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
Torque Converter Clutch Control Valve OperationNJAT0015S0303
AAT155A
Lock-up released
The OFF-duration of the torque converter clutch solenoid valve is
long, and pilot pressure is high. The pilot pressure pushes the end
face of the torque converter clutch control valve in combination with
spring force to move the valve to the left. As a result, converter
pressure is applied to chamber A (torque converter clutch piston
release side). Accordingly, the torque converter clutch piston
remains unlocked.
Lock-up applied
When the OFF-duration of the torque converter clutch solenoid
valve is short, pilot pressure drains and becomes low. Accordingly,
the control valve moves to the right by the pilot pressure of the
other circuit and converter pressure. As a result, converter pres-
sure is applied to chamber B, keeping the torque converter clutch
piston applied.
Also smooth lock-up is provided by transient application and
release of the lock-up.
OVERRUN CLUTCH CONTROL (ENGINE BRAKE
CONTROL)
NJAT0015S04Forward one-way clutch is used to reduce shifting shocks in down-
shifting operations. This clutch transmits engine torque to the
wheels. However, drive force from the wheels is not transmitted to
the engine because the one-way clutch rotates idle. This means the
engine brake is not effective.
The overrun clutch operates when the engine brake is needed.
