I've found an automatic that doesn't like neutral coasting

It's pretty common for people to react with irrational fear when someone proposes using the 'N' position on an automatic. Most suggest that the transmission will break, which is just not the case; the way 'N' works is pretty much the same way the transmission always works as it shifts between gears anyway. One person recently suggested that idle speed at the input shaft is just not enough pump speed to keep the transmission completely cool, and that has been the only argument that has convinced me that there could conceivably be something to worry about.

Consider my wife's 2000 Isuzu Rodeo. It's an all around awful vehicle; I blame this partly on bad design and manufacturing by Isuzu, and partly on it beinig a rebuilt salvage vehicle (we got it for free, so really...can't complain too much!). It's got a V6 and a four speed automatic. She was practicing P&G and getting 22mpg (up from 18) when her "A/T Temp" light came on. She does not do it any more.

So there you have it. Finally there has been an actual data point showing that one vehicle's automatic doesn't like neutral coasting at speed. It didn't break, it didn't blow up, it didn't eat babies...it just warned the driver with a light to say "don't do that".
