my 2005 300c has had a drive train vibration since new. I had the tires rebalanced with no change. It occurs only at 1750 rpm in overdrive. Has anyone else had this problem??

ahh shux thanks for the boost of confidense

anyway what gear do you think its in i know they have a 3rd to 4th gear shudder with the nag1 trans
its got to do with water in the trans they do a complete flush and it should fix it if it is.
other than that i am going to start to inquire on this one.

I had the same issue, dealer stated moisture was getting into the transmission via the fluid fill tube. Problem was corrected, shutter went away, but at 5800 the torque converter and pump failed. Not sure if related but the car has been down 15 days due to unavailable parts.

Zilla,

Thank you very much for this information! I am headed to my Chrysler dealer this morning to show them your information. This issue has bothered me for three years so I hope this resolves my problem.

Thanks again,
