Manual HONDA INTEGRA 1998 4.G Owner's Manual

E Position
The flow of tluid through the torque converter circuit is the same as in L\l]position. The line pressure (1) becomes line
pressure (3) as it passes through the manual valve. Then line pressure (3) flows through the 1-2 shift valve to the servo
valve via the servo control valve, causing the shift fork shaft to be moved to the reverse position as in @ position.
However, the hydraulic pressure is not supplied to the clutches. Power is not transmitted.
NOTE: When used, "left" or "right" indicates direction on the hydraulic circuit.

Troubleshooting Procedures
Checking the Diagnostic Trouble Code (DTC)
with an OBD ll Scan Tool or th€ Honda PGM Tester
When the TCM senses an abnormality in the input or output systems, the lD,] indicator light in the gauge assembly will
blink. When the 16p Data Link Connector (DLC) (located under the dash on the passenger side) is connected to the OBD ll
Scan Tool or Honda PGM Taster as shown, the scan tool or tester will indicate the Diagnostic Trouble Code (DTC) when
the ignition switch is turned ON {ll}.
When the !r indicator light has been reported on, connect the OBD ll Scan Tool confirming to SAE J1978 or Honda PGM
Tester to the DLC (16P) behind the ashtray. Turn the ignition switch ON (ll) and observe the DTC on the screen ofthe OBD
ll Scan Tool or Honda PGM Tester. After determining the DTC, refer to the electrical system Symptom-to-Component
Chart on pages 14-54 and 14-55.
NOTE: SeetheOBDll ScanTool orHonda PGM Tester user's manual for specific instructions.
OBD-IlSCAN TOOL orHONDA PGM TESTER
Some PGM-Fl problems will also make the lol indicator light come on. After repairing the PGM-Fl system. disconnect the
BACK Up fuse (7.5 A) in the under-hood fuse/relay box for more than 10 seconds to reset the TCM memory, then recheck.
NOTE: Disconnecting the BACK UP fuse also cancels the radio anti-theft code, preset stations and the clock setting. Get
the customer's code number, and make note of the radio presets before removing the fuse so you can reset them

NOTES
See flushing procedure, page 14-172 and 173.
B.Set idle rpm in gear to specilied idle speed. lf still no good, adjust motor mounts as outlined in enginesection of service manual.
c.lf the large clutch piston O-.ing is broken, inspect the piston groove for rough machining.
D.lf the clutch pack is seized or is excessively worn, inspect the other clutches lor wear, and check the
orifice control valves and throttle valves for free mov€ment.
E.lf throttle valve B is stuck. insDect the clutches for wear.
lf the 1 - 2 shift valve is stuck closed, the transmission will not upshitt. lf stuck open, the transmissionhas no lst gear.
H.lf the 2-3 orilice control valve is stuck, inspect the 2nd and 3rd clutch packs for wear.
lf the orifice control valve is stuck. inspect the 3rd and 4th clutch packs for wear.
J.lf the clutch pressure control valve is stuck closed, the transmission will not shift out oI 1st gear.
lmproper alignment or main valve body and torque converter housing may cause ATF pump seizure.
The symptoms are mostly an rpm-related ticking noise or a high-pitched squeak.
lf the ATF strainer is clogged with particles of steel or aluminum, inspect the ATF pump and differentialpinion shaft. lf both are OK and no cause for the contamination is found, replace the torque converter.
M.lf the 1st clutch feed pipe guide in the right side cover is scored by the mainshaft, inspect the ball bear-
ing lor 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.Replace the mainshaft if the bushing for the 4th feed pipe is loose or damaged.lf the 4th feed pipe is damaged or out of round, replace the right side cover.Replace the sub-shaft il the bushing for the 1st-hold teed pipe is loose or damaged.lf the 1st-hold teed pipe is damaged or out of round, replace it.
Replace the mainshaft iI the bushing for the lst feed pipe is loose or damaged.lf the 1st leed pipe is damaged or out of round, replace it.
A worn or damaged sprag clutch is mostly a result of shifting the transmission in El or LDll position
while the wheels rotate in reverse, such as rocking the vehicle in snow.
P.Inspect the trame for collision damage.
Inspect lor damage and wear:1. Reverse selector gear teeth chamfers.2. Engagement teeth chamfers of countershaft 4th and reverse gear.
3. Shift fork for scuff marks in center.4. Differential pinion shaft tor wear under pinion gears.
5. Bottom of 3rd clutch for swirl marks.Replace items 1 . 2, 3 and 4 iI worn or damaged. lf transmission makes clicking, grinding or whirringnoise, also replace mainshaft 4th gear, reverse idler gear, and countershatt 4th gear in addition to '1,
2,3or4.It differential pinion shalt is worn, overhaul differential assembly, and replace ATF strainer, and thoroughly
clean transmission, tlush torque conveder, cooler and lines.lf bottom ot 3rd clutch is swirled and transmission makes gear noise, replace the countershaft and final
onven qear.
R.Be very careful not to damage the torque converter housing when replacing the main ball bearing. You
may also damage the ATF pump when you torque down the main valve body. This will result in ATFpump seizure if not detected. Use proper tools.
S.Install the main seal llush with the torque converter housing. lf you push it into the torque converterhousing until it bottoms out. it will block the fluid return passage and result in damage.
T.Harsh downshifts when coasting to a stop with zero throttle may be caused by a bent-in throttle valve
retainer/cam stopper. Throttle cable adjustment may clear this problem.
Throttle cable adjustment is essential tor proper operation ol the transmission. Not only does it affectthe shift points if misadjusted, 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 torqueinput into the transmission and may cause clutch slippage. A cable adjusted too short will result in toohiqh throttle pressure which may cause harsh shifts, erratic shifts and torque converter hunting.
