<div class='quotetop'>QUOTE(RedHeartbeat @ Feb 17 2006, 12:33 AM) [snapback]44678[/snapback]</div>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.Try unbolting the convertor and shoving it out of the way, then start it up to isolate the transmission totally and see if it still makes the noise. Also, are you 100% sure you don't have a bent pushrod in the valve train? That's what is sounds like to me. Take all the lifter loose and pull the rods and see if any of them don't roll straight. I've heard that noise before and it wasn't pretty.

I'm almost positive the noise isn't in the tranny. New tranny. TC sent back to PI and they say its okay, new flexplate. The noise was there before all of these parts were swapped.
I am not 100% certian that I do not have a bent pushrod. I am certian that I do not have a bent pushrod in the area the noise is coming from. chromemoly units. Tough SOB's and I inspected the passenger side.
I am 6.0 shopping today. Found a 04, LQ4, 9K miles for $1500.
What wasn't pretty about this noise you've heard before? I am thinking rod bearing. Engine only has 45K miles. Oil change frequently with Mobile 1. Never over 6K rpm.
