I have a 2009 G8. Just did a bunch of things on the trans side of things. I went to flash the tune and it said failed on the TCM side. Thought that was weird. So I went to do the reset/preset in the scanner. I clicked the buttons but nothing happened. The little status bar at the bottom didn't move. Not sure what my next step is here to get this thing loaded up but any help would be appreciated. Thanks
I disconnected the battery and tried again. Between modules it does the 15 second wait. Before that loading bar is done it says failed. Data Integrity Check Failed. Thanks in advance.
not sure on the battery disconnect..but when I had my g8 gt...I had to pull the tcm fuse for about a minute, before it would flash the tcm.

I'll try that. I also sent an email to support. But if any one else has run into this, help with a solution. Thanks.
