Default Klunking noise around the tranny

*UPDATE* 3/16/2010

Had a chance to work on it today. Went ahead and checked the u joints they look ok and show no play. But I found the driveshaft has alot of play in it. To make sure this wasnt normal I tried the same thing on my dads c1500 and its solid as a rock lol. Anyways here a quick video of the play and what seems to be the exact same noise in the video I took a couple days ago.





So I was at a McDonalds and I pulled up to the window and I hear a klunking noise ecoing off the wall. It stoped rite away when I stoped at the window. But when I pulled to the next window I just let it roll in drive and it did it again. All the way to the next window. It seems to only do it when I let the truck go by it's self or under a very lite load. It doesnt do it under medium or heavy load. And it sounds like its coming from the tranny. Its like a kluning metal on metal noise.

Ill try and get a video of the noise.

They need 3 windows for the times they make you pull up and wait 10min for your damn fries. Id call it we fell behind so you have to wait on your food while the people behind you get theres even though you ordered yours first window.
