Your service manager probably wants your money when you burn up the tranny.

The tranny gets it's lubrication pumped from the spinning of the engine. When you put it in N and shut off the engine, the drive shaft is still spinning gears inside the tranny. This is why in manuals they say the car should never be towed above 25-30 mph for short distances in N with out the drive shaft pulled out.

Leaving the engine on and coasting in my '90 Firebird along with other driving style changes shot from an average 12 mpg to 20 mpg. Keep the engine on and keep cash in your pocket.
