People are already familiar with using a manual transmission gear boxes, also clearly know the best time to shift, using up handy. But for the automatic cars, people use this not easily. When using the automatic car, there are a number of the owners who lack of knowledge on the automatic transmission. They still use the manual transmission methods of operation. Finally, it caused the damage of the car and the threatened for the people. Even it will be buried accidents or cause the degradation of the function. The service life will also decrease. Following are some mistakes when using automotive automatic transmission, hope this can help the owners avoid the myth when driving.

Myth1:

When parking an automatic transmission car for a long time, the shift lever is still hanging in the D block.

When a car equipped with automatic transmission is in a wait-signal or a traffic jam, some drivers usually remain in the D gear shift lever, while the brake pedal, if the time is limited, it is allowed. However, it is best for packing a long time into the N block (neutral), and tighten the parking brake. Because the shift lever in the D block, automatic transmission cars generally have a little forward, if the long brake pedal depressed, equal to forcibly stop this forward, making the transmission oil temperature, oil perishable, especially when air-conditioning system working, the higher the engine idling more unfavorable circumstances.

Myth2:

When automatic transmission car is in a high speed or downhill, the gear shift lever keeps in the N.

Some drivers in order to save fuel, when speed high or in downhill, the shift lever to the N block glide, which is may burn out the transmission. Because the transmission output shaft speed is very high, and the engine idling, transmission oil pump insufficient lubrication conditions deteriorate, but also within the multi-plate clutch transmission, although the power has been cut off, but the passive film on the wheel, driven by high-speed operation, engine-driven active low chip speed, the space are very small, easy to cause resonance and slippage, it will leads to bad result. When taxiing long slope really need slide, shift lever can be maintained.

Myth3:

The automatic transmission gear starts the engine out of P and N.

Some drivers outside the P or N gear to start the engine, although the engine is not running (because the chain protection, only in the P and N block can start), but it may burn out the transmission neutral start switch. The automatic transmission is equipped with a neutral start switch. It Makes transmission only in P or N range to start the engine, which can avoid misuse of other gear when starting the car immediately started forward channeling. Therefore, before starting the engine please confirm the shift lever is in the P or N range.

Myth4:

Equipped with an automatic transmission or a three-way catalytic converters use automobiles method to start the engine driven cars.

Equipped with automatic transmission and automotive catalytic converters can not start because of shortage battery power, while using other vehicles pushed or dragged way starter, which is definitely wrong. Because the above method can not transport the power to the engine, it may damage the catalytic converter.

In the D block glide, but not the engine flame out.

Myth5:

Automatic transmission cars when parking on ramp are not using the parking brake.

Cars with automatic transmission when parking on a slope, some drivers just use the P block, instead of using the parking brake. It is easily leads to accidents. Although the car with automatic transmission gear parking in the P lock mechanism is rarely fail, once failed it will cause an accident. So it is safe for you using the packing brake when packing on the ramp.

Myth6

As long as Automatic transmission car start the D block, keeping increase the accelerator can change to high gear.

Some drivers consider that as long as Automatic transmission car start the D block, keeping increase the accelerator can change to high gear. But they don't know this is wrong. Because shift operation should be "close the throttle upshifts in advance, and advance the throttle downshifts" after starting in the D block, keeping the throttle opening five percent, accelerated to 40km / h, loose throttle quickly, can be increased to a gear, then accelerate to 75km / h, loose the throttle can improve a gear. Reduced by the speed of cars, throttle slightly, means back to low gear. It must be noted, the throttle can not step in the end. Otherwise, it will be forced to hang into low gear, which may cause transmission damage.

Anyway, the automatic transmission cars relative to manual transmission cars, eliminating the clutch pedal, does not have to frequently pedal, which makes driving simple and easy. However, use not properly, will artificially increase the automatic transmission failure rate, reducing its service life. Proper using of the automatic transmission, can not only to avoid or reduce the incidence of failure, but also reduce fuel consumption and reduce pollution.
