"this document" so i go into my dealer and go i know "this document" about driveline/transmission? weird lol im confused on what i should talk to my dealer about
and i have brought it in once befor acouple weeks ago and one of there techs drove with me and he felt it too and i brought it back down acouple days later to have it checked out
they ran a full test on it he sereched for recall parts ect ect found nothing
then they had a white 1LT RS on the lot i took that out for a test drive and felt the same vibration but not nearly as bad as on mine so its a mystery
so what would you suggest if i brought it back to the dealer to ask or tell them to look for?
