    This controller did not autodetect the TCM when it drove in. It's been doing much of what you said it would be doing. :(

    This is a 2007 CLASSIC and TIS lists a bunch of controller options when I try to flash it. I lifted the controller to get the correct

    part number and it failed anyways....

    I'll keep you posted.

    Strange..... The truck starts for one half second and dies with the non responsive TCM in the truck....

    Got the TCM back online and updated and now the Truck runs fine.

    Never saw that before.

    This subject has come up in various threads for years, and has created headache after headache. I have a working T14 I will be happy to ship to you Ross. They have been available for 5 years, and been nothing but confusing.

    Wow, $400 a pop, that is crazy when you consider the price of some of the other controllers GM sell.
