this is one of the weirdest threads. first of all, why would you want to do that?
as for facts, when ur driving on the freeway and let go the gas and put it on neutral and then shift it back to drive, ur tranny should be fine. cz there is no pressure on the tranny at all if ur not revving.
now when it comes to revving the engine in neutral and then shifting it to drive, now ur asking for trouble. before anything, you would hear ur car go like goom. that will mess up ur tranny depending how bad you did it and will fuck up the engine mount. simple as that.
as for burning out on automatic cars, the stupidest way to do it is putting it on neutral and revving it and then shifting it straight to drive. you fuck up hardcore, you hear a crack noise and you dont give a damn wut the noise is? its ur mount and ur tranny taking too much stress. for all you rooks who WANNA burn out with an auto, either put some torque on ur car somehow, or else put it on 1 and hold on the brake and rev as much as you want and then let go. you can work with the emergency brake depending on the road condition and wut you trying to do.
NEVER shift an auto quick, NEVER rev on neutral and shift to gear. ur gear changes must be smooth or else you damage ur car unlike manual trannys. wait til you drop to 0mph and 750-1000rpm and then shift. dont shift straight from R to D while ur car is moving, brake as much as you can, shift to N and when you feel ur car is almost frozen shift to D.
