Pointers on shifting gears
published: Sunday | October 19, 2008

Paul Messam, Gleaner Writer


The interior of a manual-drive car.

THE FUNDAMENTALS of control, like the table of elements in chemistry, are the essence of driving, says Norris Christian, an accredited driving instructor, as he spoke with Automotives about various elements of driving a vehicle with manual transmission.

In controlling a car, we do not refer to the ability to parallel park or make a left-hand turn at an intersection. These elements of driving are important, but they must be subordinated to such essentials as steering, braking, gear changing and cornering.

Driving a motor vehicle with a manual transmission requires coordination with clutch, accelerator, and the gear shift lever. The clutch pedal must always be pressed down to the floor before starting the engine, before shifting and before coming to a stop.

Depressing the clutch disconnects the engine from the wheels and takes the car out of gear. At other times, when driving, it is wise to keep your foot off the clutch pedal. The habit of riding the clutch, driving with the left foot resting lightly on the clutch pedal, causes needless clutch wear, Christian cautioned.

Mechanical components

He explained the mechanical components of manual-drive vehicles.

Some stickshift cars have a three-speed or a four-speed shift pattern. Others have five-speed pattern. The three-speed pattern usually has the lever mounted on the steering column.

The four-speed shift pattern usually has the gear shift lever on the floor. The fourth gear is intended for use at higher speeds and on the velvet highways. Since the fourth takes less power to keep the car moving, it uses less fuel.

The instructor pointed out that shifting should be done smoothly form one position to the next and always with the clutch depressed to the floor.

He, however, advised motorists that the speed given for shifting are only intended to be guidelines.

Check the owners manual for your car because transmissions vary greatly, he added.

Using stick-shift gears

The NEUTRAL is the cross bar of the H in different patterns. A car should be in this gear when standing still or when starting the engine.

FIRST This gear is used to start the car moving up to a forward speed of, say, 10 to 15 mph (that is, 16 to 24 km/h). First gear can also be used for driving up or down very steep hills, for driving in mud and for pulling heavy loads.

SECOND This gear is used to bring car up to a forward speed of 15 to 25 mph, which is 24 to 40 km/h. This gear may also be used for steep hills and for driving in snow or ice.

THIRD This gear in a three-speed transmission is used for steady forward driving at speeds above 25 to 35 mph. The equivalent is 40 to 56 km/h. In a four-speed transmission, third is used to accelerate to speeds up to 35 or 45 mph (56 or 64 km/h).

FOURTH The fourth gear is used for speeds above 35 or 40 mph (56 or 64 km/h).

FIFTH In some motor vehicles, this gear is also a cruising gear for higher speeds, for example, when travelling on a highway.

REVERSE This gear is used for backing the car. It is prudent never to shift to reverse when the car is moving.
