snow/ice, etc.), or while driving/sitting in traffic at slow speeds or idle:

The red A/T Oil Temp lamp began
flashing,
A/T
OIL TEMP
And/or

Vehicle would not move (the engine felt
like it had no power),
And

Vehicle operation returned to normal
when the engine/transmission was
allowed to cool.
ACTION
1. Compare the vehicle’s current TCM part number to the part number listed in Table A on
page 7.
2. If the current TCM part number matches a part number listed in Table A, follow the
instructions in Table A.
IMPORTANT: The purpose of ACTION (above) is to give you a quick idea of the work you
will be performing. You MUST closely follow the entire SERVICE PROCEDURE as it
contains information that is essential to successfully completing this repair.
Nissan Bulletins are intended for use by qualified technicians, not 'do-it-yourselfers'. Qualified technicians are
properly trained individuals who have the equipment, tools, safety instruction, and know-how to do a job
properly and safely. NOTE: If you believe that a described condition may apply to a particular vehicle, DO
NOT assume that it does. See your Nissan dealer to determine if this applies to your vehicle.

SERVICE PROCEDURE
IMPORTANT: Before starting, make sure:
 ASIST on the CONSULT PC has been synchronized (updated) to the current date.
 All C-III plus software updates (if any) have been installed.
 The CONSULT PC is connected to the internet (Wi-Fi, or cable).
 No DTCs are stored.
TCM Reprogramming
1. Connect the plus Vehicle Interface (plus VI) to the vehicle.
CAUTION: Make sure the plus VI is securly connected. If the plus VI connection is
loose during reprogramming, the process will be interrupted and the TCM may be
damaged.
2. Connect the AC Adapter to the CONSULT PC.
CAUTION: Be sure to connect the AC Adapter. If the CONSULT PC battery
voltage drops during reprogramming, the process will be interrupted and the TCM
may be damaged.
3. Connect the GR8, set to “Power Supply” mode, to the vehicle battery.
CAUTION: Be sure the GR8 is connected securely to the battery. Make sure the
battery voltage stays between 12.0V and 15.5V during reprogramming. If the
battery voltage goes out of this range during reprogramming, the TCM may be
damaged.
4. Turn OFF all external Bluetooth® devices (e.g., cell phones, printers, etc.) within range
of the CONSULT PC and the VI.
CAUTION: Make sure to turn OFF all external Bluetooth® devices. If Bluetooth®
signal waves are within range of the CONSULT PC and the VI during
reprogramming, reprogramming may be interrupted and the TCM may be
damaged.
5. Turn the ignition ON with the engine OFF.

The engine must not start or run during the reprogramming procedure.
6. Turn OFF all vehicle electrical loads such as exterior lights, interior lights, HVAC,
blower, rear defogger, audio, NAVI, seat heater, steering wheel heater, etc.
IMPORTANT: Make sure to turn OFF all vehicle electrical loads. Make sure the
battery voltage stays between 12.0V and 15.5V during reprogramming. If the battery
voltage goes out of this range during reprogramming, the TCM may be damaged.
7. Turn ON the CONSULT PC.

Shift position: D

Transmission fluid temperature: 75°C (167°F) – 90°C (194°F)

Output speed: 0 RPM

Engine speed (control): 600 tr/min (RPM) or more

Brake switch (control): ON
14. When the above conditions are met, select Start.

Current status will change from Waiting to EXECUTING.
NOTE: If current status indicates EXECUTING, wait (about 3 minutes) for the first
adjustment procedure to complete.

Second Adjustment Procedure
16. Confirm the following conditions (refer to the C-III plus screen):

Shift position: D

Transmission fluid temperature: 75°C (167°F) – 90°C (194°F)

Output speed: 0 RPM

Engine speed (control): 1,250 – 1,750 tr/min (RPM)

Brake switch (control): ON
17. When the above conditions are met:

Current status will change from Waiting to EXECUTING.

Keep the RPM about 1,500 so that when the RPM drops, caused by transmission
shifts, it will not interrupt the procedure.

If the procedure is interrupted, follow the on screen instructions (which includes
turning the ignition OFF and back ON), and then start from the beginning (step 13).
NOTE: Keeping the rpm in the correct range is a bit challenging, and may take a few
tries (practice) to get it right.
18. Wait for the second adjustment procedure to complete.

When complete, current status will change to Waiting.


Brake switch (control): ON
23. When the above conditions are met:

Current status will change from Waiting to EXECUTING.

Keep the RPM about 1,500 so that when the RPM drops, caused by transmission
shifts, it will not interrupt the procedure.

If the procedure is interrupted, follow the on screen instructions and start from the
beginning (step 13).
24. Wait for the fourth adjustment procedure to complete.

When complete the screen in Figure 30 (next page) will display.

IMPORTANT INFORMATION FOR THE CUSTOMER

Completing the transmission adjustment procedure has erased ALL of the TCM
“adaptive learning values” that have accumulated over time. The transmission will
shift differently than it did before this procedure was performed (especially for
vehicles that have been driven over 1,000 miles).

The Aisin 6-speed A/T has the ability to enter into a learning mode once the vehicle
meets the following criteria:
 Make sure there are no warnings in the Meter pertaining to reduced power mode
such as low fuel or low DEF.
 Confirm the vehicle is not in Tow Mode. If in Tow Mode, the vehicle will be
prevented from entering into the learn mode.

Learning takes place with upshifts at steady accelerator positions from 1st gear
through 5th gear continuously and repeatedly once the above criteria have been
met. Improvements occur during repeated upshifts.
