2013 - 2014 ALTIMA V6 SEDAN AND PATHFINDER;
JUDDER DURING LIGHT ACCELERATION
APPLIED VEHICLES, VINS AND 2013 - 2014 Altima Sedan (L33) with V-6 engine only
2013 - 2014 Pathfinder (R52)
DATES:
CVT
APPLIED TRANSMISSION:
IF YOU CONFIRM
When driving an Applied Vehicle a judder (shudder, single or multiple bumps or vibrations)
happens during light acceleration,
and all of the following when the issue occurs:
• Vehicle speed is between 5 and 35 mph.
• Throttle position is about 10%.
• When issue occurs, if more throttle is applied issue stops.
• No DTCs are stored.
ACTION
1. To determine the root cause perform the Service Procedure starting on page 3.
2. Should reprogramming the TCM NOT resolve the concern, first verifying the vehicle’s
service history and then recording and analyzing the data with Consult III plus (C-III plus)
as the symptom occurs is required to accurately determine the root cause of the incident, if
it should occur.
NOTE: This bulletin does not apply to a condition called “fuel economy drone”. If the
customer describes their issue as a lugging or as a groan/drone at low speed this is a
normal condition to maximize fuel economy. Some customers will describe the condition
as similar to a manual transmission vehicle in high gear at low speed.
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
TCM Reprogramming
NOTE:
•
Most instructions for reprogramming with CONSULT-III plus (C-III plus) are displayed
on the CONSULT PC screen.
•
If you are not familiar with the reprogramming procedure, click here. This will link you
to the "CONSULT- III plus (C-III plus) Reprogramming" general procedure.
CAUTION:
•
Connect a battery charger to the vehicle battery.
If the vehicle battery voltage drops below 12.0V or rises 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 VI. If Bluetooth® signal waves are within
range of the CONSULT PC during reprogramming, reprogramming may be
interrupted and the TCM may be damaged.

7. Follow the on-screen instructions to navigate C-III plus and reprogram the TCM.
NOTE:
•
In some cases, more than one new P/N for reprogramming is available.
¾ In this case, the screen in Figure 3 displays.
¾ Select and use the reprogramming option that does not have the message
“Caution! Use ONLY with NTBXX-XXX”.
•
If you get this screen and it is blank (no reprogramming listed), it means there is no
reprogramming available for this vehicle. Close C-III plus and refer back to ASIST for
further diagnosis.
IMPORTANT: If C-III plus locks up or freezes at this point or displays “cannot
complete reprogramming, the CONSULT PC is set up with User Rights.
Reprogramming can be completed with Administrator log in”, the TOUGHBOOK
settings need to be changed so that Users have full access rights. See your
Dealership’s IT System Administrator for details.

duplicated.
•
Once duplicated, immediately record the data with the C-III plus that was set up in
steps 1-7 as the issue occurs.
Save and Review Recorded Data
9. After the C-III plus data has been recorded with DATA MONITOR, save the data file as
“FlyingGraph(last 8 of VIN).txt file” (example: FlyingGraphEM123456.txt file) onto the
Consult PC desktop as shown in Figure 11.
NOTE: The Flying Graph software is available on the desktop of your Consult PC. It can
be used for the data review.
•
Data files must be saved as “.txt file” type before it can be used with the Flying Graph
application. Refer to Figure 11 below for example.
•
For an illustration of the C-III plus desktop shortcut to the Flying Graph application see
Figure 12 on the next page.
Select Save first and
then name the file
Save the recorded data as a “.txt file” onto the

are a normal response
to vehicle input.
Figure 14
NOTE: Figure 14 shows INPUT REV, SEC SPEED, ENG SPEED, PRI PRESSURE and
SEC PRESSURE from a vehicle that does not have a judder present.
13. During data review, if your data shows a Repetitive Pressure Vibration in either
PRI PRESSURE or SEC PRESSURE, and also shows an irregular (non-smooth) line in
one or more speed signals (ENG SPEED, INPUT REV, SEC SPEED) as indicated in
Figure 13, replace the CVT to resolve (Figure 13 shows Repetitive Pressure Vibrations
circled in red).
•
Do not replace the torque converter assembly if the data review shows Repetitive
Pressure Vibration as described above.
•
If a judder is present and the recorded data review shows that the data lines
are smooth with no oscillations as shown in Figure 14 above refer to Torque Converter
Replacement on page 17.
NOTE: Refer to the appropriate section of the Electronic Service Manual (ESM) for the
procedure to replace the CVT, as needed.
• If a judder is present, recorded data review does not indicate pressure vibration and
the torque converter in the CVT is already “D” level or greater (see FLOW CHART B
on page 17), refer to ASIST or the appropriate section of the ESM for further diagnostic
assistance.

1. Replace the torque converter with the new one listed in the Parts Information:
• Refer to the TM section of the appropriate Service Manual for replacement information.
NOTE:
• Make sure the converter housing oil seal (front seal) is not damaged. If damaged,
replace it.
• If the front seal is replaced, use special tool J-50817 (oil pump seal installer) to install
and properly seat the seal.
• Make sure CVT fluid, as a lubricant, is applied to the front seal, torque converter snout,
and input shaft o-ring seal before installation of the new torque converter.
