The first time was around 250f once I poked around and found out tranny temp was not being displayed and I turned it back on

Tomorrow hopefully the tranny guy is going to drop the pan, my best guess the torque converter is on its way out? Just really confused because the truck drives fine until just before it shuts down, no freewheel it immediately down shifts also showing a code that loat communication with tmc which I would guess happened when the truck shut down

Yes celsius I'm lead to belive that the bypass failed to open? Not sure what temp the stock one is supposed to. I have only had this issue twice,the first time I was able to roll into a parking lot, dash said idle engine trans hot at this point I knew nothing of the bypass after looking for leaks and a few mins later I shut the truck off and restarted all of a sudden the fans went into hyper drive and the temp came down . Second time similar but without warning on dash fan failed to come on had to let it cool before I was able to move truck again luckily this time I was able to roll In to my own driveway

Hello all seem to be spinning my wheels at the moment. 2018 z71 shutting down not limp mode, when transmission reaches 150 degrees has any one ever had this happen? Wondering if I should do the bypass delete is it suitable for canadian climate any input would be appreciated tia
