PRECAUTIONS
After performing each TROUBLE DIAGNOSIS, perform “DTC
(Diagnostic Trouble Code) Confirmation Procedure”.
If the repair is completed the DTC should not be displayed in
the “DTC Confirmation Procedure”.
 Always use the specified brand of ATF. Refer to MA-9, "
Fluids and Lubricants".
 Use lint-free paper not cloth rags during work.
 After replacing the ATF, dispose of the waste oil using the methods prescribed by law, ordinance, etc.
 Before proceeding with disassembly, thoroughly clean the out side of the transmission. It is important to pre-
vent the internal parts from becoming cont aminated by dirt or other foreign matter.
 Disassembly should be done in a clean work area.
 Use lint-free paper or towels for wiping parts clean. Common shop rags can leave fibers that could interfere
with the operation of the transmission.
 Place disassembled parts in order for easier and proper assembly.
 All parts should be carefully cleansed with a general purpose, non-flammable solvent before inspection or
reassembly.
 Gaskets, seals and O-rings should be replaced any time the transmission 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 s lide 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 transmission with new ATF.
 When the A/T drain plug is removed, only some of t he ATF is drained. Old ATF 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
AT- 11 , "
Changing A/T Fluid", AT- 11 , "Checking A/T Fluid".
Service Notice or PrecautionINFOID:0000000001327125
ATF COOLER SERVICE
If ATF contains frictional material (clutches, bands, etc. ), or if an A/T is repaired, overhauled, or replaced,
inspect and clean the A/T fluid cooler mounted in the radiat or or replace the radiator. Flush cooler lines using
cleaning solvent and compressed air after repair. For A/T fluid cooler cleaning procedure, refer to AT-13, "
A/T
Fluid Cooler Cleaning". For radiator replacement, refer to CO-13 (for VQ35DE), CO-40 (for VK45DE).
OBD-II SELF-DIAGNOSIS
 A/T self-diagnosis is performed by the TCM in comb ination with the ECM. The results can be read through
the blinking pattern of the A/T CHECK indicator or the malfunction indicator lamp (MIL). Refer to the table on
AT-84, "
CONSULT-III Function (TRANSMISSION)" for the indicator used to display each self-diagnostic
result.
 The self-diagnostic results indicated by the MIL ar e automatically stored in both the ECM and TCM memo-
ries.
Always perform the procedure on AT-38, "
OBD-II Diagnostic Trouble Code (DTC)" to complete the
repair and avoid unnecessary blinking of the MIL.
For details of OBD-II, refer to EC-54
(for VQ35DE) or EC-632 (for VK45DE).
 Certain systems and components, especially those re lated to OBD, may use the new style slide-lock-
ing type harness connector. For descrip tion and how to disconnect, refer to PG-68
.

8. Check foreign materials in oil pan to help determine causes of malfunction. If the ATF is very dark, smells burned, or contains
foreign particles, the frictional material (clutches, band) may
need replacement. A tacky film that will not wipe clean indicates
varnish build up. Varnish can c ause valves, servo, and clutches
to stick and can inhibit pump pressure.
 If frictional material is detected, perform A/T fluid cooler
cleaning. Refer to AT-13, "
A/T Fluid Cooler Cleaning".
9. Support A/T assembly with a transmission jack. CAUTION:
When setting transmission jack, place wooden blocks to
