Rattle noise!

I was driving to work this morning and all of the sudden I had a rattling noise coming from what sounds like the transmission. It only happens while driving. I hear nothing when at a stop or if I put my foot on the brake and let the clutch out thought if it had anything to do with the clutch I would hear it then but heard nothing. Any help would be great thanks.

Get it up on jack stands and find exactly where the sound is coming from, then maybe we can help you solve it. Trying based on a guess will just get more guesses.

Checked it out this afternoon the sound is defenatly coming from the trans. Sounds like there is a marble in the trans and the faster the truck goes so does the marble. I drained and replaced the fluid didnt see anything.

Auto or manual?

It's a manual trans.
