自動變速箱油底滲漏，導致變速箱油漏光，或者是操縱手柄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，又或者是油泵進油濾網堵塞，油泵損壞等原因，都會導致車輛出現不走車故障。今天小編總結了三個自動變速箱不走車維修實例，供廣大車主參考。
The automatic transmission oil bottom leaks, causing the transmission oil to leak out, or the connecting rod or cable between the joystick and the rocker arm of the manual valve is loose, the manual valve remains in the neutral or parking position, or the oil inlet filter screen of the oil pump is blocked, the oil pump is damaged, and other reasons will lead to the non running fault of the vehicle. Today, Xiaobian summarized three examples of non running maintenance of automatic transmission for the reference of car owners.
行駛里程：160214km
Mileage: 160214km
故障現象：不走車，掛R擋時車身會一聳一聳的。
Fault phenomenon: if you don't leave the car, the car body will shrug when you engage r gear.
故障分析：對CVT變速箱的檢查，先要檢查壓力缸是否存在卸壓現象，油泵限壓閥是否訊在拉傷發卡，后要檢查的就是閥體。維修技師對該車做檢測時，并未發現存在故障碼，一圈測試下來，初步判斷該車故障是由于主鏈輪轂卸壓發卡導致的。
Fault analysis: for the inspection of CVT gearbox, first check whether there is pressure relief in the pressure cylinder, whether the pressure limiting valve of the oil pump is strained and stuck, and then check the valve body. When the maintenance technician tested the car, he did not find any fault code. After a round of testing, it was preliminarily judged that the fault of the car was caused by the main chain hub pressure relief and card issuance.
故障維修：拆解后發現，主鏈輪轂卸壓嚴重，已經卡住，鏈條拉傷。此車在進京美之前，更換過閥體，維修技師排查發現步進電機閥內部彈簧沒有安裝。后，更換主副壓力缸及鏈條、閥體后，裝復試車，故障排除。
Fault maintenance: after disassembly, it was found that the main chain hub was seriously depressurized and had been stuck, and the chain was strained. Before entering Jingmei, the valve body of this car was replaced, and the maintenance technician found that the internal spring of the stepping motor valve was not installed. After that, replace the main and auxiliary pressure cylinders, chains and valve bodies, and then reassemble them for commissioning and troubleshooting.
行駛里程：186161km
Mileage: 186161km
故障現象：不走車
Symptom: no running
故障分析：該車送至維修廠后，維修技師對其做了檢測，發現該車掛檔沒有任何反應，未顯示有任何油壓，初步判斷應該是油泵軸損壞。
Fault analysis: after the car was sent to the maintenance factory, the maintenance technician tested it and found that there was no response when the car was in gear, and no oil pressure was displayed. It was preliminarily judged that the oil pump shaft was damaged.
故障維修：抬下變速箱后，發現該車的油泵軸斷了，導致供油中斷，另外，行星架中間軸承也被磨掉了。更換受損件后，清洗其他元件，裝復試車，故障排除。
Fault maintenance: after lifting down the gearbox, it was found that the oil pump shaft of the car was broken, resulting in the interruption of oil supply. In addition, the middle bearing of the planet carrier was also worn off. After replacing the damaged parts, clean other components, reassemble and test run, and troubleshoot.
行駛里程：120079km
Mileage: 120079km
故障現象：掛前進擋D擋不走車，掛2擋能正常行駛。
Fault phenomenon: the car does not move when in gear d, and it can drive normally when in gear 2.
故障分析：
濟南自動變速箱維修技師對該車做完基本檢測后，初步判斷為內部摩擦片燒毀，主油壓電磁閥存在損壞。
Fault analysis: after the basic inspection of the vehicle, the maintenance technician of Jinan automatic transmission preliminarily judged that the internal friction plate was burned and the main oil pressure solenoid valve was damaged.
故障維修：拆解變速箱發現該車的前進擋摩擦片與倒檔摩擦片燒毀嚴重，電磁閥損壞，無繼續使用價值。更換摩片與閥體后翻新變矩器，清洗各元件，裝復試車，故障排除。
Fault maintenance: after disassembling the gearbox, it was found that the forward and reverse friction plates of the vehicle were seriously burned, and the solenoid valve was damaged, which was of no further use value. After replacing the friction plate and valve body, refurbish the torque converter, clean all components, reassemble and test run, and troubleshoot.
That's all for the three examples of automatic transmission maintenance failure. If you don't understand this content, please consult http://m.gxrbbs.com Let's go.
