AT
●After 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.
●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 AT-13, "
Changing A/T Fluid" when changing A/T fluid.
Service Notice or PrecautionsECS007N8
FA I L - S A F 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.
When the ignition key is turned “ON” following Fail-Safe operation, O/D OFF indicator lamp blinks for about 8
seconds. Refer to AT- 2 5 0 , "
Diagnostic Procedure Without CONSULT-II" (EXCEPT FOR EURO-OBD) or AT-
51, "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 to AT- 2 5 9
(EXCEPT FOR EURO-OBD) or AT- 6 0 (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.

InstallationECS007T5
1. Check drive plate runout.
CAUTION:
Do not allow any magnetic materials to contact the ring
gear teeth.
●If this runout is out of allowance, replace drive plate with ring
gear.
2. When connecting torque converter to transaxle, measure dis-
tance “A” to be certain that they are correctly assembled.
3. Install torque converter to drive plate.
●With converter installed, rotate crankshaft several turns
to check that transaxle rotates freely without binding.
