My 2016 Sierra doing it now. 200k but runs great. Trans shop quoted me 6k to replace the trans. 85* day at startup my trans temp gauge reading 43*. Drove to the store got up to 153, Then dropped to 63 when I backed In. Temps all over the place.

Yeah if it has this code and is doing that I would expect the same thing to be the issue. Not a complete transmission replacement.

What truck do you have? I'm having this issue on my colorado and need to replace the sensor. Alteady changed fluid thinking that's what it needed. P0711 returned. Going to replace the sensor hoping that will fix it

I have a 2017 Silverado. I would assume if you are having similar issues this could be it, but not 100% sure. Thanks!

Great video! I have a 2017 gmc sierra and have the same two codes p0700 and p0711. I want to assume since its the same year and same 8 speed transmission, then it probably has the two piece wiring harness. How did you know which harness to replace? Thanks.
@wrenchingcouple20349 ай бұрын
The code for me was pointing to the transmission temp sensor. I did a little digging into a wiring schematic and confirmed with the local dealership as to which harness had the physical temp sensor attached to it. Luckily the one that has it is the easier to replace harness. Hope this helps!

Other than the CEL code, is there damage caused driving without changing the harness? I mean, is temp really fluctuating or just a bad harness reading as the problem?
@wrenchingcouple20342 жыл бұрын
In my opinion and I am no expert, I would say that the temp isnt fluctuating and it's just the reading back to the truck. I drove it for awhile while I diagnosed it and waited for parts and didnt see any trace of physical damage when I opened the transmission. My only concern is what affect the temp has on shift points. Maybe the temp read back has 0 affect on shiftingor anything transmission related other than being a warning. . That is something I didn't know so I just choose to fix the problem.
