Inspection
Remove the cylinder head cover.
lnspect the timing belt for c.acks and oil or coolant
soaking. Replace the belt if it is oil or coolant
soaked. Remove any oil or solvent that gets on the
belt.
lnspect thisarea for wear.
After inspecting, retorque the crankshaft pulley bolt
to 177 N.m (18.0 kgnm, 130 lbf.ft).
Install the cylinder head cover (see page 6-32).

Tension Adjustment
NOTE:
. Always adjust the timing belt tension with the engine
coto.
. Always rotate the crankshaft counterclockwise when
viewed from the pulley side. Rotating it clockwise
may result in improper adiustment of the belt ten-
sion.
'1. Remove the cylinder head cover
2. Set the No. 1 piston at TDC (see page.6-12).
3. Rotate the crankshaft five or six revolutions to set
the belt.
Set the No. 1 piston at TDC.
Loosen the adjusting bolt 1/2 turn (180') only.

is at top dead center (TDC). Align the groove on the
timing belt drive pulley to the pointer on the oil pump.

lf the camshaft pulleys are not positioned at TDC,
remove the timing belt. adjust the position following
the procedure on page 6-11. then reinstall the timing
belt.
Installthe cylinder head cover (see page 6-32).
After installation, adjust the tension on each belt.

Description
Hydraulic Flow (cont'd)
4th Gear llQ! or E Posirion)
As the speed of the vehicle reaches the prescribed value. shift control solenoid valve A is turned OFF by the pCM,
Shift control solenoid valve B remains OFF. Modulator pressure (6) flows to the left end of the 1-2 shift valve and theleft end of the 3-4 shift valve. Modulator pressure (64) in the left end of the 1-2 shift valve equals modulator pressure(68) in the right end of the 1-2 shift valve. The 1-2 shift valve remains at left side by the tension of the valve spring.The 3-4 shift valve is moved to the right side by modulator pressure (6A). The 3-4 shift valve covers the pon to the 3rdclutch and uncovers the port to the 4th clutch as this valve is moved to the right side, The 4th clutch pressure (41)from the 3-4 shift valve becomes 4th clutch pressure (40) at the manual valve. The 4th clutch pressure (40) is appliedto the 4th clutch, and the 4th clutch is engaged.
Fluid flows by way of:- Line pressure (4) + CPB Valve - Line Pressure (5) + l-2 Shift Valve - Line Pressure {5) * 2-3 Shift Valve- Line Pressure (5) + 3-4 Shift Valve - 4th Clutch Pressure (41) + Manual Valve - 4th Clutch Pressure (40)+ 4th Clutch
The hydraulic pressure also flows to the lst clutch. However, no power is transmitted because of the one-wav clutch.
NOTE:
. When used, "lelt" or " tight" indicates direction on the hydraulic circuit.. The hydrau lic circuit shows the '97 - 98 models (7 positions); the '99 - 0O models (6 oositions) issimilar.

. 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.

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.
