I have a 2006 Ram 5.7 4X4 which had the NGC3 pcm, but I swapped a 2007 Ram 5.7 4X4 (NGC4) into my truck. If I?m in Park and shift to drive and take off everything is fine, but if I come to a stop afterwords it tried to take off in 2nd gear. It drove 100% fine with the NGC3. Can someone possibly tell me what to look into.
