    Default E38 Trans Tuning

    Well I played around with tune last night on my 2007 6.0L Avalanche and noticed there wasn't any transmission files. I think it's 4L70e. OS 12614088 is this not supported yet? I did down load the stock tune, quite a bit different from my 99 vette.

    Also, I'm not sure what pids to use, Scan tool acting crazy RPM,MPH,AFR commanded, TP%. Any ideas.

    Thanks
    Scott

    Well I wonder if there will be Trans Calibration if so when? Thats the most SOTP feeling from tuning stock (gas)cars and trucks.
    Have you made any changes to engine yet? The 6.0L is a little sluggish merging into traffic.

    If your vehicle has a 4L70E you need to read the TCM out as a separate file. Select T42 as the controller type, then read/program as normal, it won't take up another license if you have already licensed the ECM.
    EFILive always treats the TCM as a separate module, it's not combined with the ECM (there is a reason behind that, we aren't going mad).

    Cheers,

    Maybe about a month? I'm mapping the E67 now then it's the 6spd TCM.
