When going downhill with your foot off the accelerator pedal, is there any link (direct or hydraulic) connecting the drive train to the engine? For example driving down a steep hill at about fifty miles and hour with your foot of the gas. Will the engine remain at idling speed, or will the drive train cause it to speed up? I know that in manual trannies, with the clutch engaged, the engine will cause the vehicle to slow down when going downhill.
