Does non-moving A/T car consume more fuel if...

i actually read about this topic from an official Honda newsletter a couple of years back. it says that it doesn't really matter. It does not consume more fuel either way. however, it emphasized that you cannot place it in Parking mode while your car is running. Since this came officially from Honda, I assume the statement is reliable. However, I am not sure if this applies to other car manufacturers as well.

as i mentioned in another thread about a/t i do shift to neutral during long stop. if you are on d or p instead of n during long stop, the torque converter is in stress. coz inside it parang may dalawang electric fans na magkaharap, one is connected sa engine which is running and the other sa tranny. so kung pigil yung fan na naconnect sa tranny and the other is umiikot there's friction building up between them thru atf which translate to heat. but sa neutral iikot lang sila pareho kaya walang stress.
haay sana tama ako he he!

I usually put it in N rather than D in combination with handbrake never on P since naka lock ang gears kapag P pano kapag binagga ka accidentally from the rear this could damage your transmission. With regards to consumption i think pareho lang since di naman nagbabago rpm.

I put it into N as well then hit the hand brake if I estimate the stop is more than a minute or step on the brakes if less than a minute. I rarely leave it at D normally kung its almost going to be green or kung tinopak ako at ayaw ko magpasingit....
