Maybe someone out there is more aware of the new computer system than I am, but my sense is they are VERY complex these days. I was told the systems even learn your driving habits and adjust gear shifts to maximize engine efficiency given them. I could easily see such a complex system being specifically programmed to work only with an engine/tranny/gear ratio set up (i.e different computer modules needed for hemi/8 speeds with 3.92 and 3.21 gearing). This is something I would hope dodge and your ram dealer service would know about however--if that's the case, the swap should have gone hand in hand with a swap to a different computer system.
