I was told by someone long time ago that if you put the transmission in neutral during a traffic stop, it will save the transmission and prolong its life. Can someone tell me if this is true or not? I usually do this and it seems the car vibrates a little less(I have a 2006 X5 4.4i E53). My car isn't vibrate a lot but I can feel it when I stop at a traffic light in "drive". If I put it in neutral I can't feel it no more.

Thanks.
