關于變速箱的重要性，相信很多車主都明白，不需要再去論述。變速箱不容易出現問題，但是如果一旦出現故障，就比較麻煩。當變速箱故障發生時該怎么辦呢，別著急，接下來我們就為大家介紹變速箱故障診斷分析，解決各位車主的后顧之憂。
As for the importance of gearboxes, I believe many owners understand that there is no need to discuss them again. Gearboxes are not prone to problems, but if they fail, they will be more troublesome. When the gearbox failure should be done, do not worry, then we will introduce the gearbox fault diagnosis analysis for you, to solve the worries of the owners of the car.
變速箱故障診斷分析
Fault diagnosis and analysis of gearbox
1、掛檔難、頓挫感
1. It is difficult to file a file and a feeling of frustration
起步或行駛過程中，掛、摘、換擋發澀、費力，好像被什么卡了一下，有聳車、震動、頓挫感，有時涼車易掛擋，熱車難掛擋，帶有很多不舒適性;原因是變速箱內相關齒輪等部件得不到足夠的潤滑，且形不成持久的潤滑膜，使得部件無法流暢工作。
In the process of starting or driving, hanging, picking and shifting are astringent and laborious. It seems to be stuck with something, such as shrug, vibration, and setback, sometimes the cool car is easy to hang up, the hot car is difficult to hang up, and it has a lot of discomfort. The reason is that the gear and other parts in the gearbox cannot be lubricated enough, and the shape is not a durable lubricating film. The parts do not work smoothly.
2、自動擋闖擋、沖擊感
2, automatic blocking, impact feeling
起步沒動力，低速或中速行駛時車子有明顯聳車和頓挫感，同時儀表盤上的轉速表針上下浮動;中高速行駛過程中急踩油門踏板的情況下，車子打滑，轉速表針急速上升和有明顯的沖擊感;由P檔掛入R檔和D檔，車子有明顯的沖擊感、闖檔。
The car has obvious shrug and frustration at low speed or medium speed, while the speed surface on the dashboard is floating up and down; in the middle and high speed process, the car skid, the speed needle rises rapidly and has a significant impact; the car has an obvious impact on the R and D gear from the P gear. To break the file.

原因可能是變速箱內出現雜質，在閥體形成堵塞，導致閥體上下運動不暢，無法順序實現對油壓的調節，導致闖擋、換擋沖擊故障。
The cause may be the appearance of impurities in the gearbox, forming a blockage in the valve body, causing the valve body to move down and down, and can not adjust the oil pressure in order, leading to the break and shift impact failure.
3、變速箱異響、噪音大
3. Abnormal noise and loud noise of gearbox
車子在怠速時或行駛以及高負荷行駛過程中，聽到變速器有異響，甚至很大的噪音，在掛換擋時有無節奏、沉悶的響聲。造成上述現象的主要原因是變速箱內臟污，軸承、齒輪等部件出現磨損或嚴重磨損，或齒輪側面有損壞。
When the car is in the process of idle speed or driving and high load, it is heard that the transmission has different noise, even a lot of noise, and there is no rhythm and dreary noise in the gear shift. The main causes of the above phenomena are the internal fouling of the gearbox, wear or serious wear of bearings, gears and other components, or damage to the side of the gears.
4、變速箱溫度過高
4. The temperature of the gearbox is too high
行駛過程中電腦顯示報警：變速箱溫度過高;或行駛一段后自己感覺變速箱過熱，甚至燙手。這應該是變速箱內部經常超負荷運轉，無法有效控溫造成的。
In the course of driving, the computer display alarm: the temperature of the transmission is too high; or after a period of driving, I feel overheated transmission, or even hot. This should be caused by the overload operation of the gearbox and the failure to control the temperature effectively.
5、車子發生打滑或沖擊
5. A car is skidding or impacting
如果掛上D檔或R檔車子不走，或者車子反應很遲緩后沖擊，或者發動機轉速很高但車速卻很慢，就意味著變速箱內部的機械傳動部分出了問題。
If the D or R gear does not go, or the car's reaction is slow, or the engine speed is very high, but the speed is slow, it means the mechanical transmission part of the gearbox is out of problem.
6、變速箱體內產生異味
6. The odor produced in the gearbox
變速箱體是靠液壓油來工作的，當油溫過高時，會產生一些燃燒，這些異味會傳出來，這就說明變速箱體內的某些執行部件工作不正常。
The gearbox is operated by hydraulic oil. When the oil temperature is too high, some burning will be produced. These peculiar smell will be passed out. This shows that some of the execution parts in the gearbox are not working properly.
7、引擎空轉
7. Engine empty
引擎空轉一般發生在兩種情況：
Engine turnover is generally in two cases:
(1)、在車輛在平穩種突然出現引擎空轉的現象，在車速慢下來有恢復正常，這種情況一般說明變速箱在短的時間內突然從高檔位降為低檔位，問題有可能處在控制系統或者散熱系統上，變速箱本身沒有問題。
(1), in the vehicle in a stable type of sudden emergence of the phenomenon of engine empty, the speed slowed down to normal, this situation generally shows that the gearbox in a short time suddenly from high level down to low level, the problem may be in the control system or heat dissipation system, the gearbox itself has no problem.
(2)、在加速的過程中或者在換檔的過程中出現短暫的打滑空轉現象，直觀的感覺是后者沒有前者那么厲害，實際上確實恰恰相反，后者的問題多半處在變速箱內的離合器等相關環節上，處理起來出要變速箱徹底解體檢修，時間成本消耗都要比前者多出許多。
(2), in the process of acceleration or in the process of shift, there is a short skidding phenomenon. The intuition is that the latter is not as strong as the former. In fact, it is really the opposite. The latter is mostly in the clutch and other related links in the gearbox, and the transmission is completely disintegrated and overhauled. The cost is much more than the former.
8、汽車不能行駛
8, the car can't drive
無論將換擋桿位于倒擋還是前進擋，汽車都不能行駛;又或者冷車起動后汽車能行駛一小段路程，但熱車狀態下汽車不能行駛。遇到這樣的情況可能是：1、自動變速箱漏油嚴重，嚴重缺油;2、換擋桿和手動閥搖臂之間的連桿或拉索松脫，手動閥保持在空擋或停車擋位置;3、進油濾網堵塞;4、主油路嚴重泄漏;5、油泵損壞。建議去4S店維修保養。
Whether the shift lever is in the reverse or the forward gear, the car can't drive, or the car can run for a short distance after the cold car starts, but the car can't drive under the hot car. The situation may be: 1, the automatic transmission oil leakage serious, serious oil shortage; 2, the shift lever and the manual valve rocker between the connecting rod or cable loose, the manual valve remains in the air or parking gear position; 3, oil filter screen blockage; 4, main oil road leakage; 5, oil pump damage. It is suggested to go to 4S shop for maintenance.
變速箱誤判的危害
The harm of miscarriage of gear box
自動變速箱系統跟發動機系統及ABS系統等有緊密的通信，電腦系統牽扯面非常復雜，另外機械方面精度非常高。所以變速箱系統出現故障可能涉及多方面原因，一旦出現故障，建議車主到汽車維修店，由經驗豐富的技師進行診斷。
Automatic transmission system has close communication with engine system and ABS system, the computer system is very complicated, and the mechanical precision is very high. Therefore, the failure of the gearbox system may involve many reasons. Once the failure occurs, it is suggested that the owner of the vehicle go to a professional car repair shop and be diagnosed by an experienced professional technician.
