The TCM part number determines whether the vehicle needs to be programmed when replacing a transmission or valve body. To check your TCM part number, use a level-3 scan tool to look up ECU Information and under Transmission. The TCM part number should start with 31036-XXXXX and the 5 characters following the hyphen indicate the programming on the TCM.
The images below show how to do this on a CONSULT III +, which is Nissan’s dealer-level programming software.
Once you have your TCM part number, check to see whether there is a programming update on Nissan TechInfo
- Go to https://www.nissan-techinfo.com/ecm07.aspx and enter 30136 in the first ECU part number search box
- Enter the next 5 characters of the ECU part number and click on the Nissan dropdown in ALL CAPS
- Compare the ECU ID to see if there is an update. If you have the current version of ECU software Nissan will not offer a configuration.
- In order to update the ECU file, you need a subscription to Nissan’s programming software (NERS or Consult III Plus). If you have this software you can download the calibration file from Nissan for $30 and reflash the TCM.
- If you do not have the software and cannot hire a programmer with the software, Nissan dealerships will perform the reflash for between $100 – $300.
- The DrewTech RAP Kit is also capable of reflashing the TCM on all Nissan models except for the CVT8 that comes with a programming CD (JF016E / RE0F10D in the 2013 and newer Altima and 2014 and newer Rogue)
