2015 8L90 Trans Fluid Temp Sensor & Harness

[SizzlingSkilletz]

I am looking to replace my sensor and the harness as they are known to be bad and causing the p0711 code. In my research I found the 2015 has a split harness but they changed it in 2016 to a one piece harness and then I believe they went back to the split one, not sure which year. 

 

What is the part number for the sensor and harness? I've looked everywhere and can't find nothing, plenty of threads but noone has mentioned part numbers and acdelco website does not have a part listed in their catalog for that year.. nor does any parts site like napa or autozone

I believe all of the part numbers are outlined in the special service bulletin in this article. 18-NA-355. Its been revised a couple times, just make sure ya get the most recent recommendation of the mobile 1 fluid. The water retention of the old fluid was a key problem. I'd check, the dealership may do it for free. Good luck!  I'm getting mine done on Thursday.
