I unbolted the TC before I pulled the old tranny. The noise went away. Now thinking about this.... I unhooked the TC after the truck had sat about a week. When I started it up after the tranny install the noise was not there. While it was idling and I was filling up the tranny the noise slowly came back. After about 3-4 minutes of running.[/b]



Do you still have your stock TC. I would put that in and try it first, before I looked for another engine.
