So far, so good, although the car did "jolt" or "kick" while idling yesterday. It just happened once and wasn't severe, but it was noticeable and seemed to be transmission-related. I'm going to keep an eye on that.
I'll bet if you lube the slip yoke on the propeller shaft (drive shaft) that clunk will go away.
Manual calls for lube at the scheduled oil change interval, but I like to lube it up more frequently.
That jolt/clunk thing can be concerning when you first feel it. You can feel it when the tranny is shifting as well.
