I have checked into powertrain warranty transferability for a 2005 SRT6 and two 2004 coupes. Only one of the 2004's was transferable, even though all have owners manuals that say they are. It was explained to me that it depends on what was being offered when the car was originally sold. I have found the best way to find out is to use the Chrysler web site and send in a written request which includes the VIN. I received prompt replies IN WRITING which is a big advantage when you just have 30 days after you buy the car to be sure you can transfer it and then need to get to a dealer to do it.
