Shift phenomenon occurs frequently

　　車(chē)主問(wèn)：我開(kāi)的是一輛尼桑天籟，平時(shí)掛1、2、3擋都正常，換4擋的時(shí)候會(huì)出現(xiàn)掉擋的情況，輕微提速也會(huì)出現(xiàn)這種情況，開(kāi)到120公里/小時(shí)的時(shí)候，也有這樣的情況。請(qǐng)問(wèn)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(zhuān)家解答：首先確認(rèn)車(chē)輛自動(dòng)變速箱油的使用時(shí)間，正常使用情況下，建議每隔6萬(wàn)公里更換一次，極限更換里程為10萬(wàn)公里。若自動(dòng)變速箱油在允許使用的時(shí)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(dòng)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(chē)主做一次自動(dòng)變速箱的動(dòng)力測(cè)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(shí)會(huì)跑偏

　　Why do you run off when refueling?

　　車(chē)主問(wèn)：我開(kāi)的是一輛2003年千里馬1.3手動(dòng)擋汽車(chē)，目前行駛了12萬(wàn)公里。在加油時(shí)，油門(mén)給得大點(diǎn)就往右跑偏，勻速給油就不跑偏，請(qǐng)問(wèn)這是什么問(wèn)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(zhuān)家解答：由于該車(chē)輛已行駛了12萬(wàn)公里，右前輪的底盤(pán)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(chē)主先將車(chē)輛進(jìn)行四輪定位并對(duì)車(chē)輛底盤(pán)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(pán)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(mén)踏板輕微抖動(dòng)

　　Accelerator pedal shaking slightly

　　車(chē)主問(wèn)：我開(kāi)的是一輛新買(mǎi)的致勝2.3時(shí)尚款，較近發(fā)現(xiàn)著車(chē)后啟動(dòng)時(shí)在1擋換2擋后，油門(mén)踏板會(huì)有輕微抖動(dòng)，之后就沒(méi)有了，但是如果重新啟動(dòng)發(fā)動(dòng)機(jī)，仍會(huì)有輕微抖動(dòng)，請(qǐng)專(zhuān)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(zhuān)家解答：初步判斷車(chē)主描述的故障為自動(dòng)變速箱的換擋沖擊，通過(guò)車(chē)身將抖動(dòng)傳遞至油門(mén)踏板上的。此種現(xiàn)象應(yīng)屬于正?，F(xiàn)象。但因用戶(hù)是新車(chē)，建議用專(zhuān)用儀器檢查一下節(jié)流閥體的數(shù)據(jù)和自動(dòng)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.
