70 percentage automatic car owners neglect of misuse, no matter how good the gearbox 2, also spent three years!

Because of the high degree of automation automatic transmission vehicle without frequent shifting, convenient and simple driving operation is not easy to stall and other advantages, automatic transmission models more and more consumers of all ages, and now, more and more people are automatic start buying the car.

Many people think that automatic transmission cars do not need to artificially shift, the truth is that right? of course not. As the name suggests, without automatic transmission is manually shifted to the driver, the vehicle will automatically select the appropriate gear in accordance with the speed of travel and traffic conditions. When driving on normal roads, we do not need artificially to shift. However, when the vehicle is on a downhill or parking, the driver is required to manually shift.

But if you know how to drive automatic transmission shift it? In the shifting process should pay attention to what the problem? These are clear you understand? Is it because you misuse shift, inadvertently caused his car to some unnecessary hurt? Today, here, we have to talk about, how to properly drive automatic transmission cars should shift?

in the general range of automotive automatic transmission has six positions, respectively, from top to bottom: P (parking range), R (reverse gear), N (neutral), D (Drive) , S (sport mode), L (low gear).

a lot just by driving school exam owners, while driving automatic transmission car, you may not know a lot of places will appear in the shifting process, for example in the shift, under what circumstances need to hit the brakes shift? Can you suddenly shift into low gear and other issues in the car at high speed? Here today, with the majority of our faithful car exchange ideas on these issues.

First we will describe a problem, that is, whether or need to hit the brakes when the automatic shift it? Under what circumstances, you need to shift the brakes?

First, the point to note is that the shift is not necessarily automatic transmission brakes. Only when the other gear engaging the P range, the shift is enforced we brakes for shifting. Each switch between other gear is not absolutely necessary step on the brakes. Especially when the vehicle is climbing, when engaged by the D-range and low-grade, had the car speed is not high, limited power, then step on the foot brake, the car might stop running. But valueIt is noteworthy that, when the D range and R range switch to each other, in order to protect the vehicle power system to the brakes until complete standstill.

when we drive automatic transmission vehicles, the shifting process, we generally what issues need attention?

First of all, we should note that, when the vehicle is in a deceleration or downhill, do not change the N range to glide to the fuel. This is because after the change into the N range, the transmission oil within the transmission only by idling the pump supply to meet local lubrication state when the vehicle is stationary. While the vehicle is running, the need for adequate lubricant in the D range or other drive mechanism, so that all the multiple disc clutch and transmission gear can be lubricated. Otherwise, over time, gradually within the automatic transmission will be damaged due to insufficient lubrication. Even more dangerous is to change into N block fuel-efficient, automatic transmission that will really burn out due to insufficient lubrication pressure, or loss of power caused by the disaster of control when going downhill.

here to remind the owner, because each forward gear automatic transmission has its maximum speed limit. When the automatic transmission car driving at high speeds, do not suddenly shift into low gear. In other words, at high speeds is not to push the shift from the D range to any profile of a 1,2,3. Otherwise, it will cause serious vehicle accidents.

When the automatic transmission will be parked into the parking space, when the car stops completely, do not rush the gear change into the R range. This is because when the car is not completely stopped, if the gear change by the R position D, will produce an instant ldquo; counter-rotating pressure rdquo; toward the reverse clutch plate, so that the operation time, the clutch plates will result in excessive wear.

It is worth recalling, the owner not to random automatic car trailer. This is because the car fails, automatic transmission oil pump can not operate the components lack of lubrication and proper cooling, when the driving wheel, the wheel will drag when the car was dragged, and therefore transmission will operate together, after dragging some distance, they It can damage the transmission.

If the automatic car due to lack of electricity can not start, do not try to push employers with ways to deal with manual transmission car, it will not only damage the transmission, but could not push the start . The only way is to use the rescue ldquo; rdquo help line; Across other vehicles power to help start. When

failure of the automatic transmission car needs to the repair plant, the trailer is best to operate the driving wheel lift and drag, otherwise it will damage the gearbox.

open automatic transmission car owners must pay attention to that, not after the winter cold start, no warm up the road immediately and fierce acceleration. This is because if the engine is started cold to warm car, each part of the body will accelerate wear and the formation of internal injuries. Transmission oil in the automatic transmission oil temperature rise also need to warm up to normal temperature after, to make the components work without mechanical wear and tear. High cold car idling, usually not more than 1000 rev / min, then if started, will result in start shock. If you can not warm the car, but also gentle start, use warm-amble section of the road, a road to avoid pedal to the metal.


In the automatic transmission when the vehicle is long steep, if the slope at the long, not the car has been linked to the D block. This is because the car at the time of the long steep road, if you hang in the D range, transmission shifts very frequently, so that the transmission will be greatly impaired. Brake should pull over, hanging files 1, 2 or 3 then start, depending on the specific circumstances of the specific file which may be hung. Such as general manual transmission car 2 files can be up slope, the automatic transmission has been busy, then placed on top of 2 files should be right. If the length of the steep ramp next, if you hang in block D, need to have a vehicle brake control; if used frequently prolonged braking, the brakes may overheat and efficiency is lowered, when this happens is very dangerous;

in addition, it is worth reminding that many mountain roads unpaved, gravel slam on the brakes more dangerous. Here should be the correct method, the first brake pull over, 2 or 3 linked to then start block, because it can limit the vehicle speed of the automatic only on low, so that the car can be used for engine power during downhill braking , the driver brakes unnecessarily long brakes cause dangerous overheating. On larger heavy congestion situation and this slope ramp-gear to perform their functions best way, because it can take advantage of an automotive engine torque at a slope or lower slope.

Summary: drive automatic transmission vehicles fat faithful, we must be careful not to hang up on the downhill when the D position, nor could fuel the next tag through the gap. All in all, the shift must pay attention to the things we have mentioned aboveitem.
