transmission mount torque spec
2011 GLK350 4matic has vibration when coming to a stop and at idle. Will replace rear transmission mount this week. Greatly appreciate if someone can clarify the torque spec for bolts of crossmember, mount to crossmember and mount to transmission. Thanks.

Johnny, thanks for the spec. Do you have data for engine mount bolts and the flexdisk bolts? While doing the transmission mount, I may need to replace those as well depending on the wear condition. Thanks.
