汽車自動變速箱一旦有故障，應及時送廠檢修，不可帶故障運行，以免造成更大的損失。下面
濟南自動變速箱維修人員就來講講汽車自動變速箱的故障診斷與檢測方式吧。
Once there is a fault in the automatic transmission, it should be sent to the factory for maintenance in time. It is not allowed to run with the fault to avoid greater loss. Now Jinan automatic transmission maintenance personnel will talk about the fault diagnosis and detection methods of automatic transmission.
1、根據故障現(xiàn)象分析，進行故障現(xiàn)象確認。
1. Confirm the fault phenomenon according to the fault phenomenon analysis.
2、如果是電控自動變速箱，而且故障指示燈亮，首先進行自我診斷讀取故障碼，排除故障碼所代表的故障。
2. If it is an electronically controlled automatic transmission and the fault indicator light is on, first conduct self diagnosis and read the fault code to eliminate the fault represented by the fault code.
3、進行自動變速箱和發(fā)動機的常規(guī)檢查，主要項目有：
3. Carry out routine inspection for automatic transmission and engine. The main items are:
a．檢查油面高度和油質。
a. Check the oil level and quality.
b．檢查并調整加速踏板拉線和節(jié)氣門位置傳感器。
b. Check and adjust the accelerator pedal cable and throttle position sensor.
c．檢查選檔手柄連動桿系。
c. Check the gear selector linkage.
d．檢查空檔起動開關及檔位開關。
d. Check the neutral start switch and gear switch.
e．檢查發(fā)動機怠速。
e. Check the engine idle speed.
f．檢查輪胎氣壓及傳動系其他相關部位。
f. Check the tire pressure and other relevant parts of the power train.
4、進行失速試驗，檢查發(fā)動機和自動變速箱內部機械技術狀況。
4. Carry out stall test and check the internal mechanical and technical conditions of the engine and automatic transmission.
5、手動換檔試驗；確定故障是在電控部分還是在自動變速箱內部。
5. Manual shift test; Determine whether the fault is in the electronic control part or in the automatic transmission.
6、進行時滯試驗，檢查日動變速器的離合器、制動器的磨損情況。
6. Carry out time delay test to check the wear of the clutch and brake of the daily transmission.
7、電子控制系統(tǒng)自我診斷和組件及線路檢測。
7. Self diagnosis of electronic control system and detection of components and circuits.
8、油壓測試，檢查油泵、調壓閥、調速器油壓和油路壓力。
8. Oil pressure test, check the oil pump, pressure regulating valve, governor oil pressure and oil circuit pressure.
9、進行道路試驗，檢查自動換檔點、有無異常噪聲、振動、打滑以及發(fā)動機的制動作用等。
9. Carry out a road test to check the automatic shift point, whether there is abnormal noise, vibration, slip and the braking effect of the engine.
10、綜合各項測試結果，分析和判斷故障原因和部位。
10. Analyze and judge the cause and position of the fault based on the test results.
In addition, it should be known that the failure of the automatic transmission is related to the engine, electronic control system and automatic transmission. Therefore, it should be confirmed that the failure is inside the automatic transmission before it can be disassembled for maintenance. More notes on our website http://m.haoyouyuan.com.cn Consult!
