As for the comment from dfw123 on neutral coasting...
I see no reason coasting in neutral would be damaging to the FFE. The transmission gears are turning any time the cars front wheels are turning. The spinning big gears lubricate the transmission by throwing the oil up on all the gears(& bearings). I am not sure if the bearings are sealed or lubricated by the splash. But the first gear has visible rollers in it in the parts diagram leading one to assume all the bearings are lubricated by the splash.
In a front engine, rear drive, manual transmission car, pushing in the clutch(or shutting off the engine and putting the shifter in neutral allows the transmission counter shaft to stop, this stops the splash lubrication of the transmision, especially to the upper main shaft. Failed transmission is next, usually starting in the mainshaft to input shaft bearing. Automatic transmisons of the same setup need the engine running to provide the lubricating oil for the whole transmission. Coasting down a hill very fast with an automatic in neutral and engine idiling would not provide as much lubrication as was designed to all the disengaged but touching clutch plates because the pump is turning slowly with the engine. (Not fast as the drive shaft would be turning the engine faster). There are many spins on this issue and front engine, FWD cars are a different breed and have many more options for oiling or not. I see none of these problems with the FFE as long as it has oil in it. We have bought 2 new Mustang Cobras over the years. I found the transmission oil level extremely low in both cars when getting them home from the dealers(different dealers for both). I plan on checking the FFE soon. It is a pain getting to the plug.
