Applicable scenery: the vehicle has experienced motor quality anomalies, such as shaking and slipping, requiring an in-depth understanding of the principles of failure。
Emotional tone: professional, rational, focus on typical failures。
If a failure light is an early warning, the “real hammer” in which the failure is occurring is the shock, the sense of shock, and even the power disruption that occurs in the vehicle. The following failure points are most common for the type of car carrying the at automatic transmission vans under the buick flag (e. G., junway, junctu, ankwe, etc.)。
Valve failure: the "first killer" that drives
Valve failure is highly representative of the bek model. The impurities in the fluids may cause the valve core to stagnate after a long period of operation。
Typical symptoms: the vehicle suffered a marked setback at a low speed (20-50 km/h), especially when 2-3 and 3-4 were blocked, accompanied by a slight “discussion”. As one of the owners of the ankorway plus described it: "dithered, staggered, like a slow-down belt."。
Depth cause: valve card delay leads to pressure instability in the switch and the timing of integration of the clutch。
Solutions: light card delay can attempt to disassemble the cleaning valve and replace the specialized oil; heavy wear requires replacement of the total valve, usually at a cost of 2000-3,000 yuan
Fracture of the clutch piece: dereliction of power “transmitters”
The pieces are consumables and are naturally worn as the mileage increases. In particular, under frequent urban congestion, semi-momentation and wear and tear increase. The pieces are consumables and are naturally worn as the mileage increases. In particular, under frequent urban congestion, semi-momentation and wear and tear increase。
Typical symptoms: at acceleration, the engine is felt to be in the air, the speed of the vehicle is slowly rising (i. E. Sliding) or there is a clear lack of power at the uphill. It's a common problem for blanche cars。
Depth cause: when the pieces of the clutch are worn to the limit, they cannot be pressed, resulting in the complete transmission of engine power to the wheel。
Solutions: the gearbox must be dismantled, a whole new piece of centrifuge must be replaced, and the contamination of other parts by iron scrap must be checked
Computer failure in gearbox: “disability” of vehicle
In some of the bekken cars, computer failure of the gearbox is frequent. The computer may cause control logic disorder through welding and damage to components
Typical symptoms: the dashboard suddenly hints to repair the gear transformer, the vehicle is locked up in an unstoppable position, or the vehicle suddenly jumps back into the space in the middle of the journey, which is extremely dangerous。
Depth cause: computers are unable to read and output the signals accurately, resulting in the transmission box being “unsure”。
Solutions: maintenance or replacement of gearbox computers and programming matching of new computers
Dispersion system bad: the heat is invisible
The high temperature of the gearbox is also a common cause of alarm。
Typical symptoms: after a long run of high speed or heavy driving, the power response is delayed and even the smell of a big coke。
Depth cause: vector radiator jamming or cooling fan failure, resulting in sharp increase in fluid temperature and reduced lubrication performance。
Solutions: inspection and cleaning of radiators, repair or replacement of dispersed fans
