A Few days ago, I was cruising down the expressway at about 70Mph, with
cruise engaged, and all of a sudden felt and heard something that that
seemed like the rumble tracks on the shoulders of the highway, but
there was nothing in the road, and I was in the middle lane. Any ideas
what this could be?



Another thing I have noticed is sometimes, in proximity to a shift
(either before, during or after), I hear something that almost sounds
like friction material slipping. Not sure if that's what it is, but
it's not consistent.



Any ideas on these?



Thanks.
