Automatic transmission tips trick to protect the car engine

It is only possible to start the vehicle in two gears, p and n. To remove the gear lever from p, it is necessary to apply the brake. The use of n-speed start-up is when you directly drive forward after the vehicle starts, you can turn on the power first, hold down the brake and pull the gear to n, then ignite, and then hang in the d-file directly to avoid running. After ignition in the p file, you need to go through the r file to make the gearbox go through a reverse impact! This is a little better, Ha ha Another role is that in the event of a sudden stop in the drive, you can quickly ensure the safety of the stall to n stalls and then start the engine.

Normal gears do not need to press the shift button when switching between n, d, and 3, and the shift button must be hung from the 3rd down limit file, and the shift button is not required to go from the low gear to the high gear.

Must not be engaged in driving n-parade taxiing, because the need for lubrication in the automatic transmission, when the gear is placed on the n above when the pump can not be normal oil lubrication, the transmission will increase the temperature of the components, Causes total damage! In addition, the high speed is also very dangerous for empty taxiing, and it is not fuel efficient! There are many introductions in this area and I will not go into details. Slide to stop at low speed can be advanced into the n file, there is no effect.

The automatic transmission must not be pushed into the p-range while driving, unless you do not want the car to move from the reverse gear to the forward gear or the forward reverse gear when the direction of travel changes. Be sure to wait until the vehicle stops before operating. .

When the vehicle stops at the end of the journey, the automatic transmission must be turned off and hung in the p position to extract the key. Many people are accustomed to stopping and pushing directly to the p file to turn off the flames and pull the handbrake. Careful people will find this operation, after the flameout of the general vehicle due to uneven road will move a little before and after, and this time the p gear transmission has a bite device and the gear shift bite, then the shift will cause gear change A little impact! The correct approach should be: After the car enters the parking position, step on the brake to pull the shift lever to the n position. Pull up the handbrake, release the foot brake and turn off the flame, and then push the shift lever into the p position. Of course, this also belongs to the protection of gearboxes.

In addition, when it comes to temporary parking, there is always some controversy about whether the automatic transmission should use n-speed or d-speed. In fact, it does not matter. n or d is not wrong, but only according to their own habits, temporary parking brakes and hung on the d is no harm to the car, because the torque converter inside the transmission has a set of reaction wheels with a one-way clutch, its role is to enlarge The torque from the engine's crankshaft does not rotate when the engine is idling, and it only works when the engine speed increases. So slamming the brakes and other red lights also does not matter, hung to n pull hand brake is also no harm, the advantage is that you can let the right foot activity, take the time to relax and relax can apply a harder indicator: if the parking in more than half a minute You're stuck with n handbrake. If the parking time is short, just step on the brakes. It's worth noting that this is an explanation for the general automatic transmission. When your vehicle has special requirements, you can't In accordance with this, for example, Buick Sailou, it is clearly emphasized in its use of the CD, temporary parking can not be hung in the n file, because it has an automatic skip function, a few seconds after you press the brakes will automatically jump It was empty.
