3. TL Says: no

4. billy25685 Says: There is no reason to put your car in neutral at high speed. Unless your motor dies, in which case you throw the tranny in neutral and start braking to the side of the road.
Anybody who at high speed likes to throw it in N and then back to D deserves whatever happens to them and their car.

5. randyrayd Says: I wouldn't do it repetitively.

Now, if you are accelerating and popping it back and forth, Drive to Neutral, so it sounds like you have a five speed and your getting scratch between gears, then it will tear the heck out of the transmission.

6. bobweb Says: No, your owner's manual does not say it's harmful and you can shift between drive, overdrive and neutral as you wish at highway speeds from my learning and experience.
