Using DFCO to increase your MPG

[sickpuppy1]

That being said, I don't know why, but I always wonder if putting it in neutral and coasting is bad on the tranny, any thoughts, remember its an AT

It is not recomended that you put your transmission in neutral if your transmission is automatic. The transmission could overheat because there are no oil moving in the transmission if in neutral. Manual transmission dont have this problem.

If someone could confirm

I was always taught that moving the transmission from neutral to drive while moving could damage the transmission. The only place to move the tranny is from a dead stop.

Might be urban legend....might be for old trannys that were made by Govt. Motors back in the day....but my Dad taught me this and he was a Mechanical Engineer and I always thought his words were the rule!

So it is my rule!

i have a early 2007 automatic yaris sedan, manufactured in june 2006. can anyone explain what this means, i copied it from the first page of this thread:

"Early versions pf the AT (Including ones sold in the U.S. until around January 2007) can only achieve DFCO with a gear selection lower than (D)rive, i.e. 3 or L, but since half way through the 2007 model year the AT can achieve DFCO in all gears.."

does this mean when i drive around in D that i am never in dfco mode, or does it mean that the dfco only kicks in as the vehicle slows down coasting in a lower gear than D (even though my shifter is still in D)? thanks
