    2005 Ram pcm upgrade to later unit for trans tuning?

    Im aware this has probably been gone over but i was unable to find the information i need. Im ready to purchase an pcm but the truck Ive been tuning on is an 05 with a 4.7, still cable type throttle. If I purchase a 2007 pcm for a Ram 4.7 will this give me the correct calibration level to make proper adjustments to my 545Rfe. Thanks -Caleb

    Yes, but the Dash and some other sensors need to be dealt with,
