lol at this whole thread!

1)take your foot off the throttle
2)pull the stick towards you(or the N) and let it go

it will do this at any rpm and any speed.

i coast in neutral from 80mph all the time to let the motor be at true idle but getting all
that air passing thru from coasting at speed to cool it down well the last mile or so to my house.

and it will reengage at any time as long as no foot on the throttle
i always reengage with my foot on the brake slowing down gently or when i fully stop

you are just putting your foot on the throttle or not holding the shifter over long enough. count to 3

You won't get the cooling action you want by idling. Despite clever designs, you still get much higher coolant flow volume through the engine at RPMs above idle than at idle. Air flow does little to cool this engine, the bay is designed to retain heat and channel all the airflow across the 7 (!) radiators it has to cool those fluids and thus the parts cooled by those fluids.

Granted that idling at 80 mph is better at cooling the engine off than idling at stop, but you'd really get much better cooling by just running the engine gently at more normal RPM as you approach home so you run more coolant through the engine and actually get heat exchange.

Just to confirm ... shifting to N while in motion and revving and then shifting back to gear will not harm the transmission? Genuinely interested as I've been told that was a terrible idea and would ruin the tranny.
