济南车主注意，自动挡一“D”到底，变速箱寿命直接折半

　　Attention Jinan car owners, if the automatic transmission is fully engaged, the lifespan of the gearbox will be halved

　　对济南绝大多数自动挡车主而言，“点火挂D挡、熄火摘D挡”似乎是默认操作，不少车主甚至认为，自动挡的核心优势就是“不用换挡”，一“D”到底既省心又省事。但资深汽车维修从业者提醒，这种看似便捷的操作，正在悄悄损耗你的变速箱——据济南本地汽车维修数据显示，70%以上的自动变速箱提前损坏，都与长期一“D”到底的操作习惯有关，严重时可使变速箱寿命折半，维修成本高达5000-20000元，给济南车主带来不必要的损失。今天就结合济南城市通勤场景，拆解自动挡正确操作技巧，避开误区、保护变速箱，还能省油降耗。

　　For the vast majority of automatic transmission car owners in Jinan, "ignition in D gear, engine off to D gear" seems to be the default operation. Many car owners even believe that the core advantage of automatic transmission is "no need to shift gears", and a "D" is both worry free and effortless. However, senior automotive maintenance practitioners remind that this seemingly convenient operation is quietly damaging your gearbox - according to local automotive maintenance data in Jinan, more than 70% of automatic transmissions are damaged prematurely, which is related to long-term "D" operation habits. In severe cases, it can halve the lifespan of the gearbox, with maintenance costs as high as 5000-20000 yuan, causing unnecessary losses to Jinan car owners. Today, combined with the commuting scene in Jinan city, we will dismantle the correct operation skills of automatic transmission, avoid misunderstandings, protect the gearbox, and save fuel and consumption.

　　首先明确核心认知：自动挡不是“全自动”，更不能一“D”到底。自动挡的P、R、N、D、S挡，每一个挡位都有其专属用途，适配不同路况，盲目长期挂D挡，不仅会加剧变速箱磨损，还会增加油耗、缩短零部件寿命。尤其济南早晚高峰拥堵严重、坡路较多（如英雄山路、经十东路部分路段），错误的挡位操作，对变速箱的损伤会更明显。

　　Firstly, clarify the core understanding: automatic transmission is not "fully automatic", let alone "D" all the way through. The P, R, N, D, and S gears of automatic transmission have their own exclusive uses, adapting to different road conditions. Blindly shifting to D gear for a long time will not only exacerbate transmission wear, but also increase fuel consumption and shorten component life. Especially in Jinan, there is severe congestion during peak hours in the morning and evening, and there are many sloping roads (such as Hero Mountain Road and some sections of Jing Shi Dong Road). Incorrect gear operation can cause more obvious damage to the gearbox.

　　最常见的误区就是等红灯时长期挂D挡。很多济南车主等红灯时，习惯一直挂D挡、踩刹车停车，殊不知这会带来两大危害：一是频繁踩刹车会加剧刹车片摩擦，使其使用寿命缩短30%以上；二是长时间挂D挡会让变速箱处于负荷状态，温度大幅升高，容易导致变速箱油液变质，进而加剧内部齿轮磨损，若遭遇追尾事故，还可能造成变速箱严重损坏。正确做法是：等红灯超过2分钟，立即拉手刹、挂入N挡，既能保护变速箱，也能减少刹车片损耗。

　　The most common misconception is to shift into D gear for a long time while waiting for a red light. Many car owners in Jinan, when waiting at red lights, are accustomed to constantly shifting to D gear and braking to stop, unaware of the two major hazards that this can bring: firstly, frequent braking can exacerbate brake pad friction, reducing its service life by more than 30%; Secondly, prolonged engagement in D gear can put the gearbox under load, causing a significant increase in temperature, which can easily lead to the deterioration of the gearbox oil and exacerbate internal gear wear. In the event of a rear end collision, it may also cause serious damage to the gearbox. The correct approach is to wait for the red light to exceed 2 minutes, immediately apply the handbrake and shift into N gear, which can protect the gearbox and reduce brake pad wear.

