In recent years, with the overall improvement of social consumption power, the car consumer group has gradually tended to be younger, which also means that the number of white drivers has gradually increased, especially female drivers. Driven by such an environment, the automatic transmission models with "fool-like" operation and not easy to turn off are naturally loved by the whites, especially in the stop-and-go urban driving environment, and have become the mainstream models in the city.
But it is precisely because this car is "easy to drive" that many consumers forget or ignore their driving habits and related maintenance, resulting in how long they do not "enjoy" a small problem and "always have something to do", so what is a good driving habit? Or how can you make yourself "idle"? Xiaobian sorted out some of the most harmful automatic transmission model gearbox behaviors, for the little white to learn to fill in the gaps.
Novice drivers who coast in N gear (neutral) often have such a misunderstanding when they first start driving, that is, coasting in neutral will save fuel, on the grounds that the engine stops rotating and does not consume gasoline, is that so?
The answer is yes, gasoline can be saved, but the greater loss is overlooked, that is, the damage to the gearbox. From the principle of the automobile, the automatic transmission model is prone to insufficient oil pressure in the hydraulic pipeline of the gearbox due to the difference between the speed and the engine speed when coasting in neutral gear, which will increase the mechanical friction, damage the friction plate inside the gearbox, and eventually lead to transmission failure. So don't do the thing of "losing the watermelon and picking sesame seeds".
Parking for a long time is still in D gear (driving gear)
Driving traffic jams in the city is a common thing, especially in the morning and evening rush hours, many car owners in traffic jams, the habitual operation is to only step on the brake pedal, but the gear lever is still in D gear. This is allowed if the time is short. However, if the parking time is long, although the brake pedal is pressed, the power of the engine is still transmitted to the gearbox, which will cause the transmission oil temperature to rise and the oil deteriorate, which will lead to car failure. So the best thing to do is to stop and wait for a long time, shift into N gear and tighten the parking brake.
The car shifts into R gear (reverse) without fully coming to a standstill.
This is mainly for the car owner who is more anxious, or a novice friend who has just started driving, the car is not completely stopped and then shifted into the R gear, which will wear out the clutch plate in the gearbox, because of the inertia of the movement, forcing the car to produce "reverse rotation pressure", just like a child is not in a hurry to learn to run, the forward, stop, and backward three actions are "combined into two", which naturally causes excessive wear and tear of the clutch plate after many years, resulting in gearbox failure.
Do not change the transmission oil for a long time
This is about the maintenance of many people often do not pay attention to the place, especially the white or not pay attention to the maintenance of the car owners, on the one hand, do not know to change the transmission oil, on the other hand, know to change the oil, but not how often to change. If the transmission oil is not changed for a long time, there will be a weak start in the cold car, and it is easy to slip slightly when driving. This is because if the transmission oil is not changed for a long time, the transmission oil will become thicker, which is easy to block the transmission radiator and lead to related failures. According to the introduction of professional masters, it is usually more reasonable to replace the transmission oil every 5-80,000 kilometers.
Xiaobian summary: Although the operation of automatic transmission vehicles is simple, some bad driving habits or some misoperation are also easy to damage the gearbox, so when we drive automatic transmission vehicles to change gears, especially novice drivers must stop the vehicle and then switch gears to ensure the service life of the automatic transmission.
