Putting automatic car in neutral when stopped

mikebai1990 · 08-06-06, 03:09

I'd like to see your opinions on the subject of whether or not an automatic transmission car should be put in neutral when coming to a red light. I personally don't have any knowledge or opinion on the subject, but I have seen some people do it with their cars. One side of the argument is that this way there will be less load on the car when stopped. The other side of the argument is that the constantly engaging from drive to neutral will cause more wear and tear on the transmission. Whaddya guys think?

Automatic transmissions are engineered to be driven with it in drive, including stop lights, etc. Shifting to neutral all those extra times will just cause the linkage to wear sooner.

Like velobard stated, the automatic transmissions are designed to be driven in stop and go traffic. Just read your owners manual. I know in mine, it specifically states that the only time that the transmission should be shifted out of drive (to either park or neutral) when the car is on is when the car will be stopped for an extended amount of time.

You lose an important element for bringing your vehicle to a stop by disengaging the transmission - engine braking. This practice will also increase brake pad wear because of the increased work perform without engine assistence.

Safety wish, you are in no immediate position to accelerate if necessary.

Foolish practice IMHO.

VERY foolish and VERY dangerous actually!

Perhaps I should mention that automatic transmissions are actually designed to be pretty tough, standing up to wear and tear FAR beyond idling in drive. When I was a test driver at GM they sometimes did abusive tests that involved putting the car in neutral, running the engine to red-line, dropping it in drive, spinning the wheels until you reached a line about 6' down the pavement, slamming it into reverse, back into drive, and repeating the cycle anywhere from 6 to 50 times. It was a good way to make a big cloud of tire smoke.

One guy I worked with passionately hated Corvettes after he had to do several of these 50 cycle tests in one. With the power and traction that 'Vettes have, he said by the 4th shift his lower back felt ready to give out but he still had 46 more to go.

Some people get all the good jobs!!

he said it was already at a stop.

But also, putting the auto car in neutral, doesn't that stop the ATF from churning?

This sounds like false logic one would derive from driving a vehicle with a manual transmission.

Please re-read the initial post carefully.

I wouldn't do it either- as others have said, the transmission is designed to stay in drive, it's smart enough to disengage when you're stopped. This just seems like a lot of the other "car advice" that seems to pop up everywhere with no real backing other than "it sounds good".

blkz28conv, I'm sorry for not stating this clearly, but I actually meant to ask whether or not to put it in neutral when at a complete stop. Sorry for the ambiguous original question.