　　济南多坡路段较多，爬坡时一“D”到底同样不可取。不少车主爬坡时仍挂D挡，导致车辆动力不足、变速箱频繁换挡，加剧磨损。其实，S挡（运动模式）就是爬坡、超车的“神器”，从D挡向下轻拨即可切换，切换后变速箱可自由换挡、无需等待，能提供更强的动力输出，轻松应对爬坡路段。但需注意，S挡不能长期使用，否则会使油耗升高15%-20%，仅在爬坡、高速超车时使用即可。

　　There are many sloping sections in Jinan, so it is also not advisable to use a "D" when climbing. Many car owners still shift into D gear when climbing hills, resulting in insufficient power and frequent gearbox changes, exacerbating wear and tear. In fact, S gear (sport mode) is the "magic weapon" for climbing and overtaking. Simply shift down from D gear to switch. After switching, the gearbox can shift freely without waiting, providing stronger power output and easily handling uphill sections. However, it should be noted that S gear cannot be used for a long time, otherwise it will increase fuel consumption by 15% -20%. It can only be used when climbing slopes or overtaking at high speeds.

　　早晚高峰拥堵路段，也是变速箱损伤的“重灾区”。济南早晚高峰（7:00-9:00、17:00-19:00），车辆走走停停，若始终挂D挡，会持续增加变速箱负荷，不仅油耗升高，还会加速变速箱内部零件磨损。正确操作是：拥堵路段频繁停车时，及时切换至N挡，减少变速箱负荷，同时降低油耗，长期坚持可使百公里油耗降低0.5-1L。

　　The congested sections during morning and evening rush hours are also the "hardest hit areas" for gearbox damage. During the morning and evening rush hour in Jinan (7:00-9:00, 17:00-19:00), vehicles start and stop. If the D gear is always engaged, it will continue to increase the load on the gearbox, not only increasing fuel consumption but also accelerating the wear of internal parts of the gearbox. The correct operation is: when parking frequently on congested roads, switch to N gear in a timely manner to reduce transmission load and fuel consumption. Long term persistence can reduce fuel consumption by 0.5-1L per 100 kilometers.

　　此外，巧用AUTOHOLD自动驻车功能，既能保护变速箱，也能提升驾驶便捷性。济南车主可根据场景灵活使用：30秒以内的临时停车、坡道起步时，开启AUTOHOLD，无需拉手刹、无需切换D/N挡，车子可稳稳停住，避免溜车；但严重拥堵时，建议关闭AUTOHOLD，避免变速箱频繁处于负荷状态，进一步保护变速箱。

　　In addition, cleverly using the AUTOHOLD automatic parking function can not only protect the gearbox, but also improve driving convenience. Jinan car owners can flexibly use it according to the scene: for temporary parking within 30 seconds or starting from a slope, AUTOHOLD can be activated without pulling the handbrake or switching to D/N gear. The car can come to a stable stop and avoid slipping; But when there is severe congestion, it is recommended to turn off AUTOHOLD to avoid the gearbox being frequently under load and further protect the gearbox.

　　值得注意的是，长期错误操作不仅损伤变速箱，还会导致发动机积炭、零部件磨损加剧。济南车主若长期低速拥堵行驶，未充分燃烧的油垢会附着在节气门、进气系统等处，影响发动机运作，进而间接影响变速箱性能。掌握正确的自动挡操作技巧，不仅能延长变速箱寿命（可延长50%以上），还能降低维修成本、节省油耗，贴合济南车主的日常通勤需求。希望各位济南车主摒弃“一D到底”的坏习惯，正确使用各挡位，让车辆更耐用、出行更省心。

　　It is worth noting that long-term incorrect operation not only damages the gearbox, but also leads to engine carbon buildup and increased wear of components. If car owners in Jinan drive at low speeds and congestion for a long time, unburned oil stains will adhere to the throttle valve, intake system, etc., affecting engine operation and indirectly affecting transmission performance. Mastering the correct automatic transmission operation skills can not only extend the life of the gearbox (by more than 50%), but also reduce maintenance costs, save fuel consumption, and meet the daily commuting needs of Jinan car owners. I hope all Jinan car owners will abandon the bad habit of "one D to the end" and use each gear correctly, making the vehicle more durable and travel more worry free.
