My Cadillac STS V6 has 115,000 miles and recently it started to jerk when I shift from park to drive or drive to reverse. I mainly notice it
when the car hasn't completely warmed up and I have to take off cause I'm late and don't let it warm up. This worries me cause I love
this car and want to preserve it as long as possible. Has any one had this problem?

An easy to way to check for a bad motor mount is to open the hood, have someone else get in the driver seat and rev the engine a bit. If you see a lot of movement when the engine revs there's a good chance there's one or more bad mounts.

I had my LF mount replaced last year sometime...Think it was about $450 all said and done. (local shop, not a stealership) I heard a distinctive pop/clunk when taking off from a complete stop if I was a little heavier on the throttle.
