Service Notice or Precautions
NCS000TK
A/T FLUID 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 radiator or replace the radiator. Flush cooler lines using
cleaning solvent and compressed air after repair. For A/T fluid cooler cleaning procedure, refer to
. For radiator replacement, refer to
OBD-II SELF-DIAGNOSIS
●
A/T self-diagnosis is performed by the TCM in combination 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-87, "SELF-DIAGNOSTIC RESULT MODE"
for the indicator used to display each self-diagnostic
result.
●
The self-diagnostic results indicated by the MIL are automatically stored in both the ECM and TCM mem-
ories.
Always perform the procedure on
to complete the repair and avoid
unnecessary blinking of the MIL.
For details of OBD-II, refer to
EC-47, "ON BOARD DIAGNOSTIC (OBD) SYSTEM"
.
●
Certain systems and components, especially those related to OBD, may use the new style slide-
locking type harness connector. For description and how to disconnect, refer to
.

amount of new ATF to use should be 30 to 50% increase of
the stipulated amount.
CAUTION:
●
Use only Genuine NISSAN Matic J ATF. Do not mix with other ATF.
●
Using ATF other than Genuine NISSAN Matic J ATF will cause deterioration in driveability and A/
T durability, and may damage the A/T, which is not covered by the warranty.
●
When filling ATF, take care not to scatter heat generating parts such as exhaust.
●
Do not reuse drain plug gasket.
5.
Run engine at idle speed for 5 minutes.
