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.

Checking A/T FluidECS004Q7
1. Warm up engine.
2. Check for fluid leakage.
3. Before driving, fluid level can be checked at fluid temperatures
of 30 to 50°C (86 to 122°F) using “COLD” 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 “P” 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.
Do not overfill.
4. Drive vehicle for approximately 5 minutes in urban areas.
5. Re-check fluid level at fluid temperatures of 50 to 80°C (122 to 176°F) using “HOT” range on dipstick.
6. Check fluid condition.
lIf fluid is very dark or smells burned, refer to AT section for
checking operation of A/T. Flush cooling system after repair of
A/T.
lIf A/T fluid contains frictional material (clutches, bands, etc.),
replace radiator and flush cooler line using cleaning solvent
and compressed air after repair of A/T. Refer toCO-12,
"RADIATOR",CO-15, "RADIATOR (ALUMINUM TYPE)",,.
Changing A/T FluidECS004Q8
1. Warm up A/T fluid.
2. Stop engine.
3. Drain A/T fluid from drain plug and refill with new A/T fluid.
Always refill same volume with drained fluid.
4. Run engine at idle speed for five minutes.
5. Check fluid level and condition. Refer to “Checking A/T Fluid”. If fluid is still dirty, repeat steps 2 through 5.

HOW TO PERFORM TROUBLE DIAGNOSES FOR QUICK AND ACCURATE REPAIR
A good understanding of the malfunction conditions can make troubleshooting faster and more accurate. In
general, each customer feels differently about a problem. It is important to fully understand the symptoms or
conditions for a customer complaint.
Make good use of the two sheets provided, “INFORMATION FROM CUSTOMER” (AT- 5 7 , "
Information from
Customer") and “DIAGNOSTIC WORKSHEET” (AT-58, "Diagnostic Worksheet"), to perform the best trouble-
shooting possible.
5.oFor self-diagnosis NG items, inspect each component. Repair or replace the damaged parts.AT-50, "Diag-
nostic Proce-
dure Without
CONSULT-II"
6.oPerform all ROAD TEST and re-mark required procedures.AT-69, "Road
Te s t"
7.oPerform DTC CONFIRMATION PROCEDURE for following MIL indicating items and check out NG items.
Refer to "EC-XX", “Emission-related Diagnostic Information”.EC section

Refer to the Symptom Chart when you perform the procedures. (The chart also shows some other possible
symptoms and the component inspection orders.)AT-86,
