變速箱作為汽車重要的三大件之一，由于其結(jié)構(gòu)的復(fù)雜性、精密性以及高昂的造價，一旦出現(xiàn)故障，維修費(fèi)用十分昂貴。為了防止變速箱大修花大錢，我們可以怎么做呢？

　　As one of the three important components of a car, the gearbox has a complex structure, precision, and high cost. Once a malfunction occurs, the maintenance cost is very expensive. What can we do to prevent the gearbox from spending a lot of money on major repairs?

　　其實(shí)變速箱出故障是會有一些前兆提示的，這時候掌握一定的變速箱故障診斷方法就顯得尤為重要，接下來給大家介紹變速箱出故障的五個征兆。

　　In fact, there are some warning signs of gearbox failure, and it is particularly important to master certain diagnostic methods for gearbox faults. Next, we will introduce five signs of gearbox failure.

　　01加速無力、發(fā)動機(jī)空轉(zhuǎn)

　　01 Weak acceleration and engine idling

　　汽車起步慢，在加速或者爬坡的時候明顯感覺加速無力，轉(zhuǎn)速表飆升，時速表不動，甚至可以聽見發(fā)動機(jī)空轉(zhuǎn)的聲音。

　　The car starts slowly, and when accelerating or climbing hills, there is a noticeable feeling of weak acceleration, with the tachometer soaring and the speedometer not moving, and even the sound of the engine idling can be heard.

　　這種情況很可能就是變速箱內(nèi)部打滑，此時變速箱內(nèi)的離合器片、制動片、制動帶出現(xiàn)磨損燒蝕，或是變速箱內(nèi)的油壓過低。如果出現(xiàn)這種情況，一定要盡快到店維修。

　　This situation is likely due to internal slippage of the gearbox, where the clutch plates, brake pads, and brake belts inside the gearbox are worn and eroded, or the oil pressure inside the gearbox is too low. If this situation occurs, be sure to go to the store for repair as soon as possible.

　　02換擋不順、擋桿震手、頓挫

　　02 Difficulty shifting gears, shaking gear lever, jerking

　　行駛過程中感覺換檔不順，擋桿有震動，變速箱在加速的過程中產(chǎn)生比較強(qiáng)烈的沖擊、頓挫感。

　　During the driving process, I feel that the gear shift is not smooth, the gear lever vibrates, and the gearbox produces a strong impact and jerking sensation during acceleration.

　　這種情況一般是由于沒有定期換油，變速箱內(nèi)油泥、雜質(zhì)太多了，堵塞了閥體，無法較好地對油壓進(jìn)行調(diào)節(jié)，導(dǎo)致變速箱產(chǎn)生頓挫。這種情況更換變速箱油一般就能解決。

　　This situation is generally due to the lack of regular oil changes, excessive sludge and impurities in the gearbox, which clogs the valve body and makes it difficult to regulate the oil pressure, resulting in jerking in the gearbox. This situation can usually be solved by replacing the transmission oil.

　　03變速箱異響

　　03 Transmission abnormal noise

　　汽車在怠速或者行駛的過程中時常出現(xiàn)莫名其妙的響聲，甚至是分貝很大的噪音，在擋位切換的過程中時不時會出現(xiàn)比較沉悶的響聲。

　　During idling or driving, cars often make inexplicable noises, even very loud ones, and there may be dull noises during gear shifting.

　　一般是因?yàn)樽兯傧鋬?nèi)齒輪或軸承受力過大或材質(zhì)缺陷導(dǎo)致，一旦我們察覺有異響就應(yīng)及時檢查維修，不然將會導(dǎo)致更多機(jī)械部位損傷。

　　Generally, it is caused by excessive force or material defects on the gears or shafts inside the gearbox. Once we detect any abnormal noise, we should promptly inspect and repair it, otherwise it will lead to more mechanical damage.

　　04變速箱高溫

　　04 Transmission high temperature

　　通常儀表會提示變速箱溫度過高，提示的溫度都在120度以上。一種可能是變速箱內(nèi)摩擦元件高強(qiáng)度工作導(dǎo)致高溫，這時應(yīng)停車自然降溫。

　　Usually, the instrument panel will indicate that the transmission temperature is too high, and the indicated temperature is above 120 degrees Celsius. One possibility is that the high-intensity operation of the friction elements inside the gearbox causes high temperatures, and in this case, the vehicle should be stopped to naturally cool down.

　　還有一種可能因?yàn)樽兯傧渖崞魉芏氯?，?dǎo)致油溫升高，這就需要及時維修。

　　There is also a possibility that the blockage of the transmission radiator water pipe may cause the oil temperature to rise, which requires timely maintenance.

　　05變速箱鎖檔，無法換擋

　　05 gearbox locked, unable to shift gears

　　行駛的過程中，變速箱排擋桿鎖在某個擋位無法進(jìn)行換擋。這種情況一般是因?yàn)樽兯傧涞妮斎胼敵鲂盘柍鲥e了或者是因?yàn)楦髟肪€不良導(dǎo)致。

　　During driving, the transmission gear lever is locked in a certain gear and cannot be shifted. This situation is usually caused by errors in the input and output signals of the gearbox or poor wiring of various components.

　　變速箱一旦在行駛中出現(xiàn)鎖檔的狀況是非常危險，一旦發(fā)現(xiàn)，必須馬上去修理廠或者4S店進(jìn)行檢修！

　　Once the gearbox is locked while driving, it is very dangerous. Once discovered, it must be immediately repaired at a repair shop or 4S dealership!
