What's wrong with cars?

Fault-Automatic gearbox oil leakage Fault Cause: Different types of gearboxes have different oil leakage locations. For example, Fukang and Elysee are easy to leak oil at the joint of the middle shell, while Senna and Picasso are easy to leak oil at the front oil seal of the torque converter and oil pump. The main reason for leakage is that the sealing effect of the seal is not good, and sometimes it is caused by pitting and corrosion on the parts. If the leakage is not handled in time, the gearbox will be short of oil for a long time, further causing serious internal damage. Maintenance plan: overhaul the gearbox and replace the seal. The second fault, if you release the brake and don't move, you can start with fuel, but it is accompanied by obvious impact.

Cause of failure: The main reason is that the components responsible for the first oil circuit in the gearbox have pressure relief. For example, E 1 clutch split ring and E 1 clutch piston. If the fault is not repaired in time, it will further damage the oil pressure solenoid valve of the gearbox, thus causing serious damage to the gearbox. Maintenance plan: overhaul the gearbox and replace the first gear related oil circuit components. The vehicle SPT light flashes alternately with the * light.

Cause of failure: 1: The oil pressure solenoid valve is damaged, which makes it impossible to establish normal working oil pressure (no pressurization) inside the gearbox. This kind of fault must be dealt with in time, otherwise it will cause serious burning inside the gearbox in a short time. Maintenance plan: Replace the oil pressure solenoid valve Failure Reason 2: It is usually caused by the failure of the peripheral sensors of the gearbox, such as the gear switch (multi-function switch), the input and output speed sensor, the oil pressure sensor and the throttle position sensor. Maintenance plan: Replace related sensors.
