    Flashing A50 TCM

    Hey y'all I've got a 2013 LML with a dead TCM and I am going to replace it but I was wondering if I am able to flash the A50 TCM with hptuners so I don't have to go to the dealer to get it done? I've never tuned a diesel before or anything with transmissions before so this is new to me.

    A new TCM or even a used one needs to be programmed by a GM tool to match your VIN/OS before you can do anything with it on HP Tuners.
    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.
