After performing each TROUBLE DIAGNOSIS, perform
“DTC (Diagnostic Trouble Code) CONFIRMATION PROCE-
DURE”.
The DTC should not be displayed in the “DTC Confirmation
Procedure

AT-10
PRECAUTIONS

After performing each TROUBLE DIAGNOSIS, perform
“DTC (Diagnostic Trouble Code) CONFIRMATION PROCE-
DURE”.
The DTC should not be displayed in the “DTC Confirmation
Procedure” if the repair is completed.
Before proceeding with disassembly, thoroughly clean the out-
side of the transaxle. It is important to prevent the internal parts
from becoming contaminated by dirt or other foreign matter.
Disassembly should be done in a clean work area.
Use lint-free cloth or towels for wiping parts clean. Common
shop rags can leave fibers that could interfere with the operation
of the transaxle.
Place disassembled parts in order for easier and proper assembly.
All parts should be carefully cleaned with a general purpose, non-flammable solvent before inspection or
reassembly.
Gaskets, seals and O-rings should be replaced any time the transaxle is disassembled.
It is very important to perform functional tests whenever they are indicated.
The valve body contains precision parts and requires extreme care when parts are removed and serviced.
Place disassembled valve body parts in order for easier and proper assembly. Care will also prevent
springs and small parts from becoming scattered or lost.
Properly installed valves, sleeves, plugs, etc. will slide along bores in valve body under their own weight.
Before assembly, apply a coat of recommended ATF to all 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 “Changing A/T Fluid” in the AT section when changing A/T fluid. Refer
to “Changing A/T Fluid”, AT- 1 6 , "
A/T FLUID" .
Service Notice or PrecautionsECS004Q3
FAIL -SAF E
The 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 “1”, “2” or “D”. The cus-
tomer may complain of sluggish or poor acceleration.
Always follow the “WORK FLOW”, refer to AT- 2 5 5 , "
Work Flow" (EXCEPT FOR Euro-OBD) or AT- 6 1 , "Work
Flow" (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 SERVICE
The 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 — indicates that lining material came from converter.
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 — EURO-OBD —
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 lamp or the malfunction indicator (MI). Refer to the table on
AT- 4 5 , "
SELF-DIAGNOSTIC RESULT TEST MODE" 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 “HOW TO ERASE DTC” on AT- 4 2 , "
HOW TO ERASE DTC" to com-
plete 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.
–PNP switch
–A/T 1st, 2nd, 3rd, or 4th gear function
*: For details of EURO-OBD, refer to EC-52, "
ON BOARD DIAGNOSTIC (OBD) SYSTEM" .
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 PG-74, "
HARNESS CONNECTOR" .
