I know it's been awhile since this thread, but I am having a similar problem that just seemed to have gotten a little worse. Enough to where I need to do something about it before I tear something up. I feel a loud vibration almost like pure bass coming from the truck when I stop in gear. It goes away when I accelerate and put in park. I am wondering if this is transmission mount related or more of a motor mount issue. Any advice or comments would be appreciated. I'm going to at least take a look this weekend and be sure everything is tight. Thanks in advance for any tips/advice! Shane
