My 1998 accord starts in neutral I tried it today.

Overheating the transmission is a real risk..


Need an AUX pump to keep the fluid moving and lubricating..

Never turn off an automatic transmission to coast. The little fuel consumption savings aren't worth the cost of transmission repair or replacement.

And since we're on the topic of starting in neutral, my '04 Civic auto I used to have would not start in neutral.

I am a big fan of EOCing....a manual.

I am not at all a fan of doing it with any auto. Even if it does not harm the trans.

It simply comes down to the fact that manual restarts can happen in an instant to restore power steering/brakes. It takes longer with an auto, if it is possible at all.

The only way I might consider it is if there was no traffic around me at all.

Any car that the factory designed to be flat towed can coast in N engine off without fear of damaging the tranny. Cobalts are and I think the models before it were as well, back to the Saturn SL's. Electric Power steering the in Cobalt address the other issue.

The 2010 turned it's self off driving down the highway with cruise set at 55 a few days ago, just slipped it into N hit the key and it's running again.

I had an issue coasting in my (now ex) wife’s 2006 Ion, using the 4T45 transmission... in theory the transmission can handle it but the car wasn’t programmed to accept the car moving and zero trans pressure (from engine off) as an acceptable condition so it threw a code and put the trans in some kind of limp mode... I cleared the code and the trans went back to normal but I learned that day that not all vehicles can be EOC’d even though their components *should* handle it...

2010 cobalts were part of the ignition recall iirc

My 99 Saturn was supposed to be fine for flat towing, only issue I found was that the cruise control didn’t work if I eoc’d w/o coming to a stop, until the next time I actually stopped.

Yeah the cobalt have had their ignitions replaced, thinking back on that occurrence, there is a pretty big bump in the road right there and I have more keys than normal on my key chain, and that key is a fairly new walmart replacement, my son has been driving it with the original key and fob only and no reoccurrences. It also had a car with lock show up on the dash around that same time that I think is gone now.
