Shift phenomenon occurs frequently

　　车主问：我开的是一辆尼桑天籁，平时挂1、2、3挡都正常，换4挡的时候会出现掉挡的情况，轻微提速也会出现这种情况，开到120公里/小时的时候，也有这样的情况。请问是什么原因？

　　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?

　　专家解答：首先确认车辆自动变速箱油的使用时间，正常使用情况下，建议每隔6万公里更换一次，极限更换里程为10万公里。若自动变速箱油在允许使用的时间范围内，则予以检查油液颜色。

　　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.

　　若颜色为暗红色且伴有煳味则可能是由于自动变速箱内部摩擦片磨损严重，从而导致4挡掉挡情况的出现。建议车主做一次自动变速箱的动力测试。

　　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.

　　为啥加油时会跑偏

　　Why do you run off when refueling?

　　车主问：我开的是一辆2003年千里马1.3手动挡汽车，目前行驶了12万公里。在加油时，油门给得大点就往右跑偏，匀速给油就不跑偏，请问这是什么问题？

　　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?

　　专家解答：由于该车辆已行驶了12万公里，右前轮的底盘连接部件(如球头)有可能产生较大的间隙，同奔奔[综述 图片 论坛]铀俚那榭鱿拢瞪矶抖隙ń衔缌遥⑶掖葜恋着塘硬考可能导致瞬间四轮定位数据超出范围的情况出现。建议车主先将车辆进行四轮定位并对车辆底盘做一次全面的检查，若定位后可恢复正常行驶，则不用更换底盘任何零部件。

　　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.
                                             

　　油门踏板轻微抖动

　　Accelerator pedal shaking slightly

　　车主问：我开的是一辆新买的致胜2.3时尚款，较近发现着车后启动时在1挡换2挡后，油门踏板会有轻微抖动，之后就没有了，但是如果重新启动发动机，仍会有轻微抖动，请专家指教。

　　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.

　　专家解答：初步判断车主描述的故障为自动变速箱的换挡冲击，通过车身将抖动传递至油门踏板上的。此种现象应属于正常现象。但因用户是新车，建议用专用仪器检查一下节流阀体的数据和自动变速箱数据是否正常，并由维修技师陪同路试。

　　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.
