Thanks

Ok thanks. Do you know the communication logic on these platforms? If so any chance you could explain, or provide a sketch of how each module sends and receives to each other?

Here are the codes from my innova sd29. At first they dont seem related but im thinking that if the bcm sends a corupt packet or signal to the tcm or not at all because the ebcm signal was not read properly that tcm might not lock because it doesnt know the wheel speed or brake position preventing the lockup

Hello all first post ever. 2016 sierra 2500hd CC,LB,work truck. Both codes flagged on same drive cycle. Before I drop the trans pan, im going to rule out canbus. I feel that this comms error could prevent tcc lock up. Has anyone seen this before as I can't find any source that says this can happen but when I break it down to first principles, I can find a correlation. Any input or thoughts would be helpful. Thanks y'all. PS im canadian and love my neighbours to south. I also notice a lot of questions about trans temp and want to say if something doesn't make sense about operating temp try changing units on your display!!!
