現象：變速箱漏油汽車多少都會有一些癥狀表現出來，如果變速箱漏油量大的話，你就會發(fā)現車子起步費力，低檔位沖擊感嚴重，車跑的時候踩下油門轉速提升，車子不怎么動，感覺象沒掛上擋一樣，這就是變速箱漏油的癥狀。
Phenomenon: if the transmission oil leaks, the car will show some symptoms. If the transmission oil leaks a lot, you will find that the car starts laboriously and has a serious impact at low gear. When the car runs, step on the accelerator and the speed increases. The car doesn't move much. It feels like it's not in gear. This is the symptom of transmission oil leakage.
漏油原因：實際工作時箱內溫度很高，使箱內潤滑油產生蒸氣，充滿箱體空間，導致箱內壓力升高，往往在更薄弱處，油氣沖出而產生泄漏。多數都是由于變速箱油溫過高、裝配工藝或變速箱油封質量這些問題所導致的漏油。
Cause of oil leakage: during actual operation, the temperature in the box is very high, which causes the lubricating oil in the box to produce steam and fill the box space, resulting in the increase of pressure in the box. Often at the weakest place, oil and gas rush out and leak. Most of the oil leakage is caused by the problems of high transmission oil temperature, assembly process or transmission oil seal quality.
漏油后果：變速箱油和機油的作用一樣，主要起潤滑、清潔、降溫、防銹、密封的作用，因此變速箱油缺少了就會造成變速箱內部潤滑不夠，造成干磨，長時間干磨就會報廢。
Consequences of oil leakage: transmission oil plays the same role as engine oil in lubrication, cleaning, cooling, rust prevention and sealing. Therefore, the lack of transmission oil will lead to insufficient lubrication inside the transmission, resulting in dry grinding, and the long-term dry grinding will be scrapped.
掛擋后發(fā)動機熄火
The engine stalls when the gear is engaged
現象：發(fā)動機怠速運轉時將操縱手柄由P位或N位換入R位、D位、S位、L位（或2位、1位）時發(fā)動機熄火?；蚴窃谇斑M擋或倒擋行駛中，踩下制動踏板停車時發(fā)動機熄火。
Phenomenon: when the engine is idling, change the joystick from position P or n to position R, D, s and l (or position 2 and 1), and the engine will shut down. Or when driving in forward gear or reverse gear, press the brake pedal to stop the engine.
故障原因：可能是以下四個原因：發(fā)動機怠速過低；閥板中的鎖止控制閥卡滯；擋位開關有故障；輸入軸轉速傳感器有故障。
Fault cause: there may be four reasons as follows: the engine idle speed is too low; The locking control valve in the valve plate is stuck; The gear switch is faulty; The input shaft speed sensor is faulty.
危害：如果數次掛擋造成發(fā)動機熄火，這時要查看入擋沖擊是不是很大，如果比較大，就要打救援電話。不然多次嘗試，本來只是換個閥體的事，卻變成了變速箱大修。
Harm: if the engine stalls due to several gears, check whether the gear in impact is great. If it is large, call the rescue phone. Otherwise, many attempts, originally just to change the valve body, turned into a gearbox overhaul.
變速箱鎖擋
Transmission lock
現象：汽車在正常行駛中，加油只見轉速很高，但是速度卻提得很慢，踩剎車速度降到一定程度不降了。
Phenomenon: when the car is running normally, when refueling, the speed is very high, but the speed is very slow. When stepping on the brake, the speed does not drop to a certain extent.
故障原因：自動變速箱的輸入輸出信號不正確或者各元件本身路線不良導致，有時也會有自動變速箱電腦和其他系統(tǒng)電腦的通信有問題而產生。
Fault cause: the input and output signals of the automatic transmission are incorrect or the routes of various components are poor. Sometimes, there are problems in the communication between the automatic transmission computer and other system computers.
危害：行駛的過程中很容易將自己處置在危險的環(huán)境中，在市區(qū)行駛速度降不下來或者走高速升不上去很容易出現事故。
Harm: it is easy to dispose of yourself in a dangerous environment during driving. It is easy to have accidents if the driving speed in the urban area cannot be reduced or the driving speed cannot be increased at high speed.
入擋后汽車不動
The car does not move when in gear
現象：在汽車啟動后將擋位掛D或者R擋后，松開剎車后車輛沒有任何反應，不向前行使。手動掛1擋，松開離合后，汽車不行駛。
Phenomenon: after starting the car, shift the gear to D or R and release the brake, the car will not react and will not move forward. Manually shift to the first gear. After releasing the clutch, the car will not run.
故障原因：可能是變速箱輸入軸或者倒擋離合器出現損壞，或者D/R制動器損壞造成。也可能是變速箱漏油，嚴重缺少變速箱油導致，或者是汽車換擋桿和手動閥搖臂之間的連桿或拉索松脫，導致手動閥保持在或停車擋位置。
Fault cause: it may be caused by damage to transmission input shaft or reverse clutch, or damage to D / R brake. It may also be caused by oil leakage from the transmission, a serious lack of transmission oil, or the connecting rod or cable between the vehicle shift lever and the rocker arm of the manual valve is loose, resulting in the manual valve remaining in the or parking position.
危害：容易使車主出現暴躁情緒，這時候必須要冷靜，多嘗試幾次后，汽車仍然不動，在撥打救援電話。
Harm: it is easy to make the owner irritable. At this time, you must be calm. After trying several times, the car still doesn't move and dialing the rescue call.
換擋沖擊
shift shock
現象：自動變速箱換擋沖擊是指車輛在起步中由停車擋或空擋掛入倒擋或前進擋時，汽車振動較嚴重，或是在行駛中，自動變速箱在某個擋位或全部擋位升擋的瞬間，汽車有著較明顯的沖擊。
Phenomenon: shift impact of automatic transmission refers to that when the vehicle shifts from parking gear or neutral gear to reverse gear or forward gear during starting, the vehicle vibrates seriously, or the vehicle has obvious impact at the moment when the automatic transmission rises in a gear or all gears during driving.
故障原因：原因可能有以下幾種：更常見的原因是變速箱油到了需要更換的階段；其他原因還包括發(fā)動機怠速過高 ；節(jié)氣門拉索或節(jié)氣門位置傳感器調整不當；升擋過遲；主調壓閥故障；換擋執(zhí)行元件打滑；油壓電磁閥不工作；電腦故障。
Cause of failure: there may be the following reasons: the most common reason is that the transmission oil needs to be replaced; Other reasons include high engine idle speed; Improper adjustment of throttle cable or throttle position sensor; Gear up too late; Failure of main pressure regulating valve; Shift actuator slipping; The oil pressure solenoid valve does not work; Computer failure.
解決方式：更換變速箱油，并對變速箱進行診斷。
Solution: replace the transmission oil and diagnose the transmission.
