Causes of shift impact of Mercedes-Benz (review)

Mercedes-Benz is famous for its comfort, but it will be embarrassing if the shift is not smooth, especially when there are passengers. Therefore, let's sum up the reasons for the frustration of Mercedes-Benz gear shifting, hoping to solve the troubles quickly. Shift shock refers to the situation that power transmission is not smooth, and the specific reasons are: 1, throttle failure, such as throttle damage or need to be cleaned. There is something wrong with the engine computer. 3. Failure of the transmission shaft, such as damage of the connecting rubber pad. 4. Transmission failure is the main component causing the problem, which is mainly introduced as follows: a. Transmission oil problems, such as high oil level, low oil level, water inflow, filter blockage, etc. B, transmission shift logic problems, such as poor performance of the control unit or the need to re-match the shift learning value. C, transmission valve body problems, such as hydraulic control solenoid valve, shift solenoid valve, hydraulic valve body slide valve stuck. D, torque converter problems, such as torque converter lock-up clutch need to learn to match again. E, other shift actuator problems, such as clutch plate wear and burn or brake spring damage. 5. Communication failure between engine computer and transmission control module. Abnormal phenomena such as engine setback, impact and slipping are mostly caused by poor adjustment of gearbox body and hydraulic pressure, so special attention should be paid to the maintenance and use of gearbox at ordinary times. For example, it's best to change the transmission oil immediately and put on R gear after parking. Although Mercedes-Benz can directly switch to R gear at low speed, it is indispensable for everyone.
