Coasting in Neutral is damaging???
Coasting in neutral is not damaging. I think there might be some confusion here. Something that will cause excessive wear on your clutch and tranny is holding the clutch in while in gear and coasting. Idling or coasting in neutral does nothing.

You really can't do serious damage to a manual, unless you're jamming gears all the time. A manual tranny is just a bunch of old fashioned gears that can be filled with 30 weight once and then pretty much forgotten about, and the only brunt of stress and possible failure is the clutch. There is no need to worry if there is oil circulation or not, because the oil only circulates when the gears are moving, and doesn't need forced circulation, unlike an automatic, which has vaccum lines, and a hydraulic torque converter. Coasting in neutral with a manual will do no more damage than driving in fifth gear. Coasting in neutral with an automatic can cause vaccum and ecm problems. Especially now with computer controlled trannies which use speed and engine rpm inputs to optimize performance and efficiency. The computer may tell the transmission to do things it can't do when it's in neutral.
If you were "coasting" at a decent speed, say 35 or 40, and then shifted back into gear, could it damage your transmission at all? I imagine it would be worse for an auto that a manul, but what do you all think?
Just match the revvs up and it will be fine, in a manual... Keep in mind, while we're talking about coasting in neutral, believe it or not the car uses MORE fuel to coast downhill in neutral than in gear. Yeah it may slow you down but the fact is it requires fuel to keep the engine idling (coasting), whereas if it's in gear and the engine is spinning faster than 1200rpm, no fuel is injected. Kinda makes sense if you think about it...
