Backing out in Neutral from Garage without engine on safe for the transmission?

Hi Everyone,


Theoretical question for you all. I live in a newer house with a single garage, but I don't want any exhaust lingering in there any more than there needs to be. I don't notice anything unusual with gas being trapped, but just as a safety habit in general (and since I didn't build the house, do the drywall, etc...who knows if any off gases could actually still enter from somewhere I can't see).

I'm wondering then, since my garage is slightly sloped out for drainage: could I simply back out the car by putting it in neutral and then, once outside, turn it on? I don't want to cause any damage to the transmission or what not (and yes, I know that by doing this, I would have no power brakes). I figure this would minimize off gases in the garage but if it's going to wreck my transmission or something...

Constructive 2 cents are always appreciated!

Mr. Gisa

yes. It is fine, it is in neutral.

Get the house leak tested for gas if you are that concerned.

First off.... just back out. It won’t cause harm...

Second. Don’t. Just don’t. If it’s a standard sure. But even then I don’t recommend moving With no resistance.

You won't hurt the car, just like you won't hurt your house or anyone in it by starting your car in the garage.

Yes you will ruin your trannny. If you start your car you will kill your family from CO poisoning. Just buy a tesla or ride a bike. Better safe than sorry. Grinning Face

Am i missing something? Why not open the garage door before turning on the car? if you are nose in and the garage door is open then you immediately back out once starting the car, how much 'gas' are you leaving in the garage?

Going to run over an unfortunate pedestrian crossing in front of your house one day. No sound, no power assist to brakes.

Just buy a good carbon monoxyde detector. It is a must if you have a fireplace, or a garage attached to the house.

And, like other said, open the door, get your car out and you're done. It'snit afew seconds that will get your family poisoned. And, if your house been built respecting regulations and the code, there is no issue, as long as the car doesn't run for a long time with door closed

I do that all the time. Honda Accord transmission is fine after seven years of doing that.

Of course I only roll the car back onto the driveway and no further, put back in P, pull up the handbrake and start the ignition.

I don't close the GDO immediately and one time let a racoon in lol.

Brilliant minds think alike.

Don't you have a door between the garage and house?
Or a co2 detector?

I'm sure people are inhaling more co2 in rush hour traffic than in garage.

If you have co2 detector with measurement , compare your garage reading with your mechanical room. You might be surprised with the outcome.

It is CO not CO2. Carbon Monoxide not Carbon Dioxide...huge difference

CO is a product of incomplete combustion and is very lethal, CO2 is fissy bubbles in cola

I do this all the time. There's enough residual pressure in the braking system to stop on the driveway once out of the garage and no harm to the transmission.

How slanted are your garages? Cause shit I'd have to sit there in neutral and probably wait 30 secs before the car builds enough momentum to roll backwards in neutral. That said the only time I back up my car in neutral is when my kid is asleep as my car is a tad loud and the noise vibrates through the house lol
