For some reason I cannot connect to the tcm. I am getting a message that I need to upgrade to a commercial v2. I have already downloaded and recalibrated the trans in the past without issues. the license shows for the pcm and tcm of my vehicle. It has been awhile, maybe I am doing something wrong

nevermind I reregistered my efi and it worked. Strange I had to do that, but oh well. Thanks
