作为修车一族来说，我们时常会遇上关于自动变速箱的故障问题，那么怎么样才能快速准确的判断出问题所在呢?诊断的思路是怎么样的?今天
济南自动变速箱维修人员来讲讲入档迟、入档死火、入档冲击是怎么回事。
As a car repairer, we often encounter problems with automatic transmission, so how can we quickly and accurately determine the problem? What is the idea of diagnosis? Today, Jinan automatic transmission maintenance personnel will talk about the reasons of late shift, misfire and shock.
测试入档标准是启动引擎、怠速、踩住刹车、入档，正常的的情况是1-1.2秒的时间内有入档的感觉、放开刹车踏板，在不踩油门踏板的情况下车辆会慢慢起步并逐步提取到10-20公里/小时的车速，这是一部正常的入档标准，如果入档后超过2秒钟以上即定位入档延迟，这种情况需要立即检修。
The test gear-in standard is to start the engine, idle, hold the brake, and shift in. The normal condition is to feel the gear-in within 1-1.2 seconds, release the brake pedal, and the vehicle will start slowly and gradually extract the speed of 10-20 km/h without stepping on the accelerator pedal. This is a normal gear-in standard. If the gear-in delay is located more than 2 seconds after the gear-in, this situation needs to be repaired immediately.
如果入档有强烈的冲击感觉即定位入档冲击，需要说明的是任何的自动变速箱入档都有一定程度的冲击感觉，如果丝毫的感觉都没有，反而说明内部有故障，但这个冲击比较大则是不能够接受的，引发的这个问题很复杂包括除变速箱以外的很多方面;入档死火的情况是入档时引擎会死火，这种问题在冷车时比较明显，引发这个问题有变速箱的问题也有其他车身系统的问题。
If there is a strong impact feeling in the gear shift, that is, the positioning impact, it should be noted that any automatic transmission has a certain degree of impact feeling in the gear shift. If there is no feeling at all, it indicates that there is an internal fault, but the impact is relatively large, which is unacceptable. The problem caused is very complex, including many aspects except the transmission; The case of misfire when shifting in is that the engine will misfire when shifting in. This problem is more obvious when the car is cold. This problem is caused by the gearbox and other body systems.
起步无力、不能起步、起步抖动测试起步的标准有两个其一是测试“爬行”，其二是测试测试提速爬行是指入档后放开刹车、不睬油门踏板、直路行驶测试在怠速情况下的车辆起步和行驶，正常的车辆能够车辆逐步提速到20公里/小时的时速，如果不能够达到这个标准一般先要检查引擎怠速是否过低，正常的700转左右，其二检查是否轮胎气压是否过低，如果以上正常说明变速箱系统存在故障。
There are two standards for starting test: weak starting, unable to start, and starting jitter. One is to test "creep". The other is to test acceleration creep, which means to release the brake after entering gear, ignore the accelerator pedal, and drive the vehicle straight. The normal vehicle can gradually increase the speed to 20 km/h, and if it can not meet this standard, it is necessary to check whether the engine idle speed is too low, The second is to check whether the tire pressure is too low. If the above is normal, it indicates that there is a fault in the transmission system.
测量起步提速的方法是入档、松刹车、按照小、中、大油门的程序分三次测试起步提速的感觉，正常的情况是车辆的车速同引擎的转速保持一定的比例加速，具体感觉根据引擎排量的大小、车辆的重量、变速箱的档位有很大的关联，整个提速过程平稳顺畅、无抖动、无冲击为正常。
The way to measure the starting acceleration is to shift in gear, release the brake, and test the feeling of starting acceleration in three times according to the procedure of small, medium and large throttle. The normal situation is that the vehicle speed keeps a certain proportion of the engine speed to accelerate. The specific feeling is closely related to the size of the engine displacement, the weight of the vehicle, and the gear of the transmission. The whole acceleration process is smooth, without jitter and impact.
