When you are driving and put an automatic vehicle in neutral why do the RPMS stay higher than idle?

This is the PCM (Powertrain Control Module) keeping the vehicle prepared for its shift back into gear. If the vehicle detects motion (by VSS signal or ABS Signal) it will keep the engine's RPM's Higher than normal to achive a smooth transition into gear rather than jerking or lurching the vehicle. This prevents damage to the transmission, and typically provides a smoother ride.

How often do people get transmissions for their cars?
One of the first clues that a person has to replace automatic transmission is that it is slipping. This happens when the engine revs higher, but the vehicle is not moving any faster. The vehicle may seem like the wheels are not connected to the engine, like the transmission is in neutral, and then it may catch suddenly, and drive under full power.
When you are driving down a steep grade in a vehicle equipped with a standard transmission you should use a higher gear to help slow your vehicle down?

What happens when sudden brakes are applied to the vehicle without using clutch?
If the vehicle is stopped without using the clutch , the engine will give jerks and turn off if the vehicle is in higher gear and the speed is not according to the range of the gear. Although, if the vehicle is being driven in higher gears and slight brakes are applied, no effect will be there if the vehicle's speed remains in the corresponding range. Example: if you are driving a vehicle at 90km/h in 5th gear and you bring it down to 60km/h by applying brakes without using the clutch, nothing will happen and you can continue driving by accelerating again.
Is it possible for a vehicle to go through a track if the first and second hill are the same size?
If it's starting on the first hill, in neutral, no. if its starting on a much higher hill, then yes.
How do you use overdrive in Toyota Camry 1999 automatic?

How does a car behave when it has transmission issues?
If a car has an automatic transmission, potential problems include:not shifting into forward or reversenot shfting automatically into higher gears when vehicle speed increasesnot shifting automatically into lower gears when the vehicle slows downnot downshifting to a lower gear to produce more power when a driver pushes down quickly on the gas pedalnot shifting into neutral or "Park" positionsnot starting in the right gear, or skipping gears, or failing to shift to top gear
Why does the 2001 ford escorts have two d's on the shift panel?
The " D " with a circle around it ( next to the neutral " N " position ) is the overdrive position . That is the normal position when driving the vehicle , it allows the transmission to shift into the fourth gear ( an overdrive gear ) when you are crusing at a higher speed . When it shifts into overdrive your engine won't rev as high , your gas mileage will be better etcetera
What number pH of soil is neutral?
pH7 is neutral, anything higher is alkaline, and anything lower is acidic.
What does a tach gauge do?
It indicates the engine RPM's (Revolutions per minute). Helps when driving manual transmission vehicle to shift at optimum rpms - prohibits engine "lugging" in higher gears. Also greatly assists with automatic transmissions when pulling a heavy load and climbing a steep hill ... It's a gauge that lots of people use more than a speedometer.
