I recomended a Touareg 5.0 v10 TDI Driver to try coasting when downhill in a spanish forum.

But, some users of wich reported me that going neutral in Tiptronic automatic gaerbox will produce failure and "it's illegal in Somewhereland".

What do you think? Coasting will damage a torque converter automatic like Tourag V10? If you know Self Study Programs, Toureg's v10 gearbox is "ssp 300 6 speed automatic" where you could find technicaal description.
It has when full throttle: 500 Nm at 1000rpm and 750 Nm at 2000 rpm.
It also has large gearings 6th gear 1000rpm speed is 60 km/h, so neutral to drive transition at 120 km/h it will need 900 to 2000 rpm change.
Reving the engine to 2000 rpm will help? Tiptronic could be used lique a sequential box in the "maual" mode so is it posible go N to D in 6th?

It's neutral so bad when stopped in a red light?

I've heard the same hurt thing if you wait the green light stopped in Drive and pushing de brake pedal? I've tested only two automatic gearboxes ( peugeot 1007 automatic and Honda Insight' 2010) both of them started to move when I released the brake Pedal when D was selected.

Maybe so many questions, hahahaha
