    PLEASE HELP! No TCM Option Vehicle Read

    I have a 2007 Wrangler that i'm trying to tune. I go to read out the ECM and TCM but there is only an option for ECM. I do a full read and only get ECU data. Tuning the transmission is not possible because the data is missing.

    What could be the problem? Is my TCM locked?

    Thanks!
