Re: Any shutter On newer builds
My KL was built in June 14, and it shuddered (wobbled ) from day 1. Now at 2000 miles, still wobbles at 1800-2200 RPM, 2nd to 3rd gear shift when the trans is over 150 degrees. Had the software checked, but I have the latest. So the next step is the replacement axles and a new trans mount. But many others say they went this route and the wobble comes back in about 300-400 miles. Some have even had the entire trans replaced, and the wobble remains. One owner said his tech put in 4 washers under each of the 3 engine/trans mounts that lowered the entire transaxle and changed the geometry of the axles. Initially this worked, but I haven't heard back if that solved the problem. Many people have been told there is a bulletin #S142100022 that has 13 steps to try to have this wobble fixed.
Others with a build date in June also have this problem, so it's still out there.
