Hey all, first time poster here and it seems my problem is incredibly unique. I've been scouring for any info on someone who has had this issue but am not finding much. The car runs great, I just noticed it was not getting as good gas mileage as it should, (maxing out at maybe 29mpg highway driving conservatively) so I started to investigate.
As the title says, my 116k miles '15 LX Sedan is throwing a U0101 code: "Lost Communication With Transmission Control Module (TCM)" and there is no Check Engine Light active.
I have read that on other cars with traditional transmissions this would make the car be in "limp-home" mode and not shift, as well as reduce fuel economy. I haven't noticed any oddities in "shifting" but this is my first CVT.
CVT Fluid was changed at 102k, planning on doing that this week as well.
I also checked for any open recalls regarding the TCM, but there are none.
I've also heard that it could be a grounding issue somewhere along the way, but I'm not sure where to begin with that, either.
Any input would be appreciated. Thanks!
