IF YOU CONFIRM
Any of the following issues:

When cold (transmission fluid below 140°F [60°C]), there is an engine RPM rise
(200 to 500 rpm flare) during the 1-2 shift, 2-3 shift, and/or the 3-4 shift.

While slowing to a stop, a 2-1 down shift bump is felt just before stopping.

Harsh up-shifts.

Shift shock when lifting foot from accelerator.

Gear hunting while driving in city traffic.
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
Reprogram the TCM
NOTE:

Most instructions for reprogramming with CONSULT-III plus (C-III plus) are
displayed on the CONSULT PC screen.

For the Titan XD Diesel, the GR8 set to ECM power supply mode can be attached to
either 12 volt battery.
CAUTION:

Connect the GR8 to the 12V battery and set to ECM power supply mode.
If the vehicle battery voltage goes below 12.0V or above 15.5V during
reprogramming, the TCM may be damaged.

Be sure to turn OFF all vehicle electrical loads.
If a vehicle electrical load remains ON, the TCM may be damaged.

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.

Turn OFF all external Bluetooth® devices (e.g., cell phones, printers, etc.) within
range of the CONSULT PC and the plus VI. If Bluetooth® signal waves are
within range of the CONSULT PC during reprogramming, reprogramming may
be interrupted and the TCM may be damaged.

NOTE: There are 4 adjustment procedures within the Transmission Adjustment.
First Adjustment Procedure
13. 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): 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.
15. Wait for the first adjustment procedure to complete (about 3 minutes).

When complete, current status will change to Waiting.

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.


Output speed: 0 rpm

Engine speed (control): 1,250 – 1,750 tr/min (rpm)

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 8B (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:
 The vehicle will need to be driven above 55 mph for a minimum of 5 miles to
bring the exhaust and after treatment systems up to normal operating
temperatures.
 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.
