P0700 DTC

This DTC is just an informational DTC that gets stored in the PCM that tells you there are transmission codes in the transmission control module.

They set this DTC because a lot of code readers only talk to the PCM and it will miss the other codes that will actually point you to the issue.

So, we need to scan for codes again using a scan tool that can communicate with the other modules so that we can see what the issue is.

I am attaching the info below on this code and as you will see it basically just tells you to find the other DTCs and diagnose those.

Please run through this and let us know what you find. Thanks
