Do my troubles ever end? Now I got a terrible noise comming from underneath my truck. Sounds like metal rattling against metal, and it's quit loud. Seems in time with the RPM's, and will not happen in park or neutral. It's gotta be my tranny (700R4, rebuilt once), but is there anything else it might be? What might it be in the tranny? This really pisses me off, since I don't have the money or the time to deal with it right now.
