Hope you're under warranty...check to be sure. I can't remember if it was in 2005, but for a few years around then (I really think it was 2005), Dodge had a transferrable 7yr/70,000 miles Powertrain warranty, which would apply, even if you bought it used. This would cover the engine and the transmission. Check your miles and refer to the Dealer service department for verification on your particular model.
