    Default are all E92's created equal ?

    Have a new 2018 Yukon 5.3 Wanting to purchase a new ECM and TCM to tune and keep warranty with originals as un-programmed spares. Have GM TIS for VATS and latest factory downloads.
    Just see a lot of different part numbers for the E92. And with a 6spd have seen some use a T87 in place of the T87A Any issues tuning the T87A ? Trying to get rid of TCC slip
    Thanks !

    Part numbers must match, eg a 2016 E92 ECM will not work in a 2018 vehicle.
    EFILive does NOT support the T87A TCM.
    I no longer monitor the forum, please either post your question or create a support ticket.
