    e38 manual to auto

    hey guys, to swap manual to 6l80e auto with a 2011 e38 ecm is it as simple as switching the option in the tune file?

    Its for a conversion so my only interest is the ecm and tcm talking to eachother.

    Not that simple.

    You need to have the computer flashed with a GM tool to a VIN/OS that uses the 6L80e. So basically a 2011 Silverado 5.3/6L80e could work for example or even a Camaro 6.2/6L80e file.
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.

    If you don't post your tune and logs when you have questions you aren't helping yourself.
