I
Before proceeding with disassembly, thoroughly clean the out-
side of the transmission. It is important to prevent the internal
parts from becoming contaminated by dirt or other foreign mat-
ter.
I
Disassembly should be done in a clean work area.
I
Use lint-free cloth or towels for wiping parts clean. Common
shop rags can leave fibers that could interfere with the opera-
tion of the transmission.
I
Place disassembled parts in order for easier and proper
assembly.
I
All parts should be carefully cleaned with a general purpose,
non-flammable solvent before inspection or reassembly.
I
Gaskets, seals and O-rings should be replaced any time the
transmission is disassembled.
I
It is very important to perform functional tests whenever they
are indicated.
I
The valve body contains precision parts and requires extreme
care when parts are removed and serviced. Place disas-
sembled valve body parts in order for easier and proper
assembly. Care will also prevent springs and small parts from
becoming scattered or lost.
I
Properly installed valves, sleeves, plugs, etc. will slide along
bores in valve body under their own weight.
I
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.
I
Extreme care should be taken to avoid damage to O-rings,
seals and gaskets when assembling.
I
After overhaul, refill the transmission with new ATF.
I
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 when changing A/T fluid. Refer
to “Changing A/T Fluid”, AT-9.
Service Notice or Precautions
NMAT0004
FAIL-SAFE
NMAT0004S01
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
customer may complain of sluggish or poor acceleration.
When the ignition key is turned “ON” following Fail-Safe operation, POWER indicator lamp blinks for about 8
seconds. [For “SELF-DIAGNOSTIC PROCEDURE (Without CONSULT-II)”, refer to AT-37.]
The blinking of the POWER 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-46).
