What is the difference between automatic transmission 1st and 2nd gear and S and L gear

l is a low-speed gear. It is generally used when climbing steep slopes. It will be easier than D gear. It is also used when going down a long slope at high speed. Equivalent to a manual transmission - a low-speed gear"Don't drive"Action.

S is the sport mode, and the shift speed will be higher than the normal mode, so the car's power performance is sharp. But in this mode, the fuel consumption is also high, although it is very cool to drive.

The 2 and L refer to the low-gear mode of the gearbox. In L gear, the gearbox will be in low gear, unlike in 2nd gear, in L gear, the gearbox will be raised to 3rd gear. In the case of a 5-speed automatic transmission, in normal forward mode D, the transmission forward gear will jump between 1-5, while on 2, the transmission will only jump between 1-2 and will not rise to a high gear like 3-4-5.

When going down a hill or going down a long-distance slope, hang the gear on a low gear like L, which can limit the gear of the car to automatically only be in the low gear, which can make the car use engine power to brake when going downhill, and the driver does not need to step on the brakes for a long time to cause the brake pads to overheat and cause danger. It is most useful in situations of severe traffic jams and on slopes with large slopes. When going up or down a slope, you can make full use of the torsion of the car engine.

Generally, the gears of automatic transmission vehicles are p, r, n, d, s:

p Parking gear. When the car is parked, the gear selector lever must be pulled into the P position.

rReverse. n Neutral. The n position is equivalent to neutral and can be used when starting, when people are not leaving the vehicle and parking, or when towing a vehicle.

d Forward gear. When driving normally, the gear selector lever is placed in the D position, and the car can automatically shift between the forward gears. D is the most commonly used gear.

S gear is the sport mode of the car ( S is for Sport"In the S-gear sports mode, the gearbox can shift gears freely, but the opportunity to change gears is delayed, so that the engine can be maintained at high rpm for a longer time, so that the car can travel at low gear and high rpm for a longer time, and then obtain greater torque output and acceleration. When the car is moving, it is sufficient to push the gear knob directly into the S" gear, which is usually used when climbing hills and overtaking speeds quickly.

The S gear on the automatic transmission, in fact, there are two situations, one is the manual mode, the other is the sports mode, but now the vast majority of the S gear is defined as the sports mode, and the L gear is actually a low-speed gear, if the automatic transmission has 6 gears, then this L gear is actually as long as you are not hanging in the D gear, then it will switch between 1 to 5 gears, and will not reach the highest gear, so we have to distinguish these two gears.

Secondly, let's talk about "+" and "-" This is actually a manual mode, some will even write an M for you, and then there is a "+" and a "-" and some models do not write anything, only one "+" a "-" But this is also a manual mode, generally this is used in steep slopes, we can directly hang to the manual mode, so that we can ensure that the engine has enough power to climb or downhill when using engine traction to ensure driving safety, After all, it will definitely not work with the brakes alone.

Hello, L gear is a lock gear, for example, the L1 car will continue to lock in 1st gear and will not automatically upshift. S gear is a sport (sport mode) and is different from the D gear (forward gear) shift strategy, and the acceleration performance is better.

Features are different:The S gear is a sports gear, the gearbox shifts delayed, the engine is maintained at high revs, and the acceleration performance is good when overtaking. l Low gear, hang the gear here, can limit the lowest gear of the car, so that the car uses engine power to brake when going downhill, and the driver does not shout that it is necessary to step on the brakes for a long time to cause the brake pads to overheat and seep into the land.

S gear is a SPORT gear, as mentioned earlier, the automatic transmission car will automatically upshift or downshift according to the vehicle speed, throttle depth, etc., which is a program set by the manufacturer. This balances driving comfort with fuel economy.

Precautions for car S gearSecondly, don't put in S gear when cruising at high speed. The S gear will stay in 3rd gear for a while, and you will not be able to go up to 6th gear. That's up to 90 kilometers per hour, and it's accompanied by the sound of the engine revving in the red zone.

Such a toss is very "blue and thin mushrooms".

The difference between L gear and S gear is that L gear is a low-speed gear, and S gear is a sport gear. In terms of function, the L gear can be used to control the speed of the vehicle, climb heavy loads, mud driving to increase traction, while the S gear can be used for overtaking acceleration and fully release the power of the engine.

S gear is the car's sport mode ( S is for Sport"Many automatic cars are equipped with S gear, and some high-end models of A-class cars also have S gear design, S gear sports mode, the gearbox can shift gears freely, but the opportunity to shift gears is delayed, so that the engine can be kept at high rpm for a long time, so that the car can travel at low gear and high speed for a long time, and then obtain greater torque output and acceleration.

The latest statistics show that every five people own a private car. At the same time that the car is widely used in ordinary families, the popularization of car knowledge is becoming more and more important, many car owners because they do not understand the car, and often make many jokes in daily life, just like these misreadings of the S file, in fact, the S file is what we call sports.

In S mode of sport, the gearbox can shift gears freely, but the opportunity to change gears is delayed, so that the engine can be maintained at high rpm for a longer time, and the high torque is output immediately, so that the vehicle is more powerful.

There are six gears for vehicles with <> dynamic gears, of which there are four commonly used gears, namely P, N, R, D, and L and S. So what's the difference between the L segment series and the S file?

1. There are many differences between L gear and S gear, not only the use of different scenarios, but also the power output of the engine when the vehicle is driving, the details are as follows:

2. L gear is often referred to as low-speed gear, when the engine is limited to a lower speed, more sufficient power can be obtained; Generally, when going downhill, it is more suitable to use L gear, which can use the anti-drag brake of the gearbox to control the speed of the vehicle, thereby reducing the burden of the vehicle's brakes.

3. S gear is often referred to as high-speed gear, the vehicle in this mode has very strong power performance, but there will be a delay in the shift time, which can keep the engine at high speed for a longer time; Generally, the vehicle is used to hold filial piety when overtaking or climbing, but the fuel consumption of the vehicle will also increase.
