IF YOU CONFIRM
Transmission shift shock when accelerating enough to create a 7th gear to 3rd gear down shift.

ACTION
1. Refer to step 6 in the SERVICE PROCEDURE to confirm TCM reprogramming applies.
2. If it applies, reprogram the TCM.

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.
Infiniti 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 Infiniti retailer to determine if this
applies to your vehicle.

SERVICE PROCEDURE

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 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.
