lAfter performing each TROUBLE DIAGNOSIS, perform
“DTC (Diagnostic Trouble Code) CONFIRMATION PROCE-
DURE”.
The DTC should not be displayed in the “DTC CONFIRMA-
TION PROCEDURE” if the repair is completed.
lBefore 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.
lDisassembly should be done in a clean work area.
lUse lint-free cloth or towels for wiping parts clean. Common
shop rags can leave fibers that could interfere with the operation
of the transaxle.
lPlace disassembled parts in order for easier and proper assembly.
lAll parts should be carefully cleaned with a general purpose, non-flammable solvent before inspection or
reassembly.
lGaskets, seals and O-rings should be replaced any time the transaxle is disassembled.
lIt is very important to perform functional tests whenever they are indicated.
lThe 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.
lProperly installed valves, sleeves, plugs, etc. will slide along bores in valve body under their own weight.
lBefore 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.
lExtreme care should be taken to avoid damage to O-rings, seals and gaskets when assembling.
lAfter overhaul, refill the transaxle with new ATF.
lWhen 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-13, "
A/T FLUID".
Service Notice or PrecautionsECS004Q3
FAI L-S AFE
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.
When the ignition key is turned “ON” following Fail-Safe operation, O/D OFF indicator lamp blinks for about 8
seconds. Refer to SELF-DIAGNOSTIC PROCEDURE(WITHOUT CONSULT-II)",AT- 2 7 3 , "
Diagnostic Proce-
dure Without CONSULT-II"(EXCEPT FOR EURO-OBD) or "TCM Self-diagnostic Procedure(NO TOOLS)",
AT- 5 1 , "
TCM SELF-DIAGNOSTIC PROCEDURE (NO TOOLS)"(EURO-OBD).
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 “WORK FLOW”, refer toAT-284, "
Work Flow"(EXCEPT FOR Euro-OBD) orAT-61, "Work
Flow"(Euro-OBD).
The SELF-DIAGNOSIS results will be as follows:
lThe first SELF-DIAGNOSIS will indicate damage to the vehicle speed sensor or the revolution sensor.
lDuring 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:
lExternal leaks in the hub weld area.
lConverter hub is scored or damaged.
lConverter pilot is broken, damaged or fits poorly into crankshaft.
lSteel particles are found after flushing the cooler and cooler lines.
lPump is damaged or steel particles are found in the converter.
