1994 HONDA INTEGRA roll

E Position
As the engine turns, the oil pump also starts to operate. Automatic transmission fluid (ATF) is drawn from (99) and dis-
charged into (1 ). Then, ATF pressure is controlled by the regulator valve and becomes line pressure ( 1 ). The torque con-
verter inlet pressure (92) enters (94) of torque converter through the orifice and discharges into {90}.
The torque converter check valve prevents the torque converter pressure from rising'
Under this condition, the hydraulic pressure is not applied to the clutches.

Description
Hydraulic Flow (cont'd)
3rd Speed
The tlow of fluid up to the 1-2 and 2 3 shift valves is the same as in 2nd speed. As the speed of the car reaches
the prescribed value, the shift control solenoid valve B is turned off {shilt control solenoid valve A remains on). The
2-3 shift valve is then moved to the left, uncovering the oil port leading to the 3rd clutch. Since the 3-4 shitt valve
is moved to the right to cover the oil port to the 4th clutch, the 3rd clutch is turned on.
Fluid tlows by way of:- Line pressure l4l - 1-2 shift valve - 23 Shift Valve * 3rd ctutch pressure (31) - 3-4 shift valve(not controlled) 3rd Clutch Pressure (3O) - 3rd Clutch
The hydraulic pressure also flows to the l st clutch. However, no power is transmitted because of the one-way clutchas in the 2nd speed.

In E position in 2nd, 3rd and 4th, and @ position in 3rd, pressurized fluid is drained from the back of the torque con-
verter through an oil passage, causing the lock-up piston to be held against the torque converter cover. As this takes
place, the mainshaft rotates at the same speed as the engine crankshaft. Together with hydraulic control, the TCM op-
timized the timing ot the lock-up system. Under certain conditions, the lock-up clutch is applied during deceleration, in
3rd and 4th sDeed.
The lock-up system controls the range of lock-up according to lock-up control solenoid valves A and B, and throttle valve B.
When lock-up control solenoid valves A and B activate. modulator pressure changes. Lock-up control solenoid valves
A and B are mounted on the torque converter housing, and are controlled by the TCM.

Valve Body
Repair
NOTE: This repair is only necessary il one or more of
the valves in a valve body do not slide smoothly in their
bores. You may use this procedure to lree the valves in
the valve bodies.
1. Soak a sheet of #600 abrasive paper in ATF for
about 30 minutes.
2. Carefully tap the valve body so the sticking valve
drops out of its bore.
CAUTION: lt may be necessary to use a small
screwdiiver to pry the the valve lree. Be carelul not
to sclatch the bore with ihe sc.ewdliver.
3. Inspect the valve tor any scuff marks. Use the ATF-
soaked # 600 pagper to polish off any burrs that are
on the valve, than wash the valve in solvent and dry
it with compressed air.
4. Roll up halt a sheet oI ATF-soaked paper and insert
it in the valve bore of the sticking valve.
Twist the paper slightly, so that it unrolls and fits
the bore tightly, then polish the bore by twisting the
paper as you push it in and out.
CAUTION: The valve body is aluminum and doesn't
require much polishing to remove any burs.
W
5.
6.
7.
Remove the #600 paper and thoroughly wash the
entire valve body in solvent, then dry with com-
perssed air.
Coat the valve with ATF then drop it into its bore.
It should drop to the bottom o{ the bore under its
own weight. lf not. repeat step 4 then retest.
VALVE BODY
Remove the valve and thoroughly clean it and the
valve body with solvent. Dry all parts with com
pressed air, then reassemble using ATF as a
lubricant.
