Possible causes of kicks in the Hyundai Getz gearbox:
1. Low level or contamination of transmission fluid:
* Check the fluid level and add if necessary.
* Replace the fluid if it turns dark or has a burning smell.
2. Faulty shift solenoid:
* Controls gear shifting and malfunction may result in kicking.
3. Clogged hydraulic unit control valve:
* Regulates the flow of fluid in the gearbox and clogged fluid can cause shocks.
4. Worn clutches or steel discs:
* Responsible for transferring power from the engine to the gearbox. Their wear can lead to slipping and kicking.
5. Malfunctions in the electronic control unit:
* Controls the operation of the transmission and its malfunction may cause incorrect gear shifting.
6. Faulty input or output shaft speed sensor:
* Provides information about the speed of rotation of the shafts, and their malfunction can lead to improper operation of the transmission.
7. Worn torque converter:
* The clutch between the engine and gearbox, which can wear out and cause kicking.
8. Faulty gearbox housing:
* May cause transmission fluid leaks and other kicking problems.
Steps to eliminate kicks:
1. Check the level and condition of the transmission fluid.
2. Have a mechanic diagnose it using an OBD-II scanner.
3. Replace any faulty components such as solenoids, valves and sensors.
4. Consider repairing the torque converter or rebuilding the transmission if necessary.
