Engine Light On - Need help with codes
Hello I need your help!
My 2015 C7 engine light was on, so took it to Chevy and they stated the codes were P0700 and P0711.
They said they found nothing that needed to be repaired
they reset the codes and I took her home.
Now it is back on again.
It will be on one day, and then off a few days later, but then it comes on again.
Any thoughts??
much appreciated! Dr OBrien

If you google those codes here is what it says:
To answer the question, the P0700 is a generic fault indicating that there is a malfunction with the transmission circuit, which is the P0711, indicating that there is an issue on the transmission fluid temperature circuit, which involves : Transmission Temperature Sensor.May 22, 2023
There is a known problem with some of the transmission wiring harnesses, in particular, the trans fluid temperature sensor wiring.
My guess would be that your car is experiencing this problem.
There is lots of information about this on this forum. You can try searching for the code numbers or "transmission temperature sensor" and you will probably find a lot of information, including how to replace that wiring harness.

I have a 2017 stingray 8 speed auto (31000 miles) and mine threw those codes about a month ago. The only difference is mine went into limp mode. I had mine towed to the dealer and they had to replace the transmission wire harnesses and a sensor. It cost me a little over $1400 dollars. They also replace the transmission fluid along with the filter. You can DIY for about $300. There is a video on u-tube on how to do it yourself. Good Luck

Take the car to the dealer, or a reputable shop that has experience with Vettes, and have them fix the problem.

Did you have the same problem and did you notice any difference in the shifting of the transmission. Only drove mine a couple of times and it shifting was smoother than before.
