I have an 06 magnum R/T. When I crank it up cold and put it in drive or reverse I get bad mechanical noise. Park and neutral quiet again. The noise only last a few seconds when in gear and wont happen again until it sets a few hours. If I let it warm up a few minutes before selecting a gear, no nasty noise. On the road it shifts smooth. What's up with my Nag1 ?

 

Hard to tell. Ned to identify where the noise is coming from.
