　　Listening to the customer's fault description is the beginning of the entire diagnosis and a very important step. When listening to the fault description, attention should be paid to the following: try to understand the accurate phenomenon of the fault as much as possible. Because many customers find it difficult to accurately describe the specific condition of the fault, try to use sensory terms and avoid using too many professional vocabulary. Try to clarify the specific conditions under which the fault occurred, such as temperature, speed, engine speed, whether there was any abnormal noise, whether it occurred frequently or sporadically. It is very important to register the repair history of the vehicle, including the time, items, and replacement parts of the previous maintenance. Register other requirements of the customer, such as the standard of repair, how long it takes, and other related items

　　檢驗(yàn)油品

　　Inspect oil products

　　檢查油品對(duì)于準(zhǔn)確診斷變速箱的故障非常有幫助，非常類(lèi)似醫(yī)院的化驗(yàn)血,變速箱油品從顏色上分為紅色和黃色兩種，其中后者是免維護(hù)變速箱使用的油品，正常的油品應(yīng)該鮮紅（或者明亮的黃色）、明亮、干凈、無(wú)雜質(zhì)、無(wú)刺激氣味。  如果油品黑色污濁說(shuō)明變速箱內(nèi)部的摩擦材料已經(jīng)燒損，需要解體徹底維修如果油品出現(xiàn)粉色粘稠乳狀說(shuō)明變速箱內(nèi)部已經(jīng)進(jìn)水，初期可以通過(guò)更換油品2－3次的辦法來(lái)解決，如果已經(jīng)超過(guò)30天或者行駛300公里以上，則必須通過(guò)大修來(lái)解決這個(gè)問(wèn)題，變速箱是封閉的箱體，能夠進(jìn)水的地方有兩個(gè)，最常規(guī)的是散熱系統(tǒng)的水箱內(nèi)部腐蝕造成油水混合，還有一個(gè)是通過(guò)透氣孔進(jìn)水，一般變速箱的透氣孔設(shè)計(jì)的都比較高，所以除非車(chē)輛涉水否則一般不會(huì)出現(xiàn)此種情況   如果油品出現(xiàn)灰色伴有煙霧和刺激氣味，說(shuō)明變速箱內(nèi)部已經(jīng)嚴(yán)重高溫，嚴(yán)重的時(shí)候行星齒輪等部件都可能已經(jīng)燒毀，此種情況需要立即大修。

　　Checking the oil is very helpful for accurately diagnosing transmission faults, similar to the blood test in hospitals. Transmission oil is divided into two colors: red and yellow, with the latter being the oil used for maintenance free transmissions. Normal oil should be bright red (or bright yellow), bright, clean, free of impurities, and have no irritating odor. If the oil is black and dirty, it indicates that the friction material inside the gearbox has been burned and needs to be disassembled for thorough repair. If the oil appears as a pink viscous emulsion, it indicates that water has entered the gearbox. In the initial stage, this can be solved by replacing the oil 2-3 times. If it has been more than 30 days or driven for more than 300 kilometers, it must be solved through major repairs. The gearbox is a closed box, and there are two places where water can enter. The most common is the corrosion inside the radiator of the cooling system, causing oil-water mixture. Another place is through the ventilation hole. Generally, the ventilation hole design of the gearbox is relatively high, so unless the vehicle is submerged in water, this situation usually does not occur. If the oil appears gray with smoke and irritating odor, it indicates that the gearbox is severely hot inside, In severe cases, components such as planetary gears may have been burned out, and this situation requires immediate major repairs.

　　檢查底盤(pán)等相關(guān)連接件

　　Check the chassis and other related connectors

　　雖然電子診斷儀器非常先進(jìn)，但也有他的局限性，底盤(pán)等一些機(jī)械的部件的性能對(duì)于變速箱的影響也是非常大的檢查底盤(pán)包括底盤(pán)異響、減震橡膠件、連接螺絲、底盤(pán)漏油、散熱系統(tǒng)的性能等很多方面，這一部分工作需要做的細(xì)致徹底。

　　Although electronic diagnostic instruments are very advanced, they also have their limitations. The performance of mechanical components such as the chassis also has a significant impact on the transmission. Checking the chassis includes many aspects such as chassis noise, shock absorber rubber parts, connecting screws, chassis oil leakage, and the performance of the cooling system. This part of the work needs to be done carefully and thoroughly.

　　診斷－路試

　　Diagnosis - Road Test

　　故障，盡可能需要的其他相關(guān)伴隨的 路試是進(jìn)一步確定顧客所投訴的故障現(xiàn)象必不可少的程序，路試的技師需要非常專(zhuān)業(yè)的訓(xùn)練路試需要路試的內(nèi)容包括引擎的動(dòng)力、引擎運(yùn)轉(zhuǎn)平穩(wěn)行、變速箱的入檔感受、動(dòng)力輸出、換檔的時(shí)機(jī)的早晚、換檔的平順性、變鈕器鎖止的結(jié)合程度、變速箱的異響、底盤(pán)的 性能等方面路試需要刻意模擬客戶所投訴的從現(xiàn)故障，并詳細(xì)了解出現(xiàn)故障條件。

　　Malfunctions and other related accompanying road tests are essential procedures for further determining the symptoms of customer complaints. Road test technicians require very professional training. The content of road tests includes engine power, smooth engine operation, gearbox shifting sensation, power output, timing of gear shifts, smoothness of gear shifts, degree of engagement of knob locks, abnormal gearbox noise, chassis performance, etc. Road tests need to deliberately simulate the current faults complained by customers and have a detailed understanding of the conditions under which the faults occurred.

　　電子掃描讀取故障記錄

　　Electronic scanning reads fault records

　　現(xiàn)在的自動(dòng)變速箱廣泛的采用智能化設(shè)計(jì)，電子控制程度很高，不僅可以根據(jù)駕駛者的需求和車(chē)輛的情況進(jìn)行控制，并且具有非常強(qiáng)的自診斷功能，借助專(zhuān)用的電子診斷儀器就可以得到隨車(chē)的實(shí)際運(yùn)行數(shù)據(jù)。  專(zhuān)業(yè)的維修技師通過(guò)對(duì)以上數(shù)據(jù)的分析和判斷就可以快速的確定問(wèn)題所在，不僅提高了效率，而且準(zhǔn)確率也高了很多。

　　Nowadays, automatic transmissions widely adopt intelligent design and have a high degree of electronic control. They can not only be controlled according to the driver's needs and the vehicle's situation, but also have strong self diagnostic functions. With the help of specialized electronic diagnostic instruments, actual operating data of the vehicle can be obtained. Professional maintenance technicians can quickly identify the problem by analyzing and judging the above data, which not only improves efficiency but also significantly increases accuracy.
