its the upper motor mount connected to the block on the drivers side......I see that the motor mount itself is intact but the dealer claim that the metal piece from the block to the motor mount is broken....also the bottom mount on the same side has the bolt fallen out..i got it back in but the rubber mount has this bolt going through now no longer sits in the middle....I'm still skeptical about this...if the mount actually broke..wouldn't the car shake at idle???and at all times???....the car jerks when I shift or when I'm crusiing...I got different opinions from others..some saying its engine related and some say its the transmission...and the dealer say its the motor mount....bottom line I don't want to spend boo koos and get fuked at the end.....suggestions guys?????
