    TCM location 2018 Colorado

    Im looking for the location of the TCm on my 2018 Chevy Colroado V6 A8. I originally thought it was the module behind the coolant reservoir on teh passenger side of the firewall. But thats the ecu so Im told.

    I need to send the TCM in to get unlocked so the tuner can finish the tune but cant figure out where it is. Can anyone help?

    So the TCM is next to the ecu? Ok. I’ll give it a look see over there!

    It looks like there is a module to the left of the ecu.
    I?m hoping that is a cover because the TCM pics I have found look different.

    Anyways, this afternoon I?m going to try to remove it and see if it?s the correct one. And if it is send it to hp For unlock.

    I tried to post a photo but got the jpeg error.
