Is there ability to "Write Entire" as an option for TCMs? Can this feature be enabled? The issue I have is the last two FG falcons I that I tried returning the TCM back to factory tune have both given me issues. Gears wont shift correctly and when they do they slip and slam into gear and eventually a transmission error will appear on the cluster. If I put the modified auto tune back in the cars and they are fine again.
Please note these are 2 separate cars which I tuned from standard having similar issues when attempting to write factory calibration. Seems that returning calibration back to stock on TCMs is causing issues. Has anyone else experienced any similar issues?
