parts. Apply petroleum jelly to protect O-rings and seals, or
hold bearings and washers in place during assembly. Do not
use grease.
+Extreme care should be taken to avoid damage to O-rings,
seals and gaskets when assembling.
+After overhaul, refill the transaxle with new ATF.
+When the A/T drain plug is removed, only some of the fluid is
drained. Old A/T fluid will remain in torque converter and ATF
cooling system.
Always follow the procedures under ªChanging A/T Fluidº in the
AT section when changing A/T fluid. Refer to ªChanging A/T
Fluidº, AT-15.
Service Notice or PrecautionsNJAT0247FAIL-SAFENJAT0247S01The TCM has an electronic Fail-Safe (limp home mode). This allows the vehicle to be driven even if a major
electrical input/output device circuit is damaged.
Under Fail-Safe, the vehicle always runs in third gear, even with a shift lever position of ª1º, ª2º or ªDº. The
customer may complain of sluggish or poor acceleration.
When the ignition key is turned ªONº following Fail-Safe operation, O/D OFF indicator lamp blinks for about
8 seconds. (For GENERAL AND EXCEPT FOR EURO-OBD; ªSELF-DIAGNOSTIC PROCEDURE (WITHOUT
CONSULT-II)º, refer to AT-44 and for EURO-OBD; ªTCM SELF-DIAGNOSTIC PROCEDURE (No Tools)º, refer
to AT-63.)
Fail-Safe may occur without electrical circuit damage if the vehicle is driven under extreme conditions (such
as excessive wheel spin followed by sudden braking). To recover normal shift pattern, turn the ignition key
ªOFFº for 5 seconds, then ªONº.
The blinking of the O/D OFF indicator lamp for about 8 seconds will appear only once and be cleared. The
customer may resume normal driving conditions.
Always follow the ªWORK FLOWº [Refer to AT-73 (General and except for Euro-OBD), AT-78 (EURO-OBD).]
The SELF-DIAGNOSIS results will be as follows:
The first SELF-DIAGNOSIS will indicate damage to the vehicle speed sensor or the revolution sensor.
During the next SELF-DIAGNOSIS, performed after checking the sensor, no damages will be indicated.
TORQUE CONVERTER SERVICENJAT0247S02The torque converter should be replaced under any of the following conditions:
+External leaks in the hub weld area.
+Converter hub is scored or damaged.
+Converter pilot is broken, damaged or fits poorly into crankshaft.
+Steel particles are found after flushing the cooler and cooler lines.
+Pump is damaged or steel particles are found in the converter.
+Vehicle has TCC shudder and/or no TCC apply. Replace only after all hydraulic and electrical diagnoses
have been made. (Converter clutch material may be glazed.)
+Converter is contaminated with engine coolant containing antifreeze.
+Internal failure of stator roller clutch.
+Heavy clutch debris due to overheating (blue converter).
+Steel particles or clutch lining material found in fluid filter or on magnet when no internal parts in unit are
worn or damaged Ð indicates that lining material came from converter.
PRECAUTIONS
Precautions (Cont'd)
AT-9
Page 12 of 2898
The torque converter should not be replaced if:
+The fluid has an odor, is discolored, and there is no evidence of metal or clutch facing particles.
+The threads in one or more of the converter bolt holes are damaged.
+Transaxle failure did not display evidence of damaged or worn internal parts, steel particles or clutch plate
lining material in unit and inside the fluid filter.
+Vehicle has been exposed to high mileage (only). The exception may be where the torque converter clutch
dampener plate lining has seen excess wear by vehicles operated in heavy and/or constant traffic, such
as taxi, delivery or police use.
EURO-OBD SELF-DIAGNOSIS Ð EURO-OBD ÐNJAT0247S04+A/T self-diagnosis is performed by the TCM in combination with the ECM. The results can be read through
the blinking pattern of the O/D OFF indicator or the malfunction indicator (MI). Refer to the table on AT-55
for the indicator used to display each self-diagnostic result.
+The self-diagnostic results indicated by the MI are automatically stored in both the ECM and TCM memo-
ries.
Always perform the procedure ªHOW TO ERASE DTCº on AT-52 to complete the repair and avoid
unnecessary blinking of the MI.
+The following self-diagnostic items can be detected using ECM self-diagnostic results mode* only when
the O/D OFF indicator lamp does not indicate any malfunctions.
þ PNP switch
þ A/T 1st, 2nd, 3rd, or 4th gear function
*: For details of EURO-OBD, refer to EC-59, ªON BOARD DIAGNOSTIC SYSTEM DESCRIPTIONº.
+Certain systems and components, especially those related to EURO-OBD, may use a new style
slide-locking type harness connector.
For description and how to disconnect, refer to EL-6, ªHARNESS CONNECTORº.
Wiring Diagrams and Trouble DiagnosisNJAT0248When you read wiring diagrams, refer to the following:
+GI-11, ªHOW TO READ WIRING DIAGRAMSº
+EL-10, ªPOWER SUPPLY ROUTINGº
When you perform trouble diagnosis, refer to the following:
+GI-32, ªHOW TO FOLLOW TEST GROUP IN TROUBLE DIAGNOSISº
+GI-21, ªHOW TO PERFORM EFFICIENT DIAGNOSIS FOR AN ELECTRICAL INCIDENTº

Checking A/T FluidNJAT02281. Warm up engine.
2. Check for fluid leakage.
3. Before driving, fluid level can be checked at fluid temperatures
of 30 to 50ÉC (86 to 122ÉF) using ªCOLDº range on dipstick.
a. Park vehicle on level surface and set parking brake.
b. Start engine and move selector lever through each gear posi-
tion. Leave selector lever in ªPº position.
c. Check fluid level with engine idling.
d. Remove dipstick and note reading. If level is at low side of
either range, and fluid to the charging pipe.
e. Re-insert dipstick into charging pipe as far as it will go.
f. Remove dipstick and note reading. If reading is at low side of
range, add fluid to the charging pipe.
