dodge just cameout with a new 6 speed transmission for their 2500 and 3500 series trucks,diesel only at this point,i have been looking for a different transmission for my 05 qc for awhile now ,reason being is we put alot of miles on this truck for work and the gas mileage is around 9-12,and i'd like to give the engine a decent overdrive unlike the one it has now,but i guess my main question is who could i get to reprogram the pcm for the new transmission,if its even possible
