Great news, car moves under it's own power, gears 1-4 move no problem while driving after we got it back together at the shop. Long story short, Dodge sent us the wrong cooler so I have to wait a few more days to ensure I can drive it fully. Little chunky but the car is learning its shift points, 3k stall also doesn't help as well when trying to get going for now.
Right now other than waiting on the right parts is the TCM mismatch. The TCM came from a friend who had it in his HP90 but moved onto a TH400, when trying to write my tune file to the TCM I get an OS mismatch error. We tried to recode the TCM with the Witech but it won't allow us to flash it as it is coded to a LD platform car (charger), LA is Challenger. Does anyone know of any way with a witech, hptuners or another tool to flash the TCM to my year/firmware version? TCM's for years 2015-2022 are all the same so that's good new, just that we can't overwrite the OS/code.
Any help would be appreciated. I'd like to drive this thing maybe once ... 🤣
