APPLIED VEHICLES:

2016-2017 Titan XD (A61)

APPLIED TRANSMISSION:

6AT: RE6R01A

APPLIED ENGINE:

Cummins 5.0L V8 Diesel

SERVICE INFORMATION
Anytime the 6AT (RE6R01A) transmission or its Transmission Control Module (TCM) is
replaced, an adjustment procedure must be performed using CONSULT-III plus.
IMPORTANT:
If the transmission adjustment is not performed, the transmission may exhibit any of the
following conditions:


Poor shift quality



Improper shift timing



Engine RPM flares between shifts

IMPORTANT: Do Not perform the transmission adjustment procedure on vehicles with
more than 500 miles on the odometer, unless the transmission or the Transmission Control
Module (TCM) is replaced.

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

1. Make sure the transmission is warm.


It may be helpful to take the vehicle for a drive (approximately 10 minutes) to warm
the transmission.

2. Confirm the transmission fluid level is correct.


Follow the procedure for Checking the AT Fluid Level in the Electronic Service
Manual (ESM), section TM-Transaxle & Transmission.

3. Set the parking brake.

4. Chock the wheels.

5. Connect the CONSULT PC to the vehicle with the plus VI.

6. Start the engine.

7. Turn the A/C system OFF.

8. Start CONSULT-III plus (C-III plus).

NOTE:


While performing the Transmission Adjustment procedure, a screen like the one in
Figure 3 will display.



Review the call outs in Figure 3 explaining the information on this screen.



This information will be helpful as you perform the Transmission Adjustment
procedure.



While C-III plus is performing automatic adjustments, you will hear and feel the
transmission changing gear position.

Instructions for current step or
action.
If the procedure stops or is
interrupted, the action needed
to continue the procedure will
be written here.

Scroll to see all
instructions for
current step or
action.

Waiting indicates input or action
from you is needed.
Executing indicates C-III plus is
performing actions.
Other items indicating status
such as engine speed not
ready, or brake switch not ready
may be displayed here.

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.

Step 14

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.

Third Adjustment Procedure
19. Confirm the following conditions (refer to the C-III plus screen):


Shift position: R



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

20. When the above conditions are met:


Current status will change from Waiting to EXECUTING.

21. Wait for the third adjustment procedure to complete.


When complete, current status will change to Waiting.

Fourth Adjustment Procedure
22. Confirm the following conditions (refer to the C-III plus screen):


Shift position: R



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

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 8 (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.
