Just a question for those who understand automatic transmissions. One hypermiling technique I've heard of is to get up to speed, drop to neutral and coast to lower speed. Then go back into gear and get back up to desired speed...
I have no idea as to whether this is effective at all, but it begs one question before even attempting. Will this harm an automatic transmission?

Re: Hypermiling and the Tranny
Ah, the pulse and glide technique. While I use a lot of hypermiling techniques, this is one I don't do. Too much work. I do quite often use neutral to slow down in traffic then put the van back in gear. No problems with either transmission so far.
