Shift phenomenon occurs frequently

　　車主問：我開的是一輛尼桑天籟，平時掛1、2、3擋都正常，換4擋的時候會出現(xiàn)掉擋的情況，輕微提速也會出現(xiàn)這種情況，開到120公里/小時的時候，也有這樣的情況。請問是什么原因？

　　The owner asked: I am driving a Nissan Sound, usually hanging 1, 2, 3 gear are normal, shift 4 gear will occur when the gear will be off, slightly speed-up will occur this situation, to 120 km/h, there is also such a situation. What is the reason?

　　專家解答：首先確認(rèn)車輛自動變速箱油的使用時間，正常使用情況下，建議每隔6萬公里更換一次，極限更換里程為10萬公里。若自動變速箱油在允許使用的時間范圍內(nèi)，則予以檢查油液顏色。

　　Expert Answer: First of all, confirm the use time of vehicle automatic transmission oil. Under normal conditions, it is recommended to replace it every 60,000 kilometers, with a limit of 100,000 kilometers. If the automatic transmission oil is within the allowable time range, the oil color will be checked.

　　若顏色為暗紅色且伴有煳味則可能是由于自動變速箱內(nèi)部摩擦片磨損嚴(yán)重，從而導(dǎo)致4擋掉擋情況的出現(xiàn)。建議車主做一次自動變速箱的動力測試。

　　If the color is dark red and accompanied by flavor, it may be due to the serious wear of friction discs inside the automatic transmission, which leads to the occurrence of 4-stop situation. It is suggested that the owner should do a dynamic test of the automatic transmission.

　　為啥加油時會跑偏

　　Why do you run off when refueling?

　　車主問：我開的是一輛2003年千里馬1.3手動擋汽車，目前行駛了12萬公里。在加油時，油門給得大點就往右跑偏，勻速給油就不跑偏，請問這是什么問題？

　　The owner asked: I was driving a 1.3 manual gear car in 2003, which currently travels 120,000 kilometers. When refueling, if the throttle is bigger, it will run to the right, and if the fuel is given at a uniform speed, it will not run away. What is the problem?

　　專家解答：由于該車輛已行駛了12萬公里，右前輪的底盤連接部件(如球頭)有可能產(chǎn)生較大的間隙，同奔奔[綜述 圖片 論壇]鈾俚那榭魷攏瞪磯抖隙ń銜緦遙⑶掖葜戀著塘硬考可能導(dǎo)致瞬間四輪定位數(shù)據(jù)超出范圍的情況出現(xiàn)。建議車主先將車輛進行四輪定位并對車輛底盤做一次全面的檢查，若定位后可恢復(fù)正常行駛，則不用更換底盤任何零部件。

　　Expert Answer: Because the vehicle has traveled 120,000 kilometers, chassis connection parts of the right front wheel (such as ball head) may have large clearance. The situation that the instantaneous four-wheel positioning data exceed the range may occur when the vehicle runs together. It is suggested that the owner should first carry out four-wheel positioning and make a comprehensive inspection of the chassis of the vehicle. If the vehicle can resume normal driving after positioning, no parts of the chassis need to be replaced.
                                             

　　油門踏板輕微抖動

　　Accelerator pedal shaking slightly

　　車主問：我開的是一輛新買的致勝2.3時尚款，較近發(fā)現(xiàn)著車后啟動時在1擋換2擋后，油門踏板會有輕微抖動，之后就沒有了，但是如果重新啟動發(fā)動機，仍會有輕微抖動，請專家指教。

　　The owner asked: I was driving a newly purchased Victory 2.3 fashion model. Recently, I found that the throttle pedal would shake slightly after shifting from one gear to two gear at the start of the car, and then it would disappear. But if the engine was restarted, it would still shake slightly. Please consult experts.

　　專家解答：初步判斷車主描述的故障為自動變速箱的換擋沖擊，通過車身將抖動傳遞至油門踏板上的。此種現(xiàn)象應(yīng)屬于正?，F(xiàn)象。但因用戶是新車，建議用專用儀器檢查一下節(jié)流閥體的數(shù)據(jù)和自動變速箱數(shù)據(jù)是否正常，并由維修技師陪同路試。

　　Expert Answer: Preliminary judgment of the car owner described the fault as automatic transmission shift impact, through the body will be transmitted to the throttle pedal jitter. This kind of phenomenon should belong to the normal phenomenon. However, since the user is a new car, it is suggested that special instruments be used to check whether the data of throttle valve body and automatic transmission are normal, and professional maintenance technicians should accompany the road test.
