Coasting
I was wondering if it is bad to coast in neutral down gentle hills. I like to coast on my way home at night. It's usually around 8 or 9 pm and traffic is light. I don't do it if someone is behind me. Is it bad for the tranny or anything else? My ford is a 94 F250 with E240D.

For all practical purposes the E4OD does coast down hills, as long as the OD off button isn't pushed it don't hold back.. You have to use the OD off button to get it to hold back going down hills..
Just be damn careful shoving the shift lever up to neutral, you can kill a mighty expensive transmission if you miss and put it into reverse!!!!!

I did that once with my parents '75 Buick Century wagon. Rear wheels locked, chirped, quickly stalled, and then continued rolling. I thought I killed it, but it just started up and I drove home without issue. Still haven't told them to this day.

Back when I was younger and a bit more stupid. I used to do that intentionally in my first truck. throw it into R going 35 or so, hit the gas and break the tires loose, just keep em rolling backwards until the truck was doing 10 or so in reverse. Then I'd go back into drive, brake em loose again and just take off down the road.
I'd never do that in any of my vehicles now, but that E4OD got 240k miles on it before I wrecked that old truck, then we took it out and put it into a 3/4 ton plow truck and it's still going strong.

It might if you rode the brakes the whole way, but then if you do that, what's the use of coasting?

Nope, no stopping unless I get the light coming into town. I have it figured out where I can start coasting. I shift to neutral and pass 2 speed limit signs a few miles over and coast 1/2 way through town. Then I shift into drive and maintain 25 until I get home.

isnt there an overdrive clutch that stalls when you lift the throttle anyway? i guess i never do it cause i havent found a hill that could overcome the air resistance yet, including the black hills so i guess i never do it

If you're coasting downhill in neutral at highway speeds in an effort to increase fuel mileage, you're likely doing the opposite. The coasting fuel shutoff parameters in the EEC will cut fuel when coasting at those speeds with the TC locked and the trans in gear. By putting the trans in neutral, you're keeping the fuel injectors on, albeit at idle rpm, during the time that you're coasting downhill.
