Inspeclthe a utomatic transmission problem (s)accordingto the DTC (s)indicated with code m700.
(DTC)*: The DTCS in the parentheses are the codes the E indicator light indicates (blinks) when the service cnecK connec-tor is connected with the sDecialtool {SCS service connector).
NOTE: WhentheOBDll Scan Tool orHonda PGM Tester indicates the DTC(S) for the automatic transmission control sys-
tem, the scan tool or tester also indicates code P0700 simultaneously. Code P0700 means detection of some automatic
transmission problem on the PGM-Fl control system.
lf the self-diagnostic E indicator light does not blink. perform an inspection according to the table below.
NOTE:
. lf a custombr describes the symptom for code P1706 (6), P0725 (11) or P0715 (15), it will be necessary to recreate the
symptom by test-driving, then recheck the DTC,. Sometimes the E indicator light and the Malfunction Indicator Lamp (MlL) may come on simultaneously. lf so, check
the PGM-Fl system according to the DTC, then reset the memory by removing the BACK UP fuse in the under-dash
fuse/relay box for more than l0 seconds. Drive the vehicle for several minutes at a speed over 30 mph(50 km/h). then recheck the DTC.
. 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.

Road Test

4. Accelerate to about 35 mph (57 km/h) so the transmission is in 4th, then shitt from E position to E position.
The vehicle should immediately begin slowing down from engine braking.
CAUTION: Do noi shitt lrom I or $ position to E or E position 8t speeds over l0o mph (160 km/h); you may
damage the transmission.
5. Check for abnormal noise and clutch slippage in the following positions,
E {1st Gear} Position-1. Accelerate from a stop at fullthrottle. Check that there is no abnormal noise or clutch slippage.-2. Upshifts should not occur with the shift lever in this position.
E (2nd Gear) Position-1. Accelerate from a stop atfull throttle. Check that there is noabnormal noiseorclutch slippage.-2. Upshifts and downshifts should not occur with the shift lever in this position.
E (Reverse) Position
Accelerate from a stop at tull throttle, and check for abnormal noise and clutch slippage.
6. Test in E (Parking) Position
Park vehicle on slope {app.ox. 16'}, apply the parking brake, and shift into E position. Release the brake; the vehicle
should not move.
