I got my RT Magnum a year ago. My friend and associate who is quite the gearhead was impressed enough to buy himself a hemi Charger. One thing I would change on my car, if I could, I would have a manual transmission. Even living in the city I prefer the control. So I was complaining to my boy about the trans being half a self-shift;it will hold in a gear and not upshift but will always downshift under any load. He tells me his Charger will stay in any gear even floored, like a manual. I didn't truly believe till we went for a ride. And so it was. We wondered: it it a computer chip? Can it be swapped on my '06 Magnum? It seems unlikely Chrysler would build mechanically different transmissions for the same drivetrain. He bought the Charger with a performance upgrade, 10 more hp and better trans, not available on the Magnum to my knowledge. So how about it? Can I make the mod? This is the place to find out for sure. Thanks.
