濟南車主注意，自動擋一“D”到底，變速箱壽命直接折半

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

　　對濟南絕大多數(shù)自動擋車主而言，“點火掛D擋、熄火摘D擋”似乎是默認操作，不少車主甚至認為，自動擋的核心優(yōu)勢就是“不用換擋”，一“D”到底既省心又省事。但資深汽車維修從業(yè)者提醒，這種看似便捷的操作，正在悄悄損耗你的變速箱——據(jù)濟南本地汽車維修數(shù)據(jù)顯示，70%以上的自動變速箱提前損壞，都與長期一“D”到底的操作習慣有關，嚴重時可使變速箱壽命折半，維修成本高達5000-20000元，給濟南車主帶來不必要的損失。今天就結合濟南城市通勤場景，拆解自動擋正確操作技巧，避開誤區(qū)、保護變速箱，還能省油降耗。

　　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.

　　首先明確核心認知：自動擋不是“全自動”，更不能一“D”到底。自動擋的P、R、N、D、S擋，每一個擋位都有其專屬用途，適配不同路況，盲目長期掛D擋，不僅會加劇變速箱磨損，還會增加油耗、縮短零部件壽命。尤其濟南早晚高峰擁堵嚴重、坡路較多（如英雄山路、經(jīng)十東路部分路段），錯誤的擋位操作，對變速箱的損傷會更明顯。

　　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.

　　非常常見的誤區(qū)就是等紅燈時長期掛D擋。很多濟南車主等紅燈時，習慣一直掛D擋、踩剎車停車，殊不知這會帶來兩大危害：一是頻繁踩剎車會加劇剎車片摩擦，使其使用壽命縮短30%以上；二是長時間掛D擋會讓變速箱處于負荷狀態(tài)，溫度大幅升高，容易導致變速箱油液變質，進而加劇內部齒輪磨損，若遭遇追尾事故，還可能造成變速箱嚴重損壞。正確做法是：等紅燈超過2分鐘，立即拉手剎、掛入N擋，既能保護變速箱，也能減少剎車片損耗。

　　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.

　　濟南多坡路段較多，爬坡時一“D”到底同樣不可取。不少車主爬坡時仍掛D擋，導致車輛動力不足、變速箱頻繁換擋，加劇磨損。其實，S擋（運動模式）就是爬坡、超車的“神器”，從D擋向下輕撥即可切換，切換后變速箱可自由換擋、無需等待，能提供更強的動力輸出，輕松應對爬坡路段。但需注意，S擋不能長期使用，否則會使油耗升高15%-20%，僅在爬坡、高速超車時使用即可。

　　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.

　　早晚高峰擁堵路段，也是變速箱損傷的“重災區(qū)”。濟南早晚高峰（7:00-9:00、17:00-19:00），車輛走走停停，若始終掛D擋，會持續(xù)增加變速箱負荷，不僅油耗升高，還會加速變速箱內部零件磨損。正確操作是：擁堵路段頻繁停車時，及時切換至N擋，減少變速箱負荷，同時降低油耗，長期堅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自動駐車功能，既能保護變速箱，也能提升駕駛便捷性。濟南車主可根據(jù)場景靈活使用：30秒以內的臨時停車、坡道起步時，開啟AUTOHOLD，無需拉手剎、無需切換D/N擋，車子可穩(wěn)穩(wěn)停住，避免溜車；但嚴重擁堵時，建議關閉AUTOHOLD，避免變速箱頻繁處于負荷狀態(tài)，進一步保護變速箱。

　　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，長期錯誤操作不僅損傷變速箱，還會導致發(fā)動機積炭、零部件磨損加劇。濟南車主若長期低速擁堵行駛，未充分燃燒的油垢會附著在節(jié)氣門、進氣系統(tǒng)等處，影響發(fā)動機運作，進而間接影響變速箱性能。掌握正確的自動擋操作技巧，不僅能延長變速箱壽命（可延長50%以上），還能降低維修成本、節(jié)省油耗，貼合濟南車主的日常通勤需求。希望各位濟南車主摒棄“一D到底”的壞習慣，正確使用各擋位，讓車輛更耐用、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.
