I decided I wanted to update the firmware on the TCM in my '18 Raptor to try and iron out some weird shit that the 10R80 transmission does. I had an OBDLink-EX adapter that I had used many times on my truck, but when I attempted to update the firmware on the TCM it faulted halfway through killing the update. Once I realized the adapter was shit, I figured I would try an ELM-327 I have to use Melcodiag on my Ducati. Adapter was slower, but ran all functions normally except when I tried to update the firmware on the TCM with it. The data packets are too large and the adapter faulted. This put me in a pickle because my truck was dead, so I tried different settings/configurations to try and get a successful update, including a profile delete. Once the profile was deleted I couldn't talk to the TCM at all. Thought I was screwed and would have to get a new one from Ford, since everywhere I read stated as such. Emailed Forscan and they were able to rebuild my original profile from the logs, which I loaded and used to communicate and update the firmware on the TCM using a NEW OBDLink-Ex adapter I got from Amazon. Also updated the BCM and PCM with no issues. Truck was down a couple days, but the fellas at Forscan F'ing kick ass! Couldn't thank them enough for a fix.
