    The past couple of storm I've spent a lot of time in the truck and have become very familiar with all sounds.

    However last storm I've been hearing a new sound that I don't think is normal but maybe I'm wrong. In the cummins, when going from Reverse to Drive I always put in Neutral to let off any pressure and come to complete stop before shifting. Once shifted into drive I hear a suction noise, is that normal or is there some sort of a vacuum leak?

    06 cummins, automatic, what number tranny is it?
