Normal Or Abnormal?
Yesterday I was caught in a stop and go situation in my Bluetec for the first time since I took delivery.It was on an Interstate and went on for about 10 miles.What happened...at least two or three times...was an abrupt and very strong "clunk" coupled with a split second of shaking when braking (or coasting,can't recall which) from,say,15mph to about 3mph (not to a complete stop).I assume it was a down shift (I certainly could be wrong) but it was certainly unlike anything I've ever eperienced in any car I've owned...including my recently "departed" BMW diesel (6 speed automatic).I've also experienced a kind of "herky jerkey" phenomenon...seemingly transmisson related...a few times,also at low speed.
Thoughts? Should I persue this or am I just a worry wart?
