we tried to recode the tcm with the limited codes but the 6 would not acept it,, we did put a tcm into a 6 from a charger srt8, the car started but would not go into gear, I have a spare tcm for my 6 if a limited wants to try it in a limited. i think we have to install the transmission, tcm, and rear diff from a limited and hope that would work. jim
