Whenever I'm decelerating from high rpms down into the 3500-2500 range in any gear the motor makes a grumbling noises. Only thing I can say to describe it is that it sounds like VERY loose sheet metal or fan grinding. In any case I don't like it AT ALL
McMark scared me when he says it's likely the trans warning me.
The car runs, shifts and behaves well. Doesn't overheat either
Where would you start... Besides hiring an Oompa Loompa to ride in the engine compartment with a stethoscope!
