P0700 code BUT!

[Jerrouss]

Hello gang,
My wife just came home from work with an engine light & I got a P0700 code, not even a year since being serviced Dec 10 last year with a full fluid flush & filter. She said that it’s driving & shifting fine. I’ll go to the transmission shop tomorrow. Any thoughts to any techs here? Thank you in advance,

Did you check fluid condition and level?

Keep us posted. A good scan tool may let you see the failure records, a recording of what was going on when the code set. Check your battery and its connections.

I went to the transmission shop today and it’s the wire harness and they want $600. And I called the local gmc dealership and there’s a special campaign for it. Free repair
