Tranny problems 4th gen

[Steviesunshine]

Hey all first post. I’ve had my 2017 ram 1500 sport since brand new. I’m at about 110000 miles and noticed that my mpg is getting horrible. I put the computer on the car and came up with a ****ton of codes with no cel showing. It’s the 8 speed tranny. I was wondering if anyone had something similar? And if so what was the outcome. I personally think it’s the tcm but I could be wrong

Remove the harness that attaches to the TCU and inspect for corrosion
or heat related indications..Is the case grounded, does it pick up ground
from case or internal ground?? This is some place to start!! RAMaway.

Definitively buy some of this and use it: https://www.amazon.com/CRC-05103-Electronic-Cleaner-11 just like the previous poster suggested.
