    Default Transmission Swap Issue P0845- Nissan Altima

    Swapped a 07 Nissan transmission from 2009 and now get a P0845 code when I start the car. If I clear the code it stays cleared until i restart the car. Car runs/drives fine. I read that I need to reprogram the ECU and TCM? Is this true? What is the cheapest way of doing this? I found a Consult 3 for $350, but I don't know if it can do anything without the security cards. Any help is appreciated thank you.

    Code didnt exist before the swap. It is a compatibility issue which requires reprogramming the TCM. Question is if I can do it myself cheaper than the dealer.
