I have only had my Dart for about a month, but as I turned the radio down to listen to the engine, I noticed the 6 speed automatic transmission downshifts very dramatically. It is very clunky with a loud throw out sound. Is this the natural sound of the tranny or is it an issue? There are no "drivability" problems, but shifts very loud "especially in traffic". I have about 3000 miles left on the Manufacturers warranty. So far I've noticed it is the loudest downshifting from 2nd to 1st.
