轎車自動變速器的故障往往是由發(fā)動機(jī)和電控系統(tǒng)引起，也有是由自動變速器本身引起，在進(jìn)行檢修之前，根據(jù)由簡入繁、由易到難的原則，應(yīng)先將故障部位大致分清（即發(fā)動機(jī)故障還是自動變速器故障）。若變速器帶有自我診斷系統(tǒng)，則應(yīng)先進(jìn)行自診。檢查自動變速器鼓掌一般按以下程序進(jìn)行：

The faults of automatic transmissions in cars are often caused by the engine and electronic control system, as well as by the automatic transmission itself. Before conducting maintenance, according to the principle of simple to complex and easy to difficult, the fault location should be roughly distinguished (i.e. engine fault or automatic transmission fault). If the transmission is equipped with a self diagnostic system, self diagnosis should be performed first. The inspection of automatic transmission applause is generally carried out according to the following procedure:

（1）先進(jìn)行基礎(chǔ)檢查：如變速器油的質(zhì)量和數(shù)量是否合適；節(jié)氣門拉線記號是否正確；變速操縱桿系及空擋啟動開關(guān)是否工作正常；空轉(zhuǎn)轉(zhuǎn)速是否合適；輪胎氣壓是否標(biāo)準(zhǔn)

(1) First, conduct a basic inspection: such as whether the quality and quantity of transmission oil are appropriate; Is the throttle cable marked correctly; Is the gear lever system and neutral start switch working properly; Is the idle speed appropriate; Is the tire pressure standard

（2）然后進(jìn)行時速試驗(yàn)：以檢查發(fā)動機(jī)和自動變速器的性能。

(2) Then conduct a speed test to check the performance of the engine and automatic transmission.

（3）時滯試驗(yàn)：對液壓管道進(jìn)行基礎(chǔ)檢查后，通過液壓試驗(yàn)來確認(rèn)液壓系統(tǒng)是否有故障。

(3) Time delay test: After conducting a basic inspection of the hydraulic pipeline, a hydraulic test is conducted to confirm whether there is a malfunction in the hydraulic system.

（4）非常后道路試驗(yàn)：通過路試，進(jìn)一步檢查變速器的性能，確認(rèn)故障發(fā)生的部位，為變速器檢修提供依據(jù)。

(4) Final road test: Through the road test, further inspect the performance of the transmission, confirm the location of the fault, and provide a basis for transmission maintenance.
