Is it safe to use neutral while you are coasting (engine running)? I know it's really bad to coast while the engine is off and in neutral with an auto because the trans oil pump is not spinning. But if the engine is running and the car is coasting and in neutral the oil pump is spinning. But does it spin fast enough at neutral to provide adequate lube? If this does not hurt the trans then this is a great way to save gas. Not to mention, it's easier to stop.
