transmission oil HONDA INTEGRA 1994 4.G Owner's Manual

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.

NOTES
A.See flushing procedure, page l4-168 and 169.
B.Set idle rpm in gear to specitied idle speed. lf still no good, adiust motor mounts as outlined in engine
section of service manual.
lf the large clutch piston O-ring is broken, inspect the piston groove for rough machining.
lf the clutch pack is seized or is excessively worn, inspect the other clutches Jor wear, and check the
orifice control valves and throttle valves for free movement.
E.It throttle valve B is stuck, inspect the clutches for wear.
lf the 1-2 shift valve is stuck closed, the transmission will not upshift. lI stuck open, the transmission
has no lst gear.
H.lf the 2-3 orifice control valve is stuck, inspect the 2nd and 3rd clutch packs for wear.
ll the orifice cont.ol valve is stuck, inspect the 3rd and 4th clutch packs for wear.
lf the clutch Dressure control valve is stuck closed, the transmission will not shilt out of 1st gear.
K.improper alignment or main valve body and torque converter housing may cause oil pump seizure. The
symptoms ale mostly an rpm-related ticking noise or a high-pitched squeak.
L.ll the ATF strainer is ctogged with panicles of steel or aluminum, inspect the oil pump and ditferential
pinion shaft. lt both are OK and no cause lor the contamination is found, replace the torque converter.
M.lf the 1st clutch feedpipe guide in the right side cover is scored by the mainshaft, inspect the ball bear-
ing for excessive movement in the transmission housing. lf OK. replace the right side cover as it is dent-
ed. The O-ring under the guide is probably worn.
N.ReDlace the mainshstt if the bushing for the 4th feedpipe is loose or damaged.
It the 4th feedpipe is damaged or out ot tound, replace the right side cover'
Replace the subjshaft it thtbushing for the 1st-hold Jeedpipe is loose or damaged.
lf the 1st-hold feedpipe is damaged or out of round, replace it.
Replace the mainshaft if the bushing lor the 1st feedpipe is loose or damaged.
lf the lst feedpipe is damaged or out ot round, replace it.
o.A *o- r, da."s"d "p-g clutch is mostly a result of shifting the transmission in El or Lq! position
while the wheels rotate in reverse, such as rocking the car in snow.
P.InsDect the frame for collision damage.
o.Inspect for damage or wear:
1. Reverse selector gear teeth chamfers.
2. Engagement teeth chamters of countershaft 4th and reverse gear.
3. Shift fork for scutt marks in center.
4. Differential Dinion shaJt for wear under pinion gears.
5. Bottom of 3rd clutch for switl marks.
Replace items 1 , 2, 3 and 4 it worn or damaged. lf transmission makes clicking, grinding or.whirring
noise, atso replace mainshaft 4th gear and reverse idler gear and countershaft 4th gear in addition to
1,2,3ot4.lf ditiersntial Dinion shaft is worn, overhaul differential assembly, and replace ATF strainel, and thoroughly
clean transmission, tlush torque convertet, cooler and lines.
lf bottom of 3rd clutch is swirled and transmission makes gear noise, replace the countershaft and tinal
driven gear.
R.Be wry careful not to dsmage the torque converter housing when replacing the main ballbearing. You
may al;o damage the oil pump when you torque down the main valve body. This will result in oil pump
seizure it not detected. Use proper tools.
qInstall the main seal tlush with the torque converter housing, lf you push it into the torque converter
housing until it bottoms out. it will block the oil return passage and result in damage.
T,Harsh do\/vnshiJt"\./l,'hen coasting to a stop with zero th.ottle may be caused by a bent-in throttle valve
retainer/cam stopper. Throttle cable adjustment may clear this problem.
ifuitle cable adjustment is essential for proper operation of the transmission. Not only does it affect
the shift points if misad,usted, but also the shift quality and lock-up clutch operation'
A cable adjusted too long will result in throttle pressure being too low for the amount of engine torque
input into ihe trsnsmission and may cause clutch slippage. A cable adjusted too short will result in too
hi;h throttle pressure which may cause harsh shitts, erratic shrfts and torque con

Stall Speed
CAUTION:
a To plevent transmission damage, do not test stall speed fot mote than 1O seconds at a time.a Do not shift the level while raising th€ engine speed.a Be sure to remove the pressure gauge belot€ testing stall speed.
1. Engage the parking brake and block all four wheels.
2. Connect the tachometer, and start the engine.
3. Make sure the A/C switch is OFF.
4. After the engine has warmed up to normal operating temperature (the cooling lan comes on), shift into ft position.
5. Fully depress the brake pedal and accelerator for 6 to 8 seconds. and note engine speed.6. Allow 2 minutes for cooling, then repeat the test in [, fDil and @ positions.
NOTE:
a Stall speed tests should be used lor diagnostic purposes only.. Stall speed should be the same in E, tr. tr and @ positions.

S!@ ro prevent iniury to tace and eyes, always
wear safety glas$es or a tace shield when using the trans-
mission flusher.
NOTE: This procedure should be performed before rein-
stalling the transmission.
1. Check tool and hoses for wear or cracks before
using.
lf wear or cracks are found, replace the hoses be-
fore using.
2. Using the measuring cup, tillthe tank with 21 ounces
{approximately 213 lulll of biodegradable tlushing
fluid (J35944-20). Do not substitute with any other
fluid.
Follow rhe handling procedure on the fluid container.
Secure the tlusher filler cap and pressurize the tank
with compressed air to between 550-829 kPa(5.6-8.45 kgt/cm,, 80- 120 psi),
NOTE: The air line should be equipped with a water
trap to ensure a dry air system.
Hang the tool under the vehicle.
Attach the discharge hose of the tank to the return
line of the transmission cooler using a clamp.
Connect the drain hose to the inlet line of the trans-
mission cooler using a clamp. Securely clamp the op-posite end of the drain hose to a bucket or floor drain.

8. Turn on the flusher water valve so water will tlow
through the oil cooler for 1O seconds. lf water does
not flow through the oil cooler it is completely
plugged, cannot be flushed, and must be replaced.
9. Depress the trigger to mix the tlushing lluid into the
water tlow. Use the wire clip to hold the trigger
oown.
10. While flushing with the water and flushing fluid for
2 minutes. turn the air valve on for 5 seconds every
15-20 seconds to create a surging action.
AIR PRESSURE:
MAX 829 kPa (8.45 kgt/cm,, 12O psi)
1 1. Turn the water valve off. Release the trigger, then
reverse the hoses to the cooler so you can flush in
the opposite direction. Repeat steps 8 through 1O.
12. Release the trigger and allow water only to rinse the
cooler with water for one minute.
13. Turn the water valve off and turn off the water
supply.
14. Turn the air valve on to dry the system out with air
for two full minutes or until no moisture is visible
leaving the drain hose.
CAUTION: Residual moisture in the oil cooler 01
pipes can damage the transmission.
15. Remove the flusher trom the cooler line. Attach the
drain hose 10 a oil container.
16. lnstallthe transmission and leave the drain hose at-
tached to the cooler line.
