Cant really here it very well. Is it rattling,ticking,knocking or what?

Sounds like a diesel...

Does the noise sound like a fluttery rattle and when you shift into gear it speeds up alot and changes tone but goes away after you drive for a while?

No...mine seems to sound like a diesel for a little while and then disappears.

I know what it is without a doubt

It is your Timing Chain Cassettes!! Without a doubt. I know this cause that is the same sound mine was doing just before 1, 2, and 3 misfired and im still in the process of doing the repair!!

mine too...

Mine went away also in the beginning. But after a year of doing that and wife running out of gas multiple times (How can I be out of gas, the red light never came on). Diesel sound started right side rear, then all hell broke loose July 19, 2012. Was taking my first vacation since 1997 and blew the right side on my way home from work to leave for vacation!

Yikes...my original motor blew 6 months ago and this motor is its replacement from a junkyard...I have a year warranty but wonder if they won't replace it as long as it's running.
