 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 A/T 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 con-
verter and ATF cooling system.
Always follow the procedures under “Changing A/T Fluid” in the AT section when changing A/T fluid. Refer to
XX-XX, "*****"
, XX-XX, "*****".
Service Notice or PrecautionINFOID:0000000001696268
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 malfunction 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.
 A/T malfunction did not display evidence of damaged or worn internal parts, steel particles or clutch plate lin-
ing 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.
OBD SELF-DIAGNOSIS (FOR TYPE 1 ONLY)
 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 OD OFF indicator lamp or the malfunction indicator lamp (MIL). Refer to the table
on XX-XX, "*****"
for the indicator used to display each self-diagnostic result.
 The self-diagnostic results indicated by the MIL are automatically stored in both the ECM and TCM memo-
ries.
Always perform the procedure “HOW TO ERASE DTC” on XX-XX, "*****"
to complete the repair and
avoid unnecessary blinking of the MIL.
 The following self-diagnostic items can be detected using ECM self-diagnostic results mode* only when the
OD OFF indicator lamp does not indicate any malfunctions.
-PNP switch
- A/T 1st, 2nd, 3rd, or 4th gear function
*: For details of OBD, refer to XX-XX, "*****"
