    Default error $06ff TCM g8

    Hi all. Was flashing the TCM on our 09 g8 last night with the new auto cal and custom tune. The ECM took fine. But the TCM set the $06ff error at the end of the flash and has the TCM all messed up. Tried reloading the tune on the autocal. Tried pulling the negative cable. Talked to the tuner he resent the tune and did the same thing. Any help would be great. Thanks.

    I'm an idiot and put this in the wrong forum. Should be in the AutoCal.

    I'm not sure yet. My tuner said there was a glitch in the year of the last flash and that could cause the problem. Said it showed being reflashed October 2070. So he over laid a stock g8/TCM tune and sent it. I'll report back in a few hours. I hope it works. The car won't shift at all currently since it failed the flash.
