大家都希望自己的變速箱保持良好的工作狀態(tài)，即使是壞了也希望能少一些維修費(fèi)。為了減少維修費(fèi)根本的辦法是要把握變速箱故障的前兆，這樣可以避免不必要的維修。那么自動(dòng)擋變速箱出問題之前的表現(xiàn)是怎樣的呢？下面濟(jì)南自動(dòng)變速箱維修人員為您解答。

We all hope that our gearbox can keep in good working condition, even if it is broken, we also hope that the maintenance fees can be reduced. The fundamental way to reduce maintenance costs is to grasp the precursors of gearbox failures, so that unnecessary maintenance can be avoided. What was the performance of the automatic transmission before it went wrong? Now Jinan automatic transmission maintenance personnel will answer for you.

1、變速箱故障燈提示、報(bào)警：這種情況一般為變速箱出現(xiàn)電控單元故障或機(jī)械單元故障。前者可能出現(xiàn)假性提示，假性提示只需對數(shù)據(jù)進(jìn)行處理，對變速箱硬件沒有傷害，費(fèi)用限于人工費(fèi)。故障燈提示有時(shí)也是偶發(fā)性的，有時(shí)會出現(xiàn)鎖擋，特別在加速途中出現(xiàn)鎖擋將導(dǎo)致車子失速，會有一定危險(xiǎn)性。因此遇到報(bào)警提示都需盡快到維修檢查。

1. Gearbox fault light prompt and alarm: This condition generally refers to the failure of electronic control unit or mechanical unit in the gearbox. The former may have false prompts, which only require professional processing of data, and will not harm the transmission hardware. The cost is limited to labor costs. The fault light prompt is also occasional, sometimes there will be a lock, especially when accelerating, which will lead to the car stalling, which will be dangerous. Therefore, in case of alarm prompt, it is necessary to go to the professional maintenance center for inspection as soon as possible.

2、打滑：踩油門，發(fā)動(dòng)機(jī)轉(zhuǎn)速升高，速度上不去。尤其是車子出地庫、爬高架時(shí)表現(xiàn)明顯。初期癥狀是偶發(fā)的。如果在駕駛習(xí)慣良好，車齡又不長的情況下，很多可能是變速箱油的問題導(dǎo)致的。這時(shí)候變速箱并沒有損壞，一般通過換油就能解決。還有一種可能就是離合器片、制動(dòng)器、活塞三者沒有匹配默契而導(dǎo)致打滑，這種情況就應(yīng)盡快找維修機(jī)構(gòu)檢查。

2. Slipping: When the accelerator is pressed, the engine speed will increase and the speed will not increase. Especially when the car is out of the basement and climbing overhead, it is obvious. Initial symptoms are sporadic. If the driving habits are good and the car is not old, many problems may be caused by the transmission oil. At this time, the gearbox is not damaged. It can be solved by changing the oil. Another possibility is that the clutch disc, brake and piston do not match with each other, resulting in slipping. In this case, you should find a professional maintenance organization to check as soon as possible.

3、頓挫：車子升降檔時(shí)有沖擊頓挫感，或在加速時(shí)有卡頓慫車的感覺。初期可能是因?yàn)殡姶砰y異常，不能對油壓正常調(diào)整，多數(shù)是油變質(zhì)了，閥道磨損致使電磁閥受損。初期只需更換電磁閥，價(jià)格不貴。若等到后期磨損更嚴(yán)重了，變速箱內(nèi)部的雜質(zhì)就會進(jìn)一步產(chǎn)生破壞力度，導(dǎo)致閥芯損傷，嚴(yán)重的話則需要更換閥體，維修費(fèi)就貴了。

3. Stuttering: The car feels bumpy when shifting up and down, or feels stuck when accelerating. At the initial stage, it may be that the solenoid valve is abnormal and the oil pressure cannot be adjusted normally. Most of the oil is deteriorated and the solenoid valve is damaged due to wear of the valve channel. At the initial stage, only the solenoid valve needs to be replaced, and the price is not expensive. If the wear becomes more serious in the later period, the impurities in the gearbox will further damage the valve core, causing serious damage. If it is serious, the valve body needs to be replaced, and the maintenance cost will be expensive.

4、換擋延遲；有些車換擋延遲是因?yàn)橛妥冑|(zhì)了導(dǎo)致油壓不足，很多情況下更換變速箱油即可解決問題。有的車則是因?yàn)樘焐脑O(shè)計(jì)缺陷，一般十萬公里后就容易出現(xiàn)該故障，主要原因在于機(jī)械部件如鋁鼓、波浪片磨損導(dǎo)致油壓不夠，該問題需及時(shí)檢查。

4. Shift delay; In some cars, the shift delay is caused by the insufficient oil pressure due to the deterioration of the oil. In many cases, the problem can be solved by changing the transmission oil. Some cars are born with design defects, which are easy to occur after 100000 km. The main reason is that the oil pressure is not enough due to the wear of mechanical parts such as aluminum drums and wave plates. This problem needs to be checked in time.

5、異響：車子開起來后出現(xiàn)非正常的響聲，可能原因一般是變速箱內(nèi)齒輪或軸承受力過大或自身材質(zhì)欠佳，也有可能是一些金屬部件接觸面不夠光滑導(dǎo)致，這種情況出現(xiàn)應(yīng)及時(shí)檢查維修，否則將擴(kuò)大損壞面積。

5. Abnormal noise: abnormal noise occurs after the car is driven, which may be caused by excessive bearing force of gears or bearings in the gearbox or poor material of the car itself, or it may be caused by the lack of smooth contact surface of some metal parts. In this case, timely inspection and maintenance should be carried out, otherwise the damaged area will be expanded.

6、變速箱出現(xiàn)高溫：通常在行駛過程中，儀表盤提示變速箱溫度過高，只要有提示則說明溫度已經(jīng)達(dá)到120度以上。一種情況是變速箱內(nèi)多組摩擦元件同時(shí)工作而導(dǎo)致高溫。這種情況須停車自然降溫，否則會快速損傷變速箱內(nèi)摩擦元件。另一種情況就是變速箱散熱器水管堵塞，無法散熱，這種情況則需要維修。

6. High temperature of the transmission: usually during driving, the instrument panel prompts that the transmission temperature is too high. If there is a prompt, it indicates that the temperature has reached more than 120 degrees. In one case, multiple groups of friction elements in the gearbox work at the same time, resulting in high temperature. In this case, the vehicle must be stopped to cool down naturally, otherwise the friction elements in the gearbox will be quickly damaged. The other case is that the radiator pipe of the transmission is blocked and cannot dissipate heat, which requires maintenance.

7、掛檔后發(fā)動(dòng)機(jī)熄火：變矩器內(nèi)單向離合器卡死，起不到單向增扭作用。這種情況一般是偶發(fā)，但需盡快到維修機(jī)構(gòu)排查處理。

7. Engine stalling after gear is engaged: the one-way clutch in the torque converter is stuck, which cannot play a one-way torque increasing role. This situation usually happens occasionally, but it needs to be checked and handled by a professional maintenance organization as soon as possible.

以上我們總結(jié)了七種問題，任何一種問題在置之不理的情況下都有可能發(fā)展成多種問題。多種問題的維修費(fèi)自然就被拉高了。所以說變速箱出現(xiàn)故障前兆要把握佳時(shí)機(jī)進(jìn)行處理，有的可能通過換油就能變好，有的則需要有維修機(jī)構(gòu)來處理。更多相關(guān)內(nèi)容就來我們網(wǎng)站http://njzhuiri.cn咨詢了解吧！
