Disabling DTCS

first time using tunerpro to edit a bin, and i'm looking to disable the DTC's for rear o2s egr etc etc, when i look at the tooltip it shows 0,1,2,3 for values, but i've got everything from 0-255 in the actual cells, and some dtc cells are missing entirely. any advice would be helpful, using the version 5 xdf for 12202088 and OS 12212156 if that helps at all.

also looking for info on how to change the transmision type, as the tooltip for it says ***this parameter shouldnot be changed*** and i need to change from a 4l60e to a manual

well nvm i'm an idiot. the 12202088 xdf doesn't fully define the 1221256 os calibration. now to figure out how to change to a manual trans
