The TCM is integral with the control valve assembly, and built into the transaxle assembly.

This is not an appropriate repair for the average DIYer.

Are you sure the TCM requires replacement? If you replaced the transmission and did not properly complete the programming steps, then I would attempt to program the existing TCM, first.

Proper reprogramming will require one of the following:

1. Access to a CONSULT III Plus subscription (Nissan Publications) and a compatible vehicle interface, such as the J-47446-VI2-B, available from Bosch TechMate. The subscription price varies from $30 for 1 day to $1,250 for a year of access. The hardware interface retails for $2,215.72 through official channels, although can be found for less in the grey-market.
2. A suitable bi-directional aftermarket scan tool with Infiniti/Mercedes TCM replacement capability and J2534 vehicle interface. Common recommendations are the Snap-On Zeus or Verus, Bosch ADS, or Autel MaxiSys. I like the Bosch the best, but the Autel offerings are the most affordable.

Before replacing the TCM, Infiniti recommends using the CONSULT III Plus to perform the following functions:

• Save data for replacement TCM
• Save 'Operation log'

After replacement, Infiniti recommends using the CONSULT III Plus to perform the following functions:

• TCM programming
• Configuration
• ECU registration
• VIN registration
• Write call ID
• Oil level check
• Normalization and adaptation
• Write data for replacement TCM
• Clutch adaptation value writing procedure.

I just saw you posted the DTC in the thread title... Diagnostic info for P0513 does not indicate a problem with the TCM. P0513 is "Incorrect Immobilizer Key - Communication with the electronic ignition switch control unit has a mal-function." The service manual lists possible cause as the Electronic ignition switch control unit.

Are any other DTCs being thrown?

I remember you asked me to first Subscribe for Nissan Clll Plus Publications at a fee, either daily or otherwise.

Can you kindly help by providing a link to any of your recommended websites where l can Register and subscribe for the Access needed towards the resolution of my reprogrammng challenge

The subscription is region-specific, so I'm not sure the details in your region... But you can start the process, here:

Right off the bat, you're on an old version of CONSULT-III. Your screenshot shows v94.21, but the latest version is v95.12. Do you have a legit CONSULT-III? Or did you buy a grey-market clone? If it's legit and you have a valid subscription, you should update your software.

The "official" source is Nissan/Infiniti TechMate, operated by Bosch:

Tech-Mate Retailer Equipment Program

The CONSULT-III software license is ~$1,300. That's separate from the TechInfo subscription. If you bought legit hardware from someone other than TechMate (used from another shop, for example) you'd need to buy the software license, still.

I would not trust a grey-market CONSULT-III setup (software or hardware). If you don't want to use the genuine setup -- which is understandable, since it's ridiculously expensive -- then I'd rather use an aftermarket J2534 interface over a questionable clone/hacked setup. The Autel Maxisys is fairly affordable, for example.

To reprogram you need:

• The J-47446-VI2 vehicle interface (or compatible)
• A compatible computer (thankfully, starting with v91.10 you can use a non-Nissan-supplied computer)
• A current Consult-III subscription
• The paid VIN-specific ECU file for reprogramming
