What is the fault of transmission malfunction?

"Transmission malfunction" shows a transmission failure. The reasons for the failure are: 1. The temperature of the automatic transmission is too high; 2. The automatic transmission has been used for a long time; 3. Water has entered the automatic transmission; 4. Oil The surface height difference is large.

Transmission malfunction shows a transmission failure.

Don't be nervous when this fault occurs. First check whether there is transmission oil leakage. Look down at the bottom of the car to see if there is any fluid flowing out. If there is no leakage, it is recommended to park the car in a safe area, open the hood and pull out the transmission dipstick. When the vehicle is idling, check whether the transmission oil level is at the normal position.

If the fluid level is basically normal, it is recommended that you do not continue driving to avoid damaging the internal parts of the gearbox and increasing unnecessary expenses. Please call the 4S shop or contact the repair shop to tow the vehicle to the shop for inspection and repair.

Causes of gearbox failure:

1. The temperature of the automatic gearbox is too high (when the temperature is too high, the oil will turn brown or dark red)

2. If the automatic transmission is used for a long time (generally two years or 20,000 kilometers) if not replaced, the oil will deteriorate; or the torque converter locking function will fail; or the automatic transmission radiator will be clogged or there will be heat dissipation problems. Any bend will cause the automatic transmission to overheat.

3. Water enters the automatic transmission (the oil will appear milky after water enters the transmission). There are generally two situations in which water enters the automatic transmission. The first one: the engine coolant enters the automatic transmission through the radiator. ;Second type: Rainwater or car wash water enters through the automatic transmission vent. After water enters the automatic transmission, the vehicle failure will not be displayed immediately, so the car owner must observe the transmission oil in real time.

4. The oil level difference is large (in this case, the gearbox oil will produce a lot of foam). If the oil level is too low, the oil pump will suck in air to mix the oil and air; if the oil level is too high, it will The planetary gears and other rotating parts are immersed in the gearbox, causing oil agitation. Whether it is too high or too low, it will cause the automatic transmission oil to deteriorate and cause failure.
