When you engage an automatic transmission gear in Skoda cars, various knocking noises may occur, which may indicate various problems.
Possible causes and solutions:
1. Low transmission fluid level:
* Check the transmission fluid level. If it is low, add fluid recommended by the manufacturer.
* Fluid leakage can cause a decrease in pressure and knocking noises when shifting gears.
2. Worn hydraulic components:
* The hydraulic pump, solenoids and other components can wear out over time, resulting in low pressure and knocking noises.
*These components may need to be repaired or replaced.
3. Faulty speed sensors:
* Faulty speed sensors can send incorrect data to the transmission control module, resulting in incorrect gear shifts and knocking noises.
* Check the speed sensors and replace them if necessary.
4. Worn friction linings:
* Friction linings in automatic transmissions wear out over time, which can lead to slipping and knocking.
* Friction linings may need to be repaired or replaced.
5. Faulty oil pan:
* The oil pan can become deformed over time, causing fluid to leak and reduce pressure.
* Check the oil pan and replace it if necessary.
6. Problems with electronics:
* Faulty electrical components, such as the electronic control unit (ECU), can cause the automatic transmission to malfunction and cause knocking noises.
* Run diagnostics using a trouble code scanner to identify potential electrical problems.
7. Torque converter defects:
* The torque converter may be damaged, resulting in vibration and knocking noises when shifting gears.
* The torque converter may need to be repaired or replaced.
If you notice a knocking noise when shifting gears in your Skoda, it is highly recommended that you take it to a qualified mechanic to diagnose and fix the problem. Continuing to use a faulty automatic transmission can result in further damage and costly repairs.
