Possible reasons:
1. Transmission oil level is low: Check the transmission oil level and top up if necessary.
2. Friction Disc Wear: With age and mileage, friction discs can wear out, resulting in slipping and jerking when shifting gears.
3. Malfunctioning valve body or solenoids: These components control the flow of fluid in the transmission and can fail, causing kicking.
4. Contaminated Transmission Oil: Over time, the transmission oil can become contaminated with metal shavings and other particles, which can cause poor performance.
5. Electronic Problems: Electrical problems in the transmission control unit can disrupt the operation of the equipment and cause kicking.
6. Worn or damaged shift cable: If the shift cable is worn or damaged, it can cause difficult or inaccurate shifting.
7. Engine or Transmission Problems: Problems with the engine or transmission can affect the transmission and cause kicking.
What to do:
* Check the gearbox oil level: Check the oil level using the dipstick or through the inspection hole.
* Replace oil and filter: If the oil is dirty or worn, replace it and install a new filter.
* Diagnose faults: Have a qualified mechanic diagnose and repair faults in the valve body, solenoids or electronics.
* Consider transmission repair or replacement: If other solutions have failed, consider transmission repair or replacement.
Warning: Kicking gears may be a sign of a serious problem. Don’t ignore this problem and take it to a mechanic as soon as possible to prevent further damage.
