Maurice - I think that may be it. Here in D.C. it gets hot. I'll have to see if it's temperature related. It only happens ONCE, ater you start the car and go onto "D". I also noticed it never hapening while going into "R", but it does happen when going through "R" to "D", i.e. I pull out of a parking lot backwards, then go into "D", and oops, she's on strike. And once you are past this hesitation, you are ok. Very strange...
