Since updating to the current beta, my trany is unrecognized. I'm not sure if this is a beta problem or a new TCM os. Attached is the text of the error and the saved tune.

Thanks

Did you recently have the Cold weather dealer update put in?
It's not an OS I have seen before, thanks for the file though, we can work on getting support for it.

Cheers,
Ross

Yes... My truck has seen -40F and I didn't want a fried trans from the high idle.

Thanks
