What should I do if the gearbox is abnormal?
1. Incomplete clutch separation. This phenomenon often occurs in manual gearboxes. To put it bluntly, you can upshift by stepping on the clutch without stepping on the end. It is also possible that the clutch pedal was released when shifting gears.
Doing so for a long time will not only make abnormal noise and wear the clutch, but also shorten the service life of the gearbox and clutch when used for a long time.
Solution: standardize the gear shifting operation. Be sure to pedal the clutch to the bottom, then put it in gear, put it in gear, and then release the clutch pedal.
2. The gear is damaged or the connecting bolt is broken. If this is the case, the phenomenon is generally that the rear axle (differential bearing seat) makes a "clank" sound during driving, and the abnormal sound disappears when it returns to neutral.
Solution: Let professionals check and determine what the problem is, and then analyze it according to specific problems.
3. The transmission pad is broken. If the foot pad of the gearbox is broken, it will not only make abnormal noise, but also vibrate badly, which will produce * * * vibration with the car body, making the vibration inside the car even greater.
If it is completely broken, it will affect the gear. Once the gear is engaged, the gearbox will shake and the impact can be felt in the car.
Solution: Replace the transmission gasket.
The hydraulic torque converter of the gearbox is broken, showing 1, and the oil temperature of the torque converter is too high: the high oil temperature of the engine is mainly due to the fact that the oil temperature exceeds 120℃ when working, and it feels very hot by hand, mainly because the oil level of the transmission is too low; The water level in the cooling system is too low; If the oil pipe and cooler are blocked or dirty, and the oil temperature is too high during driving, stop immediately, let the engine run at idle speed, and check whether the cooling system leaks. If the oil temperature drops slowly, it may be because the free wheel is stuck and the guide wheel is locked, so the hydraulic torque converter should be disassembled for inspection.
2. The oil supply pressure of the torque converter is too low: when the engine throttle is fully open, the oil pressure at the inlet of the torque converter is still lower than the standard value, which may be caused by insufficient oil supply or the oil level is lower than the plane of the oil suction port. It is necessary to check the oil level in time. If the inlet and outlet pipes are well sealed, check the operation of the inlet and outlet pressure valves, check the torque converter, check the installation of the oil return pipe, and check whether there is foam in the hydraulic oil.
3. Torque converter oil leakage: Torque converter oil leakage is also one of the important manifestations of torque converter damage, which may be caused by loose connecting bolts at the connection between pump wheel and hub or aging or damage of seals. If oil leakage is found, check the location of oil leakage in time. If there is oil leakage at the joint between the torque converter and the engine, it means that the connecting bolt between the pump wheel and the pump wheel cover is loose or the sealing ring is aging, which should be solved in time.
