Coasting observation

[BigCars4Ever]

While heading down a particularly long steep grade I thought I would put my car in nuetral and coast a little and save some fuel. About halfway down I glanced at my tach and noticed it was a 2500RPM. I did not expect that the ECU would alter the idle speed to meet the drivetrain speed for the eventual drop back into drive.

In fact, click off the O/D and let the engine hold you back. Your brakes will love you for it.

I have a manual transmission in my truck, and it does the same thing. Tries to keep engine RPM at drivetrain speed for high gear.
