoid Valve A: ONLock-up Control Solenoid Valve 8: Duty Operation
OFF - ONLinear Solenoid Pressure: Low
The PCM switches the solenoid valve A on to release themodulator pressure in the left cavity of the lock_up shiftvalve. The modulator pressure in the right cavity of thelock-up shift valve overcomes the spring force; thus thelock-up shift valve is moved to the left side.The line pressure is then separated into the two pas-sages to the torque converter:
Torque Converter Inner pressure: enters into rightsade to engage lock-up clutch
Torque Converter Back pressure: enters into left sideto diseogage lock-up clutchThe back pressure (F2) is regulated by the lock-up con-trol valve, whereas the position of the lock-up timingvalve is determined by the linear solenoid Dressure andtension of the valve spring. Also the position of the lock_up control valve is determined by the back pressure ofthe lock-up control valve, torque converter pressure reg_ulated by the torque converter check valve, and modula_tor pressure determined by the lock-up control solenoidvalve B. The PCM switches the lock-up control solenoidvalve B on and off rapidly {duty operation} under certainconditions to regulate the back pressure (F2) to lock thetorque convener properly.
NOTE: When used, "left" or "right" indicates directionon the hvdraulic circuit.

Park Mechanism
The park mechanism locks the transmission by engaging the park pawl with the park gear which is integral with the sec-ondary drive gear' The secondary drive gear engages with the secondary driven gear which engages wit-h the final drivengear.
shifting to E position causes the park cone (installed at the end of the park rod) to press the park pawl onto the park gear.Even if the end of the park pawl rides on the top of the park gear teeth, slight movement of the vehicle will cause the parkpawl and the park gear to mesh with each other completely because the park cone receives the tension from the park rodspring The park pawl receives the tension (which acts to separate the park pawl from the park gear) from the park pawlspring.

Reassembly (cont'dl
8. Fit the inboard joint onto the driveshaft, and note
these items:
. Reinstall the inboard joint onto the driveshaft by
aligning the marks on the inboard joint with the
marks on the rollers.
. Hold the driveshaft so that the inboard joint
points up to prevent it from falling off.
Adjust the length of the driveshafts to the figure
below, then adjust the boots to halfway between
full comDression and full extension. The ends of the
boots seat in the groove of the driveshaft and joint.
