I have a rebuilt transmission that is using a donor TCM from a 2019 Dodge Charger SRT Hellcat (LD, 05035608AC). When we placed the new transmission in the car it started no problem. When I went to inspect the calibration and OS it would not let me write my existing TCMs calibration or OS into it, 68239153AG, with the WiTech. Does anyone have a technique or know where in the WiTech menu's we can for a TCM overwrite? Is this even possible or am I screwed?
Any help is appreciated.
