Any damage to auto transmission when coasting in Neutral

Question is for my 99 Saturn SL2 Automatic

I don't drive in an area that will allow me to pulse and glide. I can't even do any decent pulse and coast since the roads in metro Detroit are relatively flat and I drive during rush hour traffic.

My general question is ... can you harm an automatic transmission by frequently going from D --> N --> D, in an aggressive pulse and coast strategy.


Personally, I don't plan on doing this very often but there are a couple of instances where I can coast any where from a 1/8 to 1/4 mile.
